Abstract: By exploring the processes and rules of designer's innovation cognitive thinking,an general solving process model for innovative problem was refined and a compound rhombus thinking process model was summarized.Combined with the current situation of product design and new product development,the methods such as quality function deployment,su-sield model,contradiction matrix and morphological analysis were applied to the thinking operation units such as problem analysis,concept solving and combinatorial optimization.An integrated multi-method strategy and a design process for product innovation were proposed,and the corresponding design prototype system was developed.The nailing machine was taken as an example to verify the effectiveness and practicality of the proposed strategy and system.

Key words: cognition, creative thinking, compound rhombus thinking process, multi-method integration, prototype system, product design
