morphological-analysis-triz

name: morphological-analysis-triz description: Explores solution spaces systematically through morphological analysis (parameter-option matrices) and resolves technical contradictions using TRIZ inventive principles to generate novel, non-obvious solutions. Use when exploring all feasible design alternatives before prototyping, resolving technical contradictions (speed vs precision, strength vs weight, cost vs quality), generating novel product configurations, finding inventive solutions to engineering problems, identifying patent opportunities, or when user mentions morphological analysis, Zwicky box, TRIZ, inventive principles, systematic innovation, or design space exploration.

Morphological Analysis & TRIZ

Workflow

Copy this checklist:

Morphological Analysis & TRIZ Progress:
- [ ] Step 1: Define problem and objectives
- [ ] Step 2: Choose method (MA, TRIZ, or both)
- [ ] Step 3: Build morphological box (if MA)
- [ ] Step 4: Identify contradictions (if TRIZ)
- [ ] Step 5: Apply TRIZ principles
- [ ] Step 6: Evaluate and select solutions

Step 1: Define problem and objectives

Clarify problem statement, key objectives, constraints (cost, size, time, materials), and success criteria.

Step 2: Choose method

• Morphological Analysis: 3-7 clear parameters, each with 2-5 options, goal is comprehensive exploration
• TRIZ: Clear contradiction (improving A worsens B), need inventive breakthrough
• Both: Complex system with parameters AND contradictions

Step 3: Build morphological box (if using MA)

1. Identify 3-7 independent parameters (changing one doesn't force another)
2. List 2-5 distinct options per parameter
3. Create parameter × option matrix

See resources/template.md for structure.

Step 4: Identify contradictions (if using TRIZ)

State clearly:

• Improving parameter: What to increase?
• Worsening parameter: What degrades?
• Look up in TRIZ contradiction matrix

See resources/template.md for 39 TRIZ parameters and contradiction matrix.

Step 5: Apply TRIZ principles

1. Review 3-4 principles recommended by matrix
2. Brainstorm applications of each principle
3. Generate solution concepts
4. Combine principles for stronger solutions

See resources/template.md for all 40 principles.

For advanced techniques, see resources/methodology.md.

Step 6: Evaluate and select

Morphological: Identify promising combinations, eliminate infeasible, score on objectives, select top 3-5

TRIZ: Assess contradiction resolution, check side effects, estimate difficulty, select most promising

Use resources/evaluators/rubric_morphological_analysis_triz.json for quality criteria.

Common Patterns

Typical Parameters (Examples)

Physical Products: Materials, power source, form factor, control interface, manufacturing method Software: Architecture, data storage, UI, deployment, authentication Services: Delivery channel, pricing model, timing, customization, support level Processes: Automation level, batch size, quality control, scheduling, location

Common Contradictions

Full principles list: See resources/template.md for all 40.

When to Combine MA + TRIZ

1. Build morphological box → Find promising configurations
2. Identify contradictions in top configurations
3. Apply TRIZ to resolve contradictions
4. Re-evaluate configurations with contradictions resolved

Guardrails

Morphological Analysis:

• Limit parameters: 3-7 parameters (too few = incomplete, too many = explosion)
• Ensure independence: Changing one parameter shouldn't force changes in another
• Manageable options: 2-5 per parameter (practical range)
• Don't enumerate all: Focus on promising clusters

TRIZ:

• Verify real contradiction: Improving A truly worsens B (not just budget limit)
• Adapt principles: Use as metaphors, not literal prescriptions
• Check new contradictions: Solution may introduce new trade-offs
• Combine principles: Often need 2-3 together

General:

• Document rationale for parameters/options selected
• Iterate if first pass reveals missing dimensions
• Prototype top concepts - don't just analyze

Quick Reference

Resources:

• resources/template.md - Morphological structure, TRIZ contradiction matrix, 40 principles
• resources/methodology.md - Advanced TRIZ (trends of evolution, substance-field, ARIZ algorithm)
• resources/evaluators/rubric_morphological_analysis_triz.json - Quality criteria

Output: morphological-analysis-triz.md with problem definition, morphological matrix (if used), contradictions, TRIZ principles applied, solution concepts, evaluation, selected solutions

Success Criteria:

• Parameters independent and essential (3-7 with 2-5 options each)
• Contradictions clearly stated (improving/worsening parameters)
• Multiple principles applied per contradiction
• Solutions are novel, feasible, address objectives
• Top 3-5 selected with rationale
• Score ≥ 3.5 on rubric

Quick Decisions:

• Simple configuration? → Morphological only
• Clear contradiction? → TRIZ only
• Complex with trade-offs? → Both methods
• Unsure? → Start TRIZ to identify contradictions, then build morphological box

Common Mistakes:

1. Too many parameters (>7 = explosion)
2. Dependent parameters (choosing A forces B)
3. Vague contradiction ("better vs cheaper" - be specific)
4. Literal TRIZ (principles are metaphors)
5. No evaluation (generate but don't filter)

Examples:

Morphological (Portable Speaker):

Power: Battery | Solar | Hybrid
Size: Pocket | Handheld | Tabletop
Audio: Mono | Stereo | Surround
Material: Plastic | Metal | Fabric
Control: Button | Touch | Voice | App
Result: 3×3×3×4×4 = 432 configs → Evaluate top 10

TRIZ (Electric Vehicle Range):

Contradiction: Increase range → worsens cost (battery expensive)
Principles: #6 (Universality - battery is structure), #35 (Parameter change - new chemistry)
Solution: Structural battery pack + high energy density cells

Combined:

Build morphological box for EV architecture → Top config has range/cost contradiction → Apply TRIZ Universality principle → Structural battery resolves both range and cost
