Name the contradiction at the heart of the problem
State exactly which parameter you need to improve and which parameter gets worse as a result.
Key takeaways
- What it is: State exactly which parameter you need to improve and which parameter gets worse as a result.
- Why it works: TRIZ distinguishes "technical contradictions" (improving A worsens B) from "physical contradictions" (a parameter must be both X and not-X at the same time). Naming the contradiction precisely does two things: it prevents pseudo-solutions that optimize one side at the other’s expense, and it lets you consult TRIZ’s contradiction matrix to find which inventive principles have historically resolved that specific trade-off. The act of articulating the contradiction often reveals that the trade-off was assumed rather than fundamental.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Describing the contradiction vaguely ("it’s too slow and too expensive") rather than naming the specific parameters and their directional relationship, which makes the TRIZ matrix unusable.
Why it works
TRIZ distinguishes "technical contradictions" (improving A worsens B) from "physical contradictions" (a parameter must be both X and not-X at the same time). Naming the contradiction precisely does two things: it prevents pseudo-solutions that optimize one side at the other’s expense, and it lets you consult TRIZ’s contradiction matrix to find which inventive principles have historically resolved that specific trade-off. The act of articulating the contradiction often reveals that the trade-off was assumed rather than fundamental.
How to do it
- 1State what you want to improve (e.g., strength of a component).
- 2State what gets worse when you do that (e.g., weight of the component).
- 3Write: "If I improve [X], then [Y] gets worse. I need [X] to increase AND [Y] not to worsen."
- 4Check if this is a physical contradiction: "I need [X] to be both high and low (or present and absent)."
- 5Use this framing as the input to any inventive-principle lookup or creative session.
What the evidence says
ObservationalContradiction identification is the foundational move in TRIZ. Altshuller’s patent analysis showed that most non-trivial inventions resolve a contradiction rather than accept it. This is practitioner-derived and observational; controlled comparisons against other problem-framing methods are not established.
Honest caveat: TRIZ was developed primarily in engineering contexts; transferring it to organizational or personal problems requires translation, and the contradiction framing can feel forced for non-technical domains.
Common mistake
Describing the contradiction vaguely ("it’s too slow and too expensive") rather than naming the specific parameters and their directional relationship, which makes the TRIZ matrix unusable.
