Research of Design Method of Product Function Analysis and Combination

This paper adopts methods of longitudinal comparison, classification research, expand competition field to research for design method of product function analysis and combination based on user research. It found initiative combination of product function and technique could share technology platform and spare module organization to form different varieties of product in functional detail, market orientation, and functional emphasis, avoid to carrying out fierce competition with competitor in narrow market area. It is benefit for company pursuing different strategy. R&D team should maintain validity and direction of design, analysis, and manufacturing work. High efficient pursuing situation from competitor, sale situation from user market would increase urgency and psychological pressure of R&D team and manufacturer, thus improve efficiency of research and development. The results show that fundamental goal of R&d team carries on product function analysis is tightly grasp functional use essence of future products to allocate various of resources to achieve product function index, satisfy user demand by best way.
