Shape-Morphing Space Frame (SMSF) Using Unit-Cell Bistable Elements

USF inventors have created a novel space frame device and method of construction with shape-morphing, bistable capability. The apparatus includes a first structural framework formed of nodes and links, with at least one bistable link, allowing the structure to change shape while still maintaining rigidity. The space frame design may be customized to a high degree, and it could be implemented as a structural component for a wide range of uses, such as a low-cost modular building system, toys, or storage units. One valuable application of size changing surfaces may be rigid containers, such as milk crates, that are designed for large volumes. When not in use, they become cumbersome, thus it would be beneficial if the crate could easily morph into a more easily stored geometry.  

Competitive Advantages:

  •     High stability in multiple configurations
  •     Predictable and controllable bistability
  •     May be modified without damaging or rebuilding
