Pattern No. 28 Replacement of a mechanical system

Pattern No. 27 An inexpensive short-life object instead of an expen- 

Let us discuss all these inventive patterns and discover how they may be related to finding inventive design concepts in the case of our example. 

This pattern has four specialized heuristics, each of which may be potentially useful  

Replace a mechanical system with an optical, acoustical, or odor system 

Out of these three heuristics, the second one seems to be most feasible. An acoustic system is a system producing sounds or sound waves as a result of a moving membrane, which is driven by a flowing electric current. We can imagine a situation in which an object is placed on a horizontally positioned membrane and a constant current is applied the object will be raised and will be kept in this new position as long as the constant current is applied.
