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

Full list: 40-principles.md

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.
