Innovation Solution
A cable unwinding device comprising a cable clamp, a core wire clamp, a rotating device, and a translation device that works together to untwist and straighten the core wires by rotating and moving the core wire clamp around and along the cable's central axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used to untwist and straighten core wires, then operational simplicity is maintained, but productivity is very low
Solution Approach 1:
The device segments the untwisting operation into two independent coordinated movements: rotation around the cable axis (performed by the rotating device) and axial translation (performed by the translating device). This segmentation allows each device to specialize in one motion type, improving overall untwisting efficiency while keeping individual device structures relatively simple
Solution Approach 2:
The patent merges the rotating device and translating device into a single integrated system that works simultaneously on the core wire clamp. This combination enables coordinated biaxial movement (rotation + translation) to achieve efficient automated untwisting, while the modular design maintains operational simplicity
2Loss of time
If manual unwinding is used, then device complexity is low, but time consumption is high
Solution Approach 1:
The rotating device and translating device operate simultaneously and continuously during the untwisting process. The core wire clamp performs both rotational and translational movements in a continuous coordinated manner, eliminating idle time and significantly reducing total untwisting time compared to manual sequential operations
Solution Approach 2:
The device employs dynamic coordinated movement where the rotation and translation motions are coupled and occur simultaneously. This dynamic biaxial movement pattern optimizes the untwisting process by maintaining continuous engagement with the twisted core wires, reducing processing time while the modular mechanism keeps complexity manageable

AI summary
A cable unwinding device includes a cable clamp for clamping and fixing a cable, a core ware clamp for clamping two twisted core wires of the cable, a rotating device, and a translation device. The rotating device drives the core wire clamp to rotate around the central axis of the cable. The translation device drives the core wire clamp to move in a first horizontal direction parallel to the central axis of the cable. As the rotating device drives the core wire clamp to rotate around the central axis of the cable, the translation device drives the core wire clamp to move along the first horizontal direction, such that the two twisted core wires are untwisted and straightened.
