Over 30 Examples of Invention Prototypes

We convert ideas, patents, and inventions into functional prototypes with high chances of success. The integration of various disciplines in our invention manufacturing laboratory has allowed us to complete a catalog of over 200 functional prototypes with a final product look.

Below are some representative prototypes of what we do in our invention factory

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.

Patented invention US2023/0142882

Case 02: Mobile Phone Cleaning Robot.

It's an industrial machine or electromechanical robot designed to improve the cleaning of second-hand mobile phones that are intended to be resold. The ergonomic prototype not only reduces costs for companies engaged in the sale of mobile phones but also ensures a perfect quality standard in the cleaning and polishing process of screens, which is crucial for the renewed value of the device.

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.

Examples of Software Prototypes

Web Prototypes | App Prototypes

In our design and product invention development laboratory, it is true that 90% of prototypes have a fundamental component of electronics, design, and telecommunications. Precisely this trend of IOT prototypes, robots, and electronic prototypes has required us to include in our invention factory a team of developers skilled in both high-level software and low-level software.

Low-level Software: Low-level software is primarily responsible for managing hardware components and typically runs or executes 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 classified as 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.

Below 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 presented on this page of prototype examples, in categories such as IOT Prototypes, Electronic Prototypes, and similar ones, have required low-level programming to achieve their respective functions.
