12 Equipotentiality

In a potential field, limit position changes (e.g. change operating conditions to eliminate the need to raise or lower objects in a gravity field).
  • Mechanic's pit: going under the car instead of lifting it.
  • Spring loaded parts delivery system in a factory
  • Locks in a channel between 2 bodies of water (Panama Canal)
  • Skillets in an automobile plant that bring all tools to the right position (also demonstrates Principle 10, Preliminary Action)
  • Loading dock at warehouse level, so trucks can be loaded without lifting goods.
  • Spring-loaded plate dispenser in a cafeteria: the stack always presents the top plate at counter level.
Principe 12 : Mechanic's pit: going under the car instead of lifting it.
