Key Engineering Concepts

Workflow Simplification

Reduced operator decision making through guided workflows, image-based instructions, and automated sequencing.

AI-Assisted Vision Validation

Vision-based verification was used to validate fan rotation and direction without requiring dedicated physical sensors. The system automatically adapts to varying unit layouts and component positioning.

Parallelization

Executed 14 validation processes simultaneously to improve production throughput.

Data Infrastructure

Captured raw manufacturing data in Azure for traceability, visualization, analytics, and customer reports.

Automated Validation

Automated validation of compressors, valves, sensors, electrical systems, communications, and runtime behavior.
