TRIZ is a method of inventive problem solving that relies on 40 principles to resolve
contradictions in design. Contradictions in design occur when the improvement of one
characteristic in a system causes the deterioration of another characteristic.
The TRIZ Technical Contradictions Matrix
answers the following questions.
- Which features might improve?
- Which features might worsen?
- What are some examples of each principle?
- Which principles apply to my scenario?
- Identify the contradiction. For example, you want to install ordering kiosks
in a popular coffee shop to improve wait time.
- From Improving Feature, select the principle responsible for the improvement. In this example,
wait time is related to the principle of speed.
- From Worsening Feature, select the principle responsible for the corresponding degradation. In
this example, the electronic kiosk is related to the principle of device
- After you select the features, the Recommended Principles table returns four principle-ID combinations based on the contradictory
features you selected in the previous step.
- Under The 40 TRIZ Inventive
Principles, select the arrow to see
examples of each principle-ID combination.
- Select the check mark to open the
matrix. Use the IDs in My Results to find the features to improve, in the rows, and the features that might
degrade, in the columns.
- Use the information in the matrix to resolve the contradiction you
