Engineering
Below is a brief overview of my design and engineering process for the Mood Player, covering CAD development, PCB and electronics design, and full system integration of key components including connectors, display, actuators, and sensors
System Architecture
Seamless integration of mechanical and electronic components with a highly optimize system architecture to enable a brushless DC motor (BLDC) while keeping overall thickness at minimum with adequate battery capacity
DFM and DFA
I engineered the CAD for DFM and DFA, applying stack up tolerance analysis, FEA for structural and thermal margins, and kinematic simulations to validate moving part clearances, wear interfaces, and assembly robustness.
CNC machined unibody
The main chasis is machined from 6061 aluminum and serves as an external frame, adding structural rigidity while delivering a premium tactile experience
Injection molded core structure
The core structure is an injection molded ABS chassis that functions as the primary datum and mounting backbone for the PCB, battery, stereo speakers, and a sheet metal dial bracket
Prototype
Collaborated with external manufacturing partners to execute prototype builds, sourcing and fabricating custom parts to specification across plastics, machined metals, sheet metal, and PCB assemblies, and coordinating DFM feedback, tolerances, and build readiness through each iteration.
