Mechanical clarity for critical design decisions
James Wilson · Founder & Principal Engineer · Former Johnson & Johnson MedTech · 10+ years
What I specialize in:
Design-phase nonlinear finite element analysis for medical device teams facing high-consequence mechanical decisions.
When geometry, contact, and material behavior interact in ways that testing alone cannot isolate, I help teams understand what is actually driving performance before those decisions become expensive or irreversible.
Typical problem characteristics:
- Systems that undergo large deformation, where geometry and load paths change as the device operates
- Assemblies where stress fields depend on contact evolution, including frictional sliding, seating, and separation
- Nonlinear material behavior that affects device stiffness and strength (e.g. polymers, hyperelastics, shape memory alloys)
When clients bring me in:
- A critical design decision must be made, and internal assumptions need an independent technical lens
- Test results reveal behavior that is not fully explained by first-order mechanics
- Performance appears driven by internal interactions, but the dominant contributors are unclear
- Confidence is needed before committing to tooling, supplier decisions, or regulatory pathways
I focus on the problems where the next prototype must be built with intent, not hope.
Case Studies
Representative examples of the types of problems I work on:
Who I work with:
Typical collaborators:
- R&D engineers and mechanical leads at small to mid-size MedTech companies
- Design owners responsible for high-consequence decisions
- Physician-inventors validating feasibility before committing to tooling
- Early-stage teams without in-house depth in nonlinear computational mechanics
What to expect:
- Physics framing before any model gets built
- Targeted simulations focused on the high-value unknowns
- Sensitivity studies to expose what actually drives the outcome
- Clear outputs tied directly to design decisions and next steps
About James
Let’s talk about your design
A short technical call is usually all it takes to know if I can help:
James Wilson is a mechanical engineer specialized in computational mechanics applied to medical device design.
After a decade at Johnson & Johnson MedTech working on high-consequence mechanical problems across surgical instruments and robotic-assisted platforms, he founded Wilson MedTech.
James now partners with device teams to guide physics-based decisions where system behavior is sensitive, interactions dominate performance, and testing alone cannot isolate design issues.
James holds multiple patents, has presented technical work to executive-level audiences, and has contributed to the successful launch of several medical devices.
