There are eight laws of technological system evolution in TRIZ system, which are the constitutions of TRIZ world:
1) Law of Completeness: Any engineering system evolves in order to have four basic parts – engine, transmission, working tool, and control system.
2) Law of Energy Conductivity: Any engineering system evolves in order to have easy end -to-end flow of energy through all components.
3) Law of Harmonization: Any engineering system evolves in order to have well coordinated rhythms (frequencies) of all components.
4) Law of Idealization: Any engineering system evolves in order to become more ideal.
5) Law of Non-uniformity: Parts of an engineering system evolve at different rate, the system’s evolution rate depends on its lowest part evolution rate.
6) Law of Transition to Super-system: Any engineering system evolves in order to become a part of more complex super-system.
7) Law of Transition to Micro-Level: Any engineering system evolves in order to make working tools functioning on micro-level.
8) Law of Substance-Field Evolution: Any engineering system evolves in order to substitute:
