Alternative routing & termination01 · Challenge
Correct on paper can still be difficult in the real product.
During Trident and SF6 pilot builds, I identified wiring arrangements that were technically possible but created practical problems in the physical panel.

Look beyond the schematic to the real product.

My contribution
I identified the routing and serviceability issue during pilot-build work, evaluated a more practical arrangement, and proposed different routing and termination. Design Engineering reviewed and accepted the proposal.
03 · Improvement
Different routing. Different termination. Simpler implementation.
The revised approach avoided unnecessary crossing of components and better considered assembly, troubleshooting, and future field service.
Technically valid
Poor routing, crossed components, and more difficult field repair.
Practical & serviceable
Alternative routing and termination better aligned with the physical product.

Accepted, implemented, and tested
Design Engineering accepted the change. The revised products were subsequently built and passed Factory Acceptance Testing (FAT).

04 · Continuous Improvement
Not a one-time observation
Finding design, documentation, and manufacturing issues is part of my regular work. Problems discovered during builds are documented through the NSR process on a daily or weekly basis as needed for review and resolution.
Scope note
This case study intentionally omits proprietary drawings, customer information, internal specifications, and confidential technical details.
Correct on paper is not always optimal in practice.
Pilot builds reveal how a design interacts with physical space, manufacturing constraints, and service requirements.
Think about the lifecycle.
I consider not only assembly, but whether the product will be understandable and practical to troubleshoot later.
Improvement requires engineering review.
The solution came from identifying the issue, developing an alternative, and working with Design Engineering to validate it.
Project Sequoia Principle
A good engineering solution should work beyond the drawing.
Manufacturability, troubleshooting, serviceability, and validation all matter. The goal is not simply to make the design work—it is to make the system practical.
