Project brief

This concept would develop a folded sheet-metal enclosure for a generic outdoor monitoring node. The work would begin with component keep-outs, connector locations, and service tasks, then turn those requirements into a small family of folded-part configurations. Design attention would center on bend access, fastener engagement, gasket compression, cable routing, and drainage paths. Flat patterns and assembly drawings would make manufacturing intent reviewable without presenting the enclosure as weather-rated. A simple thermal review would identify likely hot regions and possible ventilation tradeoffs. The proposed output is a fabrication package and prototype inspection plan, including fit checks and basic ingress observations. Formal environmental ratings would require a separately defined test program and are not claimed by this concept.

Design concept developed for this portfolio. The diagrams describe the proposed system; implementation and testing are part of the validation plan.

The engineering challenge

Reconcile manufacturable bends, component access, sealing interfaces, and heat dissipation within a compact enclosure.

Engineering approach

  1. Map component and connector keep-outs.
  2. Compare folded-part and access-panel arrangements.
  3. Detail fasteners, gasket lands, and cable entries.
  4. Prepare flat patterns and prototype inspection criteria.

Validation plan

  • Check assembly access with representative components.
  • Measure critical folded dimensions against the drawing.
  • Observe gasket seating and drainage using a controlled bench setup.

Concept scope

  • Folded sheet-metal body
  • Removable service panel
  • Gasket compression features
  • Cable entry management
  • Internal mounting rails
