The prototype of the invention cannot be ignored, since it tried to prove the concept of the inventor of potential customers, suppliers and investors – and, above all, the inventor. This is the opinion of most experts. The idea of creating a prototype – you are achieving great success in terms of creativity, which also without having to invest so much money in the idea of the product or go to your commitment at an early stage.
The construction of a “prototype of the invention,” at the right time: it is very important to build a “prototype of the invention,” long before buying the instrument to create a search for products or contractors. Many times it happened that the inventor might want to create a prototype much earlier than thinking too much about computer drawings. It is likely that he burned a large amount of cash in engineering drawings “” when perhaps what he needed – a pulp, which clearly shows what is judged. If so, it is recommended that you return to the drawings on the computer. Estimating the right time for a prototype is not that difficult. This simply requires proof of the operability of the product invented by the person in question.
Correct “a prototype of the invention” for the right audience, “the manufacture invention prototype” should be aimed at the right audience for their work. This means that the adaptation must be carried out in such a way that the requirements of the clients are satisfied with their satisfaction. In addition, the prototype should be able to transmit criticisms of potential partners, investors, suppliers and customers. Therefore, it should be taken into account that only friendly evaluations are not enough. The softer and more controllable the prototype, the better. However, it is advisable not to get carried away by the compliments. It is better to spend less on this production, since there will be many other places to spend initial capital.
Let> 1 be a prototype
If the overload is not much, allow the prototype of the manufacture invention prototype to be made in several versions. The inventor will probably improve the designs later. In this sense, the last product, arrived, would bring more money thanks to its modern and clear design. Some people also have the habit of creating two prototypes at the same time. The first is designed for “show” and the other for “go”, that is, E. can first be made similar to the final product, and the second.
For example, Battery Buddy had a prototype of “similar” and “work-like”. The first was created at the University of Michigan. In accordance with the engineering drawings, a box with the corresponding external dimensions was made. It was painted with beautiful graphics. This version can fit around 90% of the cars in the market. The second consisted of a plastic box. It was gray and about 4 times bigger than the actual Buddy battery. Then the end was not a problem. It was necessary to verify the operability; and it happened! Continue reading this http://www.prototypehouse.com/, the two versions simplified the task from the point of view of the buyer and seller.
