Universal use Electrical Socket

I’m Graduate for Mechanical Engineering, Through facing every day problem to find a right dimension socket for a plug, finding one does not guarantee tight fixture. To solve this i Came up with an idea to develop a universal socket which can attach any size electrical plug.
About Mechanism : 4*4 box consist of many small cylindrical conducting rod (Tip being Insulated) When we insert the 2 or 3 point plug , male part of plug pushes the cylindrical rod inside which completes a circuit.

Advantages over tradition Socket:

  1. Connection being rigid and easy to dislodge when powered off.
  2. Shock free, As Tip being Insulated its safe to place hand in socket.
  3. Water proof, As no holes are there in unused position.
    And most important one , its can be used for any electrical plug which makes it universally accepted .

You May Find Many flaws and incomplete explanation, Which can be discussed later if you are interested.
