We turn ideas, patents, and inventions into functional prototypes with a high probability of success.
Most product development companies create wonderful industrial designs but do not support the inventor throughout the entire process.
Our goal is to ensure you are not alone. Just like with the prototype examples you will see here, we will guide you to the market.
The integration of various disciplines in our invention manufacturing lab has allowed us to complete a catalog of more than 200 functional prototypes with a final product appearance.
Would you like to discover some examples of inventions to which we have dedicated time and effort?
Examples of Mechanical Prototypes.
The inventions manufactured in Let's Prototype usually integrate different engineering disciplines. Even so, we define the categories of inventions based on where the most critical points lie.
Mechanical prototypes can carry electronics, artificial intelligence, integrate IOT solutions, but, as a common denominator, they will have a high level of complexity in the design.
Case 01. Prototype of an orange juice squeezing machine with a self-cleaning system.
Innovative products are not only those that radically transform existing solutions.
It is a very good option to transform existing products to incorporate technical improvements that make them easier to use. These additional improvements can also be subject to patents.
Making orange juice with existing machines requires significant effort to sanitize them after each use cycle. Failing to clean them properly can lead to bacteria that may be harmful to health. Moreover, the process of cleaning orange juice machines requires a complex and non-ergonomic disassembly process.
The goal of this product was to design a cleaning system that improves the way machines are currently sanitized.
The main challenges in product design were related to the development of a mechanism capable of automatically managing the waste generated by the squeezed oranges while directing the pure orange juice to a special reservoir. Additionally, both the waste container and the orange juice reservoir needed to be easily removable to ensure that the machine was simple and ergonomic to use.
In addition to having this innovative electromechanical system, the machine features a fluid management system that enables automatic rinsing of its interior, allowing for proper cleaning without any effort from the users.
The manufacturing process of this prototype example was successfully completed.
The results of the invented cleaning system developed in our laboratory show efficient performance, substantially reducing the number of manual cleaning cycles required by the machine.
The waste management system, which was one of the critical aspects in the design conceived by our team of mechanical and electronic engineers, was fully validated through field tests. This allows for systematic waste collection without the need to interrupt service.
Case 02. Legless step for attachment to home and office furniture.
Access to the aerial furniture of kitchens or other home or office environments is usually a problem for the "not so tall". In the same way, we have less and less space available in our homes and offices, so making the most of the space in height, becomes a priority. Many times we do not take advantage of it, because of how difficult it would be to access these aerial furniture.
The invention consists of a structure that is integrated into furniture already democratized in the market. The prototype, as can be seen in the patent, works and integrates into the furniture with mechanical elements available on the market.
The industrial design team of Let's Prototype has achieved a functional prototype that is easily integrated into the furniture available on the market. Users only have to open or close a drawer so that, in two steps and without extraordinary efforts, a prototype of a staircase, aesthetic and minimalist, can be obtained to access the airspaces.
Patented invention US2023/0142882
The step prototype designed for integration into kitchen furniture has been recognized as an innovative invention in Europe and the United States. It is currently protected by a patent at the USPTO, granting its owner 20 years of exclusive rights.
The exploitation rights of this patent are currently under negotiation with the world's leading furniture manufacturers, particularly in Europe.
Case 03. Mobile Cleaning Robot Prototype
Companies specializing in selling refurbished mobile phones dedicate a significant amount of time to the detailed cleaning of the devices.
The cleaning process is typically time- and cost-intensive, making it a significant expense within the financial structure of these companies.
The prototype had to be a lightweight machine, composed of readily available market components, easily assembled, and with very low maintenance costs.
The structure of the cleaning machine prototype is designed with a framework very similar to that used in 3D printers.
At an industrial design level, the profiles and anchors used are commercial components that allow new units of the machine prototype to be assembled without the need for custom-made parts. This design decision accelerates machine production and minimizes investment costs for manufacturing new units.
The mechatronics of the machine designed and manufactured in our prototyping laboratory consists of the control of stepper motors and linear actuators, enabling the handling of devices throughout the cleaning process. Similarly, mechanical clamps are used to flip the devices without the need for human intervention.
Keeping the mobile device securely in a mechanical module during the cleaning process was one of the most significant challenges of the project. This objective was achieved by using an industrial electronic suction cup, which was adapted as the machine's main module.
The robot prototype for mobile device cleaning achieved:
Reduction of device cleaning time by 20% compared to the average time required for manual cleaning by humans.
The quality of device cleaning remained at the same standards achieved by human workers in these positions.
The company was able to improve its profitability by substantially optimizing its structural costs.
Case 04. Ladder with legs for integration into home and office furniture.
Kitchen spaces are becoming increasingly smaller, while users need more tools, kitchen robots, appliances, and utensils.
Overhead cabinets become storage spaces for less frequently used items due to the difficulty of accessing them.
Many people keep small portable ladders or step stools in their kitchens to comfortably access these cabinets.
For this reason, the inventor envisioned creating a foldable ladder that could be integrated into widely available kitchen furniture on the market, especially kitchen cabinets sold by IKEA.
The foldable ladder for kitchen furniture, with legs, was a prototype with a high level of mechanical complexity.
At first glance, it looks like a regular ladder; however, the prototype had to be installed in any IKEA kitchen cabinet. This meant that its folded dimensions, ergonomic usability for extraction and storage, were requirements that added a high level of complexity to the mechanical system.
The ladder prototype designed and manufactured in our invention laboratory meets these characteristics. When folded, the mechanism has a height of less than 10 cm, while its width is ideal for being stored in the space of a standard drawer.
The anchoring system for kitchen furniture is very similar to the accessories sold by IKEA, making it a functional prototype that is highly useful for the market. It eliminates the need for any other tools in the kitchen, which, besides being unattractive, are inconvenient and become obstacles within the space.
The analysis and compliance with existing European regulations for household ladders was another critical challenge in the prototype design process. These regulations define the robustness level of the prototype, the dimensions of the step support area, among other design requirements that added complexity to the prototype design process.
El proceso de fabricación del prototipo ha culminado de forma exitosa.
The ladder prototype for kitchen furniture, with legs, is now a patented invention in the United States US2023/0141156A1.
The exclusive sale of the patent is currently being negotiated with some of the leading furniture manufacturers and distributors in Europe and the USA.
We can take your idea to the next level.
Case 05. Electric Vehicle Charging Cable Retracting Device
The democratization of electric vehicles worldwide presents a great source of business opportunities and new product design.
This prototype example is a practical solution to prevent frequent breakdowns in the charging cables of this type of vehicle.
During charging, the power cable is often dragged along the ground, and this repeated practice causes frequent breakdowns while also posing a safety hazard to the environment.
For this reason, the founders of this startup decided to commission our invention factory for the design of a product that would secure the cable during charging while also serving as a practical device for cable storage and transport.
Our industrial design and mechanical engineering team found inspiration for the design of this product in retractable devices used for collecting hydraulic hoses.
Using some of these principles, a prototype was manufactured capable of retracting more than 5 meters of electrical cable for charging vehicles, taking into account all necessary safety and insulation measures.
The prototype can remain on the ground during charging or be ergonomically and securely attached to the vehicle's structure, thus preventing the cables from getting damaged as frequently due to friction with porous surfaces.
At the same time, this prototype example can be comfortably transported in the vehicle in a much more organized manner.
A mechanical prototype has been achieved, portable, compact, and with a minimalist design that aligns with the design and aesthetic of the most modern and futuristic vehicles.
The invention is protected with a Utility Model in Spain. Application No. ES1289374U.
The prototype is currently in the industrialization phase, to be manufactured in large quantities and begin its commercialization process in the market.
Case 06. Retractable Leash Prototype for Pets with Built-in Cleaning System
Picking up pet waste by their owners is not enough to keep public roads completely clean. Additionally, in the case of urine, very few users take the time to pour water and minimize the undesirable stains and, of course, the smell.
This common and problematic situation, combined with other less significant issues such as the lack of lighting in some areas where nighttime dog walks are common, as well as the inconvenience of carrying, in addition to the leash, the waste bags, has been the perfect recipe for shaping an idea, broadly speaking, which has taken form as a result of a co-creation process between the inventor and our industrial design team.
The designed product and manufactured as the first prototype consists of a very aesthetic leash that includes an electronic system to trigger water jets, capable of cleaning the area where pets relieve themselves.
In addition, a low-power LED lighting system has been included in the prototype to achieve the desired illumination in the walking environment.
The prototype features a conventional retractable mechanism, which allows the leash to remain at the desired tension level at all times.
While it is true that this is not one of the most complex mechanical prototypes, the process of manufacturing the first prototype also presented some challenges in terms of the watertightness of the reservoir.
The usual prototype manufacturing techniques have significant limitations for products that need to manage and retain liquid. However, solutions such as resin baths, forming parts with silicone molds, and other techniques allow for achieving the desired results, as was the case here.
The crisis moment caused by the COVID-19 virus was a perfect scenario for the democratization of this product.
The prototype has been marketed since 2020.
The invention was protected through a Utility Model in Spain. Application ES1289374U.
Case 07. Toilet Actuation System
Public restrooms are a source of bacterial transmission due to the nature of the environment.
One of the most common causes of poor hygiene in restrooms is users' reluctance to press the flush buttons. For obvious reasons, these are points that everyone must touch without having sanitized their hands beforehand.
The inventor's idea in this case was to modify the flushing system by adding a mechanism compatible with most models, allowing the extraction of a pedal that could activate the flush without the need to touch the actuator commonly available in the market.
Mechanical system for toilet actuation that, thanks to its use, allows users to activate the flush mechanism of toilet tanks via a pedal, thus avoiding the need for users to touch sanitary fixtures. This functional prototype helps maximize hygiene in public restrooms, from commercial establishments, while also aiming to reduce cleaning costs in these environments.
The challenge of this mechanical invention was to integrate, without drastically altering the widely available toilet flushing systems, a mechanism that would allow the flush system to be activated from an external, ergonomic pedal, requiring minimal construction while ensuring its mechanical strength.
The crisis moment caused by the COVID-19 virus was a perfect scenario for the democratization of this product.
The prototype has been marketed since 2020.
The invention was protected through a Utility Model in Spain. Application ES1289374U.
Case 08. Vertical Drop Pacifier Prototype
Baby pacifiers are a health risk accessory for infants. Their frequent drops represent a major inconvenience for parents, who must continuously sanitize them, and as a result, this is sometimes not done as frequently as needed.
In this case, the inventors have decided to tackle the problem at its root by modifying the product to prevent the nipple from making contact during drops.
Initially, the inventor's idea was to incorporate an electronic system that would protect the nipple upon detecting a falling situation. However, the design and prototyping process carried out in our laboratory led to other solutions.
The object of this invention is to overcome the mentioned drawbacks, especially the issue of the nipple coming into contact with the ground. At Let's Prototype, we have designed a functional prototype that prevents the nipple from touching the ground, regardless of the height from which the pacifier falls.
The solution developed in this prototype example consisted of the insertion of a very subtle retraction mechanism, capable of activating in any falling situation. The slight retraction achieved, combined with an amplification of the pacifier's natural geometry, allowed for the validation of the nipple protection functionality.
Among the main challenges of this prototype are the prototyping work with food-grade materials, while also being resistant to heat conditions, common in the sterilization processes for such materials.
This prototype example was realized in our prototype manufacturing laboratory.
Once the functionality of the prototype was validated, several pre-series units were manufactured to test the product's market acceptance.
Given the positive reception of the new invention, the inventors decided to protect the mechanical system created by our engineers through a Utility Model in Spain.
Invention protected with Utility Model in Spain. Application ES201831231
Case 09. Pizza Cutter
In restaurants specializing in pizza and Italian food, the process of cutting the pizzas before serving is time-intensive and, therefore, resource-intensive in terms of human labor.
Similarly, this process at a domestic level does not always result in perfect portions, which can be aesthetically frustrating for users.
For this reason, the inventors decided to hand this curious challenge over to our product design team.
The mechanical prototype "Pizza Cutter" is a tool designed to optimize and simplify the pizza cutting process, both at the domestic level and in hospitality businesses that offer these products. The prototype allows for quick and precise portioning, cutting perfect slices in seconds.
The challenge at the product design level has been to achieve a mechanical system that truly allows for the fastest possible cut. At the functional prototype manufacturing level, it has been a challenge to work with food-grade materials.
This prototype example is in the commercialization phase.
For restaurant use, the development of an electromechanical machine or cutting robot capable of performing the process more efficiently is not ruled out.
Caso 10. Prototipo ejemplo - Litera triple telescópica
A small hotel management company in Europe, targeting the "low cost" tourism market, found an opportunity to maximize the performance of its rooms.
The addition of more beds in their very low-priced rooms could only be countered by utilizing the height of the rooms.
The directors of this small company conveyed, in the form of an idea accompanied by some sketches, the need to create a triple bunk bed that would also allow for the use of its levels based on the users' needs at any given time.
The prototype had to comply with European regulations governing the bed market, among others related to the use of machinery in domestic environments.
The mechanical prototype: Telescopic Triple Bunk Bed consists of a bunk bed with three levels of height. The levels of the prototype can be managed through a mobile application. The telescopic triple bunk bed features a safety system that prevents the movement of the upper levels when it detects the presence of users on the lower beds.
One of the main challenges of this functional prototype example was obtaining the CE certification, as it was an innovative invention that required very rigorous laboratory testing to verify the safety and ergonomics of the prototype.
The telescopic triple bunk bed is a prototype example that responds to an intrapreneurship initiative. Therefore, the use of these beds is exclusive to their hotels. As far as our team has been able to determine, the hotel has achieved its profitability goals and is soon announcing the launch of a new prototype version: "IOT bunk bed" to bring to market.
Case 11. Salad Bowl with Dressing Filter. Examples of Simple Inventions.
Salad dressing is a homemade and unique sauce for each plate, which in most cases is not consumed entirely, as many of us would like.
The inventor of this product was clear about the need to create a tool that would allow for consuming the sauce without violating table manners or protocols.
The challenge was to create a functional prototype that was also aesthetically pleasing and allowed the user to filter the accompanying sauce of dishes served in it, according to their preferences.
In this prototype example, choosing food-grade materials was a true challenge. While the properties of materials available for food use are common and accessible for injection molding and similar methods, working with materials of these characteristics for prototyping is not that simple.
A simple, ergonomic, and practical design has been achieved to customize the particle sizes that are desired to pass into the dressing reservoir.
Important inventions do not have to be complex and difficult to manufacture solutions. Some examples of simple inventions, such as the salad bowl, represent genuine business opportunities.
The chances of a product's success in the market are not measured by the level of technological complexity, but by its ability to solve a real problem.
After conducting several commercial tests, the inventor has decided to proceed with the necessary investment to mass-produce the product and launch it to the market.
Case 12. Example of Useful Inventions for the Home. Upright Broom.
In most households, it is common to find stains and dirt at the height of broom handles.
The frequent leaning of brooms against the wall continuously deteriorates the aesthetics of the environment, and it is a reality we all live with.
Surely, you have also experienced situations where, during cleaning, you need to carry out other immediate tasks, creating an uncomfortable situation due to not having an appropriate spot to immediately rest the broom.
The inventor's idea, from the very beginning, was to address this challenge with an innovative product that, without using electronic systems, would allow the broom to stand upright without being leaned against other surfaces.
There are examples of easy ideas that have very high chances of success. The broom with vertical stability could be a simple prototype example, although achieving this simplicity has required dozens of hours to create a functional, ergonomic, and innovative design.
The innovative broom has the ability to remain in a vertical position without any additional support other than the one provided by the device itself with its innovative mechanical system.
Challenges of original inventions:
Thinking of less obvious solutions and analyzing their advantages and disadvantages.
Assessing the number of resulting parts required for it to function.
Define prototype manufacturing methods and optimal materials.
Manufacturing initial validation models.
Redesign the invention.
Manufacture a functional prototype of the invention.
The inventor has succeeded in patenting this prototype example.
The inventor has started the patent sale process after having several units of their functional prototype.
Case 13. Electronic Paper Towel Dispenser.
Paper towels have become an essential product in most households. It is a convenient and hygienic solution that has replaced or minimized the use of common dishcloths.
The excessive use of paper towels in many cases is caused by the user avoiding touching the roll to prevent transferring stains onto it.
Seguramente te has encontrado con situaciones en las que desearías obtener el papel por arte de magia, sin necesidad de tirar del rollo y consumir mucho más del papel que realmente necesitas.
This was precisely the challenge shared with us by the entrepreneur, owner of this prototype example, invented, designed, and manufactured in our laboratory.
The electronic paper towel dispenser features a support tray capable of moving sufficiently to allow for the exchange of rolls.
The touch buttons allow customization of features such as lighting color or the amount of paper we want to dispense in each service.
The dispensing service is activated through a proximity sensor, calibrated to detect the hand from 1 cm to 5 cm away. This way, accidental activations of the service have been avoided.
The functional prototype includes a mechanism for retracting the paper, so the prototype is designed to recover any unused paper.
Although the electronic paper towel dispenser could be classified as an electronic prototype example, we have decided to categorize it under mechanical prototypes because the main challenges were more related to mechanical design than to the electronic solutions required for its development.
After the validation of the functional prototype example, the startup promoting this invention has decided to protect its intellectual property through a utility patent in the United States.
The prototype is in the optimization stage to begin the development of mass production.
Case 14. Opening Mechanism for All Types of Containers. Example of Innovative Packaging.
How many times have you tried to extract the last drop from the ketchup bottle?
Does the same happen with shampoo and shower gel?
In our daily lives, we improvise and spend time trying to get that last bit of liquid products, usually dense, that we use regularly.
To solve this problem, we designed a mechanical system that maintains the seal of the containers for these liquids while incorporating an easy-to-use tearing system for the packaging.
Innovation in packaging should not focus solely on design and aesthetics. By observing and analyzing customer behavior, it is possible to design unique packaging that adds value.
The prototype example "liquid container with easy tearing" is applicable to any type of common liquid packaging or container.
The incorporation of this system allows for easy tearing, without the use of any tools, from any liquid container to take full advantage of the product.
The main challenges of the prototype manufacturing process were related to research on production methods that would allow for achieving this tearing function without affecting the strength of the container's walls, while maintaining the same level of sealing.
After the validation of the functional prototype example, the startup promoting this invention has decided to protect its intellectual property through a utility patent in the United States.
The prototype is in the optimization stage to begin the development of mass production.
Examples of Medical Prototypes
Medical prototypes require a high level of specialization, especially because the regulations affecting the development of new medical products are very strict. At Let’s Prototype, we have been bringing healthcare inventions to life for over a decade, ranging from software platforms to physical devices aimed at improving procedures, increasing efficiency in hospital processes, and, of course, enhancing patient safety and care.
Although we do not underestimate the high level of complexity and dedication required to manufacture any invention, the truth is that the medical prototypes developed in our
Our experience working hand in hand with hospital innovation teams, medical research teams, and major distributors of medical products has been instrumental in establishing the foundations, procedures, and ISO quality certifications to position ourselves as the leading invention factory for the healthcare sector in Spain.
Case 01. Nuerobia Research. Prototype for patient rehabilitation.
It is no secret to anyone that stroke is a phenomenon that has become a silent epidemic for our society, 15 million people suffer from it every year. The sequelae of Acquired Brain Injury focus on mobility, language and cognitive abilities. In all cases, the main treatment is rehabilitation.
Another well-known phenomenon is the challenging access to personalized and sufficiently intensive rehabilitation for stroke patients to recover their abilities. For this reason, Let’s Prototype has worked hand in hand with a team of researchers from around the world to create a method based on a mathematical model, as well as products related to the solution Neurobia Research.
Neurobia Research is a platform based on a software solution, as well as a group of sensors and electronic devices designed to bring rehabilitation to patients' homes. It also enables healthcare professionals to monitor the rehabilitation process without requiring doctors or patients to travel.
This example of a medical prototype has involved the development of:
- Mathematical models to digitize the diagnostic process through exercises performed by patients in front of a sensor capable of capturing their movements.
- Calibration of electronic sensors capable of capturing the patient's voice and training them in the process of improving their speech.
- Development of health-focused video games with complexity levels customizable by medical teams.
- Integration of electronic sensors that form the circuit of Neurobia Research devices.
- Development of a telemedicine platform, capable of processing and accumulating patient data for the correct diagnosis by health professionals.
- Design and manufacturing of mechanical products to facilitate the installation of electronic sensors in patients' homes.
- This example of a healthcare prototype has significantly boosted the learning curve of the Let’s Prototype team in terms of software development, Artificial Intelligence, Mathematical Models, 3D design<span
In addition to participating in the design and manufacturing of this medical prototype, the Let’s Prototype team has facilitated, through its private investor network, BusinessInFact S.A, the funding to support part of the prototype development.
See more details about this example of medical prototype based on virtual reality and the development of machine learning models.
Case 02. Container for infectious waste. Medical Prototype -Sustainable
The management of waste with risks of biological contamination poses a significant challenge in medical centers.
The usual procedure in this case is based on the use of yellow containers, made of plastic, which you have probably seen in many hospitals.
By regulation, due to the risk associated with objects such as syringes, needles, and similar items, the waste management container must have a sealing system that prevents full exposure of its contents, as well as a mechanical system that minimizes the risk of exposure in case of accidents.
The current procedure consists of:
- Transporting the containers, once they are full, to the autoclave or sterilization area.
- Breaking the lids of the containers.
- Sterilization of the contents.
- Once the contents are sterilized, they are treated as regular waste.
The challenge proposed by our client was to invent a container with a capacity similar to that of the containers currently in use. Additionally, this container to be “invented” had to comply with current waste management regulations without being made of single-use plastic.
In general, this medical prototype would consist of a container designed for the safe collection of infectious medical waste.
The challenges of this medical prototype example can be summarized as:
- To obtain a cube that would allow the insertion of the infectious content easily and safely.
- Convert the sanitary container into a recyclable prototype, so that it should allow the disinfection of the interior material of the container in an autoclave without deforming the structure of the prototype.
- To achieve a mechanical system that would allow the container to be emptied and secured again, simply and quickly, without sacrificing the safety of traditional containers.
The designed medical prototype consists of a cube-shaped container with an added chimney-like structure that houses an internal mechanical sealing system for the lid.
With a special tool, it is possible to open the lid instead of permanently destroying the seals, as is currently done with commercial containers.
At the same time, the inner chimney of the cube allows the contents to be disinfected under the usual conditions of the autoclave machines already used in this part of the procedure.
The major difference is that the container designed in our product development laboratory allows for 900 uses instead of a single use, like the ones currently in use.
Similarly, the container created at Let’s Prototype features a mechanical system that allows opening and closing using the same handle of the cube, enabling or restricting the entry of infectious risk material.
Invention protected by International Patent: EP4151243A1.
Case 03. Ergonomic device for labor and postpartum processes
Natural exercises and positions before, during, and after childbirth are a true science that directly influences the experience of natural birth.
Currently, the products used to support women in this process include balls, Pilates equipment, and other items that, although proven to be useful, have not been specifically designed to achieve better results during childbirth.
For this reason, our client, together with our industrial design team, has devised a special piece of furniture for the childbirth process. This is a medical prototype example co-created and manufactured in our invention factory in Madrid.
It is a mechanical prototype designed to serve as a support and refuge for childbirth and immediate postpartum exercises. With the use of this patented invention, expectant mothers can regain strength through rest cycles in a strategically positioned manner during the procedure itself. This is an ergonomic prototype with highly specific features for its intended use.
The fundamental challenges of the medical prototype manufacturing process involved the production of large-sized parts using 3D printing and alternative prototyping methods. The prototype had to be both resistant and lightweight while remaining ergonomic, which required a highly intricate industrial design to achieve the functional prototype shown in the images.
After manufacturing the first functional prototype, demonstrating its technical feasibility, and analyzing the economic balance of the product versus the benefits it provides, the decision was made to protect the product's intellectual property.
Patent Number ES1297821U
Case 04. Portable PCR Laboratory. Examples of prototypes from the COVID era.
The COVID situation was a driving force for many inventors and entrepreneurs. They identified a major problem to develop innovative products with a significant social impact worldwide. Although there is much to regret from this period, we must also acknowledge that many examples of innovative products emerged to combat the pandemic.
In our invention factory in Madrid, we support inventors and companies with a strong commitment to developing medical products to enable rapid diagnosis in remote areas or regions far from hospitals.
The portable PCR laboratory was one of the main challenges in our engineering studio in Madrid. We had to develop a portable laboratory that, in addition to enabling COVID diagnosis through commonly known PCR tests, had to be easily transported by medical professionals in hard-to-reach areas.
The main challenges of this prototype example were:
To develop a portable laboratory, based on existing devices but controlled within a proprietary electronics and software environment.
To rapidly develop an online diagnostic system within the laboratory to identify potential errors and results impacted by these behaviors.
Designing a lightweight prototype so that professionals could transport it easily.
Manufacturing a prototype in record time, with optimal conditions to obtain CE certification and be used as quickly as possible.
Design the prototype so that, using prototype manufacturing techniques, it could be easily replicated. Keep in mind that there was neither the time nor resources to industrialize the product.
This is an example of a prototype designed and manufactured in record time. The involvement of component suppliers as well as medical product certification laboratories was more than necessary.
Caso 05. Soporte RX bucal. Inventos médicos originales
Oral X-ray procedures are very common for monitoring dental treatments during their execution. Currently, it is common for patients to have to hold these devices with their fingers for long periods, despite the discomfort and the lack of ergonomics in the diagnosis. For this reason, we supported the inventor in the development of an innovative product, useful as a support for the X-ray equipment used inside the mouth.
Challenges faced in developing this invention example:
- Use of biocompatible materials, as the device remains inside the mouth.
- Use of flexible materials to ensure ergonomics during use.
- Definition of materials that do not interfere with the image samples required for medical procedures
- Design compatibility with various medical equipment heads used for X-ray sample collection.
After the manufacturing of the first functional prototype with biocompatible materials, field tests have been conducted to validate its functionality.
The patent for the invention has now been requested to begin the process of obtaining CE certification.
Case 06. Electronic device for the production of specialized pharmaceuticals.
The production of specialized pharmaceuticals for the development of varicose vein treatments is one of the most pressing needs in non-invasive medical procedures. In collaboration with the network of clinics and the research team at Varycentro, we manufacture high-precision functional prototypes.
The medical prototype example is a specialized mixer where capsules are attached for the production of the medication.
With spins at extremely high revolutions, driven by a custom-designed electromechanical system for this biomedical device, the interior of the capsule generates movement through blades propelled by a magnetic system. This system operates inside the capsules to achieve the perfect mixtures for treatments.
The prototype example features a touch screen resistant to liquids and dust, with IP67 certification, ensuring the reliability of the prototype example.
The design and manufacturing of proprietary, reusable, and therefore sterilizable capsules to avoid single-use plastic products—without compromising the economic viability of the invention—was an even greater challenge than the design and production of the electronic medical prototype.
As a continuation of the project, we manufactured a pre-series of the product, useful for gathering usage data and defining new improvements to the innovative prototype.
Case 07. Foldable stretcher with automatic adjustment
Physiotherapists and patients experience highly uncomfortable moments when posture changes are required during therapy sessions.
In most cases, these posture changes could be achieved by adjusting the geometry of the stretcher itself. However, the rigidity of its parts and the lack of sufficiently resistant electromechanical systems prevent physiotherapists from adjusting the stretchers without requiring the patient to move.
On the other hand, physiotherapists increasingly need to adapt to their patients' schedules, making home service a growing trend.
With these factors in mind, a sufficient requirements analysis was conducted to define the prototype design costs and its subsequent manufacturing.
The stability of the stretcher, the ability to support more than 100 kg of static load, the design of an intuitive interface to control the stretcher's mechanical movements, and the use of lightweight materials without compromising strength to ensure portability were some of the challenges proposed for the development of this medical prototype example with a certain level of mechanical complexity.
Medical prototype examples commonly share a certain level of complexity in the design of their mechanical components. The use of special materials that are biocompatible, hypoallergenic, lightweight, and highly resistant is often a recurring requirement in most biomedical prototypes developed in our laboratory.
In this specific case, meeting the requirements established by the standards for stretchers used for similar purposes, along with the necessary strength due to the very nature of this prototype example, made achieving a foldable yet lightweight system seem contradictory.
The first version of the functional prototype was achieved using techniques such as laser metal cutting, repurposing standard stretcher components for textile design, a custom-designed mechanical portability system, electronic management of linear actuators, and an IoT layer to control the stretcher via a mobile phone. It includes a posture-saving system that can be managed from the device itself, as well as a manual control system with touch buttons, allowing for real-time customized adjustments.
Unfortunately, in this case, the innovation was heavily constrained by a previously registered patent. Registering intellectual property before completing the engineering process often prevents necessary adjustments unless inventors acknowledge the need to withdraw erroneous utility model registrations that lack solid engineering justification.
Examples of IOT prototypes
IoT prototypes (Internet of Things) are technological, physical products that we frequently interact with in various processes. Their unique feature is the ability to collect relevant data and send it to the cloud, allowing us to process it and obtain valuable information remotely.
The proliferation of IoT technology has accelerated the development of prototypes that enable us to gather more information about processes, making them more efficient. Below are some examples of IoT prototypes manufactured in our invention manufacturing laboratory.
Case 01. IOT lamps.
The mobility reduction situation that we all experienced during the pandemic was one of the most significant drivers in the advancement of IOT solutions. In our laboratory dedicated to manufacturing IOT inventions, we developed more than a dozen IOT prototypes during this period. Without a doubt, Luzea was one of the most comprehensive projects of this phase.
Luzea is a solution that allows devotees to pay tribute to their religious icons through candles that can be managed and monitored from a mobile app from any geographical location in the world.
The solution consists of a physical candelabrum, aesthetically compatible with the interior environment of churches, featuring multiple levels of candles with LED technology that simulate natural candles commonly found in these settings.
The prototype manufacturing and the first pre-series units in this prototype example were key, as these were the units that would be presented to the officials responsible for new technology in the major churches of Italy and worldwide.
The candelabrum is an IoT product, as it can be controlled through mobile applications installed on users' phones, both iOS and Android.
From the app, users can select the candelabrum and the church where they want to light their candle, complete the payment process based on the desired lighting duration, and, once the process is completed, view the lit candles through a real-time video stream from the same mobile application that controls the IoT prototype example.
In a significant number of churches, including some in the Vatican, physical candelabra have been installed, maintaining a special connection with the characteristic interior design of churches. From the mobile app, users can light the candles and view them in real-time from any geographical location.
Currently, there are dozens of IoT candelabra installed in churches worldwide, and thousands of users utilize this technology in the practice of their faith.
The invention is not patented, as, although it is an innovative IoT solution, the decision of the team of inventors and company managers has been to accelerate the product's commercialization process.
Case 02. Corner Flag with Camera. Examples of Prototypes.
The participation of fans in sporting events is becoming increasingly immersive. There are numerous technological initiatives and new inventions aimed at making fans an active part of these events.
Similarly, the demands of users watching from home through television broadcasts continue to grow as new technologies are incorporated into sports venues.
Prototypes of drones for continuous sports action broadcasting with tracking systems, the development of artificial intelligence engines and intelligent image processing to share real-time content with television viewers, are some of the examples of sports prototypes that, in recent years, have aimed to enhance the coverage of sporting events.
In this example of innovation, the objective was to capture the moment of a corner kick, as it is known in the world of football. The promoters aimed to perfectly capture both the image and sound of this type of action as it unfolds.
In order to achieve increasingly immersive sports broadcasts for viewers, an invention has been developed whose objective or challenge was to include a system of manageable cameras in the corner post itself so well known in football matches.
The IoT prototype described has been a mechanical, electronic, and telecommunications challenge. The camera system embedded in the corner flag offers a unique perspective in the broadcasts of this highly popular sport in terms of audience numbers.
This example of a prototype faced mechanical challenges, as commercial camera stabilizers were not designed to be inserted inside the post used on football fields. The dimensions of these posts are regulated, making it impossible to alter their size and geometry to accommodate the necessary technology.
Size restrictions often add an extra layer of complexity to the design of prototype examples like this one.
On the other hand, this example of an innovative product for sports had to be compatible with IoT technologies while also featuring a wired image transmission version.
The first prototype of the football post was installed in several fields to test its functionalities in real environments.
The product's waterproofing, due to its need to withstand adverse conditions, and the management of the mechanical components through IoT mobile applications were key aspects in the product's concept testing.
Currently, the prototype example for football fields has been tested in official matches with highly promising results.

Invention with International Patent: WO 2016/181000 A1
Case 04. Humidor humidity control device
Not all new inventions and examples of technological prototypes need to include more features than their predecessors on the market. In fact, a common mistake among many inventors is attempting to add extra features for differentiation that are ultimately not valued by customers.
Simplifying technological products presents a clear business opportunity, allowing for fair pricing and the creation of simple products that meet users' exact needs.
In this example of an IoT prototype, the goal is to maintain simplified control over the storage cellars for Cuban cigars. Due to the nature of cigars, it is critical to keep the environment at a relative humidity of 70% to preserve them over time.
Excess humidity causes swelling inside the cigar, preventing proper enjoyment, while storing it at a lower relative humidity also renders the product unusable.
There are some IoT electronic products that communicate with mobile apps and operate very efficiently. These modules consist of sensors that measure the temperature and relative humidity of the environment. These sensors continuously send alerts when the configured storage ranges are exceeded, while also allowing users to check the status of these environments from anywhere at any time.
However, using mobile applications to control this example of an IoT device introduces a set of component requirements that increase the production and sales costs of the prototype example.
For example, the high communication demands require the use of more expensive rechargeable batteries with charge management circuits, adding unnecessary costs to the product.
After a preliminary market analysis, we discovered that users only want to be informed when there is a risk in the storage environment. They do not need to check conditions sporadically, receive unnecessary notifications, update mobile applications, or worry about continuously charging the batteries.
The general objective for the innovation process and the creation of the new prototype was to simplify existing products and develop a prototype example that solely fulfills its primary function: alerting in risk situations without bothering the user or requiring any management.
This example of a prototype with IoT technology clearly demonstrates that competitive advantages can be achieved through simplification.
The humidity control device for humidors, featuring IoT technology, is an example of a prototype whose innovation is based on simplifying alternative prototypes and previous market solutions.
The prototype is a small, thin, circular device. Its size and shape are designed to avoid interfering with the capacity of cigar cellars or humidors commonly available on the market.
The IoT firmware is capable of maintaining long periods of deep sleep for the electronic components. This has made it possible to eliminate charging circuits, charging ports, and the high costs of rechargeable batteries. Instead, this example of a PCB integrates a widely available commercial battery that is easily replaceable.
The device performs checks every 24 hours and, without needing to connect to any other device or mobile application, determines whether the relative humidity and storage parameters are within the appropriate range. In case of an alert situation, the device sends an SMS to the user to notify them of the issue.
The IoT device Humidor Controller is now a reality. Simplifying functions that are not valued by customers has had a significant impact on the manufacturing cost of the units. This cost reduction has allowed this example of a prototype to be marketed directly to humidor manufacturers (storage boxes) or cigar manufacturers, who use the IoT prototype example as a promotional complement to enhance the value proposition of their products.
Case 05. IoT security device for hikers.
The sports industry has been one of the biggest beneficiaries of the development of IoT technologies and the rapid implementation of machine learning models. At Let’s Prototype, we have contributed to the development of prototype examples that have permanently transformed safety and technique improvement in many sports, working hand in hand with entrepreneurs who have in-depth knowledge of on-field enhancement opportunities.
In this example of an electronic prototype with artificial intelligence models, the objective was to design a safety system for people who practice hiking.
At times, hikers, whether individually or in groups, risk getting lost or experiencing accidental falls in areas that are difficult to locate and access.
The goal of the team of entrepreneurs was to integrate this electronic system with IoT technology and a mathematical model to identify risk situations into a design very similar to that of a walking stick, without compromising its visual aesthetics or durability.
The Smart to Walk prototype example presents challenges in firmware programming and embedded systems with machine learning models, touchscreen management, and custom PCB design, requiring the use of commercial controllers to enable the deployment of IoT solutions.
Smart to Walk is the first smart cane on the market, capable of detecting risk situations, identifying accidents, and efficiently communicating these incidents to emergency services and user-designated contacts.
To maintain the ergonomics of traditional hiking canes, lightweight materials were used without compromising the durability of these devices. The electronics required for the smart functionality of this IoT prototype example were concentrated in a unique design within the handle area, allowing the device to be used without altering its natural shape.
The designed PCB for this prototype example includes inertial sensors, gyroscopes, and accelerometers that enable the identification of movement coordinates. Additionally, the custom-designed electronics feature connectivity capabilities to send alert notifications to contacts selected by the hiker.
It is important to highlight that this IoT prototype example with its own machine learning models follows a logical format based on Edge Computing protocols. Edge computing prototype examples are electronic devices capable of analyzing data directly on the device itself, without requiring cloud connectivity to make decisions or identify alert situations. This edge computing device example eliminates the high energy consumption associated with cloud connectivity, which is why the intelligence layer has been integrated into the same physical prototype. As a result, it only transmits communications when a real alert situation occurs.
In addition to the alert system managed through IoT communication protocols, this prototype example features an audible and visual alert system, allowing nearby individuals to provide immediate assistance.
In addition to the hardware prototype, it was necessary to develop an IoT control app. This app allows users to select emergency contacts and predefine message templates that will be sent based on specific conditions if the smart cane detects dangerous events.
Smart to Walk is a startup that is already in the market. The first prototype examples were used to conduct calibration tests for the event detection algorithm and alert system in real hiking environments.
Case 06. Let’s Device - Wearable Prototype
Many inventors aim to develop smart bracelets similar to market smartwatches with innovative features.
Most of these bracelets must be equipped with inertial sensors, heart rate monitors, touchscreens, and, as a common challenge, aim to develop innovative features while optimizing energy consumption to achieve maximum autonomy.
For this reason, at Let’s Prototype, we have decided to develop our own bracelet with all these features, enabling the creation of functional prototype examples in a much faster and more cost-effective way than a fully custom technological development.
For example, we have used this wearable device example to perform measurements and subsequently train artificial intelligence models, which have been applied in sports such as sport fishing, padel, golf, and baseball.
If you need a minimum viable product that can identify movements, connect with IoT mobile applications, and interpret biomechanical movement results—adding significant value for continuous improvement in sports—we will be much closer to completing the first functional prototype example with the appearance of a final product.
We now have our own custom wearable device. Our Let’s Wearable bracelet includes a wide range of capabilities, and best of all, we can adapt it to your project in record time.
Our Let’s Wearable includes GPS, Accelerometer, Gyroscope, Heart Rate Monitor, Radio, Microphone, Speaker, among other features that allow us to develop your prototype more efficiently and accurately than any competitor.
The Let’s Wearable has been tested with mathematical models for various sports, and in all cases, it has demonstrated a high level of operational stability.
Our wearable device example has been used for the development of themed bracelets with highly specific applications. A common factor is its use in projects requiring the ability to identify and compare executed movements with pre-recorded model movements.
This prototype example enables the faster and more cost-effective development of functional prototypes, as we have full control over its components. This allows us to adapt the bracelet to any use requiring all or some of the electronic components integrated into its central PCB.
Among the applications of this functional prototype example, the following stand out:
Smart Watch for Padel: It identifies, in real-time, the different types of strokes executed by users. During a padel match, the bracelet can distinguish between 14 common stroke types in this sport while sending data to an IoT mobile application. This information is used to generate insightful graphs that allow users to analyze and study their playing styles, effectiveness, and even compare their movements with those of professional players who contributed to training the machine learning models integrated into the control firmware of the Let’s Wearable bracelet.
Smart Bracelet for Golf: In this prototype example, the Let’s Wearable smart bracelet has been used to train a machine learning model example capable of recognizing key parameters that define different types of golf swings. The bracelet has been trained by professional players, allowing it to identify when a technique has been executed correctly and to list the errors made by users.
Smart Bracelet for Fishing: In this specific case, the bracelet functions as an electronic prototype that receives signals from a third sensor installed on the fishing rod. Using a machine learning model, it can detect effective fish bites. When these events are identified, the smart bracelet triggers an alert, allowing the user to classify the event through its AMOLED touchscreen. This process not only enhances the experience of sport fishing but also enables the artificial intelligence model to continuously learn from the data provided by fishermen using our smart bracelet.
Smart Bracelet for Baseball: Our bracelet has been trained by high-performance baseball athletes. Through this training, it has been able to classify data associated with different swing techniques, allowing users to instantly compare their practices with the recorded models of professional athletes. In this functional prototype example, the bracelet transmits data to a mobile application, where comparative graphs are displayed to help plan targeted training sessions for improving performance in the sport.
Case 07. IoT Device Baliz-E Road Safety for Cyclists
Cyclists remain vulnerable on public roads. Numerous accidents have been recorded in which they become victims of collisions with motor vehicles that fail to receive early warnings about potential risk situations.
Considering this problematic scenario, the client inventor proposed the use of an electronic device equipped with a machine learning model capable of detecting accident situations and transmitting an alert signal to other devices that motor vehicle drivers should carry.
For the development of the first functional prototype, the communication between the device detecting falls had to be capable of transmitting an alert up to 1KM away. This way, vehicles equipped with a receiver device could efficiently process the alert before approaching accident events or hazardous situations.
As a unique feature of this IoT prototype example, the receiver devices also needed to function as electronic signal-emitting devices, ensuring that the alert could be relayed beyond the initial 1KM range considered for communication between the prototype installed on bicycles and the signal-receiving prototype in nearby vehicles.
Baliz-E is a system of IoT devices designed to enhance cyclist safety on the road. The devices installed on bicycles can detect accidents or hazardous situations and transmit alerts to motor vehicles approaching the accident site.
As a unique feature, the electronic receiver devices installed in motor vehicles automatically become signal-emitting devices upon receiving accident alerts. By leveraging the Baliz-E device network, a wide alert system is created, significantly enhancing the safety of the injured cyclist.
Baliz-E was one of the first prototypes developed and manufactured in our innovation lab. It is currently registered as a patented invention: ES1226089Y.
This functional prototype example was a finalist in competitions organized by companies in the automotive insurance sector in Europe and is currently in negotiations for the democratization of the product in the market.
Case 08. IoT Device Examples - Smart Shelves
The planning of the product restocking process in supermarkets is a real challenge for workers, as well as a critical point for manufacturers of products sold on these platforms. This necessary balance has driven the development of an IoT prototype consisting of a smart shelf system capable of detecting when a product is running low on display, while sending the corresponding alerts and forming an intelligent restocking plan.
The challenge of this IoT prototype example has gone beyond the mechanical area, where metallic prototypes with food-grade specifications were required, as well as a telecommunications structure sufficient to ensure the proper transmission of alert signals.
This functional prototype example has been tested in various supermarket chains. The smart shelf prototype allows for the identification of products on display that are running low, and with the help of planning software, it is possible to create much more organized restocking routes, ensuring compliance with supermarket display contracts for brands that manage their products through these sales channels.
Case 09. Machine Learning Prototype for Sports. Baseball Analytics
Baseball Analytics is a smart bracelet, developed entirely to quantitatively analyze the batting techniques of baseball athletes. For many years, these techniques have been trained by relying on the experience of coaches and human observation or technological devices. Batting mechanics analysis labs tend to be very expensive, difficult to install, and even harder to maintain over time. Additionally, not all baseball coaches are prepared to work with this technology.⬤
In Let’s Prototype, we have developed a functional prototype consisting of a wearable with an integrated machine learning system, capable of comparing athletes' movements with a fully perfected motion pattern. This immediate quantitative comparison system provides value to coaches and athletes quickly and effectively. The sports world is being completely transformed with IoT prototypes and machine learning products, allowing greater focus on the areas of improvement that have the most impact on an athlete's career.
This functional prototype example is currently in the market testing phase.
Case 10. Easy-open cap for wine bottles with IoT system. IoT prototyping.
Opening wine bottles remains a slow and unergonomic process. It is true that, in many cases, opening a bottle of wine represents a ritual or unique experience, where any innovation may face rejection.
In this prototyping example, the focus was placed on commonly used wine bottles. These bottles are often not consumed in a single day and therefore need to be resealed. This very need gave rise to the initiative of designing an easy-open wine stopper.
On the other hand, most wine producers share a common frustration: the lack of knowledge about what happens to their wine in the market and some post-factory processes. To address this issue, an electronic system with IoT capabilities has been integrated into the stopper itself, allowing the monitoring of key information about the end user's experience with the wine and potential improvements in logistics and storage processes.
The functional prototype developed focuses its innovation on the mechanical opening system, as well as the ability to store critical data for the analysis of wine bottle transportation.
The information stored and managed through this IoT prototyping example allows manufacturers to analyze the impact of the logistics process on the resulting wine quality. Similarly, the use of the prototype has led to a new way of opening wine bottles, utilizing an innovative mechanical system that eliminates the need for additional tools for opening.
After the manufacturing of this functional prototype example, a patent registration has been filed to ensure international protection of the invention. The prototype is being presented to several distributors and manufacturers, with ongoing negotiations for the implementation of a commercial exploitation business model for the patent.

Case 01. Kumby's - Electronic headphones for winter.
While it is true that Bluetooth headset technology is widely available and has been well-received, using such devices in harsh winter conditions can be challenging, as it requires additional cold-weather accessories like earmuffs.
Precisely, Kumbys is an example of an electronic prototype with evolutionary innovation, as it enhances earmuffs, traditionally seen as a winter accessory, and Bluetooth headphones with their corresponding functions, creating a technological prototype that integrates the best functional features of each product.
The Kumbys electronic prototype, designed and manufactured in the rapid prototyping labs of Let’s Prototype, is a headset that simultaneously covers the ears from the cold in winter conditions.
Thanks to the minimalist design of the product achieved by the industrial design team of Let's Prototype, the product has obtained two titles of Utility Model in the Spanish Patent and Trademark Office.

Case 02. Fuel flowmeter
Surely, at some point, you've suspected that your car may have consumed less fuel than what is indicated by the fuel dispenser station. In response to this recurring suspicion, the team of inventors has proposed and patented a prototype consisting of a portable flowmeter that can be kept in the glove compartment of any vehicle and is capable of adapting to any service nozzle.
The prototype has the ability to display the actual amount of fuel dispensed into the vehicle on a screen, allowing drivers to verify the exact quantity of fuel provided.
This prototype example includes an IoT layer, as the fuel flowmeter is capable of connecting to an app where it stores records of dispensing cycles. In this way, users maintain a much more controlled historical record.
Among the main challenges of this prototype example is the need for the device to be compatible with different types of dispensing pumps, as gasoline and diesel have different geometries.
After conducting functional tests on the IoT prototype, the team of inventors behind the technological project decided to register the invention as a patent in Spain.
Invention protected with International Patent. No. WO2022/129671A1
Case 03. Shower Massager Device
Over the years, for practical reasons, space optimization, and also due to the reduced time available in daily life, the habit of taking baths has been replaced by shower processes. These are much quicker but also reduce the quality and relaxation capacity of traditional baths.
Considering these premises, the team of promoters has evaluated the possibility of creating an invention capable of improving the quality and relaxation capacity of a shower, by applying massages with an electronic device that has the ability to exfoliate the skin while delivering massages that move along the body.
The prototype consists of an innovative electromechanical device, capable of applying customized massages on the back while dispensing shower gels during the shower process. Through a remote control, the user can adjust the rotation speed of the sponges, the amount of gel to apply, as well as the direction in which the sponges perform the massage and the paths of the electromechanical prototype.
All electronic prototypes capable of handling liquids require an advanced level of industrial design as well as the study of optimal materials for prototype manufacturing, which must then find analogies with other materials for industrial or mass production.
After an intense cycle of experimentation and testing with the functional prototype, improvements have been made related to the mechanical design and electronic design of the device.
The product is currently in the mass production stage, with the aim of initiating the commercialization process through a cabin construction company for hotel operations in the rural tourism sector.
Case 04. Well of optical illusion
The goal of the invention was to create a prototype capable of generating an optical illusion that simulated the existence of a deep well. The prototype example was designed for incorporation into an optical illusion museum, so one of the main challenges was related to its mechanical strength, as users would stand on the prototype example.
Functional prototype of an optical illusion, where the simulation of an infinite well has been achieved, although in reality, it does not exceed 10 cm from ground level. The prototyping process was very creative and fun. Currently, the optical illusion well prototype is used in leading optical illusion museums in the market.
After subjecting the first prototype to real tests in an optical illusion museum in Toledo, Spain, several units have been manufactured for commercial exploitation in various themed museums across Europe.
As a substantial improvement over the technology created for the first functional prototype, the inclusion of an electronic solution that allows control of the prototype via a mobile application stands out. Through this IoT application, it is possible to remotely turn the well lights on and off, as well as adjust the lighting intensity, creating an effect of varying perceived depth levels in the manufactured prototype example.
Case 05. Smart mop with dispenser and interchangeable head.
Cleaning processes on commercial or household surfaces are often intensive in time and effort. Rinsing and wringing cycles, as well as the application of cleaning products, improve cleaning quality but extend the time needed to achieve optimal results.
This prototype example consists of an electronic mop, designed to minimize the force needed for rotational movements during the cleaning cycle. Likewise, the motor system enables more consistent movements, which in turn improves the overall cleaning cycle.
This product includes a reservoir and an electromechanical dispensing system that applies cleaning liquids onto the treated surface.
Both the dispensing system and the movement of the mop heads can be adjusted according to the user’s needs. This was achieved through an iteration and calibration cycle that was part of the product development process.
As an additional innovation in this prototype product example, the mop heads can be swapped out without needing to touch wet or dirty surfaces.
The interchangeable heads represented a significant innovation, allowing the mop to be effective on various types of surfaces. This maximizes the versatility and usability of this cleaning machine prototype for surface maintenance.
The functional prototype example of the smart electronic mop has been validated by the client. It is currently in the process of industrialization and mass production for subsequent commercialization through online sales channels.
Case 06. Domestic-use machine for squeezing lemons. Electromechanical prototype.
Lemon juice is a high-demand product in cooking and mixology. Squeezing the juice from lemons can be a very complex task when large quantities of juice are needed. It is a manual process that is time-consuming and physically demanding.
The invention developed in our laboratory faced the following challenges:
Design a mechanism robust enough to squeeze at least 6 lemon halves at the same time.
Design a compact machine whose height does not exceed the dimensions of common technological products typically used in a kitchen.
The machine was required to have a portable reservoir to facilitate the removal of the juice.
The user interface needed to include a digital touch screen, allowing users to customize the squeezing intensity for the lemon halves.
Achieve an ergonomic design for the exchange of the squeezing tray, as well as ensure the overall ergonomics of the machine.
Achieve a design that allows the machine to be portable, enabling users to transport it anywhere.
Manufacture a prototype using heat-resistant plastic materials, ensuring the squeezing tray can be cleaned in a commercial dishwasher.
The prototype, in addition to featuring an exclusive and minimalist design with carefully crafted curves to maintain its aesthetics, required a technical validation cycle to calibrate the squeezing customization system.
The mechanism of the lemon juice machine currently has a registered patent in the United States.

The prototype features a fruit tank, with an inlet equipped with an electromechanical system capable of identifying and distinguishing fruits from unwanted solid waste, so that it can decant only the fruits into the tank carried by the farmer.
The electromechanical prototype has been a significant challenge, especially in terms of ergonomic design, as achieving an ergonomic prototype in this case was almost as important as achieving the key functions of the prototype.
Case 04. Smart Observation Device
The IoT prototype consists of a modular system that integrates: two electronic elements and a mobile application. The first electronic device contains an algorithm and sufficient components to identify color changes at specific points on the plants. Once identified, the farmer receives a notification on the app designed specifically for this IoT prototype, alerting them to the risk situation in the crop. Subsequently, the farmer can take corrective actions directly from the mobile application without having to go to the field. The corrective actions typically involve adding specific nutrients, very precisely, to the water tank used for irrigation systems.
In this example of an invention for agriculture, the experience in mathematical model development, as well as the specialization in the design and development of innovative IoT products, has been key to identifying color change patterns in plants and achieving not only diagnosis through the IoT prototype, but also the corrective measures.

Examples of Software Prototypes
Web Prototypes | App Prototypes
In our design and product development laboratory, it's true that 90% of prototypes have a fundamental component of electronics, design, and telecommunications. This trend of IOT prototypes, robots, and electronic prototypes has required us to include in our invention factory a team of developers for both high-level software and low-level software.
Low-level software: Low-level software is software whose main function is to manage hardware components and usually runs directly on the hardware itself. For example, the software installed in the "brain" of the mobile cleaning robot is responsible for controlling its electronic components. All firmware development can be considered low-level software.
High-level software: High-level software is designed and configured to be used by users. For this reason, design, UX principles, are so relevant in high-level software. Web prototypes and mobile application prototypes can be categorized as high-level software.
Here are some examples of prototypes where the development of high-level software was required. In other words, web prototypes and application prototypes. On the other hand, 100% of the prototypes featured on this prototype examples page, in the categories: IOT Prototypes, Electronic Prototypes, and similar, have required low-level programming to achieve their corresponding functions.

Case 02. App for Agriculture | AI Prototype Examples
The development of IoT products for agriculture combined with AI solutions is proving essential for maximizing crop yields and minimizing farmers' efforts.
In this custom app development example, it has been possible to manage electronic devices capable of measuring water quality, temperature, and the quantity available for irrigation systems.
With this prototype, the inventors have already provided significant value to their clients. However, this is only the first step in the prototype development.
The use of the prototype is continuously feeding a database that combines data such as: climatic conditions, pest development, crop yield, and growth rate. Considering these parameters, along with water data stored and sent from the electronic prototype itself, an AI prototype is being developed to predict types of pests for each crop, based on the conditions to which the crops are exposed at any given time. This way, farmers can make better, timely decisions to prevent damage to their crops.

Examples of Sex Toy Prototypes
Sex Toy Prototypes | Sex Toy Development
The development of innovative sex toys is a rapidly growing industry. At our invention factory in Madrid, we have undertaken several projects related to this sector, especially because sex toy prototype development involves highly complex challenges, such as:
- Biocompatible materials are typically used for those product design components that interact with intimate areas.
- Hypoallergenic materials are frequently used throughout almost the entire structure of this type of prototype.
- When electronic elements or IoT layers are involved, regulations are very restrictive for this type of product.
The complexity associated with the development of sex toy products can be comparable to the complexity involved in the development of medical products. This is due both to the high regulatory standards and to the challenges of creating a prototype that meets functional requirements, taking into account the usual limitations in prototyping processes.
Case 01. Electronic Device for Exercising the Male Organ.
The product development in this sex toy example has involved significant challenges in terms of prototype manufacturing and electronic system encapsulation.
This is a robot prototype capable of attaching to male intimate areas, creating a vacuum environment, and performing exercise movements on the male organ through a system of perfectly coordinated motors.
Among the main challenges in developing the first prototype, we identified:
Study of materials compatible with the solution. Engineering study focused on defining optimal materials for the solution, which also needed to be available through the prototyping resources at our Invention Factory in Madrid.
The machine includes a telescopic adjustment system along different axes, with a mechanical surface adhesion mechanism capable of supporting coordinated movements to achieve the prototype's objectives.

Examples of energy generation prototypes.
Inventors with innovative ideas for generating energy or prototypes aimed at achieving more efficient energy use face some common challenges:
- Demonstrating, in a quantitative and scientific manner, that the idea works.
- Patent the product before starting commercial operations for fundraising.
- Manufacture a functional prototype that leaves no room for doubt and maximizes business opportunities.
Manufacturing a product prototype in this sector is expensive and time-intensive. This barrier is almost insurmountable for most entrepreneurs, who end up shelving most ideas and patents.
At Let’s Prototype, we work hand in hand with inventors to scientifically demonstrate the viability of their inventions, which is ultimately the milestone that alleviates the main obstacles mentioned above.
The great challenge in developing innovative products for energy generation lies in proving that we can obtain more energy with a specific method and product than the amount required to generate it. This energy benefit must also make economic sense. In other words, it is crucial to demonstrate that the investment cost to obtain the energy is lower than the selling price of the generated energy. Using scientific tools that provide concrete data across various performance scenarios, we can prove the technical feasibility of an invention or, alternatively, identify the technical limitations that may constrain it.
Motorized Skylights. IoT Solar Tube Prototypes.
Motorized skylights or motorized solar tubes are devices that allow the use of natural light to illuminate interiors, avoiding unnecessary electricity consumption during times when it is not needed.
Although solar skylights are old inventions that were already used in industrial buildings during the Industrial Revolution, the truth is that innovation in this type of invention for harnessing solar energy has not changed much.
Motorized skylights feature a mechanical system with a circular structure, precisely designed to fit its edges onto a counterform inside the solar tubes. This design maximizes their ability to efficiently allow or block the entry of light.
This motorized system, anchored inside the skylights, is controlled by a stepper motor, allowing a wide range of natural light regulation inside a space.
The proposed electromechanical system allows for its inclusion in any type of standard skylight available on the market. This enables installers and users to integrate it as a module to enhance the performance of their installed skylights.
Examples of Kickstarter Prototypes
Financial resources are a barrier for many inventors with great ideas. The product development cycle is often a process that demands significant time and financial investment.
Many of our clients are individual inventors or small startups, so finding alternatives to launch their products to the market is a top priority.
Publishing product prototypes on Kickstarter is one of the most commonly used tools by inventors in the early stages. Although rapid prototyping also requires investment, it allows inventors to raise funds to develop their inventions and establish an initial connection with the market.

Case 01. Retractable Charger – Example of a Prototype Funded on Kickstarter
Today, electronic devices, especially mobile phones, have become an extension of our body and mind. The constant need for charging requires us to have as many cables, and of as many types, as the devices we own at home. The clutter of these cables can be very inconvenient.
The retractable mobile charger is an invention that seems easy to create at first glance. However, the industrial design of a proprietary retractable system to achieve a high-quality effect has required several hours of product development.
The greatest pride of our prototype factory in Madrid is seeing functional prototypes turned into products available on Amazon or other sales platforms.
The functional prototype example has been industrialized and is available on major online sales platforms.
The inventor has presented his product on Crowdfunding platforms and with the funding obtained, has brought his product to stores and distribution channels in Europe and the United States.
This example of a prototype funded on Kickstarter raised over €30,000, reaching 1,634% of the funding needed to meet the goals proposed on the platform.
Case 02. Mobile Remote Control Prototype Funded on Kickstarter
Most of us use audio and video playback devices while showering. Surely, more than once, your phone has ended up submerged — and in the worst cases, seriously damaged.
Based on these precedents, the inventor approached our lab to design and develop a prototype to publish on Kickstarter and launch a fundraising campaign to industrialize the prototype.
The challenge of this prototype focused on two main aspects:
Creating examples of 3D-printed prototypes capable of withstanding shower water. These prototypes would also be sent to the Kickstarter backers as a reward for their support and trust in the product.
On the other hand, although it’s easy to connect peripherals via Bluetooth from any mobile device, in this case, the prototype example of the product had to be capable of connecting to a peripheral to transfer control to it. That’s a completely different challenge.
This last challenge required development on the firmware, or control software of the prototype. In the end, a functional prototype example suitable for Kickstarter was successfully achieved.
The functional prototype example — a device for controlling mobile phones from the shower, without risk of water penetration — was successfully delivered to the client.
Fortunately, this prototype example manufactured at Let’s Prototype secured funding through a crowdfunding campaign for new inventions on Kickstarter.
More than €10,000 contributed by Kickstarter backers, reaching 105% of the funding required by the inventor to take the prototype to the next level.
Case 03. Baby Presence Detection System in Vehicles – Example of Prototypes Published on Kickstarter
To detect the presence of babies in car seats, stickers or static light-up signs are usually used. While it's true that these products can be visible — and some even include LED lights — there is no product that actually indicates when a baby is occupying the back seat of a vehicle. For this reason, the inventors of Babyled decided to design, develop, and patent this solution.
The prototype consists of a sensor placed underneath the baby’s car seat. This sensor can be calibrated through a mobile app using the weight of the seat itself. In this way, when the baby’s weight is added, the smart sensor is able to detect the presence of the baby in their special seat.
This system, which can be integrated into baby car seats, communicates with a light-up triangle that not only alerts other drivers to the possible presence of a baby—like other products on the market—but also confirms with certainty that a baby is occupying the back seat of the vehicle.
In addition to securing a patent capable of protecting the invention internationally, especially in Spain, where the inventors are from, the functional prototype was presented on Kickstarter to raise funds for the development of the product. It has currently reached about 10% of its funding goal.

Example of a solar tube prototype with ventilation and adjustable lighting.
Solar tubes with adjustable lighting are an example of a prototype that provides a modular solution compatible with the best skylights on the market. Through an electromechanical system, it can precisely adjust the entry of light.
While the motorized skylights prototype allows for multiple configuration angles, the single window inside the motorized solar tubes features a mechanical system. This skylight prototype enables the deployment or retraction of interconnected components, allowing for highly controlled light entry, customizable remotely through adjustable channels.
Both this product prototype example and the previous one are designed as installable modules for traditional skylights, equipping these inventions with a motorized electromechanical system that can also be customized to a greater or lesser extent remotely.

Smart skylights for industrial buildings. IoT solar tubes.
Industrial buildings and facilities are frequent beneficiaries of traditional skylights. In these types of installations, precise light configuration is essential, as it has a direct impact on productivity and even on the behavior of certain animals.
In this prototype example of an IoT solar tube, various technologies have been combined to achieve intelligent and automated light management.
IoT solar tubes work in combination with a set of photometric sensors inside the facilities. These sensors can determine the level of brightness provided through the solar skylights. The skylights themselves are equipped with artificial lights, whose intensity is automatically adjusted based on the needs detected by the sensors inside.
Smart skylights combine interior brightness data with preconfigured requirements to adjust the artificial lights inside accordingly. Using an app that controls the smart skylight system, it is possible to schedule interior brightness levels based on time slots. This way, the system prioritizes the use of natural light while ensuring that the illumination levels inside industrial or poultry facilities remain exactly as preconfigured in the app.

Energy Generation System. Ecological Water.
Ecological Water is a energy generation prototype that harnesses existing fluid flows. This invention example involves the installation of a system of blades with a highly specific geometry, designed to maximize rotation inside pipelines. It takes advantage of the momentum of greywater from multiple buildings to generate and store energy.
The work of the mathematics team and engineers at Let’s Prototype involved generating multiple operating scenarios, considering different pipeline diameters, various blade geometries, and other components used, in order to simulate the behavior of the future prototype before proceeding with its construction.
The results obtained substantially transformed the solution compared to the inventor's initial idea. This is why investments in patents should not be made before achieving a scientifically validated and optimized understanding of a product's functionality.

Device for Electricity Generation in Electric Vehicles
There have been numerous attempts at developing innovative products for energy generation by harnessing vehicle motion. In this case, the technical study commissioned by our client aimed to gather data on the potential for energy generation using a system of blades and turbines, which would be activated by the wind hitting the front of the vehicles during braking. This design ensured that no additional drag was created when the objective was to maintain or increase travel speed.
For the validation of this technical study for product development, scenarios were designed and tested in laboratory programs, where it was possible to determine the most suitable geometries and materials for the collection blades, activation systems for startup, and the design of the collection circuit. With these variables, the actual energy generation capacity of this proposal was determined, along with the related economic data.
