19 Periodic action
Instead of continuous action, use periodic or pulsating actions.
• Hitting something repeatedly with a hammer
• Replace a continuous siren with a pulsed sound.
If an action is already periodic, change the periodic magnitude or frequency.
• Use Frequency Modulation to convey information, instead of Morse code.
• Replace a continuous siren with sound that changes amplitude and frequency.
Use pauses between impulses to perform a different action.
• In cardio-pulmonary respiration (CPR) breathe after every 5 chest compressions.

• Replace a continuous siren with a pulsed sound.

The colour indicates the ranking of the proposed principle to solve the contradiction:
1st,
2nd,
3rd,
4th.
This ranking reflects the frequency of occurrence of the principle in the analysed patents for this type of contradiction.
When a principle appears in first position, it means that it is statistically the most used in the patents studied for this type of problem.
