Good generic solutions across industries have been studied as part of the development of TRIZ. Altshuller and his researchers collected examples of repeated use of the same solutions from patent information. After painstaking work, the information on tens of thousands of good solutions was boiled down to 40 principles in the early 1970s.1 The use of these principles of innovation became an important branch of the theory. Various collections of standard solutions and principles for innovations were developed. To learn more about the research, see Savransky’s book2 and the paper by Zlotin and Zusman.3
