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. Step without leg to attach in 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.

Case 02. Bag with umbrella

The bag is one of the fashion accessories most appreciated by women. In rainy situations, carrying it, covering from the rain and without doubt, manipulating the mobile, are actions that are carried out simultaneously.

The invention consists of a bag that includes a mechanical system of portability and deployment of an umbrella that allows to unify the bag and the umbrella in the same product.

During the process of industrial design and manufacture of the prototype, maintaining the balance between the functionality of the prototype and the necessary aesthetics, being a fashion accessory, has been a great challenge.

Case 03. Ladder with legs to integrate into furniture of houses and offices

In order to facilitate access to aerial furniture in kitchens and other environments of homes and offices, a functional prototype has been developed whose fundamental requirements were to achieve a system of steps that could be folded or deployed with two steps and mechanical movements that did not involve a great effort to users. Getting the prototype to be stored in a drawer with a height of less than 10 cm was a real challenge.

Both the identification of regulations that affect the prototype, and the study of the standards to obtain a checklist that will affect the design of a functional prototype that also complies with the standards, has represented a real challenge.

In the design process of the prototype, the analysis of materials, structure and all the necessary details were taken into account to achieve a robust yet aesthetic prototype.

Case 06. Pacifier with Vertical Drop.

Currently, in general, pacifiers are designed in a way that allows babies to suck or suck the nipple, in addition to being perfectly coupled over a baby's mouth. However, it happens that when a pacifier falls to the floor, the teat is in contact with the ground, so it is necessary to wash and even sterilize it to protect babies from possible infections. On the other hand, in general, they do not have the means to protect the teat or hide it when it is not in use, in addition to lacking means that allow a quick location of it even during the night.

The object of the present invention is to overcome the drawbacks pointed out, above all, the contact of the teat with the ground. In Let's Prototype we have designed a functional prototype that avoids the contact of the teat with the ground, regardless of the height from which the pacifier falls.

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 phenomenon more than known to all, is the difficult access to personalized rehabilitation and with sufficient intensity so that stroke patients can recover their abilities. For this reason, Let's Prototype has worked hand in hand with a team of researchers from around the world in the creation of a method, based on a mathematical model, as well as products related to the Neurobia Research solution.

Neurobia Research is a platform based on a software solution, as well as a group of sensors and electronic devices that aim to bring rehabilitation to the patients' homes, also allowing the monitoring of the rehabilitation process by professionals in the health sector, without doctors or patients having to travel.

The present 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 the movements of the individual.
  • Calibration of electronic sensors capable of capturing the patient's voice and training them in the process of improving their language.
  • Development of video games for health with customizable levels of complexity by medical teams.
  • Integration of electronic sensors that make up the Neurobia Research device circuit.
  • Development of a telemedicine platform, capable of processing and accumulating patient data for the correct diagnosis by health professionals.

Examples of IOT prototypes

IOT (Internet of Things) prototypes are technological, physical products with which we usually interact in different processes and, as a singular feature, they allow the collection of relevant data and send them to the cloud so that we can later process them and obtain relevant information remotely.

The proliferation of IOT technology has accelerated the development of prototypes that make us obtain more information from the processes and therefore, be more efficient. Here are some examples of IOT prototypes manufactured in our invention manufacturing lab.

Case 01. IOT lamps.

The situation of reduced mobility that we all suffered in the pandemic stage, was one of the most important drivers in the promotion of IoT solutions. In our IOT invention manufacturing laboratory, we develop more than a dozen IOT prototypes at this stage. Undoubtedly, Luzea was one of the most complete projects of this period.

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 point in the world.

In a very important number of churches, including some in the Vatican, physical lamps have been included, which are especially related to the design of the characteristic interiors of churches. From the mobile app, from any geographical point, users can light the candles and see them in real time.

Case 02. Corner Pennant with Camera

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 game in the corner pennant proposes a unique vision in the transmissions of such a relevant sport in terms of number of users.

The evolution of the functional prototype has been released in the last final match of the Copa del Rey, played between Real Madrid and CA Osasuna.

Case 04. Humidor humidity control device

The preservation of cigars or cigars/Havanas depends mainly on the relative humidity of the containers in which they are stored, both in large and small quantities. For users, it is inconvenient to have to check the humidity inside the container every day to confirm if the humidity is within the recommended range. 

The IOT Humidor Controller device is capable of automatically reading the daily relative humidity, comparing it with the humidity parameters defined by the user, and in case it is outside of those parameters, it sends an SMS alert to the user.

The compression of the electronic system to avoid occupying spaces in the storage containers or humidors, as well as maximizing the battery life to more than 18 months of uninterrupted use, have been key challenges of the project.
