Passive conduit or cable modification device
| DWPI Title: Passive modification device for crimping conduit line for use in e.g. aerospace, has first modifying structure connected to first end of elongated body, and second modifying structure connected to second end of elongated body |
| Abstract: A passive modification device comprising an elongated body extending along a first axis made of a shape memory alloy with a threshold contraction along the first axis at a threshold temperature. The modification device further comprises a passageway extending along a second axis shaped to surround a conduit line extending along the second axis. The modification device further includes a first modifying structure on a first portion of the passageway and a second modifying structure on a second portion of the passageway opposite the first modifying structure. Contraction of the elongated body can cause the first modifying structure and the second modifying structure to move towards each other; where movement of at least one of the first modifying structure or the second modifying structures can be configured to modify the conduit line. The conduit line may comprise mechanical cables, electrical conductors, optical fibers, or brittle portions that readily shatter. |
| Use: Passive modification device for crimping a conduit line for use in aerospace i.e. mechanical wire operated controls, automotive i.e. throttle cables and nuclear i.e. mechanically operated damper gates. |
| Advantage: The device maximizes amount of force used to modify the conduit line, pre-loads pole to cause the means to abut against the conduit line, prevents the first modifying structure from moving, realizes movement of the first modifying structure or the second modifying structures to modify the conduit line, prevents and/or stops fluid flow through a section of the conduit line can be an arduous and complicated process. The device prevents and/or stops fluid flow through section of conduit line such as closing flow path. |
| Novelty: The device has an elongated body (102) extending along a first axis. The elongated body comprises a shape memory alloy with a threshold contraction along the first axis at a threshold temperature. A passageway (104) extends along a second axis different from the first axis. The passageway is shaped to surround a cable extending along the second axis. A first modifying structure is fixed on a first section of the passageway. A second modifying structure is fixed on a second section of the passageway opposite the first modifying structure. The first modifying structure is connected to a first end of the elongated body. The second modifying structure is connected to a second end of the elongated body, where movement of the first modifying structure or the second modifying structure is configured to permanently modify a cable. |
