Origami design process

In their article in the Journal of Mechanical Design, Jessica Morgan, Spencer P. Magleby and Larry L. Howell presented a design process for mechanisms that use origami (folding).

Their design process can be viewed as a separation in which there is a set of logically related decisions that must be made (subproblems that must be solved):

  1. Decide to use origami solution.
  2. Select the general material behavior options (hybrid, rigid, multiple, flexible).
  3. Select a seed origami (fold pattern).
  4. Choose modifications to the fold pattern, including the actuation method, the thickness, the hinge, and the manufacturing method.
  5. Select the precise material.

Their paper lists some aerospace applications, including bellows to protect drill shafts on interplanetary rovers, an expandable habitat for the International Space Station, and
a parabolic antenna.
