Purpose

Systematically explore solution spaces through morphological analysis (parameter-option matrices) and resolve technical contradictions using TRIZ inventive principles to generate novel, non-obvious solutions.

When to Use

Systematic Exploration:

• Explore all feasible configurations before committing
• Generate comprehensive set of design alternatives
• Create product line variations across parameters
• Document complete solution space

Innovation & Invention:

• Find novel, non-obvious solutions
• Generate patentable innovations
• Discover synergies between features
• Break out of conventional thinking

Resolving Contradictions:

• Improve one parameter without worsening another
• Solve "impossible" trade-offs (faster AND cheaper)
• Apply proven inventive principles
• Resolve conflicts between requirements

Engineering & Design:

• Design new products/systems from scratch
• Optimize existing designs systematically
• Configure complex systems with many parameters

What Is It

Two complementary methods:

Morphological Analysis: Decompose problem into parameters, identify options for each, systematically combine to explore solution space.

Parameters: Power (3 options) × Size (4 options) × Material (3 options) = 36 configurations

TRIZ: Resolve contradictions using 40 inventive principles. Example: "Improve speed → worsens precision" solved by Principle #1 (Segmentation): fast rough pass + slow precision pass.

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

Improving ↑	Worsens ↓	Example TRIZ Principles
Speed	Precision	Segmentation, Periodic action
Strength	Weight	Anti-weight, Composite materials
Reliability	Complexity	Segmentation, Beforehand cushioning
Functionality	Ease of use	Segmentation, Universality
Capacity	Size	Nesting, Another dimension

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
