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.
Research institutions, universities and enterprises in the former Soviet Union formed a TRIZ research group, analyzed nearly 2.5 million high-level invention patents in the world, summarized the laws followed by the development and evolution of various technologies, and the innovative principles and laws for solving various technical and physical contradictions, established a comprehensive theoretical system composed of various methods and algorithms for solving technologies and realizing innovative development, and integrated the principles and laws of multi-disciplinary fields to establish a TRIZ theoretical system.
Extended data
Modern TRIZ theory system mainly includes the following contents:
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 rules, we can analyze and confirm the current technical state of products, predict the future development trend and develop competitive new products.
