triz-solver

name: triz-solver description: "Apply TRIZ inventive principles to solve problems that seem to have no good solution. Use after triz-analysis has identified contradictions."

TRIZ Solver

When to Use

• After completing TRIZ analysis (triz-analysis skill)
• When standard solutions don't work
• When tradeoffs seem unavoidable
• For creative problem-solving in architecture

Process

1. Review Contradictions

Load contradictions identified in plans/triz/ analysis.

2. Select Primary Principle

From references/principles.md (via triz-analysis), choose the most applicable principle.

3. Apply the Principle

Follow the principle's specific technique:

Segmentation (#1)

• Split the problem into independent parts
• Apply different solutions to each part
• Example: Different search strategies for different query sizes

Taking out (#2)

• Extract the problematic element
• Keep only essential functionality
• Example: Extract rate limiting to middleware

Inversion (#12)

• Reverse the control flow
• Example: IoC container, dependency injection

Feedback (#23)

• Add feedback loops
• Example: Auto-tuning based on metrics

Composite Materials (#40)

• Combine multiple approaches
• Example: Hybrid keyword + semantic search

4. Validate Solution

Check against IFR:

• Does it move toward the ideal?
• Does it resolve the contradiction?
• Are there new problems introduced?

5. Document Resolution

Update plans/triz/ with:

• Chosen principle(s)
• Implementation approach
• Tradeoffs accepted
• Validation results

Solution Patterns

Pattern: Strategy Segmentation

When: Performance varies by input characteristics Apply: Principle #1 (Segmentation) + #3 (Local quality) Solution: Dispatch table routing to specialized handlers

Pattern: Inverted Control

When: Flexibility creates complexity Apply: Principle #12 (Inversion) Solution: DI container with declarative wiring

Pattern: Composite Approach

When: Single approach has fatal flaw Apply: Principle #40 (Composite) Solution: Combine approaches, use best of each

Pattern: Preliminary Action

When: Runtime costs are high Apply: Principle #10 (Preliminary action) Solution: Pre-compute, cache, or compile at build time

Pattern: Feedback Loop

When: Static solution is suboptimal Apply: Principle #23 (Feedback) Solution: Adaptive algorithm with runtime adjustment

Anti-Patterns to Avoid

1. Applying principle superficially: Don't just rename, restructure
2. Ignoring IFR: Keep the ideal as the goal
3. Accepting tradeoffs too early: Principles resolve contradictions
4. Single principle fixation: Combine 2-3 principles for complex problems

Example Session

Problem: Retrieval pipeline has slow cold starts but caching adds complexity.

IFR: Pipeline warms itself without explicit cache management.

Contradiction: Speed vs Simplicity

Principles Applied:
- #25 Self-service: Cache populates on first access
- #23 Feedback: Track access patterns
- #15 Dynamicity: Adjust caching based on patterns

Solution: Lazy population with adaptive eviction based on access frequency.
