In the triz theory, patented technology solutions are divided into five innovations as follows:
No. 1: Most of them are small inventions of the parameter optimization type, generally ordinary designs or modifications. Systematic and simple improvements.
No. 2: Make small improvements to the existing system by solving a technical contradiction. The solution to this type of problem mainly uses existing theories, knowledge and experience in the industry.
No. 3: Make fundamental improvements to the existing system. The solutions to this type of problems mainly use existing methods and knowledge outside the industry, and conflicts must be resolved during the design process.
No. 4: Use new principles to innovate the basic functions of the existing system. The solution to this type of problem is mainly from a scientific perspective rather than an engineering perspective, and fully controls and utilizes scientific knowledge and scientific principles to achieve new inventions and creations.
No. 5: A rare scientific principle leads to the invention and discovery of a new system. The solutions to this type of problems are mainly based on new discoveries of natural laws or new scientific discoveries.
Extended information
In 1888, Darwin once defined science: "Science is the arrangement of facts, the discovery of patterns and the drawing of conclusions." Darwin's definition points out the connotation of science, that is, facts and laws.
Science should discover facts unknown to people and use them as a basis to seek truth from facts, rather than pure fantasy that is divorced from reality. As for laws, they are the inherent essential connections between objective things.
Therefore, science is a system of knowledge based on practice, tested by practice and rigorous logical demonstration, about the nature and laws of motion of various things in the objective world.
Invention is the process and result of applying the laws of nature to solve unique problems in the technical field and proposing innovative solutions and measures. Products are invented to meet people's daily needs. Inventions can be divided into useful inventions and useless inventions.
The results of inventions either provide unprecedented models of artificial natural objects, or provide new processes and methods for processing and production. Innovations and transformations in machinery, equipment, instrumentation and various consumer products, as well as related manufacturing processes, production processes and detection and control methods, are all inventions.
