Constraints

Types of constraints that the controller would be subjected to are very few. Since a controller and console would stay in the basement, you would not ever take it outside where it would be harmed by the elements. Generally, one does not bend or take apart a controller for the fun of it (we’re an exception), so resilience and elasticity wouldn’t really be needed, nor would it be a problem.

There are really only constraints that a controller could possibly be subjected to. One of them is the constant button-mashing, which the controller is made for anyway.

The second one is the uncalled for high-velocity trip across the room when a player loses the game and enters a fit of rage. The plastic that covers a controller is hard and makes it resistant to this kind of damage. The only damage that could ever come to a controller from impact on the floor, the wall, or even the ceiling, would not be on the plastic covering, but the components inside. Another possible threat to a controller would be if food or drink was spilled on it, but even then, the damage wouldn’t be on the plastic (unless you’re drinking acid, which is unlikely).

Proposal for PS1 Controller

What product will you study?

We will study a PlayStation 1 Controller


What brand?

The brand is Sony.

What is your product designed to do?

The product is designed to control the actions of a character in a video game.

Why did you decide to choose it?

We chose it in order to see what parts allow the controller to make the characters function. Also, in order to see why Sony chose the parts they did in order for the controller to work.

What circuitry components do you think you will have to learn about to understand your product?

We will probably have to learn about transistors, diode, circuit board, controls, capacitor, conduction, protection, and insulation.

Upon doing research and finding pictured of the parts, we found a diagram of how the analog stick works. There is also both a circuit board and a printed circuit board. We also need to understand what makes the buttons pressure-sensitive, and we need to find out why the controllers are able to vibrate.

What materials is it made out of?

The controller is made out of mostly of plastic for the outside with some metals and alloys for the inner components such as the circuit board.
