A Lamina-Emergent Frustum Using Bistable Collapsible Compliant Mechanism

Competitive Advantages

  •     Exhibits perfect bistable behavior
  •     Provides a shape-changing structure that morphs from a planar lamina to a cone
  •     Can be manufactured on microscale

Summary

Our inventors have designed a cone structure using bistable col-lapsible compliant mechanism technology. The transformation from a planar lamina shape to a cone shape requires only small pulling or compressing force to switch between the two states. This new mechanism is utilized in a lamina-emergent cone, and is based on transforming a polygon spiral into spatial cone shape us-ing a mechanism composed of compliant links and joints that exhibit bistable behavior. It will provide useful functions such as switches and relays, and can be manufactured on a microscale.
