Possible Solutions for Apply Translational Energy to Nail
Hundreds or Thousands
This represents a new decomposition that assumes an electrical energy source and the accumulation of energy in the mechanical domain.
The text uses morphological analysis (but calls it systematic exploration). As many methods as possible to accomplish each function are determined. Then feasible combinations are identified.
Exhibit 6-10 In this solution concept, a solenoid compresses a spring and then releases it repeatedly in order to drive the nail with multiple impacts
Exhibit 6-11 Multiple solutions arising from the combination of a motor with transmission, a spring, and single impact. The motor winds a spinning, accumulating potential energy which is then delivered to the nail in a single blow.
