Bill of Materials
The chill pad consists of five simple components: top cover, bottom cover, air intake, grill, and fan subassembly. The assembly is fairly straight forward. There are 16 parts we identified in the assembly. It consists mostly of plastic parts which were manufactured using different molding methods. Several metal screws were used to attach the components together. There are electrical components in the assembly that we did not disassemble such as the motor, switch and the USB connector. In the table below, the parts we identified are listed along with their properties and functions.
List of Components
| Part Number | Part Name | Quantity | Weight (g) | Material | Manufacturing Process | Function | Part Image |
|---|---|---|---|---|---|---|---|
| 1 | Top Cover | 1 | Plastic | Molding | Connects to the top grill and bottom cover. Protects inner workings. | ||
| 2 | Top Grill | 1 | Plastic | Molding | Connects to the top cover. Protects the fan and allows fan blown air to go through. | ||
| 3 | Small Steel Screws | 5 | Steel | Molding | Connects the top cover to the bottom cover. | ||
| 4 | Rubber Screws | 4 | Rubber | Molding | Connects the fan assembly to the top cover. | ||
| 5 | Fan Casing | 1 | Plastic | Molding | Connects to the top cover and the fan. | ||
| 6 | Fan | 1 | Plastic | Molding | Spins and blows air through the grill. | ||
| 7 | Motor | 1 | Copper, Plastic | Connects to the fan. Spins the fan. | |||
| 8 | Felt | 1 | Felt | Glued to the bottom cover. Provides soft interface between the user and product. | |||
| 9 | Bottom Cover | 1 | Plastic | Molding | Connects to the top cover and protects the inner workings. Provides a base for the product. | ||
| 10 | Air Intake | 1 | Plastic | Molding | Connects to the bottom cover. Allows air to flow into the chillpad. | ||
| 11 | Screws | 3 | Steel | Molding | Connects the air intake to the top cover. | ||
| 12 | Rubber Stoppers | 4 | Rubber | Molding | Pushes on the top and bottom cover to provide a space in between. | ||
| 13 | Removable Rubber Gripper | 2 | Rubber | Molding | Connects to the top grill. Provides increased friction between the laptop and chillpad to keep it from moving. | ||
| 14 | USB Connector | 1 | Steel | Stamped | Connects the chillpad to the computer to draw power. | ||
| 15 | Switch | 1 | Plastic, | Molding | Allows the user to control the fan speeds. | ||
| 16 | Wires | 1 | Plastic, Copper | Connects the motor to the switch and then to the USB Connector. |
