Standards provide two functions:
A factory produces a new type of steel. Different additives are placed into the mix and stirred into the molten steel. In order to prevent the blades of the mixer from melting away during the mixing process, the blades  must have a protective coating. However, this coating may pollute the mixture of molten steel. What can be done?
Elements of the existing System:

Molten steel

Mixing container

Additive Intake

Blades that stir molten metal

S-Field modeling of a technical system is performed in the Operating Zone, the area where the core of the problem. The diagram above shows a graphical model of the molten steel mixer problem. S1 is the blade, S2 is the molten steel, and F2 is the thermal energy of the steel that melts blade S1. The wavy arrow represents a harmful interaction between the hot molten steel (S2) and the blade (S1). To protect the blade, a third substance, S3, must be introduced. In this case, S3 is a modification of S2. By providing cold (F3) to blade S1, a crust from the molten material will develop on the blade’s surface and protect it from melting.

Altshuller offered 76 Standards divided into five classes:
