Cable Hanger Structure for Variable-Diameter Fiber Cable Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable hangers are inadequate for securing fiber optic cables due to their greater variety of diameters and increased weight, which results in higher load and stress, and are not suitable for coaxial cables with different diameters.
Innovation Solution
A cable hanger design featuring a base panel with arms and locking projections that spread to accommodate cables, utilizing cantilevered or serpentine gripping members fixed at both ends to provide enhanced gripping force, and flexible configurations to accommodate various cable sizes and weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional cable hangers with rounded arms and locking projections are used, then installation is simple and stacking is easy, but they cannot provide sufficient gripping force for heavier fiber optic cables
Solution Approach 1:
The hanger is divided into distinct functional components: arms for cable engagement, locking projections for mounting, and gripping members for securing the cable. This segmentation allows each component to be optimized independently for its specific function while maintaining overall structural integrity.
Solution Approach 2:
The gripping members are designed to be flexible rather than rigid, allowing them to deflect and apply gripping force dynamically. This dynamic behavior enables the gripping members to adapt to different cable sizes and weights while providing sufficient holding force without requiring a completely rigid complex structure.
2Adaptability or versatility
If hangers are designed for multiple cable sizes, then versatility is improved, but the design becomes less optimized for specific cable types
Solution Approach 1:
Different parts of the hanger have different properties optimized for their specific functions: the arms have localized gripping surfaces with specific geometries for different cable types, the gripping members have varying flexibility and engagement depths, and the locking projections have standardized mounting interfaces. This local optimization allows the hanger to reliably accommodate multiple cable sizes while maintaining secure grip for each specific type.
3Adaptability or versatility
If gripping members are made more flexible to accommodate various cable diameters, then adaptability increases, but structural strength decreases
Solution Approach 1:
The gripping members are designed as flexible elements that can deflect and conform to different cable diameters. These flexible members are strategically positioned and dimensioned to provide adequate grip strength across a range of cable sizes while maintaining the structural integrity of the overall hanger assembly through their clever placement and connection to the rigid arms.

AI summary
A cable hanger includes: a base panel having opposed ends; a pair of arms, each of the arms attached to a respective end of the base panel and having a free end; a pair of locking projections, each of the locking projections attached to a respective free end of the arms; and a pair of gripping members, each gripping member attached to a respective arm, each gripping member having opposed ends, wherein one of the ends of each gripping member is fixed to the arms and the other of the ends of each gripping member is fixed to the arm or to the base panel. The arms and locking projections are configured to spread apart to enable insertion of a cable between the arms, wherein the gripping projections engage and grip the cable, and wherein the locking projections are configured to be inserted into the aperture of the supporting structure.
