Esquisse Two - Locking System

For this week's class we are suppose to design the minimum of 3 different kinds of locking systems using a combination of balsa wood and 1mm think wire. Below shows the result of what I have designed:

Design 1

The first locking system which i designed was intended to lock 2 pieces of balsa wood together in a cross shape. The idea of this design came to me when I was thinking back on the knots that I used to do during my scouting days in high school.

Design 2

On the second design, I was thinking on how to bend the balsa wood and make it stay in a curve shape at the same time. I decided to use the wire as a frame to hold the bent balsa wood in place on the top as well as the bottom.

Design 3

The third concept that I thought of was a star and how can I hold it in place using pieces of wood stacked together. I manage to come out with a solution where I used the wire and bent it in a zig-zag position. The way to of opening this locking system is simple as I just have to turn it sideways on all 3 corners.

Design 4

Design 4 is the most simple of all because it locks 2 pieces of wood which is parallel to each other. Its design came from staples which is used to staple paper together.
