The general flow of the product design includes product planning, conceptual design, modeling design, visual design and structural design. The importance of the industrial design is self-evident. For the current industrial design, the design of every link is no longer limited in its specific range like the beauty but towards the diversified development. The purpose, features and diversification of product appearance determine its future direction of development-the combination of appearance, function and technology, and the ultimate goal is to make products serve customers better and achieve humanized design.
