Su-Field Analysis
Overview
Su-Field (Substance-Field) Analysis models technical systems as interactions between substances and fields.
Basic Structure
A minimal working system requires 3 elements:
F (Field)
↓
S1 ←—————→ S2
(Tool) (Object)
- S1: Tool (the acting substance)
- S2: Object (the substance being acted upon)
- F: Field (the energy/means of interaction)
Types of Fields
| Field Type | Examples |
|---|---|
| Mechanical | Force, pressure, vibration, acoustic |
| Thermal | Heat, cold |
| Chemical | Reactions, catalysis |
| Electrical | Current, charge |
| Magnetic | Magnetism, electromagnetic |
| Optical | Light, laser |
| Gravitational | Weight, centrifugal |
Problem Models
| Model Type | Description | Solution Direction |
|---|---|---|
| Incomplete | Missing S1, S2, or F | Add missing element |
| Insufficient | System works poorly | Improve/modify elements |
| Harmful | Unwanted interaction | Block/eliminate harm |
Incomplete Su-Field
Problem: System has only 1-2 elements.
Missing F: S1 .... S2 → Add a field
Missing S: F → S1 → Add a tool substance
Solution: Complete the Su-Field by adding missing element.
Insufficient Su-Field
Problem: Interaction is weak or ineffective.
Solutions:
- Replace F with stronger field
- Add another field (F2)
- Modify S1 or S2
- Add ferromagnetic particles + magnetic field
Harmful Su-Field
Problem: Unwanted harmful effect exists.
F (harmful)
↓
S1 ←——×——→ S2
Solutions:
- Insert S3 between S1 and S2
- Add F2 to counteract harmful F
- Modify S1 or S2 to be unaffected
- Eliminate source of harm

ARIZ Algorithm
Overview
ARIZ (Algorithm of Inventive Problem Solving) is the most powerful TRIZ tool for complex problems. Current version: ARIZ-85C.
When to Use
- 85% of problems can be solved with simpler tools
- Use ARIZ for remaining 15% (most complex problems)
- Use when Contradiction Matrix doesn't provide solution
The 9 Parts of ARIZ
Part 1: Problem Analysis
- Define the mini-problem
- Identify conflicting elements
- Make graphical models
- Choose a conflict (if multiple)
Part 2: Problem Model Analysis
- Identify operational zone

Part 3: Ideal Final Result (IFR)
- Formulate IFR: "X-element, without complicating the system, eliminates [harm] while maintaining [useful action]"
- Intensify the formulation
- Define physical contradiction
Part 4: Mobilizing Resources

Key ARIZ Concepts
Mini-Problem: Simplify by keeping existing system, just eliminate deficiency.
Physical Contradiction Intensification:
- Must be [Property] to do X
- Must be [Opposite Property] to do Y
- Make properties as extreme as possible
Separation Principles:
- In time
- In space
- In condition
- In scale/level
Evolution Trends
Overview
Technical systems evolve following predictable patterns. Use these to forecast and guide innovation.
The 8 Laws of Technical System Evolution
1. S-Curve Stages
All technologies follow 4 stages:
Performance
↑
| ╭────── Maturity/Decline
| ╱
| ╱ Growth
| ╱
| ╱
| ╱ Infancy
+─────────────────→ Time
| Stage | Characteristics | Strategy |
|---|---|---|
| Infancy | Low performance, high invention rate | Invest in R&D |
| Growth | Rapid improvement | Scale up |
| Maturity | Plateau, optimization | Efficiency focus |
| Decline | New tech emerges | Transition/exit |
2. Increasing Ideality
Systems evolve toward higher ideality:
Ideality = (Sum of Benefits) / (Sum of Cost + Harm)
Ultimate: Ideal system doesn't exist, but function is delivered.
3. Non-Uniform Development of Parts
Different parts evolve at different rates. Weakest parts limit system performance.
Action: Identify and improve limiting subsystems.
4. Increasing Dynamism and Controllability
Evolution path:
Rigid → Jointed → Flexible → Fluid → Field-based
Examples:
- Solid → hinged → bendable → liquid → electromagnetic
- Manual → semi-auto → automatic → AI-controlled
5. Increasing Complexity Then Simplification
Simple → Complex → Simplified (integrated)
First: add functions/parts Then: integrate, trim, optimize
6. Matching and Mismatching Parts
Parts must match for efficient energy transfer. Deliberately mismatch for new effects.
7. Transition to Micro-Level
Macro → Micro → Nano → Field
Examples:
- Mechanical switches → transistors → molecular switches
- Bulk materials → particles → molecules → fields
8. Increasing Human Involvement Then Reduction
Manual → Tool-aided → Mechanized → Automated → Autonomous
Additional Evolution Trends
| Trend | From → To |
|---|---|
| Segmentation | Monolithic → Segmented → Powder → Field |
| Surface | Flat → 3D texture → Active surface |
| Symmetry | Symmetric → Asymmetric → Optimized |
| Nesting | Single → Nested → Multi-nested |
| Coordination | Uncoordinated → Resonant → Optimized |
| Action | Continuous → Periodic → Optimized pattern |
| Control | Open loop → Feedback → Feedforward |
Using Evolution Trends
- Locate current position on evolution curves
- Identify next step from trends
- Generate ideas using suggested direction
- Combine trends for breakthrough innovation
Example: Mobile Phone Evolution
| Trend | Past | Present | Future |
|---|---|---|---|
| Dynamism | Fixed → Portable | Flexible screens | Rollable/foldable |
| Micro-level | Analog → Digital | Nano processors | Quantum? |
| Ideality | Multiple devices | Smartphone | Wearable/invisible |
