Ladder Rung Bracket Assembly for Hands-Free Cable Bundle Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing cable bundles to ladder rungs are inefficient due to variations in rung design and require additional hardware, making installation difficult and costly, especially with cable cleats.
Innovation Solution
A bracket assembly comprising a metal bracket and protective grommets with interlocking features that secure cable bundles to ladder rungs, allowing for hands-free installation and providing protection against lateral and axial movement, abrasion, and flexibility in cable diameter and rung type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cable ties or straps with cushion sleeves are used to secure cable bundles to ladder rungs, then cable protection is improved, but installation difficulty increases due to variations in rung design and proximity of obstructions
Solution Approach 1:
The bracket assembly is divided into distinct functional components: a mounting bracket portion that interfaces with the ladder rung, and a cable support portion that secures the cable bundle. This segmentation allows each portion to be optimized independently - the bracket for mounting versatility and the support for cable protection - resolving the contradiction between protection and installation ease.
Solution Approach 2:
The bracket assembly is designed with universal mounting features that accommodate various rung designs and configurations. The bracket portion can be mounted in multiple positions and orientations, making it adaptable to different obstruction scenarios and rung types, thereby improving ease of operation while maintaining cable protection capabilities.
2Adaptability or versatility
If cable cleats are used to install cable bundles to cable ladder racks, then installation alternative is provided, but device complexity and cost increase due to additional mounting hardware requirements
Solution Approach 1:
The bracket assembly merges the mounting function and cable support function into a single integrated component. The bracket portion serves as the mounting hardware while the support portion secures the cable, eliminating the need for separate mounting brackets, straps, and cushion sleeves that would otherwise be required with traditional cable cleats.
Solution Approach 2:
The bracket assembly provides a universal mounting solution that works with various cable ladder rack and rung configurations without requiring cable-specific or system-specific hardware adaptations. The design accommodates different cable types, sizes, and routing requirements through its flexible bracket mounting options.
3Object-affected harmful factors
If traditional cable securing methods are used, then cable protection is achieved, but installation time and cost increase due to difficulty of installation
Solution Approach 1:
The bracket assembly is pre-assembled with the bracket portion and support portion connected before installation. The cable support portion is pre-positioned to receive the cable bundle, and the bracket is pre-configured for mounting. This preliminary assembly eliminates time-consuming on-site adjustments and simplifies the installation process while maintaining cable protection.
Solution Approach 2:
The bracket assembly is designed to be self-installing without requiring specialized tools or additional hardware components. The integrated design allows a single component to perform both mounting and cable securing functions, enabling installers to complete the task quickly without coordinating multiple separate installation steps.

AI summary
A bracket assembly is disclosed to secure a cable bundle to a ladder rung. The bracket assembly includes a metal bracket and protective grommets. The metal bracket has a first member, side walls and second members. The first member of the metal bracket is parallel to the second members of the metal bracket. The protective grommets are secured to the metal bracket. The protective grommets have a base member, sleeves extending from the base member, a side member and a bottom member. The assembled metal bracket and protective grommets receive the ladder rung and the sleeves of the protective grommets wrap around the cable bundle positioned on the ladder rung to secure the cable bundle.
