What Is It

基本介绍

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.
包含两种互补的方法:
形态分析: 将问题拆解为多个参数,识别每个参数的可选值,通过系统组合探索解决方案空间。
参数:功率(3个选项) × 尺寸(4个选项) × 材质(3个选项) = 36种配置
TRIZ: 利用40条创造性原理解决矛盾。例如:「提升速度→降低精度」的矛盾可通过原理#1(分割)解决:快速粗加工+慢速精加工。

Workflow

工作流程

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

Guardrails

使用准则

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
形态分析:
  • 限制参数数量: 3-7个参数为宜(太少→探索不全面,太多→组合爆炸)
  • 确保参数独立: 修改一个参数不会强制改变其他参数
  • 控制选项数量: 每个参数2-5个选项(合理范围)
  • 无需枚举所有组合: 重点关注有潜力的组合集群
TRIZ:
  • 验证矛盾真实性: 优化A确实会劣化B(而非只是预算限制等人为约束)
  • 灵活适配原理: 原理是参考隐喻,而非字面的硬性规定
  • 检查新矛盾: 解决方案可能引入新的权衡问题
  • 组合使用原理: 通常需要同时应用2-3条原理
通用准则:
  • 记录选择参数/选项的逻辑依据
  • 如果首轮探索发现遗漏维度,可迭代优化
  • 对顶级概念进行原型验证-不要停留在分析阶段

Quick Reference

快速参考

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

输出物:
morphological-analysis-triz.md
,包含问题定义、形态矩阵(若使用)、矛盾、应用的TRIZ原理、解决方案概念、评估结果、选定的解决方案
成功标准:
  • 参数独立且核心(3-7个参数,每个2-5个选项)
  • 矛盾描述清晰(明确优化/劣化参数)
  • 每个矛盾应用多条原理
  • 方案新颖、可行、符合目标
  • 选定前3-5个方案并说明依据
  • 评估 rubric 得分≥3.5
快速决策:
  • 简单配置场景? → 仅用形态分析
  • 存在明确矛盾? → 仅用TRIZ
  • 复杂且有权衡问题? → 两种方法结合
  • 不确定? → 先用TRIZ识别矛盾,再构建形态盒
常见错误:
  1. 参数过多(>7个会导致组合爆炸)
  2. 参数不独立(选择A会强制选择B)
  3. 矛盾描述模糊(「更好vs更便宜」,需要具体化)
  4. 死板套用TRIZ(原理是隐喻,不是硬性规则)
  5. 缺少评估环节(只生成方案不筛选)
示例:
形态分析(便携式音箱):
电源:电池 | 太阳能 | 混合供电
尺寸:口袋款 | 手持款 | 桌面款
音频:单声道 | 立体声 | 环绕声
材质:塑料 | 金属 | 织物
控制方式:按键 | 触控 | 语音 | APP
结果:3×3×3×4×4 = 432种配置 → 评估前10名
TRIZ(电动车续航):
矛盾:提升续航→劣化成本(电池成本高)
原理:#6(通用性 - 电池同时作为结构件)、#35(参数变化 - 新化学体系)
解决方案:结构电池组+高能量密度电芯
结合使用示例:
为电动车架构构建形态盒→顶级配置存在续航/成本矛盾→应用TRIZ通用性原理→结构电池同时解决续航和成本问题
