First of all, whether it is a simple product or a complex technical system, the development of its core technology follows objective laws, that is, it has objective evolution laws and patterns;
Secondly, the continuous solution of various technical problems and contradictions is the driving force to promote this evolutionary process;
Third, the ideal state of technical system development is to realize the function of maximum benefit with the least resources.
TRIZ method
(1)TRIZ is the knowledge of inventing heuristic methods to solve problems. This knowledge is abstracted from patents all over the world, and TRIZ only adopts a few objective heuristic methods based on product evolution trend.
(2)TRIZ has applied a lot of effect knowledge in natural science and engineering.
(3)TRIZ applies the knowledge of the problem domain. This knowledge includes technology itself, similar or opposite technology or process, environment, development and evolution.
(4)TRIZ is a people-oriented method, that is, the heuristic method of TRIZ is oriented to designers, not machines.
