Abstract: Nowadays, as the patent information is huge, patent avoidance design has important application value for the majority of enterprises to set up patent barriers hindering the later competition. The combination design of different patents is an important means to realize product innovation. A method of design around is proposed for heterogeneous product patents as heterogeneous product patents contain strong heuristic knowledge. Through retrieving patent database obtaining patents and extraction patent information, structure and function analysis is fulfilled, to construct a similarity matrix and a function element graph. After that avoidance objects are determined and a suitable strategy is chosen, using the basic principles of patent infringement as a guide, the design of the new circumvention plan is obtained. This process is applied on a multifunctional household finally.

Key words: avoidance design, heterogeneous product patent, similarity matrix, correlation analysis
