Triz Principle 20 # Continuity of useful action

Not all parts of all machines are being optimally used all of the time. We can thus improve matters by reducing this idle time or putting it to better use.

A. Carry on work continuously; make all prts of an object work at full load, all the time.

  • Flywheel (or hydraulic system) stores energy when a vehicle stops, so the motor can keep running at optimum power.
  • Run the bottleneck operations in a factory continuously, to reach the optimum pace. (From theory of constraints, or takt time operations)

B. Eliminate all idle or intermittent actions or work.

  • Print during the return of a printer carriage–dot matrix printer, daisy wheel printers, inkjet printers.
