Final Project Proposal

IDEA

We are hoping to do a build/design project. Specifically, we are interested in making a shelter that is transportable and can be easily assembled. We are also interested in the idea of an umbrella that can be folded into the smallest package possible. They’re both related ideas-- we are interested in making structures that are both structurally sound and collapsable.

METHODS

Many of the structures presented above can be thought of as rigid origami - flat panels connected by hinges. For designs that can be thought of like this, Tomohiro Tachi’s “Rigid Origami Simulator” (http://www.tsg.ne.jp/TT/software/) can prove an invaluable tool for simulating designs for their feasibility. We then plan to use multiple methods of fabricating folded structures such as laser cutting and screen printing, depending on the necessary materials we will use (cloth, metal, plastic).

BACKGROUND

Steamer Basket. Axis of folding for each leaf is radially inward (note hinge along perimeter) but sliding motion and angled shape allows for compact and flat foldability.

Hwang Kim, Urban Homeless Cocoon Unfoldable, but not necessarily flat foldable (or if flat foldable not necessarily compactly so in the unfolded state)

Miura Foldings. Image: Tom Hull. Many deployable satellite space antennas and solar panel arrays are deployed using Miura folds. It is perhaps the most widely used canonical rigid origami deployable structure used in engineering. Although "banal" it shows great compacting and is easy to fold and deploys using a single linear actuator. We could look at it for inspiration for individual panels of the shelter if we can't make it out of just one flat structure.
