Exploration of Tensile Structures in Context of Ergonomics

This is a documentation my process for a final project for 24–672 Special Topics in Design, DIY, and Fabrication in Carnegie Mellon’s College of Engineering.

THE CONCEPT

Emerging from a successful cast of the “seahorse,” I knew I wanted to deeper explore artifacts at this scale; thus I began thinking about ergonomics and different types of grips.

CAD

It became clear to me that the form itself was going to take on a rather organic and complex shape — thus when it came time to CAD, I decided to try out Fusion360.

FIRST GEN OF ITERATIONS

NEXT STEPS

Upon completing the first iteration, I pulled in some of the angles on the model and tested the string on other forms. From an orthographic standpoint, the grip I had originally modeled was rather jarring and frankly, uncomfortable to look at.

FINAL FORM

After an excruciating iterative process, I landed on final form. It is printed out of tough resin on the Form2 printer and strung with waxed thread to create a tensile structure. The elastic interaction allows for a more comfortable grip that accommodates different hands.
