Design Scenario I chose this project because I had a great interest in making a false bottom lock box. After some research I learned of a drawer whos lock mechanism was the drawers being pulled out and aligned. I was fascinated by the mechanism and wanted to design my own unique box.

I designed this project so that I can learn about simple solutions to problems and so that I could have my own unique lock box.

Design Brief

I am going to design and make a hidden drawer lock box. It will feature:

Three drawers that can be freely pulled out

If all three drawers are aligned in the correct manner, the hidden drawer will become accessible

A lever to maximize the linear movement caused by the peg key

Inspirational ItemsMy most inspirational item was the hidden drawer design as previously seen

Once I decided I liked this design idea, I did more research and discovered other designs

I quickly found that my original similar design was very unique and one-of-a-kind
