Industrial IoT Enclosure for Automated Vending

Designed and engineered a protective housing solution for custom PCB systems inside industrial vending machines. This enclosure enhances operational safety, protects sensitive electronics, and accelerates scalable production.

Project Objective

The objective was to eliminate exposed wiring and vulnerable PCB components inside vending machines. During maintenance and restocking, sensitive electronics were at risk of accidental damage and human contact. A durable, accessible, and cost-efficient enclosure was required to resolve these concerns while maintaining service convenience.

Engineering Solution

DFM Optimization: Designed for FDM 3D printing enabling tool-less batch production.
Integrated Access: Strategic cut-outs for switches and ports without disassembly.
Thermal Efficiency: Airflow pathways and cable routing for PCB cooling.
Wire Management: Organized internal channels preventing cable strain.

Project Impact

70% Cost Reduction: Eliminated expensive injection mold tooling investment.
Rapid Deployment: 100+ units delivered within 10 days of production.
Enhanced Safety: Full protection against dust exposure and accidental contact.

Manufacturing Highlights

Material: Industrial-grade PLA / ABS for structural durability.
Batch Production: Executed using in-house 3D printing farm.
Fitment Testing: 1:1 validation with vending backplate mounting.
