Fever Thermometer
In this project, I had to design an electronic fever thermometer tailored for user-friendliness and efficiency. The device prominently displays the measured temperature and includes a memory function that stores previous readings. I focused on making the retrieval of these past temperatures as intuitive as possible for the user.
Internal components
The focus of this project were the internal electronic components, cost and assembly. The external case of the thermometer would be injection moulded using raw polypropylene. Some internal components would be components like: a lithium battery, sensor cap, PCB, LCD display, micro-usb port, and (pcb) screws.
The average manufacturing cost per product was calculated to be $5.72 per product excluding assembly.
Sustainability
Key design features include a rechargeable battery to reduce environmental waste and enhance sustainability. The thermometer is built for longevity with high-quality components and memory storage for past measurements, encouraging prolonged use. The casing is made from durable, recyclable polypropylene (PP), ensuring the product withstands daily use while being environmentally friendly. Additionally, the thermometer is designed to be repairable, with screw-fixed housing parts that facilitate easy disassembly and repair, contrasting with many non-repairable models in the market.
