Objective: Aiming at the product design mode driven by user needs, improve and optimize the product design method process, effectively transform user needs into specific design, and improve the efficiency and quality of design. Methods: the user demand weight of QFD house of quality is calculated by FAHP method to effectively ensure the close combination of house of quality and user demand. The design parameters output by QFD house of quality are calculated by TRIZ theory, and finally the specific design is obtained. Conclusion: by using FAHP to improve the weight problem for user needs in QFD house of quality, find the optimal solution of the output layer of house of quality through TRIZ theory, integrate the application of three methods, effectively supplement the shortcomings between methods, and provide a new integrated design method.
