RESOLUTION OF CONTRADICTIONS
T-shooting Heuristics
Resolving Contradictions is one of the most powerful tools for solving non-standard problems. Use the following methods:
1. Resolution in Time:
- Separate contradictory requirements over time.
- Find a way to switch between states.
- Make state changes automatic.
Examples:
- Napoleon at the coronation: the pope blesses the crown first, then Napoleon places it on his own head.
- Ford only paid repairmen for the downtime of equipment.
- Sostratus carved his name into stone and wrote the ruler’s name above it, which eventually wore away over time.
2. Resolution in Space:
- Distribute contradictory properties across different parts of the system.
- Use multi-level structures.
- Apply the nesting principle.
Examples:
- Gangway steps are arranged in a staggered pattern – half the width, same functionality.
- Different tire pressures to change clearance.
- Bimetallic strip for automatic greenhouse ventilation.
3. Resolution in Relationships:
- Make the system display different properties in different interactions.
- Use various operating modes.
- Employ selective action.
Examples:
- Pills with protective coating: harmless for adults, induce vomiting in children.
- Threaded filter: permeable to water, impermeable to debris.
- Anti-reflective coating: reflects certain wavelengths, transmits others.
Key Application Rules:
1. Formulate the contradiction clearly: "It must be A to... and it must be not-A to..."
2. Consider all three methods of resolution for each contradiction.
3. Look for ways to make the state-switching automatic.
4. Use the available resources of the system.
5. Strive for an ideal solution.
Indicators of a Strong Solution:
- The contradiction is fully resolved without compromises.
- No additional costs or resources are required.
- Switching between states occurs automatically.
- The solution is universally applicable to similar problems.
