TRIZ theory is a knowledge-based, people-oriented and systematic methodology for inventing problems, which is essentially a routine and step to analyze and solve problems, that is, an algorithm. This theory comes from the study of the inherent law of invention and creation, but its thought can be further extended to the analysis and solution of all problems, from the philosophical level to the philosophical level, and it also provides many concrete tools.
Modern TRIZ theory system mainly includes the following aspects:
1, innovative thinking methods and problem analysis methods
TRIZ theory provides a scientific method to systematically analyze problems, such as multi-screen method. For the analysis of complex problems, it includes the scientific problem analysis and modeling method-material field analysis method, which can help to quickly confirm the core problems and find the fundamental contradictions.
2. Evolution law of technical system
According to the evolution law of technical system, on the basis of a large number of patent analysis, TRIZ theory summarizes and refines eight basic evolution laws. Using these evolution laws, we can analyze and confirm the current technical state of products, predict the future development trend and develop competitive new products.
3, the principle of solving technical contradictions
Different inventions often follow the same rules. TRIZ theory summarizes these laws into 40 innovative principles. In view of specific technical contradictions, we can seek specific solutions based on these innovative principles and combined with engineering practice.
4, innovative problem standard solutions
According to the different characteristics of the material field model of specific problems, there are standard model processing methods, including model modification, transformation, additive field and so on.
5. Invent ARIZ, a problem solving algorithm.
Mainly for technical systems with complex problems, contradictions and unclear related components. It is a non-computational logical process of a series of deformation and redefinition of the initial problem, which realizes the step-by-step in-depth analysis, transformation and solution of the problem.
6. Knowledge base based on engineering principles such as physics, chemistry and geometry.
The knowledge base based on the analysis results of millions of invention patents in physics, chemistry, geometry and other fields can provide a rich source of solutions for technological innovation.
