＜Features and usage＞
Ideas are created from five perspectives: principle names in two languages, meanings of principles, image diagrams of principles, all-real illustrations of sub-principles, and application examples in different fields. You can unconsciously expand (abstract) / reduce (concrete).
※ What is TRIZ（Overview & Contradiction Matrix Automatic Search）
＜Detailed explanation of how to use 40 principles＞
A.Customary scanning method
When a problem occurs, I can't afford to panic. Considering it as a contradiction problem, abstracting the problem, and then searching the contradiction table for the principle of invention would require considerable training. I would like to recommend that you familiarize yourself with the 40 principles of invention on a daily basis. Alternatively, after confirming the true purpose or root cause, scan all possible invention principles and come up with ideas. Even if you don't understand TRIZ itself, it is a powerful hint for those who want to cling to straw.
B.Invention principle extraction method from contradiction Matrix
Contradiction 39 × 39 characteristics (parameters) are arranged on the vertical and horizontal axes of the Matrix table. After abstracting the problem, if you select "improving characteristics" from the vertical axis and "deteriorating characteristics" from the horizontal axis, the "principle of invention" will be presented at the intersection of the two ( Automatic search for inconsistent Matrix ). We will come up with a solution using this principle of invention as a hint. For example, if you select "volume of moving object" for improving characteristics and "area of moving object" for worsening characteristics, "01 division principle", "04 asymmetry principle", "07 nesting principle", and "07 nesting principle" are selected at the intersections of the Matrix table. 17 "Principle of transition to other dimensions" can be confirmed.
