The contradiction matrix is a 39×39 contradiction matrix table compiled by Achschuler, which organically links 39 general engineering parameters with 40 invention principles. It is the result of Achschuler's research on 2.5 million patents, and the matrix is very compact and self-contained.
Achshuler organically linked 39 general engineering parameters with 40 invention principles, established corresponding relations, and arranged them into a 39×39 contradiction matrix table. The shield matrix table is the result of Achschuler's research on 2.5 million patents. The matrix is very compact and independent.
According to two general engineering parameters in the system, users can directly find out the invention principles to solve contradictions from the matrix table and use these principles to solve problems.
Line 1 of the contradiction matrix is the code of 39 general engineering parameters, and line 2 is the name of 39 general engineering parameters respectively. However, the vertical line indicates the parameters to be improved and the horizontal line indicates the parameters to be deteriorated.
39x39 Engineering parameters form the square of the matrix from the row and column dimensions *** 152 1. In the box of 1263, there are several numbers, which are the codes of the invention principles recommended by TRIZ to solve the corresponding technical contradictions.
