Objective

• To graphically represent a keyed entry locking
  deadbolt and door knob system in Pro-Engineer
  Wildfire.
• To create a deadbolt and door knob each
  incorporating a five-pin locking mechanism
  including a tumbler, cylinder, upper and lower
  pins, springs, and buffers.
• To incorporate latches and door jams to
  demonstrate the functionality of the deadbolt and
  door knob in everyday life.

Challenges

• We had to be extremely accurate in measuring the
  intricate parts that were involved in this
  project.
• The actual modeling was difficult since each
  piece is complex and has ample detail, all of
  which is essential to the workings of the system.
  
• The assembly was the most difficult of all since
  each mechanism involved several cam, slot, and
  spring connections.
