Multi-Core Optical Cable Stripping Channel for Core-Safe Jacket Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical cables face challenges in accurately stripping the jacket without damaging the core, due to difficulties in identifying the position of the ripcord and requiring excessive force, which can lead to core damage and inefficiency in the process.
Innovation Solution
The optical cable features a jacket stripping channel with round corners and an identification means on the outer surface, allowing for precise location of the stripping channel, reducing the thickness variation, and incorporating a ripcord within the channel to facilitate easy separation of the jacket without core damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a ripcord is provided inside the jacket to strip the jacket, then the jacket can be removed, but the position of the ripcord is difficult to identify and the core may be damaged during cutting
Solution Approach 1:
A groove is introduced as an intermediary structure between the jacket and core. The groove serves as a guide that mediates the interaction between the cutting tool and the ripcord, ensuring the cutting depth is controlled and the ripcord position is identifiable, thus preventing core damage while enabling jacket removal
Solution Approach 2:
The groove is pre-formed in the jacket before any cutting operation. This preliminary structure prepares the path for the ripcord and defines the safe cutting depth in advance, eliminating the need for repeated cutting attempts and preventing accidental core exposure
2Ease of operation
If the jacket is cut deeply to expose the ripcord, then the ripcord can be accessed, but the core may be damaged
Solution Approach 1:
The groove acts as a physical intermediary that limits the maximum cutting depth. The cutting tool follows the groove's depth, ensuring the ripcord is exposed without penetrating into the core region, thus preventing core damage while achieving ripcord access
3Productivity
If a standard jacket stripping process is used, then the jacket can be removed, but excessive force is required and the process time is increased
Solution Approach 1:
The jacket stripping process is segmented into two distinct phases: first, cutting along the groove to create an initial opening (requiring minimal force), and second, pulling the ripcord to tear the jacket (requiring moderate force). This segmentation reduces the peak force required compared to tearing the intact jacket directly and accelerates the overall process
