HARRY: PARAMETRIC PULL TOY
Fall 2018 - 6 Weeks
Parametric Product Modeling with professor Kevin Shankwiler
Created with Michael Armstrong
CHALLENGE: Create a parametric pull toy for an adult with four distinct configurations. Manufacture one of those four using a CNC router.
MY ROLE: Concept development, CAD modeling, photography and renders.
Why a horseshoe crab?
Horseshoe crabs are really cool critters, but also make for a ridiculous seven-foot pull toy.
We were asked to make configurations for each of four moods: aggressive, cautious, chill, and oblivious. These had to affect the way a rider sat on our toy, and how the toy itself was shaped. Here's how we interpreted those moods:
One of the awesome things about parametric modeling is how you can use it for mass customization: easily and cheaply producing things at a large scale that are still customized for each individual purchaser. We incorporated this by making the size of the crab's "head" related to a person's height. The overall length stays the same for easier manufacturing & transportation.
The model we made (we call him Harry) is Cautious and fits a 5'4" person perfectly.
