Plastic Optical Cable Installation for Narrow-Space Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical cables for video transmission face difficulties in passing through narrow spaces due to the size of their end plugs, and often result in excess cable length after installation, which can be an obstacle.
Innovation Solution
An optical cable laying method and set that includes a refractive index distribution-type plastic optical fiber with a cable jacket, where the jacket is removed to expose the fiber for connection to plugs, allowing the cable to be laid without plugs and adjusted in length post-laying, facilitating passage through narrow spaces and minimizing surplus cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the optical cable is laid with plugs attached at both ends, then the connection between devices is established, but the cable cannot easily pass through narrow spaces and excess cable length occurs
Solution Approach 1:
The cable is laid through narrow spaces before the plugs are attached to the ends. By performing the laying action first and the plug attachment later, the cable can easily pass through confined areas without the obstruction of plugs, and then the connection reliability is established in a subsequent step.
Solution Approach 2:
The cable installation process is divided into separate steps: first laying the cable without plugs, then separately attaching the plugs at both ends. This segmentation allows the cable to be installed through narrow spaces easily, and the connection reliability to be established in a separate subsequent step.
2Ease of operation
If the optical cable is laid with plugs attached, then the connection is established, but the cable length cannot be adjusted and surplus cable becomes an obstacle
Solution Approach 1:
The cable length is adjusted and trimmed before the plugs are attached to the ends. This preliminary action allows the cable to be cut to the exact required length, eliminating surplus cable that would otherwise be an obstacle, while the plug attachment follows as a subsequent step.
Solution Approach 2:
The installation process is segmented into distinct steps: cable laying, length adjustment/trimming, and plug attachment. This segmentation enables precise cable length control before final connection, eliminating the problem of excess cable while maintaining a systematic installation process.
