Basic principles of TRIZ methodology
1. Problems and their solutions appear repeatedly in different application fields (subject fields).
2. The evolution of engineering system has laws to follow.
Inventions often use effects that exist in unrelated fields.
Principle 1:
The principle of problem reappearance in different fields (subject fields) and its solutions
Case 1: sweet pepper goes
Problem: The seeds and stalks of sweet pepper are connected with the pulp to form a complete sweet pepper, but when we want to eat sweet pepper, we will remove the stalks and seeds first, so that it tastes better. It's easy to remove the seeds and deal with a few sweet peppers. It can be solved by manual treatment, but what if you want to treat tens of thousands of sweet peppers at once?
Answer: You can put the sweet pepper in a closed container and then slowly increase the air pressure. With the increase of air pressure, the air pressure inside the sweet pepper also began to increase, and then the valve of the container suddenly opened, and the seeds and stems of the sweet pepper would explode.
Principle 2:
The evolution of engineering system is a rule to follow.
Case 1: development of keyboard
Generally, the keyboard we see is a piece of hardware that takes up a lot of space and is inconvenient to carry. In order to carry it conveniently, someone invented a folding keyboard. Although it is convenient to carry, it is not light in weight, and it is bulging and unsightly. For this purpose, the flexible keyboard came out, but after a while, some people think that the keyboard is still very troublesome. Is there any way to operate without a keyboard? Finally, someone used the optical projection mode.
Principle 3:
Inventions often adopt the principle of effect that exists in unrelated fields.
What does this principle mean? For example, Xiao Ming wants to make an invention today, but he doesn't know what the principle of this field is, and then uses it in other fields or occasions, which may produce unexpected results.
These are the three basic principles of TRIZ. Through these principles, we can know that most innovations or inventions are not brand new, but new applications of some existing principles or structures in new fields. You can see that many patents are actually the same, or a small improvement on the original basis can produce a new invention, which is also the result of TRIZ summarizing 500,000 invention patents, and TRIZ methodology believes that our subsequent innovative inventions can be further developed or improved on the basis of some existing inventions.
