Self Opening Structure

FROM SPACE

Space uses many deployment systems to deploy a mast, an antenna arm or solar panels on satellites.

CNES has developed an patented innovative concept (FR2973346) of a flexible structure, deployable spontaneously, without lock actuator. An hinge enables zigzag folding. When the system is not deployed, the structure is flat, lightweight and portable.

TO THE CHALLENGE

CNES used composite materials (carbon fibers). The structure is composed of tiles connected by a hinge. The whole structure is flattened like a deck of cards to be transportable in the folded state. When the stress is released, the structure extends automatically in length.
Find the final product, knowing that its reliability and lifetime depend on the cost of the materials.

With recycled materials that you find around you (water bottles, cartons, tape ...), create a model of your product.

Beforehand, you will need to properly target markets that are willing to buy a product that may be more expensive but which will shine by its qualities (e.g.: self opening tent ...)
