Triz Principle 27 # Cheap short-living objects

When something is relatively expensive or causes other problems, you might be able to replace it with something cheaper that works for the moment. This is a principle than has been used many times to create a disposable society. From Gillette’s razor blades onwards, many inventors have found that a lucrative income can be created with cheap devices that people buy regularly.

Replace an inexpensive object with a multiple of inexpensive objects, comprising certain qualities (such as service life, for instance).

Use disposable paper objects to avoid the cost of cleaning and storing durable objects. Plastic cups in motels, disposable diapers, many kinds of medical supplies.
