Modular Cable Tie-Down Bracket for Non-Planar Fiber Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable tie-down systems in enclosures are inflexible and complex to manufacture, especially when cable entry holes are not in the same plane, leading to difficulties in routing and securing cable strength members, which can result in excessive bending and increased attenuation of fiber optic cables.
Innovation Solution
A modular cable tie-down bracket with a pipe adapter mounting portion and a cable mounting portion, allowing for flexible mounting at varying angles and easy access, featuring a screw hole and anti-rotation tabs, and the ability to be rotated and positioned differently for secure anchoring of cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cable entry holes are arranged in the same plane as the tie-down region, then manufacturing complexity is reduced, but adaptability to different cable routing configurations is limited
Solution Approach 1:
The bracket is divided into multiple segments: a mounting portion that attaches to the enclosure and a cable mounting portion that secures the cable. This segmentation allows the bracket to be positioned at different locations and orientations, accommodating various cable entry configurations while maintaining simple manufacturing of each segment
Solution Approach 2:
The bracket incorporates rotational capability through a rotation axis, allowing it to be dynamically repositioned between different orientations. This dynamic feature enables the same simple bracket design to adapt to multiple cable routing scenarios without requiring complex custom manufacturing for each configuration
2Adaptability or versatility
If cable strength members are pulled further down to reach the tie-down region, then non-planar cable entries can be accommodated, but excessive bending occurs leading to increased attenuation
Solution Approach 1:
The bracket acts as an intermediary element positioned between the cable entry hole and the tie-down region. It provides an intermediate anchoring point that allows the cable to be secured in a more direct path, reducing the need for excessive bending while still accommodating non-planar configurations
Solution Approach 2:
The bracket introduces a third-dimensional positioning solution by extending perpendicular to the enclosure face. This allows cable entry holes at different heights or positions to connect to the tie-down region through the bracket's spatial extension, reducing cable bending in the horizontal plane
3Adaptability or versatility
If the entire enclosure is replaced to accommodate different cable configurations, then adaptability is improved, but cost and complexity increase
Solution Approach 1:
The bracket design extracts the adaptability function from the enclosure itself and places it in a separate, removable bracket component. This allows the enclosure to remain simple and standardized while the bracket provides the necessary flexibility for different cable configurations
Solution Approach 2:
The bracket is designed as a universal component that can be mounted in multiple positions and orientations on standard enclosures. Its multi-functionality allows it to accommodate various cable entry configurations without requiring custom enclosure designs or replacements
