Cable Hanger Stabilizing Members for Side-Load Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable hangers struggle to securely mount multiple cables of varying diameters and withstand side loads, particularly for fiber optic and hybrid cables that are heavier and more numerous, leading to potential dislodging under wind or side loads.
Innovation Solution
A cable hanger design featuring a flat base with arms, locking members, gripping members, and stabilizing features that provide additional support and stability through a flexible tying section and stabilizing members that engage under deflection, enhancing grip and preventing relative movement of locking members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple cable hangers are stacked or a single hanger secures multiple cables, then the number of cables mountable to a single attachment point increases, but the device complexity and structural crowding increase significantly
Solution Approach 1:
The cable hanger is designed with a universal structure that can securely mount multiple cables of varying diameters using a single attachment point. The hanger incorporates adjustable gripping members and a flexible tying section that adapts to different cable sizes, eliminating the need for multiple separate hangers or complex stacked configurations.
2Strength
If traditional cable hangers are used for heavier fiber optic and hybrid cables, then the hangers must support greater weight and stress, but the hangers may dislodge under wind or side loads
Solution Approach 1:
The cable hanger incorporates a flexible tying section that is pre-configured to become taut when cables are properly installed. This tying section provides preliminary stabilization that prevents the hanger from dislodging under subsequent wind or side loads, ensuring reliable mounting before environmental forces act on the system.
Solution Approach 2:
The hanger design allows the tying section to change its mechanical state from slack during installation to taut during operation. This parameter change provides dynamic support that adapts to the loaded condition, increasing resistance to dislodging under wind or side loads while maintaining ease of installation.
3Strength
If the tying section is taut during installation, then additional support is provided, but the cable hanger becomes difficult to install and the gripping members cannot deflect properly
Solution Approach 1:
The tying section is designed with dynamic flexibility that allows it to remain slack during the installation process, enabling easy manipulation and proper deflection of gripping members. Once the cables are securely positioned, the tying section naturally becomes taut, providing the necessary support and stabilization without requiring forceful installation actions.
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 design effectively secures multiple cables of varying diameters and resists dislodging under side loads, providing enhanced support and stability, especially in windy conditions.
Implementation Method 1
a flexible tying section extending between the support member and the first gripping members. The tying section is configured such that, when the cable hanger is not grasping a cable, the tying section has slack therein, but that sufficient deflection of the first gripping while grasping a cable can cause the tying section to become taut, thereby providing additional support to the first gripping member

AI summary
A cable hanger includes: a generally flat base with at least one opening; first and second arms extending in a first direction from opposite edges of the base; first and second locking members extending in the first direction from, respectively, ends of the first and second arms, each of the locking members comprising a respective hook; first and second gripping members, each of the first and second gripping members extending from the base or one of the arms and forming a pocket configured to receive and grasp a cable; and first and second stabilizing features, each mounted to and extending from a respective one of the first and second locking members. The first and second locking members are forced toward each other to mount the cable hanger in a mounting location vis the hooks, such movement causing the first and second gripping members to grasp a cable in the pocket. The first and second stabilizing features are configured so that engagement of the first and second stabilizing members inhibits relative movement of the first and second locking members.
