中文摘要：

针对如何利用专利知识信息帮助设计者对产品结构进行创新和优化的问题，提出了基于专利分析法和TRIZ的产品结构创新与优化设计流程。该流程首先通过对专利库的检索，获取符合功能与性能要求的专利文献，并对这些专利进行定量分析，获取对研究有价值的专利；再提取各专利的“功能一原理一结构”关系，运用专利定性分析法，获取各功能最优解决方案，整合所有现有功能和新增功能，初步得到新方案；然后通过选择TRIZ理论体系中的创新工具解决初步方案中的冲突矛盾，获得最优化的新方案；最后，给出了该流程的实例应用。

英文摘要：

In order to solve the problem of how to use patent information to help designers innovate and optimize the product structure, prod- uct innovation and optimization process based on TRIZ and patent analysis was proposed. Firstly, the patent documents that meet the func- tional and performance requirements was proposed by searching through the patent database, and some quantitative analysis with these docu- ments 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 a- vailable 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.
