Twisted Pair Cable Rotation for Precise Core Wire Posture Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the posture of twisted pair cables are inaccurate and inefficient due to the inability to determine the required adjustment angle before peeling off the outer layer and straightening the core wires, leading to reduced processing efficiency and accuracy.
Innovation Solution
A method involving image capture and calculation of the cable's end face to determine the initial and adjustment angles, followed by rotating the cable to achieve the desired posture, allowing precise alignment before outer layer removal and straightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection is used to adjust twisted pair core wires to predetermined posture after peeling outer layer and straightening, then the process can be completed, but the adjustment accuracy is low and processing efficiency is reduced
Solution Approach 1:
The patent applies preliminary action by capturing an image of the twisted pair cable end face and calculating the initial posture and required adjustment angle **before** peeling off the outer layer and straightening the core wires. This allows the adjustment angle to be determined in advance, eliminating the need for time-consuming visual inspection after processing and enabling more accurate and efficient posture adjustment.
2Manufacturing precision
If adjustment is performed after peeling outer layer and straightening core wires, then the posture can be adjusted, but the adjustment angle cannot be accurately determined beforehand
Solution Approach 1:
The patent calculates the initial posture of twisted pair core wires at the cutting position and determines the required adjustment angle **before** peeling the outer layer and straightening the wires. This preliminary calculation preserves the adjustment angle information that would otherwise be lost, enabling precise posture adjustment after processing without requiring time-consuming visual inspection.
Solution Approach 2:
The patent replaces the manual visual inspection method with an automated image processing and calculation system. By capturing an image of the cable end face and using computational methods to determine the adjustment angle, the system eliminates human subjective judgment and achieves more precise and consistent measurement of the required adjustment angle.

AI summary
A method for adjusting a posture of a twisted pair cable includes capturing an image of an end face of the cable and calculating the posture of twisted pair core wires of the cable at the end face based on the captured image. The method further includes calculating an initial posture of the core wires at a cutting position of a section of an outer layer of the cable to be peeled off based on the posture, a length of the section, and a twisting pitch of the cable. The method also includes calculating an adjustment angle that the cable needs to be rotated based on the initial posture and a predetermined posture of the core wires at the cutting position and rotating the cable around its central axis by the adjustment angle to adjust the posture of the core wires at the cutting position to the predetermined posture.
