Abstract: To mining deep patent knowledge,by analyzing the technical characteristics of claim against in patent document,the each element of patented product technology system was confirmed.According to the directions of technology content and implementation plan,the interaction relationship between the technology elements was determined,and the function model of patent technology scheme was established.The general function model of patented product was refined based on function model.According the connection relationship of function model,the technical (structure) hierarchy tree of patent products was built,and the function hierarchy tree of patent product was mapped based on theory of axiomatic design which could verify the accuracy of transformation process with customer requirements.At the same time,the function model could guide the construction of design matrix,which ensured the rationality of mapping process.The inventor's technological innovation process was restored by mapping process of customer domain,functional domain and physical domain,and the deep knowledge of patent was dug,which could fully understand the technical scheme and provide technical support for patent around design.The cow dung dryer design was taken as an example to dig the patent knowledge mining of conceptual design,and the effectiveness of proposed method was verified.

Key words: patent around, knowledge mining, innovation design, axiomatic design
