The laws of technical systems evolution are the most general evolution trends for technical systems discovered by TRIZ author G. S. Altshuller after reviewing thousands USSR invention authorship certificates and foreign patent abstracts.
Altshuller studied the way technical systems have been invented, developed and improved over time. He discovered several evolutionary trends that help engineers to anticipate improvements that are most likely to make it advantageous. Convergence to ideality is the most important of these laws. There are two concepts of ideality: ideality as a leading pathway of a technical system's evolution, and ideality as a synonym of "ideal final result", which is one of the basic TRIZ concepts.

Famous quotes containing the words evolution, systems, technical and/or laws:
“The evolution of humans can not only be seen as the grand total of their wars, it is also defined by the evolution of the human mind and the development of the human consciousness.”
—Friedrich Dürrenmatt (19211990)
“In all systems of theology the devil figures as a male person.... Yes, it is women who keep the church going.”
—Don Marquis (18781937)
“The axioms of physics translate the laws of ethics. Thus, the whole is greater than its part; reaction is equal to action; the smallest weight may be made to lift the greatest, the difference of weight being compensated by time; and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.”
—Ralph Waldo Emerson (18031882)
“We agree fully that the mother and unborn child demand special consideration. But so does the soldier and the man maimed in industry. Industrial conditions that are suitable for a stalwart, young, unmarried woman are certainly not equally suitable to the pregnant woman or the mother of young children. Yet welfare laws apply to all women alike. Such blanket legislation is as absurd as fixing industrial conditions for men on a basis of their all being wounded soldiers would be.”
—National Womans Party, quoted in Everyone Was Brave. As, ch. 8, by William L. ONeill (1969)
