Multifilament Cable Alignment With Variable Loop Radius
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to align multi-core cables effectively, particularly in situations where the orientation of conductors after insertion into assembly machines does not correspond to the desired alignment, often requiring complex rotations that can damage the cable due to high torque and bending stresses.
Innovation Solution
A method and device that involve fixing both ends of a multi-stranded cable in separate fixing devices, increasing the distance between the ends to enlarge the loop radius, and rotating the ends simultaneously to achieve a specified orientation, reducing torsional stress and enabling easier alignment without damaging the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cable ends are clamped close together for machining, then the system length is reduced and cycle time is saved, but the cable forms a tight loop with small bend radius requiring high torque for rotation which may cause mechanical damage
Solution Approach 1:
The system dynamically adjusts the distance between fixing devices based on the cable's stiffness and loop radius. For stiff cables, the devices are positioned farther apart to create a larger loop radius, reducing bending stress and torque requirements during rotation. This dynamic adaptation resolves the contradiction between maintaining short cycle times and preventing mechanical damage.
Solution Approach 2:
The system changes the geometric parameter of the loop radius by adjusting the distance between fixing devices. By increasing the loop radius for stiff cables, the required torque for rotation is reduced, preventing mechanical damage while still maintaining efficient processing through optimized positioning.
2Length of stationary object
If the cable forms a tight loop with small bend radius, then the system length is reduced, but the torque required to rotate the cable increases significantly
Solution Approach 1:
The system dynamically adjusts the loop radius by modifying the distance between fixing devices based on cable properties. This dynamic parameter adjustment allows the system to maintain short overall length while creating sufficient loop radius to reduce rotation torque when needed.
Solution Approach 2:
The system changes the loop radius parameter by adjusting fixing device positions. For cables requiring lower torque, the radius is increased by spacing devices farther apart, directly addressing the torque reduction need while managing system length through optimized positioning.
3Stability of the object's composition
If the cable has high stiffness, then the cable maintains its shape better, but the impact of bend radius on section modulus increases, requiring higher torque for rotation
Solution Approach 1:
The system compensates for high cable stiffness by changing the loop radius parameter. By increasing the radius through greater spacing between fixing devices, the section modulus impact is reduced, lowering the torque required for rotation while the cable's inherent shape stability is maintained.
