Usually the products that have just been developed or designed need to be prototyped,
The prototype is the first step to verify the feasibility of the product. It is the most direct and effective way to find out the defects, deficiencies, and drawbacks of the designed product, so as to improve the defects in a targeted manner, until the deficiencies can not be found from the individual prototype samples.
Prototypes are divided into three categories:
(1) Appearance prototype: Mainly inspect the appearance design of the product, requiring exquisite appearance, accurate color, and low requirements for internal processing.
(2) Structural Prototype: Mainly check the structural rationality of the product. The requirements for the size are relatively high, and the requirements for the appearance are relatively low. Foreign countries have particularly strict requirements on this type.
(3) Functional prototype: It is required to achieve the same appearance, structure and function as the real product. It can be understood as a finished product that is not on the market. It is the most demanding and difficult type of prototype.
