Technology Innovation Opportunity Driven Patent Design Around

With the increasing in the number of patents,patent protection scope is more and more widely,haven fewer opportunities to technological innovation,and it’s becoming more and more difficult to be found.The current patent design around mainly studies how to copies the function of the patent protection structure,lack of the process of mining and analysis the deep knowledge on the patent.This passage divides the Patent Design Around into two stages,mining of patent knowledge and avoid design.Aiming at the problem of patent knowledge chaos,introduces the method of technology-function matrix to dug out the technology innovation opportunities.And put forward the method of mining the function knowledge of patent and the avoid design based on the axiomatic design and the theory of module.Because the patent document contains most of the technical knowledge and requirements,in the process of the patent knowledge mining,technology innovation opportunity can be predicted through the number of changes between surface knowledge,and then complete the innovation knowledge mining of patent,so as to guide the avoid design of the technology innovation opportunity.Mainly involves the following several aspects:1.Technological innovation opportunity of miningPatent contains the rich technical knowledge,and can achieve perfect effect of one or more functions.Based on the surface knowledge of patent,build the technology-function matrix and the effect-demand matrix,and based on the effect-demand matrix to evaluate the technology concentration and the bare of technology-function matrix,dug out in line with market demand of technology innovation opportunity.2.The bare of technology innovation opportunity driven patents around the designThe number of the bare is relatively small,the goal patent of patent design around can be determined by comparison.Put forward the method of the target patent innovation knowledge mining,based on functional decomposition of TRIZ and axiomatic design,and the process of mining functional knowledge and the mapping transformation process in detail.Obtains the thought of patent design around,and achieve the innovation design of the goal patent.3.The technology concentration of technology innovation opportunity driven patents around the designThe number of the technology concentration is large.It have a variety of technical structure for the same function.Based on the functional division and the module partition theory,the method of kin patent functional knowledge is proposed,and the function module partition in detail in this paper.Basis on the function knowledge,combines the demand knowledge to get the thought of patent design around,realize the patent design around.4.The design around of the cable row machine of winchFor the cable row machine of winch when light cable can’t realize orderly rope,introduce the method of mining technology innovation opportunity.Combining with the theory of axiomatic design and module partition,complete the cable row machine of winch patent knowledge mining,and complete the avoidance design.Realize the orderly rows of cord wire rope light movement.
