## 1. Trends of Technical Evolution
### Concept
Technical systems evolve along predictable patterns. Understanding these trends helps predict future states and design next-generation solutions.
### 8 Key Trends
**Trend 1: Mono-Bi-Poly (Increasing Complexity Then Simplification)**
- Mono: Single system
- Bi: System + counteracting system
- Poly: Multiple interacting systems
- Then: Integration/simplification
**Example:**
- Mono: Manual transmission (single system)
- Bi: Manual + automatic (two options)
- Poly: CVT, dual-clutch, automated manual (many variants)
- Integration: Seamless hybrid transmission
**Application:** If stuck at Bi-Poly stage, look for integration opportunities
**Trend 2: Transition to Micro-Level**
- Macro → Meso → Micro → Nano
- System operates at smaller scales over time
**Example:**
- Macro: Room air conditioner
- Meso: Window unit
- Micro: Personal cooling device
- Nano: Fabric with cooling nanoparticles
**Application:** Can your solution work at smaller scale?
**Trend 3: Increasing Dynamism & Controllability**
- Fixed → Adjustable → Adaptive → Self-regulating
**Example:**
- Fixed: Solid chair
- Adjustable: Height-adjustable chair
- Adaptive: Chair that conforms to posture
- Self-regulating: Chair that actively prevents back pain
**Application:** Add adjustability, then feedback control, then autonomous adaptation
**Trend 4: Increasing Ideality (IFR - Ideal Final Result)**
- System delivers more benefits with fewer costs and harms
- Ultimate: All benefits, no cost/harm (ideal is unattainable but directional)
**Formula:** Ideality = Σ(Benefits) / [Σ(Costs) + Σ(Harms)]
**Application:** Systematically increase numerator (add benefits) and decrease denominator (remove costs/harms)
**Trend 5: Non-Uniform Development**
- Different parts evolve at different rates → contradictions emerge
- Advanced subsystem bottlenecked by primitive subsystem
**Example:** High-performance engine limited by weak transmission
**Application:** Identify lagging subsystems and bring them to parity
**Trend 6: Transition to Super-System**
- Individual system → System + complementary systems → Integrated super-system
**Example:**
- Computer alone
- Computer + printer + scanner (separate)
- All-in-one device (integrated super-system)
**Application:** What complementary systems can be integrated?
**Trend 7: Matching/Mismatching**
- Matching: All parts work in coordination (efficiency)
- Mismatching: Deliberate asymmetry for specific function
**Example:** Matched: All wheels same size (car). Mismatched: Different front/rear tires (drag racer)
**Application:** Sometimes deliberate mismatch creates new capabilities
**Trend 8: Increasing Use of Fields**
- Mechanical → Thermal → Chemical → Electric → Magnetic → Electromagnetic
**Example:**
- Mechanical: Manual saw
- Thermal: Hot wire cutter
- Electric: Powered saw
- Magnetic: Magnetic coupling
- Electromagnetic: Laser cutter
**Application:** Can you replace mechanical action with a "higher" field?
### How to Apply Trends
**Step 1:** Identify where current system is on each trend
**Step 2:** Predict next stage in evolution
**Step 3:** Design solution that leapfrogs to next stage
**Step 4:** Look for contradictions that arise and resolve with TRIZ principles

## 2. Substance-Field Analysis
### Concept
Model systems as interactions between substances (S1, S2) and fields (F) to identify incomplete or harmful models and transform them.
### Basic Model: S1 - F - S2
- **S1:** Object being acted upon (workpiece, patient, user)
- **F:** Field providing energy (mechanical, thermal, chemical, electrical, magnetic)
- **S2:** Tool/agent acting on S1 (cutter, heater, medicine, interface)
### Complete vs Incomplete Models
**Incomplete (Doesn't work well):**
```
S1 ---- S2 (No field, or field too weak)
```
**Solution:** Add or strengthen field
**Complete (Works):**
```
S1 <-F-> S2 (Field connects substances effectively)
```
### 76 Standard Solutions
TRIZ catalogs 76 standard substance-field transformations. Key examples:
**Problem: Incomplete model (S1 and S2 not interacting)**
- **Solution 1:** Add field F between them
- **Solution 2:** Replace S2 with more reactive substance S3
- **Solution 3:** Add substance S3 as intermediary
**Problem: Harmful action (field F causes unwanted effect)**
- **Solution 1:** Insert substance S3 to block harmful field
- **Solution 2:** Add field F2 to counteract F1
- **Solution 3:** Remove or modify S2 to eliminate harmful field
**Problem: Need to detect or measure S1 (invisible, inaccessible)**
- **Solution 1:** Add marker substance S3 that reveals S1
- **Solution 2:** Use external field F2 to probe S1
- **Solution 3:** Transform S1 into S1' that's easier to detect
### Application Example
**Problem:** Need to inspect internal pipe for cracks (S1 = pipe, can't see inside)
**Substance-field analysis:**
```
Current: S1 (pipe) - no effective field - S2 (inspector)
Incomplete model
```
**Solutions via standard models:**
1. Add ferromagnetic particles + magnetic field (field F reveals cracks)
2. Add ultrasonic field (detect reflection changes at cracks)
3. Add pressurized dye penetrant (substance S3 reveals cracks)
**Selected:** Magnetic particle inspection (proven technique)

## 3. ARIZ Algorithm
### Concept
ARIZ (Algorithm of Inventive Problem Solving) is systematic step-by-step process for complex problems where contradiction isn't obvious.
### ARIZ Steps (Simplified)
**Step 1: Problem Formulation**
- State problem as given
- Identify ultimate goal
- List available resources (time, space, substances, fields, information)
**Step 2: Mini-Problem**
- Define "ideal final result" (IFR): system achieves goal with minimal change
- Formulate mini-problem: "Element X, using available resources, must provide [desired effect] without [harmful effect]"
**Step 3: Physical Contradiction**
- Identify conflicting requirements on single element
- Example: "Element must be hard (for strength) AND soft (for flexibility)"
**Step 4: Separate Contradictions**
Four separation principles:
- **In space:** Hard in one location, soft in another
- **In time:** Hard during use, soft during installation
- **Upon condition:** Hard under load, soft when relaxed
- **Between system levels:** Hard at macro level, soft at micro level
**Step 5: Application of Resources**
- What substances are available? (in system, nearby, environment, products/derivatives)
- What fields are available? (waste heat, vibration, gravity, pressure)
- How can cheap/free resources substitute for expensive ones?
**Step 6: Apply Substance-Field Model**
- Model current state
- Identify incomplete or harmful models
- Apply standard solutions
**Step 7: Apply TRIZ Principles**
- If not solved yet, use contradiction matrix
- Try 2-3 most relevant principles
**Step 8: Analyze Solution**
- Does it achieve IFR?
- What new problems arise?
- Can solution be generalized to other domains?
### ARIZ Example (Abbreviated)
**Problem:** Bike lock must be strong (resist cutting) but lightweight (portable)
**Step 1:** Goal = secure bike, Resources = lock material, bike frame, environment
**Step 2:** IFR = Lock secures bike without added weight. Mini-problem: Lock, using available resources, must resist cutting without being heavy.
**Step 3:** Physical contradiction - Lock material must be thick/strong (resist cutting) AND thin/light (reduce weight)
**Step 4:** Separation - In space (strong in critical area only), Upon condition (hard when attacked, normal otherwise)
**Step 5:** Resources - Can we use bike frame itself? Environment (anchor to heavy object)?
**Step 6:** Substance-field - Add alarm field (makes cutting detectable even if lock is light)
**Step 7:** TRIZ - Principle #40 (composite materials): Use hardened steel inserts in lightweight frame. Principle #2 (taking out): Secure bike to immovable object, lock just prevents separation.
**Step 8:** Solution - Lightweight cable with selective hardening + alarm. Achieves security without excessive weight.

## 4. Combining Morphological Analysis + TRIZ
### When to Combine
**Use case:** Complex system with multiple parameters (morphological) AND contradictions within configurations (TRIZ)
### Process
**Step 1:** Build morphological box for overall system architecture
**Step 2:** Identify promising parameter combinations (3-5 configurations)
**Step 3:** For each configuration, identify embedded contradictions
- Does this configuration create any trade-offs?
- Which parameters conflict within this configuration?
**Step 4:** Apply TRIZ to resolve contradictions within each configuration
- Use TRIZ principles to eliminate trade-offs
- Improve configurations to be non-compromise solutions
**Step 5:** Re-evaluate configurations now that contradictions are resolved
- Configurations that were inferior due to contradictions may now be viable
### Example: Designing Portable Speaker
**Morphological Parameters:**
- Power: Battery | Solar | Wall plug | Hybrid
- Size: Pocket | Handheld | Tabletop | Floor
- Audio tech: Mono | Stereo | Surround | Spatial
- Material: Plastic | Metal | Wood | Fabric
- Price tier: Budget | Mid | Premium | Luxury
**Configuration 1: Pocket + Battery + Stereo + Plastic + Mid**
- Contradiction: Pocket size (small) vs Stereo (needs speaker separation for stereo imaging)
- TRIZ Solution: Principle #17 (another dimension) - Use beamforming or psychoacoustic processing to create virtual stereo from single driver
**Configuration 2: Tabletop + Solar + Surround + Wood + Premium**
- Contradiction: Solar (needs light, outdoor) vs Wood (damages in weather)
- TRIZ Solution: Principle #30 (flexible shell) - Protective cover deploys when outdoors, retracts indoors
**Outcome:** Both configurations now viable without compromises

## 5. Multi-Contradiction Problems
### Challenge
Real systems often have multiple contradictions that interact.
### Approach
**Step 1: Map all contradictions**
```
Contradiction 1: Improve A → worsens B
Contradiction 2: Improve C → worsens D
Contradiction 3: Improve A → worsens D
...
```
**Step 2: Identify primary contradiction**
- Which contradiction, if resolved, eliminates or eases others?
- Which contradiction is most critical to success?
**Step 3: Resolve primary contradiction first**
- Apply TRIZ principles
- Generate solution concepts
**Step 4: Check if resolving primary affects secondary contradictions**
- Did solution eliminate secondary contradictions?
- Did solution worsen secondary contradictions?
**Step 5: Resolve remaining contradictions**
- Apply TRIZ to each remaining contradiction
- Check for conflicts between solutions
**Step 6: Integrate solutions**
- Can multiple TRIZ principles be combined?
- Are there synergies between solutions?
### Example: Electric Vehicle Design
**Contradictions:**
1. Improve range → worsens cost (large battery expensive)
2. Improve acceleration → worsens range (high power drains battery)
3. Improve safety → worsens weight (reinforcement adds mass)
4. Reduce weight → worsens safety (less structure)
**Primary:** Range vs Cost (most critical for market adoption)
**TRIZ Solutions:**
- Principle #6 (universality): Battery also serves as structural element (improves range without added weight/cost)
- Principle #35 (parameter change): Use different battery chemistry (higher energy density)
**Secondary contradictions affected:**
- Weight reduced (battery is structure) → helps safety-weight contradiction
- Can now afford stronger materials with weight/cost savings
**Integrated solution:** Structural battery pack with high energy density cells

## Quick Decision Trees
### "Should I use morphological analysis or TRIZ?"
```
Do I have clearly defined parameters with discrete options?
├─ YES → Is there a performance trade-off/contradiction?

│ └─ NO → Use morphological analysis only
└─ NO → Do I have "improve A worsens B" situation?
├─ YES → Use TRIZ only
└─ NO → Neither applies; use other innovation methods
```
### "Which TRIZ technique should I use?"
```
Is problem well-defined with clear contradiction?
├─ YES → Use contradiction matrix + principles (template.md)
└─ NO → Is problem complex/ambiguous?
├─ YES → Use ARIZ algorithm (Section 3)
└─ NO → Model as substance-field (Section 2)
```
### "How many TRIZ principles should I try?"
```
Did first principle fully solve contradiction?
├─ YES → Done, move to evaluation
└─ NO → Try 2-3 principles recommended by matrix
Partial solution?
├─ YES → Combine principles (Section 5)
└─ NO → Re-examine contradiction (may be mis-stated)
```
