The Use of the Nine-Screen Method in TRIZ Theory and the Analysis of Common Problems

【目的】针对目前国内出版的众多TRIZ教材、专著和论文中有关九屏幕法的讲述内容过于简单、使用基本规则不明确等问题,进行分析研究,旨在为高校学生和企业TRIZ创新方法应用者提供借鉴。【方法】在介绍九屏幕法的作用及相关概念基础上,通过对九屏幕法使用的具体描述、对使用中常见问题的归纳分析等,系统性阐述了九屏幕法使用的基本规则。【结果】明确了九屏幕图的主要形式、绘制方法和使用要点,归纳总结出不符合使用要点、形式错误、缺少对应性和表达与本质不一致等4种错误形式。【结论】九屏幕法对拓宽解题思路具有重要作用,初学者比较容易上手,但是在使用中经常出现各种问题,需要使用者在实践中不断深入理解,深化应用,以更好地发挥九屏幕法的作用。

[Purposes]This paper presents the analysis and research of the problems that the content of the nine-screen method is too simple and the basic rules of using it are not clear in many TRIZ teaching materials,monographs and papers published in China,aiming to provide reference for students in colleges and universities and applicants of corporate TRIZ innovation methods.[Methods]Based on a brief introduction of the role of the nine-screen method and related concepts,this paper systematically elaborates the basic rules of the nine-screen method through the specific description of the use of the ninescreen method and the generalization and analysis of the common problems in the use of the nine-screen method.[Findings]The main forms,drawing methods and points of use of the nine-screen diagram are clarified,and four kinds of errors are summarized,such as fail to meet the use of the main points,form error,lack of correspondence,and inconsistency of expression with essence.[Conclusions]The ninescreen method plays an important role in broadening the idea of problem solving,and it is relatively easy for beginners to get started,but various problems often occur in the use of the method,which requires us ers to deepen their understanding and strengthen their application in practice in order to better utilize the role of the nine-screen method.
