Abstract
In this research, Many people understand that the (accidental) tip and the "analogy" that leads to it have played a central role in many instances of creative problem solving.And it has been pursued as a way to get more hints to make a 'knowledge base' which is a collection of many cases. The Unified Systematic Inventive Thinking (USIT), which makes it easier to apply TRIZ, will seek out various ideas through a process of analyzing the current system and examining the ideal system more clearly. In this paper, we describe the rationale and application procedure of the "6 step thinking method" which improves the "4 step thinking method".
