Cable Hanger Insert With Wrapping Grip for Multiple Fiber Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable hangers are inadequate for securing a variety of fiber optic cables due to their limited size adaptability and inability to handle the increased weight and stress of these cables, which can lead to inefficient cable management and structural stress on antenna towers and tunnel walls.
Innovation Solution
The development of a cable hanger insert with a gripping portion and a wrapping portion, formed from materials like steel or polymeric materials, which can engage and wrap around multiple cables, providing additional gripping force and adaptability to different cable sizes, allowing conventional cable hangers to securely mount multiple cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional cable hangers are used to secure multiple cables, then the number of cables mounted per attachment point increases, but the adaptability to different cable sizes and the gripping force for heavier fiber optic cables deteriorate
Solution Approach 1:
The cable hanger is divided into multiple independent cable receiving portions, each capable of securing a separate cable. This segmentation allows each portion to be optimized for different cable sizes and types, improving adaptability while maintaining the ability to mount multiple cables simultaneously at a single attachment point.
2Quantity of substance
If conventional cable hangers are used to secure multiple cables, then the number of cables mounted per attachment point increases, but the gripping force for heavier fiber optic cables deteriorates
Solution Approach 1:
Each cable receiving portion is equipped with locally-optimized gripping structures including cantilevered tabs and flex members positioned to apply targeted gripping force. This local quality enhancement ensures that each cable, particularly heavier fiber optic cables, receives adequate gripping force independent of the total number of cables mounted.
3Quantity of substance
If stackable cable hangers are used to increase cable capacity, then the number of cables mountable per attachment point increases, but the device complexity increases
Solution Approach 1:
Multiple cable receiving portions are integrated into a single hanger body that mounts as one unit to the attachment point. This merging eliminates the need for multiple separate hangers to be stacked, reducing installation complexity while maintaining the ability to secure multiple cables simultaneously through the integrated portions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cable hanger inserts enable flexible and secure mounting of multiple cables, reducing structural stress and improving cable management by providing additional gripping force and adaptability to various cable sizes, allowing conventional hangers to efficiently handle heavier fiber optic cables.
Implementation Method 1
The cantilevered tabs 12, 16 are deployed to deflect radially outwardly when the hanger 10 receives a cable for mounting; this deflection generates a radially, inward force from each tab 12, 16 that grips the jacket of the cable.
Implementation Method 2
The flex members 618 are tripartite, with two vertically offset horizontal runs 618a, 618c merging with the arcuate sections 614 of the arms 605 and a vertical run 618b extending between the horizontal rains 618a, 618e. The gripping members 612, 616 extend from opposite sides of the vertical run 618b and are vertically offset from each other.
