New York City-based designer Justin Nagelberg has come up with the SA, a uniquely designed umbrella that uses the principles of origami to eliminate the metal support spines that are found in traditional umbrellas.
Like origami, The SA uses planar tension to generate its form. The inner and outer canopies expand and compress in unison to open and close the umbrella. This new design allows the umbrella to be lighter, since it does not need the added weight of an inner metal skeleton. Also, since there are no exposed, moving components, the umbrella is stronger and will last longer. Furthermore, since the material is flexible when not in tension, it can easily bounce back into shape when exposed to high winds…In addition to this, another nice feature of the umbrella is that it has more headroom underneath the canopy, since there is no metal structure taking up space.
