The TRIZ Process One of the Altshuller's condition for TRIZ is to be familiar enough to inventors by following the general approach to problem solving. A model was constructed as below.
The TRIZ Process
Step 1. Identifying My Problem: There is a standard questionnaire called "Innovative Situation Questionnaire" (ISQ) (developed by Zlotin and Zusman) to identify the system being studied, its operating environment, resource requirements, primary useful function, harmful effects, and ideal result. Step 2. Formulate the problem: The Prism of TRIZ: Restate the problem in terms of physical contradictions, identify problems that could occur. Could improving one technical characteristic to solve a problem cause other technical characteristics to worsen, resulting in some other problems arising? Are there technical conflicts that might force a trade-off? Step 3. Search for Previously Well-Solved Problem: Altshuller extracted from over 1.500.000 patents 39 standard technical characteristics that cause conflict. These are called 39 engineering parameters. Find the contradicting engineering principles. First find the principle that needs to be changed, then find the principle that is an undesirable secondary effect. State the standard technical conflict. Step 4. Look for Analogous Solutions and Adapt to My Solution: Altshuller also extracted from the world wide patents 40 inventive principles. These are hints that will help an engineer find a highly inventive solution to the problem. To find which inventive principles to use, look at the Table of Contradictions (also created by Altshuller). The Table of Contradictions lists the 39 engineering parameters on the X-axis (undesired secondary effect) and Y-axis (feature to improve). In the intersecting cells, are listed the appropriate Inventive Principles to use for a solution.
