■ Tilt or reorient the object, laying it on its side.
■ Use “another side” of a given area.
Principle 18: Mechanical vibration
■ Cause an object to oscillate or vibrate.
■ Increase the object’s frequency (even up to the ultrasonic level).
■ Use an object’s resonance frequency.
■ Use piezoelectric vibrators instead of mechanical ones.
■ Use combined ultrasonic and electromagnetic field oscillations.
Principle 19: Periodic action
■ Instead of continuous action, use periodic or pulsating actions.
■ If an action is already periodic, change the periodic magnitude or
frequency.
■ Use pauses between impulses to perform a different action.
Principle 20: Continuity of useful action
■ Carry on work continuously; make all parts of an object work at
full load, all the time.
■ Eliminate all idle or intermittent actions or work.
Principle 21: Skipping. Conduct a process, or certain stages (e.g.,
destructive, harmful, or hazardous operations), at high speed.
Principle 22: “Blessing in disguise”
■ Use harmful factors (particularly, harmful effects of the environ-
ment or surroundings) to achieve a positive effect.
■ Eliminate the primary harmful action by adding it to another
harmful action to resolve the problem.
■ Amplify a harmful factor to such a degree that it is no longer
harmful.
Principle 23: Feedback
■ Introduce feedback (referring back, cross-checking) to improve a
process or action.
■ If feedback is already used, change its magnitude or influence.
Principle 24: “Intermediary”
■ Use an intermediate carrier article or intermediary process.
■ Merge one object temporarily with another (which can be easily
removed).
Principle 25: Self-service
■ Make an object serve itself by performing auxiliary helpful functions.
■ Use waste resources, energy, or substances.
