Problem
The manual separation of drain wires and core wires from multi-core cables is inefficient and lacks automation, necessitating a more effective method for processing these cables.
Innovation Solution
A core wire separation apparatus that includes a holding device, a separation member with hooking portions specifically designed to hook and bend core wires while avoiding the drain wire, and a moving device to facilitate the separation process, ensuring the drain wire and core wires are separated efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual separation of drain wire and core wires is performed, then the separation can be done with simple equipment, but the processing efficiency is low
Solution Approach 1:
The separation member is divided into multiple hooking portions, each with specific geometric features designed to selectively engage core wires while avoiding the drain wire. This segmentation allows the single separation member to perform multiple functions: hooking core wires, bending them, and separating them from the drain wire, thereby improving productivity without requiring multiple separate devices
Solution Approach 2:
The hooking portions are designed with specific geometric features that enable automatic recognition and engagement of core wires based on their structural differences from the drain wire. The separation member self-adjusts to hook only the core wires through its geometric design, eliminating the need for complex sensing or control systems while maintaining high processing efficiency
2Reliability
If the separation member hooks all wires including drain wire, then the separation is more complete, but the drain wire may be damaged or bent
Solution Approach 1:
Different portions of the separation member have different geometric features tailored to the specific characteristics of core wires versus the drain wire. The hooking portions are designed with curvature and size parameters that match core wire dimensions, creating selective engagement zones that naturally exclude the drain wire while ensuring reliable hooking of core wires
Solution Approach 2:
The geometric design of the hooking portions exploits the structural difference between core wires and drain wire as a beneficial feature. The specific curvature and dimensions of the hooking portions cause them to naturally engage only with core wires, converting the structural variation from a potential problem into a selective engagement mechanism that prevents drain wire damage
3Manufacturing precision
If the hooking portion is positioned to hook core wires, then core wires are separated effectively, but the positioning must be precise to avoid drain wire
Solution Approach 1:
The separation member is designed with hooking portions that are pre-positioned beyond the core wires in the moving direction before the separation process begins. This preliminary positioning ensures that when the separation member moves, the hooking portions automatically engage the core wires at the correct location without requiring complex real-time positioning control, achieving precise separation with simple mechanics
