Bracelet designed to prevent drowsy driving
Group project with Michiel Sweere, Justin van der Bijl, Arend Roijakkers, Preshand Rathipal, Maelle Perrier
My main role: Designer of the exterior
Background
Drowsy driving is a major problem that influences street safety, leading to accidents, injuries, and even fatalities. Research from the National Highway Traffic Safety Administration suggests that an average of 328,000 crashes occur annually.Our goal was to use a technique that accurate and create a design that is affordable and user-friendly.
Space Estimation and First Design
For the first design, dimensions were calculated to ensure a space-efficient housing while being compact for comfort.
Initial Attachment
Mechanism
In the second iteration of the design, the opening and closing of the lid was considered. A design had to be made where we can easily access the electronics for future errors while also making sure it doesn’t open unintentionally.
Iterated Attachment Mechanism
Due to the 3D printing materials lack of elasticity, the snap fit attachment had to be reconsidered. Iterations were made, new design had 4 arms that will fit the 4 holes in the lid tightly to ensure it fits but stays close
Final Model and Physical Design
The final design is focused on achieving high accuracy. Having tried putting the sensor on the bottom of the design, the sensor failed to gain a accurate heart rate from only measuring the wrist. The end result led us to measure the heart rate on the finger instead, and by doing so, the sensor is able to get a high accuracy heart rate reading.
