Executive Summary

portfolio at a glance

Designing rolling stock cabins entails integrating dense, conflicting structural, mechanical, and electrical subsystems within an incredibly restrictive physical footprint. Collaborating closely with the lead contractor, Ricardo, our engineering team resolved this multi-layered spatial challenge by validating a complete 3D digital model before physical fabrication. By executing wiring routing, fluid piping models, and structural sheet metal redesigns within a unified design suite, we eliminated onsite physical interference, reduced standard production lead times, and produced an install-ready visual deployment package.

First Principle

"Validate Digitally, Assemble Seamlessly"

Physical space constraints do not bend to onsite corrections. Proactive digital validation is the singular path to zero-rework fabrication.

Model multi-system pathways simultaneously to prevent physical clashes.
Re-engineer structural enclosures using flat-pattern sheet metal to save space.
Translate complex coordinates into highly accessible 3D installation sheets.

Frequently Asked Questions

clarifications

Why choose SolidWorks Routing over standard routing?

SolidWorks Routing handles physical, parametric relationships between components in real-time, allowing layout adjustments to automatically update adjoining pipes, cables, and harnesses.

How did the sheet-metal approach improve on-site access?

Replacing thick frame members with precision-folded panels thinned structural walls. This created more interior volume and allowed for clean access panels, simplifying future appliance servicing.

What was Ricardo's role in this project?

As the main electrical contractor, Ricardo set the boundary specs and standards. We worked alongside them to integrate our subsystem seamlessly with their wider cabin layout.

How does flow simulation improve piping reliability?

By simulating water pressure throughout the modeled pipe runs, we identified and corrected high-friction bends, ensuring stable flow before manufacturing.

How did visual diagrams accelerate onsite installation?

Replacing complex, hard-to-read 2D schematics with step-by-step, exploded 3D assembly guides removed guesswork for construction crews.

What checks prevented harness wear inside the compartment?

We modeled the physical swing of harnesses and set edge guards along all sheet metal cutouts, protecting wire isolation over long-term operations.
