The third-level invention in TRIZ theory refers to the method of improving and innovating the technical system, which is also called "system-level innovation". This method is mainly used to solve some complex problems and improve the overall performance and efficiency of the technical system at the same time. In TRIZ theory, the invention of the third level usually includes the following aspects:
1. Model transformation:
This method regards a specific problem or technical system as a model, and through comparison and transformation with other different models, new improvement and innovation schemes can be found.
2. Standardization:
This method unifies the management and control of processes, equipment and components in the technical system by formulating appropriate standards and specifications, thus improving the efficiency and quality of the whole system.
3. Function expansion:
This method can achieve more comprehensive and efficient performance by adding, changing or redesigning some functions of the technical system. For example, on the basis of having only the functions of calling and short messages at first, smart phones have continuously expanded their functions by adding various applications and functions.
4. Structural optimization:
This method makes the technical system more stable, reliable and efficient by redesigning and optimizing the structure of the technical system. For example, in the design of electronic products, adopting the modular and integrated design concept can greatly improve the performance and stability of the whole system.
5. Process improvement:
This method improves the production efficiency and quality of the system and reduces the cost by optimizing some processes such as manufacturing, testing and operation in the technical system.
In a word, the three-level invention in TRIZ theory is a method to improve and innovate the technical system. By means of model transformation, standardization, function expansion, structure optimization and process improvement, complex problems are found and solved, so as to improve the overall performance and efficiency of the technical system and promote the progress and perfection of technology.
