[0002] A prototype refers to one or more functional prototypes made based on the product appearance drawings or structural drawings without making a mold. It is used to check the rationality of the appearance or structure. The prototype is the most direct and effective way to verify the feasibility of the product and find out the defects, deficiencies and disadvantages of the designed product, so as to make targeted improvements to the defects. Whether the prototype is feasible needs to be tested based on the size. The commonly used method is to measure it with a caliper.

The range of size detection is narrow. For prototype models with complex structures, the detection is more difficult, time-consuming, and the accuracy is low, which affects the subsequent production of workpieces. Utility Model Content
