Model Design History:

Before any initial prototypes to be printed, CAD models were created in order to portray the idea of the "push" and "pull" interactive configurations that the team was aiming for. These designs were created for the "Proof of Concept" presentation before entering a design review and re-design before printing:

After the design review with the sponsor, tweaks were made to the design to make it more feasible for a 3D printed prototype.

After completion of the initial rubber band testing, the team focused on producing a design that would reflect as close to a final iteration as possible. This including changing the dimensions to reflect the size and shape of a real surgical tool, as well as changing the tolerancing and material in order to provide a smoother translational movement.

Strain:

CAD File Folders:

While the CAD model of the strain device was essential to the overall design process, the team placed a higher priority on the actual development of the digital image correlation software via Matlab. This is because the team wanted the data acquisition system and procedure to be accurate before attempting to manufacture a real handheld device. Therefore these files should only be used for a visual guide of what the handheld device should look like and should not be referenced for any dimensions or tolerancing.
