Contradiction Matrix" in TRIZ with Application | K.M.Eazhil | SNSInstitutions

Improving a Production Line

Scenario: A manufacturing company faces a challenge where increasing production speed results in higher defect rates in their products.

Step 1: Define the Contradiction

• Improvement Goal: Increase production speed (Parameter A).
• Deterioration Issue: Higher defect rates (Parameter B).

Step 2: Locate Parameters on the Matrix

In this case, "Production Speed" and "Product Quality" are identified as conflicting parameters.

Step 3: Consult the Contradiction Matrix

The team finds that at the intersection of these parameters, several inventive principles are suggested, such as:

• Principle 1 (Segmentation): Break down tasks into smaller segments that can be performed simultaneously by different workers or machines.
• Principle 10 (Preliminary Anti-Action): Implement quality checks before defects occur, such as using sensors to detect potential issues before products leave the assembly line.

Step 4: Implement Solutions

The manufacturing team decides to:

• Introduce parallel processing where multiple assembly lines operate simultaneously at different speeds tailored to specific product types.
• Install real-time monitoring systems that alert operators to potential quality issues before products are finished.

Benefits of Using the Contradiction Matrix

• Structured Problem Solving: Provides a clear framework for addressing complex engineering challenges.
• Encourages Innovation: By suggesting proven inventive principles, it fosters creative thinking and solution development.
• Cross-Industry Insights: Leverages knowledge from various fields, allowing manufacturers to apply solutions that have worked elsewhere.

The Contradiction Matrix is an essential tool within TRIZ that helps manufacturers systematically resolve conflicts between competing objectives. By applying this methodology, organizations can enhance their innovation capabilities, improve product quality, and streamline production processes effectively.
