Abstract

Reconfigurable bins include at least one structural component formed of shape memory materials such as a shape memory polymer, a shape memory alloy, or a combination thereof. The shape memory material is in operative communication with an activation device adapted to provide an activation signal effective to change at least one attribute of the shape memory material such that the bin can be reconfigured from a first shape to a second shape. The reconfigurable bin can include a mesh network or may be formed of panels or a combination panels and mesh.

Claims

1. A reconfigurable storage bin adapted to achieve first and second open configurations further defining first and second fixed volumes or shapes conducive for receiving and storing first and second three-dimensional objects of differing geometric shape, respectively, said bin comprising:

at least one structural component formed predominantly by a planar sheet of shape memory material configured to undergo a change in a modulus of elasticity and/or shape upon receipt of an activation signal, wherein the change in the modulus and/or shape results in a change in a shape and/or size of the structural component, such that the bin is caused to toggle between the first and second open configurations, said at least one component defines a generally non-enclosed, and non-bifurcated interior space and an open container in the first configuration, and the space and container remain generally non-enclosed and open in the second configuration,

wherein the bin presents a continuous side wall further comprising at least one panel, and the structural component defines a complete panel.

2. The reconfigurable bin of claim 1, wherein the shape memory material is a shape memory polymer.

3. The reconfigurable bin of claim 2, wherein the shape memory polymer further comprises an electrically conductive wire embedded therein and in electrical communication with a power source.

4. The reconfigurable bin of claim 2, wherein the shape memory polymer is a thermoresponsive shape memory polymer, a photoresponsive shape memory polymer, a moisture-responsive shape memory polymer, or a combination comprising at least one of the foregoing.

5. The reconfigurable bin of claim 1, wherein the shape memory material defines a fold line of the panel, and the change results in modifying the resistance to folding at the line.

6. The reconfigurable bin of claim 1, wherein the activation signal comprises a thermal activation signal, a magnetic activation signal, an electrical activation signal, chemical activation signal, or a combination comprising at least one of the foregoing signals.

7. The reconfigurable bin of claim 1, further comprising an activation device adapted to provide the activation signal to the shape memory material.

8. A reconfigurable storage bin adapted to achieve first and second open configurations further defining first and second fixed volumes or shapes conducive for receiving and storing first and second three-dimensional objects of differing geometric shape, respectively, said bin comprising:

at least one structural component formed predominantly by a planar sheet of shape memory material configured to undergo a change in a modulus of elasticity and/or shape upon receipt of an activation signal, wherein the change in the modulus and/or shape results in a change in a shape and/or size of the structural component, such that the bin is caused to toggle between the first and second open configurations, said at least one component defines a generally non-enclosed, and non-bifurcated interior space and an open container in the first configuration, and the space and container remain generally non-enclosed and open in the second configuration,

wherein the structural component defines a complete netting.
