Prototypes, according to Wikipedia, are described as a type, form or instance that serves as an example for other things in the same categories. When a designer creates a new something there is always great uncertainty as to rather it will work as planned. Since anything new usually has a great many problems before it actually operates as it is expected, a prototype is used. This gives the designers or developers the opportunity to either verify their product as operational or that the design when complete will be accepted by the buyers. Existing systems or products are analyzed for their usability prior to proceeding with the new item.
Following existing prototypes research has ventured into a wide variety of projects. These designs and productions include specialty vehicles, replica aircraft, desks, wall hangings, amusement park rides and movie sets. There are companies that specialize in creating practically anything a person might have in mind. Practically any fantasy idea is possible.
There are four basic prototype categories, or as some may prefer, “models”. A Proof-of-Principle Prototype gives the inventor a chance to inspect the prototype thoroughly to prove if certain working parts of their product will actually work or not. Form Study Prototypes give the inventor the opportunity to judge the feel, look and size of the product. Visual Prototype gives an idea of the color and appearance of a product. Functional Prototypes will operate as similar as possible to the product that is in process of being manufactured. This final test reveals all problems with the new product and gives the inventor the opportunity to make all the corrections.
