TRIZ Contradiction Matrix and Inventive Principles Toolv1.1.0

Resolve design trade-offs systematically using the Theory of Inventive Problem Solving (TRIZ), developed by Genrich Altshuller from the analysis of more than 40,000 patents. Use this tool to map common engineering contradictions to proven solution strategies called inventive principles, replacing trial-and-error brainstorming with a structured framework relied on by engineers, designers, product managers, and innovators.

• Select Contradiction Matrix mode to resolve a specific trade-off between two engineering parameters. Pick a preset from the Common Contradictions dropdown to jump to a famous trade-off, or choose your own pair from the Improving and Worsening dropdowns. Click Find Principles (or just change the dropdowns) to see the recommended inventive principles.
• Select Browse All 40 Principles mode to review every TRIZ inventive principle with its description and sub-principles. Each principle has a collapsible details panel so you can expand only the ones you want to read.
• Select Search Principles mode to find principles by keyword. Type a term such as "vibration", "thermal", or "composite" and press Enter or click Search. Matches are ranked: hits in the principle name rank above hits in the description, which rank above hits in sub-principles, with the matched text highlighted.
• If a contradiction has no canonical recommendation, the tool computes soft suggestions from neighboring cells in the matrix so you still have a starting point.
• Each result lists a reciprocal button to flip the trade-off (improving Y without worsening X) and explore the contradiction from the opposite direction.
• Click any parameter name in a result to see all contradictions involving that parameter, as either improving or worsening.
• Export results from any contradiction panel: Copy as Markdown or Copy as Plain Text sends formatted output to the clipboard, while Save as Markdown or Save as Plain Text downloads a file named after the parameter pair (for example, triz-strength-vs-weight-moving.md or, for soft suggestions, triz-soft-strength-vs-weight-moving.txt).
• Use Settings to toggle whether principle descriptions appear and whether sub-principles open by default. Use Reset to clear all selections and return to defaults.

Apply the TRIZ methodology across industries whenever a design improvement in one area causes degradation in another. The following scenarios illustrate practical applications of the contradiction matrix and inventive principles.

• Mechanical Engineering: Resolve the contradiction between increasing the strength of a structural component while reducing its weight. The matrix may recommend principles such as Composite Materials, Preliminary Action, or Dynamics to guide the design toward lightweight high-strength solutions.
• Product Design: Address the trade-off between improving the ease of manufacturing a consumer device and increasing its reliability. Principles such as Segmentation, Universality, or Nesting can suggest novel design approaches that satisfy both objectives.
• Software Engineering: Apply TRIZ thinking to resolve contradictions between system speed and accuracy, or between feature richness and ease of use. Principles like Partial or Excessive Action, Another Dimension, or Dynamics translate well into software architecture decisions.
• Education: Teach students systematic problem-solving methods by having them identify contradictions in case studies and look up recommended principles. The browse and search modes make the 40 principles accessible for classroom exercises and homework assignments.
• Manufacturing: Optimize production processes where increasing throughput degrades product quality. The contradiction matrix points to principles such as Periodic Action, Continuity of Useful Action, or Parameter Changes that have resolved similar contradictions across thousands of patented inventions.
• Research and Development: During early-stage ideation, use the full list of 40 principles as a creativity checklist to ensure the team has considered all proven solution strategies before committing to a design direction.
• Patent Analysis: Compare existing patents against TRIZ principles to identify which inventive strategies have already been applied to a contradiction and which remain unexplored for a given parameter pair.
