Because TRIZ's innovative principles are based on patent analysis, some principles are the accumulation of experience, and the surface principle is the summary of this experience. The principle of curved surface tells us that when faced with system problems, we can look for linear situations, relationships, straight lines, planes and cube shapes in the system, and try to change them into what new functions can be realized or obtained under nonlinear conditions. Of course, compared with straight lines and cubes, circles and spheres do have some advantages in geometric characteristics such as symmetry:
A. The circumference is the same, and the circle contains the largest area; A circle is completely symmetrical about its center;
B. With the same area, the ball can hold the largest volume, and the ball is completely symmetrical with the center point;
However, it should be pointed out that this advantage has not led us to use the principle of surface modification, but surface modification is an attempt:
2. Multifunctional principle: Let an object perform a variety of different functions, so that other parts can be removed. The "light-catching louver" in the urban best practice area can automatically track the position of the sun and realize various functions such as shading and lighting.
The principle of universality, also known as the principle of universality, is expressed as follows:
A. make an object have multiple functions;
B. After eliminating the necessity of functions in other objects, further cutting other objects;
There are two ways to make an object have multiple functions. In the first case, by making the product have multiple functions, the value of the product can be increased and the product can be more competitive. In the second case, by combining multiple related functions into one product, the overall cost can be reduced and it is convenient to use. In addition, the values mentioned in the first case can be obtained. These two cases are similar to some cases in combination principle.
3. Pre-compensation adopts pre-prepared emergency measures to compensate objects with relatively low reliability such as parachutes on the plane.
