Abstract: In order to solve the problem of how to use patent information to help designers innovate and optimize the product structure, product innovation and optimization process based on TRIZ and patent analysis was proposed. Firstly, the patent documents that meet the functional and performance requirements was proposed by searching through the patent database, and some quantitative analysis with these documents was made in order to find valuable patents. Secondly, the functionprinciplestructure relationship of patents was extracted, and the most optimal solution of each function was obtained by the method of qualitative analysis, and a new program was gotten by integrating all available and new functions. Thirdly, conflicts of the program were solved using the innovate tools of TRIZ theoretical system, and the most optimal program was gotten. Finally, a case study was provided to illustrate the application of method.
Key words: patent; TRIZ; optimization process; innovative design
