What is TRIZ?
There are two classes of sciences – specific and universal:
- Specific science that studies certain areas or objects – astronomy, physics, biology, Shakespearean studies, etc.
- Universal science that creates, studies and propose working methods for areas of specific science, such methods include logic, cause-effect analysis, mathematics and system analysis. Now TRIZ has joined them as a technology for solving creative problems in a wide range of specific areas of knowledge.
TRIZ is a technology for solving creative problems in a wide range of specific areas of knowledge.
In 1946, a 20-year-old employee of the Patent Department of the Soviet Navy, a former military pilot and by this time already an experienced inventor Lieutenant Heinrich Altshuller started development of the Theory of Inventive Problem Solving (TRIZ)1 The main ideas of classical TRIZ:
- Selection and analysis of the inventive problem (mini-problem) and the system with which the problem is associated, using a set of procedures, questions and recommendations that represent (in contrast to the known checklists) a recursive multi-step algorithm of the inventor’s actions. This algorithm includes:
– In-depth study of the system, and of resources necessary to solve the problem and available in the system itself or in its environment
– Formulation of the ultimate goal of the solution in the form of an Ideal Ultimate Result (IUR)
– Formulation and resolution of a contradiction that prevents resolving the problem
– Formulation of solution ideas at various stages of problem-solving process (most often – after identifying IUR and Contradiction)
– Further strengthening and development of the solution ideas
- The use of preliminary structured databases, including:
– Set of operators (inventive problem-solving techniques), guiding inventor’s thinking in the most promising direction.
– Menu system, for example, in a table form, allowing one to select the most promising operators for a specific task.
– Set of examples of effective inventions, illustrating the use of operators and create helpful analogies and associations.
– Set of patterns and sub-patterns that predict the most promising directions for system development.
- Creative thinking development, during and after training, including:
– Solving a significant number and variety of educational inventive problems.
– Solving real problems under the supervision and if necessary with the help of a TRIZ-certified instructor
– Using the methods of Development of Creative Imagination.
(1) Initial name – Method of Invention, next development – Algorithm for Solving Inventive Problems (ARIZ). In the late seventies the method received the name TRIZ. Today there is a distinction between Classical TRIZ, developed mainly by Altshuller and advanced Modern TRIZ, developed by Altshuller students and followers.
