In the triz theory, how many principles of invention are there?

The RIZ theory classifies inventions into the following 5 levels:

Level 1: Mostly small inventions of the parametric optimization category, generally of common design or simple modifications to existing systems.

Level 2: Minor improvements to existing systems by resolving a technical contradiction. The solution of this type of problem mainly uses the existing theory, knowledge and experience in the industry.

Level 3: Fundamental improvements to existing systems. The solution of this kind of problem mainly adopts existing methods and knowledge outside the industry, and the contradiction should be resolved in the design process.

Level 4: Adopt new principles to complete the innovation of the basic functions of the existing system. The solution of this kind of problem is mainly from the perspective of science rather than from the perspective of engineering, and it is necessary to fully control and use scientific knowledge and principles to realize new inventions and creations.

Level 5: Rare scientific principles lead to the invention and discovery of a new system. The solution to this type of problem is mainly based on the laws of nature.

New discoveries or new discoveries of science.

If I had to make it hierarchical, I would personally turn it into 3678.

The TAG theory holds that the hierarchical stage of creation and invention is divided into three hierarchical stages.

The theory is that there are several levels of invention: first, we have to design according to the market demand, and second, according to your individual needs.

GUI theory argues that there are many levels of creation and invention, including many contents.

The principle of solving technical contradictions, different inventions and creations often follow common laws. TRIZ theory summarizes these common laws into 40 innovation principles, and for specific technical contradictions, specific solutions can be sought based on these innovation principles and combined with engineering practice.

Standard solution method for innovative problems: According to the different characteristics of the object-field model of the specific problem, there are standard model processing methods, including model trimming, conversion, addition of matter and field, etc. Dust fiber.

It is a series of non-computational logical processes such as deformation and redefinition of the initial problem, so as to achieve a gradual in-depth analysis of the problem, problem transformation, and problem solving.

The knowledge base built based on engineering principles such as physics, chemistry, and geometry, and the knowledge base built based on the analysis results of millions of invention patents in the fields of physics, chemistry, and geometry can provide a wealth of solutions for technological innovation.

Former Soviet inventor Alih Shuler.

The triz theory was developed by the former Soviet inventor Alih Shuler s.Founded in 1946, Altshuller is also known as the father of Triz.

In 1946, Altshuller began research on the theory of solving problems in the invention manual. At that time, Altshuller was working in the patent office of the Caspian Navy of the former Soviet Union, and in the process of processing the patents of famous inventions from all over the world, he always considered the question: when people invent and solve technical problems, are there scientific methods and laws that can be followed, so that new inventions can be quickly realized or technical problems can be solved?

The answer is yes! Altshuller found that product improvement, technological change, innovation, and biological systems in any field have a pattern of generation, growth, maturity, aging, and extinction. If people grasp these rules, they will be able to actively design products and eliminate the future trend of products.
