We solve a problem exactly in order to understand what system we need to eliminate a disadvantage. The idea of solving any problem is a description, with a varying degree of detail, of the technical system that eliminates the disadvantage, and its functioning features. In this case, special attention is paid to the structure and functioning of the key components of the system, the introduction of which into the problem system made it possible to solve the problem.
When verbalizing a problem solution, it is often enough just to name the desired component. Sometimes it is necessary to describe in more detail its implementation and functioning features. In case of a complex problem and an unobvious solution, it is necessary to describe the device and system operation quite clearly. It is of no importance whether we are dealing with a full or curtailed description of the problem solution. In any case, it is based on the understanding of what system gives us a possibility to eliminate the disadvantage and how that system works.
The most convenient way is to present the desired system as a model of the simplest technical system. It is on the basis of this model that we can present the full composition and structure of the technical system, understand its structure and functioning features, and highlight its peculiarities that are important for the elimination of the disadvantage. In other words, we can describe the idea of the problem solution.
Let us recall the principles of building a model of a technical system:
- the system must satisfy the law of completeness of its parts, i.e. the system composition must conform to the function performed;
- energy must pass through all parts of the system freely and without causing harmful phenomena;
- the functioning of the system must be coordinated.
