? 1. The evolution of technical system follows the life cycle of production, growth, maturity and decline.
2. Increase the ideality.
3. The unbalanced evolution of subsystems in the system leads to conflicts.
4. Increase the dynamics and controllability.
5. Increase the complexity and then simplify it through integration.
6. Matching and Mismatching of Parts
7. Evolve from macro system to micro system, and use energy field to achieve better performance or control.
8. Improve the degree of automation and reduce manual participation. ?
Among these eight models, ideal growth is a very important law in TRIZ theory. It shows that the technical system is evolving in the direction of increasing idealism. Ideality is a core concept of TRIz theory, which is defined as follows:
Among them, Uj refers to the useful results of the system, including all valuable results of the system; Hj refers to the harmful results of the system, including unnecessary expenses, energy consumption, pollution and danger. The ideal state of the system is that there are only useful results and no harmful results. The evolution from mechanical watches to electronic watches is a good example. TRIZ training theory holds that the ideal technical system does not exist in physics, but it must be committed to achieving the ideal final result. The ever-increasing idealism points out the direction of efforts for creative problem solving.
Practice has proved that the application of TRIZ theory can greatly accelerate the process of people's invention and creation and obtain high-quality innovative products. It can help us to analyze the problem systematically and find out the essence or contradiction of the problem quickly. It can accurately determine the exploration direction of the problem and will not miss all the possibilities. But also help us break through the barriers of thinking, break the mindset and analyze problems from a new angle; It can also predict the future development trend according to the law of technological evolution and help us develop competitive and innovative products. After more than 50 years of development, this legal system has been enriched and improved in practice, and achieved good application results and great social and economic benefits.
At present, system innovation methods and tools (TRIZ) play an irreplaceable role and efficacy in the following aspects:
Accelerators and amplifiers for product innovation/technological innovation/management innovation;
-A powerful tool for formulating the technical development strategy of excellent enterprises;
-Powerful tools and theories for building enterprise core technology patents;
-powerful tools and methods to break through the blockade of competitors' technology patents.
