Specialized kinematic design and mechanical engineering for companies that need motion, precision, and mechanisms that actually work.
And how kinematic synthesis solves problems that trial-and-error never will
Understanding why some mechanisms work flawlessly while others fight themselves
Every rigid body in 3D space has 6 degrees of freedom. The goal is to constrain exactly the motions you don't want—no more, no less.
When constraints equal degrees of freedom, you get deterministic positioning. Over-constrain and parts fight each other.
Instead of guessing and iterating, synthesis methods calculate the exact mechanism geometry needed to achieve specified motions.
We build working prototypes — from hand-operated models to motorized systems — to validate motion before production.
A three-legged stool never wobbles. Why? Three points define a plane—exactly constraining the seat's position. Add a fourth leg and you've over-constrained the system.
This principle scales to every mechanism. The challenge is identifying which constraints you need and placing them optimally.
Why first prototypes work — our complete pipeline from math to physical proof
We mathematically generate linkage geometry that satisfies your motion requirements. This isn't guessing — it's solving. Using Burmester theory, Freudenstein equations, and precision point methods, we start with geometry that already works.
We build a parametric CAD model and run motion analysis to verify kinematics and dynamics — positions, velocities, accelerations, forces, torques. You see it move before any metal is cut.
Most engineers stop at Layer 2. We go further — using SolidWorks Design Study to automatically iterate through variations and find optimal geometry. Because we started with synthesized geometry, we're searching a small promising region, not the entire universe.
Simulations can lie. Before you commit to production tooling, we 3D print and assemble a working model. Hold it. Move it. Feel where the forces peak. It's the best way to validate a design — and demonstrate it to stakeholders.
Mechanisms that work the first time, not the sixth time.

When your project needs a mechanism specialist, I plug in as a subcontractor
Most product development firms have great industrial designers, electrical engineers, and firmware people. But when a project needs a complex linkage, cam, or motion system, the options are limited:
You keep the client relationship. I solve the mechanism problem.
I work as a subcontractor under your project. You bill the client your rate; you pay me mine. The client sees seamless execution from your team.
What I bring:
A gap in engineering education that explains why mechanism design is so often trial-and-error
Most mechanical engineers learn to analyze mechanisms — given a linkage, calculate its motion. But they never learn to synthesize mechanisms — given a required motion, design a linkage that produces it.
That's why so much mechanism development becomes trial-and-error: sketch something, build it, see if it works, repeat. It's expensive, slow, and often fails to achieve precise motion requirements.
Kinematic synthesis uses mathematical methods developed in the 1800s — Burmester theory, precision point synthesis, the Freudenstein equation — to design mechanisms that achieve exact motion specifications. The math has existed for 150 years. It's just that engineering schools stopped teaching it.
I took graduate-level kinematic synthesis coursework at Iowa State University in 1991 — one of the handful of programs that actually taught it. Since then, I've spent three decades applying these methods at Ford, Gillette, and in my own consulting practice.
And I don't just hand you a CAD file. I build working prototypes — from manual models to motorized systems with Arduino, Raspberry Pi, or PLC controls — so you can see the mechanism run at speed, validate timing and sequences, and demonstrate it to your team.
When your team hits a wall with a mechanism that won't work no matter how many iterations they try, it's not because they're not smart. It's because they were never taught the mathematical tools to solve the problem. That's where I come in.
Whether you're stuck on a specific challenge or starting a new project, let's talk about how kinematic design can get you to a working solution faster.
