As can be learned from his biography, Genrich Altshuller analyzed thousands of worldwide patents from the leading engineering fields. He then ana- lyzed solutions that were, in his judgment, most ef- fective. This work provided the first understanding of the trends, or patterns, of evolution for technical systems. It also laid the foundation for the develop- ment of an analytical approach to solving inventive problems, later becoming the foundation for TRIZ, his theory of inventing problem solving, with its axiom: The evolution of all technical systems is governed by objective laws . These laws reveal that, during the evolution of a technical system, improvement of any part of that system having already reached its pinnacle of func- tional performance will lead to conflict with another part. This conflict will lead to the eventual improve- ment of the less evolved part. This continuing, self- sustaining process pushes the system ever closer to its ideal state. Understanding this evolutionary pro- cess allows us to forecast future trends in the devel- opment of a technical system. Over the past 40 years, TRIZ has developed into a set of practical tools for inventing and solving tech- nical problems of varying complexity. Today, we can identify several basic TRIZ tools as well as other meth- ods and techniques that combine to makeup what is known as Systematic Innovation. Students and fol- lowers of Altshuller developed these additional tech- niques over the past 15 years. This section provides a short introduction to some basic TRIZ tools. It is here for two reasons: First, it is important for new readers to first learn TRIZ terminology and its meaning so that they may effectively utilize the 40 Principles to solve problems. Second, it is important for the reader to be familiar with the philosophy underlying TRIZ tools and tech- niques in order to be able to fully apply them. THE FOUNDATION OF TRIZ 1. Technical Systems: Everything that performs a function is a techni- cal system. Examples of technical systems include cars, pens, books and knifes. Any technical system can con- sist of one or more subsystems. A car is composed of the subsystems engine, steering mechanism, brakes and so on. Each of these is also a technical system unto itself (with its own series of subsystems) — and each performs its own function. The hierarchy of tech- nical systems spans from the least complex, with only two elements, to the most complex with many inter- acting elements. The table below shows the hierarchy of the tech- nical system called “Transportation.” In the left col- umn are names of technical systems. They are placed in descending order. Horizontal rows contain names of subsystems that belong to the technical system described on the left.
