The popularization and application of triz innovation method in enterprises should be implemented step by step from simple to complex. From the previous system function analysis and the definition of the final ideal scheme, it can be seen that it is relatively easy to introduce innovative methods at the subsystem level, but it is more difficult to establish a lean R&D system at the system level. The most difficult thing is that the construction of enterprise innovation mechanism at the super-system level is the most complicated.

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, there are objective evolutionary laws and patterns. Secondly, the continuous solution of various technical problems, conflicts and contradictions is the driving force to promote this evolutionary process. Then the ideal state of technical system development is to realize as many functions as possible with as few resources as possible.

The core of the theory of invention problem solving is the principle of technological evolution. According to this principle, the technical system has been evolving, and conflict resolution is the driving force of its evolution. The speed of evolution decreases with the resolution of general conflicts in technical systems, and the only way to make it mutate is to solve the deep-seated conflicts that hinder its evolution.
