One of my projects while working for LORD Corporation was to design the housing and other required components for a sensor and set of electronics for a stiffness tester that would illuminate to indicate whether or not the component passed inspection.
I selected appropriate sensor and electronics parts to accommodate the capability and geometric needs of the part. I designed an enclosure for these parts, and modify the existing tester design to include my additions using Autodesk Inventor. I then created engineering drawings such that my parts could be made in-house. My components are sold with the stiffness tester to clients for critical part maintenance.
