Bracket Securing Multiple Fiber Optic Cables to Termination Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fiber optic communication networks, securing multiple fiber optic cables to a termination box is challenging, especially under pulling forces, as existing solutions struggle to distribute forces effectively, leading to a high likelihood of failure in industry-standard pull-tests.
Innovation Solution
A bracket with planar portions and tether attachment points is designed to securely affix multiple fiber optic cables to a termination box, minimizing leverage and distributing forces directly to fasteners, thereby enhancing pull-resistance and accessibility for installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple fiber optic cables are spliced in a single termination box, then network capacity and bandwidth are increased, but the likelihood of failing a pull-test increases due to inability to secure both cables to the strongest mounting location
Solution Approach 1:
The bracket is divided into multiple planar portions (first, second, third planar portions) that can be independently secured to the termination box, with each portion providing separate tether attachment points. This segmentation allows multiple cables to be secured at different locations rather than competing for a single mounting point.
Solution Approach 2:
The bracket utilizes three-dimensional spatial arrangement with planar portions extending in different directions and tether attachment points positioned at various heights and locations. This dimensional distribution allows multiple cables to be secured at different spatial positions, effectively distributing the mechanical load across multiple mounting locations on the termination box.
2Strength
If cables are secured to the strongest mounting location, then pull-test resistance is improved, but accessibility for installation is reduced
Solution Approach 1:
The bracket provides multiple tether attachment points distributed across different planar portions, allowing installers to access and secure cables at convenient locations rather than requiring all cables to be secured at a single difficult-to-reach mounting point.
Solution Approach 2:
Different planar portions and tether attachment points are positioned to provide both strong structural support and easy installer access. The design allows certain portions to be optimized for strength while others are optimized for accessibility, with each tether attachment point providing adequate pull-resistance for its associated cable.
3Strength
If a bracket design distributes forces to multiple fasteners, then pull-test resistance is improved, but device complexity increases
Solution Approach 1:
The bracket is segmented into multiple planar portions that can be independently fastened to the termination box, with each portion distributing forces to separate fasteners. This modular segmentation achieves force distribution while maintaining a relatively simple overall structure that is easier to manufacture and install than a monolithic complex design.

AI summary
A bracket for mounting multiple fiber optic cables to a termination box includes a first substantially planar portion having one or more fastener perforations, a second substantially planar portion forming a first corner with the first substantially planar portion, and a third substantially planar portion forming a second corner with the second substantially planar portion, a protrusion of the first and second planar portions at the first corner, and a notch in the second planar portion between the first and second corners. The bracket includes a first tether attachment point having first and second recessed edges of the first and second planar portions and a second tether attachment point having a third recessed edge in the notch and a fourth recessed edge of the third planar portion. The first and second tether attachment points are configured to receive first and second tethers wrapped around the first and second corners, respectively.
