| As the key to the survival and development of enterprises,innovation was the necessary way to extend and strengthen the vitality of enterprises.In the current trend of technological development,enterprises needed to constantly innovate technology,accelerate the design cycle,and carried out innovative product design without technology infringement.This put forward higher innovative design requirements for designers.By virtue of the technical information in the patent,it not only contained the latest information of technological development and the situation of competitors,but also can helped enterprises to develop and made reasonable strategic layout.Therefore,how to make good use of the patent information to became a key step in the growth and development of enterprises.As a specific form of qualitative analysis in patent analysis,technology-effect matrix can uniquely present the degree of technology aggregation and evacuation in the development process of related technical fields to designers,visualize complex patent information and deeply into its obscure information.Helped designers identify technology hot spots and weak spots,technology hot spots can be circumvented and tracked and weak spots which was the technical shortcoming in the process of product evolution can help designer to created innovative designs.As an innovative design method,TRIZ(Theory of Inventive Problem Solving)reveals the potential law and mode of evolution of technology,and proposes a series of methods and tools to guided technological innovation,which can undoubtedly accelerate the generation of new solutions and speeded up the design cycle.This paper proposes a set of complete design process to avoid technology duplication and infringement,improve the success rate of product innovation,and make up for the technological imbalance in the process of product evolution.The target patent database was sorted out by searching,screening and noise reduction.Each patent was analyzed and marked,and technical means and effects were summarized,In view of the difficulty in summarizing technical means,this paper proposes a way of summarizing technical means based on the principle of invention,and constructs the technology(principle of invention)-effect matrix.The design objective is derived from the technical weak point of technology obtained from the technology(principle of invention)-effect matrix,and Used TRIZ tool to transform and generate the design plan,and finally applyed for a patent to complete the design goal after judging the infringement without error.The main content of the paper is:1.Based on the patent search website,searched patent with a technical field and became the initial sample base.The initial sample was screened through the Boolean operation of IPC and keywords,and the remaining patents were screened in the way of rapid reading,so as to eliminate the patents with meaningless noise points to the research target,and achieve the most accurate screening to obtain the final target patent database.2.After careful reading the target patent database,the corresponding technical means and technical effects were summarized through the patent information summary table.The technical effects were summarized similar meanings,and the technical means were summarized through the principle of invention.Thus,the technology(principle of invention)-effect matrix is constructed.3.Through the technology(principle of invention)-effect matrix,the technical weak points in the relevant technical field were obtained.And from this,the design objective can be obtained.The conflict matrix of TRIZ tool and the principle of invention were applied to obtain the final design scheme.After the scheme was judged to be correct in patent infringement,the patent was applied to complete the design goal.4.Using the above design process,taking the agricultural rotary tiller patent as an example,the innovative product design of rotary tiller was carried out,and the new rotary tiller design scheme was obtained and related patents were applied,which verified the feasibility of the design process. |
