When developing new products, there is the temptation to follow psychological inertia, which is the tendency for the mind to jump to certain types of solutions for problems. This can lead to stunting of ideas and the diminishing of new concepts, leading to the establishment of a systemized approach to product development. TRIZ is a system that provides unique laws of evolution that can guide product development in a more comprehensive way.
There are nine laws of technical systems evolution that inform the TRIZ process. Static laws include the law of completeness of parts of the system, which dictates that four parts are required to complete a system, including the transmission, the engine, the working unit and control element. The law of energy conductivity of the system says that energy should be conducted freely through those four parts. The law of harmonizing the rhythms of parts of the system dictates that the periodicity must match up throughout each part of the system. The law of increasing ideality involves working toward the ideal final result, and the law of uneven development of parts dictates that the aforementioned parts will be made at different points and through different ways. The law of transition to a super-system states that a fully developed system moves to part of a super-system.
Dynamic laws of evolution include the transition from macro to micro level; parts and working organs are typically evolved first through bigger parts, and then their smaller components. The law of increasing substance field involvement involves the change from mechanics to electromagnets for powering the system.
