What is TRIZ? The Systematic Way to Invent
TRIZ turns invention from guesswork into a repeatable method. Here is how it works and why engineers should care.
TRIZ — the Theory of Inventive Problem Solving — is a systematic method developed by Genrich Altshuller from the analysis of millions of patents. Instead of brainstorming randomly, TRIZ gives engineers a repeatable path to breakthrough solutions.
The core idea
TRIZ is built on the observation that most inventions resolve a technical contradiction — improving one parameter worsens another. TRIZ provides 40 inventive principles and a contradiction matrix to find proven solutions instead of reinventing them.
- Identify the contradiction you are trying to solve
- Use the contradiction matrix to map it to relevant principles
- Apply the inventive principles that fit your context
- Evolve the design toward the ideal final result
For KED, TRIZ turns a vague problem into a short list of directions worth exploring — faster and more focused than guesswork.
