Triz Principle 26 # Copying

Rather than use the expensive, delicate or inaccessible original, can you use a simple copy. This may be done physically or optically, such as using an image of some sort. Once you have a copy, you can change it different ways to achieve the desired benefit.

 A. Instead of an unavailable, expensive, fragile object, use simpler and inexpensive copies.

  • Virtual reality via computer instead of an expensive vacation
  • Listen to an audio tape instead of attending a seminar.

 B. Replace an object, or process with optical copies.

  • Do surveying from space photographs instead of on the ground.
  • Measure an object by measuring the photograph.
  • Make sonograms to evaluate the health of a fetus, instead of risking damage by direct testing.

 C. If visible optical copies are already used, move to infrared or ultraviolet copies.

  • Make images in infrared to detect heat sources, such as diseases in crops, or intruders in a security system.
