Physical desktop wellness tracking device
Goal
Conceptualize, budget, design, prototype and ultimately produce a desktop physical wellness tracking device serving as a hub for the user's health and wellness data. Many users who are interested in tracking their health and wellness data are unsatisfied with inputting all this data into a smartphone across multiple apps. This device will serve as one centralized product that links with other health apps, and asks for a user to input data each day through a couple simple and quick gestures.
Role & contribution
-
Concept and design development
-
Mechanical design (CAD modeling, electronics integration, system dimensioning and fabrication)
-
Electrical design (Circuitry, multiple electronic components integration, custom PCB design and fabrication)
-
Product pitching and marketing plan
Outcome
Successfully built a polished-looking functional product over a course of two months. The device works independently, simply powered by a wall outlet.
Learnings
Technical:
-
Complex product design: design under cosmetic constraints of a swinging device, complex enclosure for substantial electronics integration in a constrained volume, functional features added to the enclosure.
-
System dimensioning: dimensioning of the torsion springs of the rocking mechanism.
-
Electronics integration: LCD display, multiple sensors and controllers, cosmetic LED strip.
-
Sensor design: custom optical wheel encoder and scroll wheel design.
-
Custom PCB design (with Eagle) and milling.
-
Sensor reading and analysis.
-
High fidelity prototyping (3D printing, laser-cutting, CNC-milling)
Project management and design methodologies:
-
Timeline and budget management
-
Human centered design methods
-
User interviewing and analysis
