Explain the Creation Phase of radial drilling machine

Objective: 

"To generate alternative methods for providing the function, through creative thinking, brainstorming and even speculation."

Possibility for problem solving alternative methods:

 Alternative-1

Alternative-1:

  U-joint is a joint used to connect two non parallel non intersecting shafts, and it can transmit power at angle, from this we can take a reference to make a drill machine which can drill at any angle. So we have to make some modification on radial drilling machine.
