Optical Fibre Retaining Device with Adjustable Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retaining devices for optical fibre cables in telecommunications cabinets struggle to securely align and restrain cables of varying diameters while maintaining a watertight seal, potentially damaging the cables during installation and compromising the seal.
Innovation Solution
A retaining device with a movable member and body member that adjusts channel dimensions to accommodate different fibre diameters, using a combination of projections and cam surfaces to securely hold the cables, allowing for adjustable channel widths and secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed channel dimensions are used in retaining devices, then the structure is simple and easy to manufacture, but it cannot accommodate optical fibre cables of varying diameters securely
Solution Approach 1:
The retaining device incorporates a movable member that can be adjusted relative to the body member to change the channel width. This dynamic adjustment mechanism allows the same retaining device to securely accommodate optical fibre cables of varying diameters without requiring multiple fixed configurations or complex custom designs for each cable size.
2Adaptability or versatility
If channel dimensions are made adjustable to fit different cable sizes, then adaptability improves, but the risk of damaging cables during installation increases
Solution Approach 1:
The movable member allows the channel width to be dynamically adjusted to match the specific cable diameter being installed. This ensures the channel provides the minimum necessary confinement without excessive compression, reducing the risk of cable damage while maintaining secure retention. The channel can be precisely sized to avoid over-compression of the cable.
3Reliability
If a watertight seal is maintained around cables, then protection against water ingress improves, but the ability to accommodate varying cable diameters becomes more difficult
Solution Approach 1:
The movable member can be adjusted to change the channel width while maintaining the seal integrity around the cable. The seal mechanism works in conjunction with the adjustable channel to provide a watertight barrier that adapts to different cable diameters, ensuring both seal reliability and cable size versatility simultaneously.
