Foldable tube with unitary hinge devices, systems, and methods
Methods, systems, and devices for foldable tube with unitary hinge are provided in accordance with various embodiments. Some embodiments include a device that may include one or more foldable tube sections configured to facilitate the deployment of an object with respect to an end portion of at least one of the one or more foldable tube sections; each of the one or more foldable tube sections may include one or more unitary hinge regions. The unitary hinge regions may include one or more longitudinal hinge regions configured to enable folding that is transverse to a primary axis of a respective foldable tube section. The unitary hinge regions may include a lateral hinge region configured to enable flattening that is parallel to a primary axis of a respective foldable tube section. Some embodiments may include a wire harness disposed within an interior portion of one or more foldable tube sections.
1. A device comprising:
one or more foldable tube sections configured to facilitate the deployment of an object with respect to an end portion of at least one of the one or more foldable tube sections, wherein:
each of the one or more foldable tube sections includes one or more unitary hinge regions;
the one or more foldable tube sections include a composite material with a plurality of layers, wherein the plurality of layers includes one or more carbon fiber layers;
at least one of the unitary hinge regions includes a longitudinal hinge region configured to enable folding that is transverse to a primary axis of a respective foldable tube section; and
at least one of the unitary hinge regions includes a lateral hinge region configured to enable flattening that is parallel to a primary axis of a respective foldable tube section such that the lateral hinge region includes one or more layers devoid of carbon fibers that extend along a length of the respective foldable tube segment outside of the longitudinal hinge region.
2. The device of claim 1 , wherein the longitudinal hinge region includes at least a portion of the one or more carbon fiber layers.
3. The device of claim 1 , further comprising one or more circumferential bands proximal to the longitudinal hinge region.
4. The device of claim 3 , wherein the one or more circumferential bands are formed from one or more composite material layers.
5. The device of claim 1 , wherein the longitudinal hinge region includes two or more apertures configured to allow the respective foldable tube section to fold and to flatten at least a portion of the longitudinal hinge region.
6. The device of claim 1 , wherein the longitudinal hinge region includes one or more relief slots oriented around a circumference of a respective foldable tube section.
7. The device of claim 6 , wherein the one or more relief slots allow the longitudinal hinge region to self-buckle.
8. The device of claim 1 , further comprising a wire harness disposed within an interior portion of at least one of the one or more foldable tube sections.
9. The device of claim 8 , wherein the wire harness includes one or more necked down regions configured to coincide with one or more of the respective longitudinal hinge regions.
10. The device of claim 8 , wherein the wire harness is configured to at least fold or flex laterally in a region of the one or more foldable tube sections other than the longitudinal hinge region.
11. The device of claim 8 , wherein the wire harness includes one or more relief slots.
12. The device of claim 1 , wherein a first foldable tube section from the one or more foldable tube sections is configured to stack with a second foldable tube section from the one or more foldable tube sections when at least one of the one or more unitary hinge regions is folded and the first foldable tube section and the second foldable tube section are compressed.
13. The device of claim 1 , wherein the one or more foldable tube sections are fabricated to compress to provide a kickoff spring functionality for deployment of the one or more foldable tube sections.
14. The device of claim 1 , further comprising one or more tube interfaces coupled with one or more end portions of at least one of the one or more foldable tube sections.
15. The device of claim 14 , wherein the object includes one or more solar panels coupled with at least one of the one or more foldable tube sections utilizing at least one of the one or more tube interfaces.
16. The device of claim 1 , further comprising one or more saddle components configured to constrain at least one of the one or more foldable tube sections during at least a folding or a compressing of the one or more foldable tube sections.
17. The device of claim 1 , wherein the one or more carbon fiber layers include a first carbon fiber layer that extends around a first portion of the respective foldable tube segment and a second carbon fiber layer that extends around a second portion of the respective foldable tube segment such that the one or more layers devoid of carbon fibers extend between a gap separating the first portion of the respective foldable tube segment and the second portion of the respective foldable tube segment.
18. The device of claim 17 , wherein the one or more layers devoid of carbon fibers include one or more fiberglass layers.
