Problem Routing
| Problem Type | Tool | Reference |
|---|---|---|
| "Improve A but B worsens" | Contradiction Matrix | 40-principles.md |
| "Need opposite properties" | Separation Principles | Below |
| "System not working" | Su-Field Analysis | advanced.md |
| "How will tech evolve?" | Evolution Trends | advanced.md |
| "What do others do?" | FOS (cross-industry) | ai-prompts.md |
| "Very complex problem" | ARIZ Algorithm | ai-prompts.md |
6-Step Process
1. DEFINE IFR → "The [system] ITSELF [does X] WITHOUT [cost/harm]"
2. IDENTIFY → What contradiction? (Technical or Physical)
3. MAP → Which of 39 parameters? [39-parameters.md]
4. RETRIEVE → Matrix suggests which principles?
5. GENERATE → Apply each principle specifically
6. EVALUATE → Feasibility? Implementation?
Step 1: Ideal Final Result (IFR)
"The [object] ITSELF [performs function] WITHOUT [cost/harm/complexity]"
Formula: Ideality = Benefits / (Cost + Harm)
Examples:
- "The pipe itself prevents leaks" (not: add sensors)
- "The code itself fixes bugs" (not: add more tests)
Step 2: Identify Contradiction
Technical: Improving A worsens B
"If we [improve A], then [B gets worse]"
→ ถ้าเราทำให้รถเร็วขึ้น, ประสิทธิภาพน้ำมันแย่ลง
Physical: Same element needs opposite properties
"[Element] must be [Property] for X AND [Opposite] for Y"
→ API ต้อง complex (power users) AND simple (beginners)
Step 3: Map to 39 Parameters
See 39-parameters.md. Common ones:
| # | Parameter | Software Equivalent |
|---|---|---|
| 9 | Speed | Performance, latency |
| 27 | Reliability | Uptime, MTBF |
| 33 | Ease of operation | UX, usability |
| 36 | Complexity | Code complexity |
| 39 | Productivity | Throughput |
Step 4: Top 10 Principles
| # | Principle | Modern Example |
|---|---|---|
| 1 | Segmentation | Microservices |
| 2 | Taking Out | Separation of concerns |
| 10 | Preliminary Action | Caching |
| 13 | The Other Way Round | Event-driven vs polling |
| 15 | Dynamics | Adaptive algorithms |
| 24 | Intermediary | Middleware, adapters |
| 25 | Self-Service | Self-healing systems |
| 35 | Parameter Changes | Transform data format |

Step 5: Physical Contradiction → Separation
| Separation | Strategy | Example |
|---|---|---|
| In Time | Different times | Landing gear: extend/retract |
| In Space | Different locations | Pencil: hard core, soft eraser |
| In Condition | Different conditions | Smart glass: transparent/opaque |
| In Scale | Different levels | Water: liquid macro, molecules nano |
Creative Mode: FOS/MOS
Function Oriented Search (FOS): Find how OTHER industries solve same function.
1. ABSTRACT → "Remove ice" → "Separate materials"
2. SEARCH → Find 5+ industries with similar function
3. TRANSFER → Adapt mechanism to your problem
Method Oriented Search (MOS): Apply known method to NEW domains.
See ai-prompts.md for detailed prompts.
