Mechanical R&D at the Interfaces
Mechanical R&D at the Interfaces
I work on mechanical R&D for high-reliability hardware, with experience spanning precision manufacturing, endoscopic camera systems, reusable medical handheld devices, and design transfer.
Much of my work begins where individual parts have passed inspection, but the assembled system still fails — at the interfaces between structure, optics, sealing, shielding, cables, manufacturing processes, and repeated use.
I investigate failures by defining the symptom, isolating variables, reproducing the mechanism, and verifying the change with evidence. ChrisWuTech is where I preserve the engineering reasoning behind those investigations.
Engineering Path
Engineering Path
My engineering path runs from the manufacturing floor, through die casting and CNC projects, to mechanical R&D, medical hardware, and design transfer. I started where parts are actually made and moved toward design without leaving that context behind.
That sequence is why I read a drawing and a supplier’s process as one system. When a part comes back out of tolerance, damaged at the surface, or delaminated after assembly, the useful question is rarely “who made the mistake.” It is whether the design asked for something the process could not repeat, whether the process drifted from what was qualified, or whether the inspection was never capable of catching the failure in the first place.
Most of what I contribute sits in that gap—between what a drawing specifies, what a factory can hold, and what the product has to survive in use.
