专利壁垒已经成为我国企业市场竞争中的重要障碍，借助专利所提供的技术信息，通过专利的IPC聚类分析与技术成熟度结合，确定待规避的专利群及专利规避目标；应用元件权重分析提取专利群的技术特征，根据专利规避目标明确规避现有专利技术范围的技术研发方向；以技术研发方向为指导建立创新中所要解决发明问题的TRIZ标准化模型，并应用TRIZ的知识工具解决该发明问题，得到专利规避设计的原理解，结合现有专利技术的优势开发出具有创新性技术的新产品，从而实现了对现有专利群的创新规避设计。以封隔器为实例，应用IPC聚类分析与TRIZ结合的专利群规避设计流程进行封隔器的专利规避设计，开发了二次坐封封隔器并申请了相关专利。

Patent barriers have become a major obstacle to China’s enterprises in the market competition. With the technical information provided by the patents, the combination of patent’s IPC cluster analysis and technical maturity is used to determine the circumvented patents and patent avoidance goals. Components weights analysis is applied to extract the technical characteristics of patent clusters, according to the patent circumvention target technology research and development direction is identified to design around existing patented technology range. Technology research and development direction guides the designer to construct TRIZ standardized model of invention problem which is solved to realize innovation, the designer applies knowledge tools of TRIZ to solve the invention problem and gets the original understanding of the patent design around. Combining the advantages of existing patented technology the designer can develop new products with innovative technology, enabling innovative design around to the existing patent group. Taking the packer as an example, the application patent group design around process of IPC cluster analysis and TRIZ is to design around packer patents, develop secondary seat packer and the apply for related patents.
