The origin of TRIZ finds itself in what is perhaps the biggest endeavor into human creativity ever conducted. Founded by the Soviet engineer inventor Genrich Altshuller from 1946 onwards by analyzing over 40,000 patent abstracts, it entails more than 2 million patent abstract analyses by today [1]. Altshuller found that the vast majority of problems that require inventive solutions typically reflect a need to overcome a dilemma or a trade-off between two contradictory elements.For example, the strength of a metal plate versus its weight. If one would want to make it stronger, it would also become heavier. That is, unless you use an innovative approach to overcome this technical contradiction. As such, the issue that this design technique is trying to solve is the demand for human creativity to come up with a solution to this trade-off. The central purpose of TRIZ-based analysis is to systematically apply the strategies and tools to find superior solutions that overcome the need for a compromise or trade-off between the two elements [2]. The technique is unique in the fact that it was not created for one discipline or specific industry. The technique is based on all the sectors and industries that are represented in the approach via analyzed patents. Its systematic approach has replaced the sporadic trial-and-error approaches in diverse areas [3]. Examples of implementation of TRIZ include: computer aided innovation (CAI) [4], Lean thinking [5] and project application [6].
