Problem Definition & Field Context
Field Observations & User Pain Points:
Standard outdoor lighting solutions lack adaptability across shifting camping scenarios (e.g., hand-held navigation vs. multi-point tent illumination). Common mechanical connectors (USB ports, latches) fail under humidity, dust, and continuous mechanical stress.
Design Requirements:
- Connector Reliability: Sealed, wear-free magnetic power/data distribution interface.
- Lighting Versatility: Dual LED array for task lighting and controlled insect-repellent spectrum emission.
- Smart Integration: Embedded PIR sensor for automated perimeter safety lighting.
- Modular Scalability: Structural daisy-chaining capability across tent frames and support poles.
System Architecture & Technical Specification
Mechanical & Electronics Integration:
- Power & Data Interface: Custom 4-pin spring-loaded Pogo connection (+VCC, GND, IoT Data IN, IoT Data OUT) with neodymium magnet alignment for self-locating docking.
- Housing & Ergonomics: Extruded aluminum core with UV-stabilized polycarbonate diffuser housing. Form factor optimized for single-handed grip and low-profile mounting.
- Sensing & Control: Recessed PIR movement sensor preventing accidental actuation during transport; wireless IoT module for remote cluster management via mobile application.
Parametric CAD Development & DfM
Surface Engineering & Light Diffusion:
Geometry Optimization:Â Parametric Voronoi pattern generated in Grasshopper, driven by attractor points mapped around the PIR sensor aperture.
