Top-layer Design and Systematic Design of Products

The A new design method of the products named "Systematize Design" has been advanced in this paper. From the view of the point of the system engineering, the planning of product design makes the product design qualities improve to a great extent. Besides the understanding of the client requirements, the design planning of products, the so-called 7D's: Design ideas, Design environments, Design objective, Design process, Design contents, Design methods and the Design quality evaluation, should be considered completely and planned systematically. Based on the previous work, the product design should be conducted according to the systematic design method. The paper makes a detailed expatiation of the systematic design method, viz. 1+3+X design method, in which 1 represents the optimal design for product functions, 3 means the design method synthesizing the dynamic optimization, intelligent optimization and visualized optimization combined organically, and X is the design method for the special requirements of the products.
