1, innovative thinking methods and problem analysis methods
TRIZ theory provides a scientific method to systematically analyze problems, such as multi-screen method. The analysis of complex problems includes the scientific problem analysis modeling method-material field analysis method.
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 evolutionary rules, we can analyze and confirm the technical state of current 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, adding material and field, etc.
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.
Characteristics of TRIZ theory:
1 and TRIZ are 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 uses knowledge in 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.
