Issue 1: Most of them are small inventions of parameter optimization, usually ordinary designs or simple improvements to existing systems.
Second, by solving a technical contradiction, make some improvements to the existing system. The solution of this kind of problem mainly adopts the existing theory, knowledge and experience in the industry.
Third, fundamentally improve the existing system. The solution of this kind of problems mainly adopts the existing methods and knowledge outside the industry, and the contradictions should be solved in the design process.
Fourthly, the innovation of the basic functions of the existing system is completed by adopting brand-new principles. The solution of this kind of problems is mainly from the scientific point of view, not from the engineering point of view, and fully control and apply scientific knowledge and scientific principles to realize new inventions.
Fifth: Rare scientific principles lead to the invention and discovery of new systems. The solution of this kind of problem is mainly based on the new discovery or scientific discovery of natural laws.
Extended data
1888 Darwin gave a definition to science: "Science is to sort out facts, find laws from them and draw conclusions". Darwin's definition points out the connotation of science, that is, facts and laws.
Science should discover unknown facts and seek truth from facts on this basis, instead of pure thinking fantasy divorced from reality. As for the law, it is the internal and essential connection between objective things.
Therefore, science is a knowledge system based on practice, tested by practice, and strictly demonstrated by logic about the nature and laws of motion of various things in the objective world.
Invention is the process and achievement of using natural laws to solve unique problems in the technical field and put forward innovative schemes and measures. The product was invented to meet the needs of people's daily life. Inventions can be divided into useful inventions and useless inventions.
The achievements of the invention either provide an unprecedented model of artificial natural objects or provide new technologies and methods for processing and manufacturing. The innovation and transformation of machinery and equipment, instruments and various consumer goods, as well as related manufacturing processes, production processes and detection and control methods, all belong to inventions.
