Principle 20. Continuity of Useful Action
- Make parts of a system or object work at optimal conditions continuously
- Eliminate all idle or intermittent actions or work
Principle 21. Hurrying
- Conduct a process, or certain stages (e.g. destructible, harmful or hazardous operations) at high speed
Principle 22. Turn Lemons into Lemonade
- Use harmful factors to achieve a positive effect
- Eliminate the primary harmful action by adding it to another harmful action to resolve a problem
- Amplify a harmful factor to such a degree that it is no longer harmful
Principle 23. Feedback
- Introduce feedback to improve a process or action
- If feedback is already used, change its magnitude or influence
Principle 24. Intermediary
- Use an intermediary carrier article or intermediary process
- Merge one system or object temporarily with another which can be easily removed
Principle 25. Self-service
- Make a system or object serve itself by performing auxiliary helpful functions
- Use waste or lost resources, energy, or substances
Principle 26. Copying
- Instead of an unavailable, expensive, or vulnerable object, use simpler and inexpensive copies
- Replace a system, object, or process with optical or virtual copies
- If copies are already used, move to an out of the ordinary illumination and viewing perspective
Principle 27. Cheap Disposable
- Replace an expensive system or object with a multiple of inexpensive alternatives, comprising certain less-important qualities
Principle 28. Another Sense
- Replace or supplement one sensory means with another (visible, touch, acoustic, taste or smell)
Principle 29. Fluidity
- Make solid things into fluid things
Principle 30. Thin and Flexible
- Use thin and flexible structures instead of large, three-dimensional ones
- Isolate a system or object from a potentially harmful environment using thin and flexible structures
Principle 31. Holes
- Add holes to a system or object
- If a system or object already has holes, use them to introduce a useful substance or function
Principle 32. Color Changes
- Change the colour of an object or its external environment
- Change the transparency of a system, object or an external environment
Principle 33. Homogeneity
- Make systems or object interact with others of a similar form or with similar properties
Principle 34. Discarding and Recovering
