and my lock and key........
 

A Little History:    Locks and keys have been used since the beginning of recorded history. People have used them to protect their homes and vehicles from having things stolen from them. Some of the great inventors of these locks and keys were Robert Barron, Joseph Bramah, James Sargent, Samuel Segal, and Harry Soref. I decided to create a lock and key that would have everything that anyone wanted.

The Problem: 

The problem with locks today is that they can easily be broken. Also keys are lost and so sometimes people can't get into their own house or car.

Solutions:

    There are many solutions to this problem. First, you can have a lock indoors like a bolt lock. Next, you could have a key that never came out of the lock. Finally you could do something that no one has done before.

The Solution I chose:

    The solution I chose is the third. I came up with my own idea to solve everyone's problems. I call it the Lock 3004. The Lock 3004 looks like a simple doorknob from the inside, but from the outside all you see is a door. This way the lock works is the doorknob stops in the middle of the door and the key is always in the knob. This way the thieves can't tell that there is a doorknob on the door. This tricks them and if they try to break in, they can't. Also, the door is air tight so they can't try to stick a crowbar in it or something else.

 Model:

    Meet the Lock 3004! In the model, the farthest thing up is the door with the Lock 3004 on it. The tan is the door the white is the knob and the black chrome is the lock. Then below it is the close up of just the knob and the lock. The copper circle is the knob and the five sided polygon in black chrome is the lock.

Testing and Evaluating:

    I believe if this lock was put to the test in a real life situation, it might falter a little bit. This is because any lock can have a problem with it. With my lock it could be that because it only goes half way through the door, it might make it easier for a break in to happen. However I have no idea if this is true. It could be that my lock works perfectly. But, to really find out if it worked we would need to actually build one and put it to the test. I also think that it does meet the design brief because in the model the lock is exactly like the description in the writing. For the question if the modifications will improve the solution, I am not sure. Like I said before, there are some things that could go wrong. These are that it could make it easier for someone to break in. Also, the lock could possibly be broken and wouldn't be able to be repaired. But, I have tried my best to solve this problem and it could possibly work when put to the test.
