Abstract

TRIZ 衝突分析 功能屬性 問題模式 TRIZ conflict analysis function attribute problem modeling
TRIZ theory has introduced numerous tools to solve problems. However, for the user the real problem is how to clearly define the problem itself as well as the possibility that the user does not thoroughly comprehend TRIZ itself. In the past, while solving the problem, user usually focuses on one point of the problem and practically abandons the need to consider the whole system of the problem. Thus, this research proposes a very systematic procedure. Starting from the first step in defining problem, this research proposes the importance to utilize 5W1H1G (What, When, Where, Why, Who, How, Goal) and also both technical and business constraints, which let user model the problem precisely. Then, it is followed by embedding TRIZ’s three kinds of solving problem tool, i.e. (1) Function-Attribute Analysis –draws a function-attribute diagram, identifies the system’s or component’s functions and attributes, then collecting patents from internet for reference, followed by expanding the attributes of components that are related in a harmful relationship (contradiction point) and matching them to engineering parameters; (2) Function-Relationship Analysis –draws a function-relationship diagram, then captures the system’s contradiction through the useful and harmful relationships from the drawing, and finally offers a list of III questions related to the problem solving; (3) Cause Effect Chain Analysis - identifying the negative factors in an engineering system, and using the cause-effect chain relationship to make a step-by-step drawback to find out the very initial problem, furthermore using the key negative factor as the input for Root Contradiction Analysis;(4) Root Contradiction Analysis –asks 5 Why’s (the first Why being the sore-point, and the other Why’s being its causes), then from user’s responses find out the likely improving and worsening parameters. The contradiction is found by using those tools, then based on the contradiction’s characteristics Contradiction Matrix (Technical Contradiction) or Separation Principles (Physical Contradiction) may be applied separately to obtain the final solution. This research also combines those four tools to achieve the highest effectiveness. An example is given to clearly show how the entire system runs. This research is intended to use final solution and the collected patents to inspire user finding the best solution to solve the problem.
