TRIZ was not the first to introduce the notion of ideal machine. Equally it was not the first to propose the criteria of a minimally workable machine. The first was thermodynamics.

The first ever proposed ideal machine was Carnot ideal heat engine. And the first criteria of a minimally workable machine were the criteria of the minimal workability of heat engines in the form of the laws of thermodynamics (see this article for details).

Later the notions of ideal machines appeared in other areas of engineering. For example, in electrical engineering the notion of ideal electrical machines were introduced, such as ideal transformer, ideal transistor, ideal DC generator, etc. In bio-engineering the notion of ideal semipermeable membrane was introduced as a membrane permeable to water only, but impermeable to all solutes. Etc.

TRIZ, in contrast, ventured to give general criteria of ideality and workability of any technical system, not heat engines only and not electrical machines only. However, while TRIZ definition of the ideal technical system was a success, its criteria of the minimal workability were a failure (see this article for details).

Actually, Altshuller attempted to give criteria of the minimally workable technical system twice. The first time it was within SuField analysis, when he declared that to be minimally workable a SuField has to have 2 substances and one field. The second attempt was within the laws of evolution, when he proposed the so called "static laws", stating that to be minimally workable a technical system should have engine, transmission, and working means, thereby putting such engineless and transmissionless technical systems as chairs, tables, houses, etc. beyond the scope of the law.

This issue of the journal presents the first really general criterion of the minimal workability applicable to any technical system. Along with the general ideality criterion proposed in the previous issue of the journal, it lays the foundation of a new discipline, technodynamics, aimed at studying workability, viability, and ideality of various technical systems.
