what steps does p>TRIZ usually take to solve problems?

Step 1: Analyze the composition of system and supersystem. Describe the composition of system

"System" refers to the system with problems, and the choice of system level has great influence on analyzing and solving problems. When the system level is too large, the system information is insufficient, which brings difficulties to analyze the problem; When the system level is too small, many important information may be missed. At this time, we need to make a concrete analysis according to specific problems.

Step 2: Determine the problems or contradictions in the system

When some components in the system fail to perform their necessary functions and show contradictions, find out the contradictions in the problems, analyze the reasons for the contradictions, and determine the root causes of the contradictions.

Step 3: Establish a problem model

Describe the functions of each component of the system (according to the results determined in Step 1). Imagine the components that perform different functions in the system as groups of small people, and show them in the form of graphics. The small people with different functions are represented by different colors, and a group of small people represent those components that cannot perform specific functions. At this time, the villain problem model is the model when there is a problem or a contradiction.

Step 4: Establish the scheme model

The problem model (with the figure of the villain) obtained from the research personifies the villain, endows the villain with certain initiative and "human" characteristics according to the characteristics of the problem and the functions performed by the villain, and puts aside the original problem environment, reorganizes, moves, cuts and supplements the villain so as to solve the contradiction.

Step 5: Transition from the solution model to the actual solution

According to the reformed solution of the villain, such as reorganization, movement, cutting and addition, we will return to the real problem environment from the fantasy scene, and turn the micro into the macro, so as to solve the problem.
