Laser-cut catheter hypotube analysis
Using Finite Element Analysis to Evaluate Laser-Cut Hypo Tubes Introduction Medical device development is notoriously expensive and time-consuming. Every new design feature—whether in a catheter, stent, or surgical instrument—typically requires multiple cycles of prototyping and bench testing before it can be approved for use. Each cycle consumes materials, labor, and weeks (or […]
Custom Load Sensor Design-Proof of Concept Model
Reinventing the Load Sensor: Innovation on a Budget Foil strain gauges had their time. But development doesn’t always need high-priced lab gear. Sometimes, hardware-store parts and creativity are enough. The Problem: A Pricey Sensor Market A customer asked me to design a load sensor for a trailer hitch. Since the application could scale to […]
High-speed switch actuator analysis
High-speed switch/actuator ANSYS FEA was used to analyzed a complex switch/actuator assembly. This helped us understand the stresses during a sudden stop caused by an impact with the steel hard stop. See Figure 1. We compared this setup to one with a shock-absorbing stop, shown in Figure 6. If we can reduce the impact effects, […]
Computerized Wind Tunnel – A Successful Test
. Smarter Prototyping: How CFD and 3D Printing Are Changing Engineering From Sketch to Prototype in Days Modern engineering tools have transformed the way we develop products. What once required weeks of machining and lab testing can now be achieved in days. With hand sketches, 3D CAD, CFD simulations, and 3D printing, engineers can quickly […]
