The basic philosophy of TRIZ theory includes the following six items:
1. All engineering systems obey the same development rules. This rule can be used to study the effective solution of the problem of invention, and also to evaluate and predict how to solve the solution of an engineering system (including new products and new service systems).
2. Like social systems, engineering systems can be developed by solving Conflicts.
3. Any problem of invention or innovation can be expressed as a conflict between requirements and prototype systems that cannot (or can no longer) meet these requirements. Therefore, "solving the invention problem" and "finding the solution to the invention problem" mean solving the conflict when compromise and reconciliation cannot be adopted.
4. In order to explore the solution to the conflict problem, it is necessary to use the knowledge of physics or other science and engineering that is unknown or unfamiliar to professional engineers. The classified knowledge base corresponding to the technical function and the effects of physics, chemistry and biology that may realize this function can be a pointer to explore the solution of conflict problems.
5. There are reliable criteria for evaluating each invention. These criteria are:
(1) Is the invention based on a large number of patent information? Invention projects based on a few cases discovered by accident are not serious research results. Facts have proved that a major or important invention project is usually based on no less than 1, to 2, patents (or intellectual property rights/copyrights) research.
(2) Have inventors or researchers considered the level of invention problems? A large number of low-level inventions are not as good as one or a few high-level inventions. Because low-level inventions can only be used in simple situations.
(3) Is this invention a conclusion or suggestion extracted from a large number of high-level experiments?
6. In most cases, the theoretical life is consistent with the development law of machines. Therefore, it is difficult to produce two or more system solutions by "trial and error" method.
