Method and Application of Patented Design Around by Combination of IPC Cluster Analysis and TRIZ

doi:10.3901/JME.2015.07.144

Abstract

Abstract: 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.

Key words: IPC cluster analysis, patent design around, patent group, TRIZ
