Reverse Engineering

Overview: For this project we worked in groups of 4 to break apart a device and put it back together in a better way. Our group got together and brainstormed what to do. We used a video game controller. We look it apat first. We found out that the bottoms did not work well. So we desided to make them better. We came together and thought of using silicon to replace the botton.


HYPOTHESIS: But through all of these improvements over decades of optimizations, some factors of the controller have stayed problematic. One being, the durability of these controllers, buttons, joystick, and triggers become stuck or broken. This occurs when the controller falls off a surface and lands on its front side, or if it’s in a compact space, pressing it’s buttons against a luggage or bag. We plan to fix these issues by fixing it’s material and hardware. The Ps4 controller would be improved if the material used for the buttons was silicone instead of plastic.

A Ps4 controller Is not a Ps4 controller without its parts, so here they are:

  • PSB (Printed Circuit Board): Main PCB, Optical drive controller PCB, Buttons PCB, LED PCB, and Controller PCB

  • Plastic Parts: Top main enclosure, Center main enclosure, Bottom main enclosure, triggers, buttons, dual analog sticks

  • Electronic Parts: Hard disk drive, Optical drive, Heatsink (powers the fan assembly), Power supply module, and Battery

  • Metal Parts: Top mounting bracket, Bottom mounting bracket, and Fan assembly

  • Features: Vibration monitor, Touch pad, and Light bar


What function the buttons serve:

A)Directional buttons

B )SHARE button

C )Touch pad/Touch pad button

Press the touchpad to use the touchpad button.

D )Speaker

E )OPTIONS button

F) button/ button/ button/ button

G )Right stick/R3 button

Press down on the stick to use it as the R3 button.

H )PS button

I )Stereo headset jack

J )Extension port

K )Left stick/L3 button

Press down on the stick to use it as the L3 button




Form this project I learned how to replace objects by using something else to make it better. I also learned how to be creative with others. Next time to do better I will not talk to my friends as much. Next time I will be more focused.
