The third category of prearranged invention principles includes

The third type of prearranged invention principle includes precautionary measures.

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. In order to meet the needs of people's daily lives, inventions provide unprecedented models of artificial natural objects, new processes and methods of processing and production, as well as machinery, equipment, instrumentation and various consumer products.

In the field of intellectual property, invention is one of the types of patents protected by the Patent Law. It refers to new technical solutions proposed for products, methods or their improvements. Invention is different from scientific discovery. Invention is mainly about creating things that did not exist in the past, while discovery is mainly about revealing the existence and properties of unknown things.

Inventions are novel technological achievements and are not simply imitations of existing artifacts or repetition of plans and measures proposed by predecessors. A technical achievement cannot be called an invention if it can be found in an existing technical system that is identical in principle, structure and function.

Inventions must not only provide something unprecedented, but also provide something more advanced than previous technologies, that is, superior to existing technologies in terms of principle, structure, and especially functional benefits. Inventions always involve both inheritance and creation, and most of them are advanced in general.

Characteristics of inventions:

Inventions must be innovations with application value, they must have a clear purpose, and they must be novel and advanced in practicality. The invention plan must not only reflect the attributes, structures and laws of external things, but also reflect its own needs. Before the inventor creates a new product or new process, he has already pre-constructed the designed object according to the functional requirements in his concept, and during the invention process he constantly improves his plan according to the optimized functional goals.

Inventions are different from actual technology or on-site technology in actual production and engineering. Inventions must have application prospects and possible applied technical solutions and measures. Whether an invention can be applied to production processes or engineering activities also depends on whether it can be incorporated into existing technical systems or cause innovation in existing technical systems, and Capital, equipment, manpower, materials, management and market conditions.

With an invention, there may not necessarily be a corresponding product or process, and it may not be able to solve practical problems in production and engineering. Only when inventions are transformed into product development, process testing, and technological innovation, trial production, mass production, and promotion and application can they become real technologies.
