TRIZ deals with key development rules of artificial systems. Artificial systems evolve in accordance with a specific set of laws. These rules can be studied and then applied to the task of solving invention problems without searching through masses and masses of low-efficiency solutions.
The main law of the evolution of technical systems is "increasing the degree of system ideality". A more ideal system will be that in which the amount of necessary materials, its dimensions, the power consumed by it, its cost etc. are fewer/smaller, while the number and quality of functions performed are greater/higher.
TRIZ teaches us to think in a systematic way: an artificial system or a phenomenon under investigation are viewed as developing systems with their past, present and future, as systems made up of elements/parts and in their turn being elements/parts of some bigger systems.
Systems develop by way of overcoming contradictions. Different parts of a system may develop unevenly, which leads to new contradictions hampering further development of the whole. A contradiction arises when an attempt to improve one parameter of an artificial system results in unacceptably worsening another parameter. A task is very difficult because it contains inherent contradictions in it. To solve a problem/achieve a task means to overcome a contradiction, i.e. to satisfy contradictory requirements. In TRIZ the process of invention is viewed as a process of revealing, analysing and removing contradictions.
