Bracket Assembly with Sliding Tether for Ladder Rung Cable Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable installations in ladder racks require complex and time-consuming methods to secure small cables or bundles, often leading to cable abrasion with 45-degree cable ties and increased costs with additional coatings or sleeving, and complex figure eight configurations.
Innovation Solution
A bracket assembly that includes a tether and bracket with a rung attachment portion, ratchet passageway, and cable attachment portion, allowing for quick and secure 90-degree cable tie installation without additional fasteners or complex installations, using a tether that slides between unlatched and latched positions to engage the ladder rung.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable ties are used to secure small cables to ladder rungs, then cables can be secured to the ladder rack, but the installation process becomes complex and time-consuming requiring additional coatings or complex figure eight configurations
Solution Approach 1:
The cable tie system is segmented into a bracket assembly with a tether that has a retention pin, separating the securing function from the traditional cable tie application. This allows the cable tie to be installed in a simple 90-degree configuration rather than complex figure eight patterns, improving installation speed while maintaining securing reliability
Solution Approach 2:
The bracket assembly acts as an intermediary device between the cable tie and the ladder rung. The retention pin on the tether engages with the rung attachment portion to secure the bracket to the ladder rung, while the cable attachment portion secures the cable tie, eliminating the need for complex cable tie configurations
2Ease of manufacture
If 45-degree cable ties are used to secure cables, then cables can be attached to ladder rungs, but cable abrasion occurs requiring additional coatings or sleeving
Solution Approach 1:
Instead of angling the cable tie at 45 degrees across the cable (conventional method), the bracket assembly inverts the approach by securing the cable tie at a 90-degree angle perpendicular to the ladder rung. The retention pin engages horizontally with the rung attachment portion, directing force away from the cable and preventing abrasion while maintaining installation simplicity
Solution Approach 2:
The bracket assembly serves as an intermediary that transfers the securing force between the cable tie and ladder rung without the cable tie directly contacting the ladder rung at an abrasive angle. The tether and retention pin mechanism mediates the force transmission, protecting the cable from abrasion
3Object-affected harmful factors
If additional coatings or sleeving are applied to prevent cable abrasion, then cable protection is improved, but installation costs increase
Solution Approach 1:
The solution extracts the cable protection function from the cable tie system itself and relocates it to the bracket assembly design. By taking out the need for additional coatings or sleeving and replacing it with the 90-degree bracket mounting geometry, cable protection is achieved without adding costly components or materials
Solution Approach 2:
Instead of using expensive additional coatings or sleeving materials, the solution uses a simple, inexpensive bracket assembly with a retention pin mechanism. The bracket provides the necessary protection and force distribution using basic structural elements rather than specialized protective materials
4Reliability
If conventional cable tie methods are used, then cables can be secured to ladder rungs, but installation time increases due to complex configurations
Solution Approach 1:
The bracket assembly is pre-configured with the retention pin and rung attachment portion designed to engage in a single 90-degree motion. This preliminary design of the engagement geometry eliminates the need for complex figure eight configurations during installation, reducing installation time while maintaining securing strength
Solution Approach 2:
The invention inverts the traditional cable tie application method by using a 90-degree perpendicular mounting approach instead of angled configurations. This simple geometric change reduces installation complexity and time while maintaining or improving the reliability of cable securing through the retention pin engagement mechanism

AI summary
A bracket assembly that secures a cable to a ladder rung with first and second beam flanges extending from a beam web. The bracket assembly includes a bracket and a tether connected to the bracket. The bracket has a rung attachment portion configured to receive the second beam flange and a cable attachment portion extending from the rung attachment portion. The tether has a retention pin. The tether is slidable between an initial position and a latched position. In the latched position, the retention pin moves into engagement with the rung attachment portion to engage the second beam flange thereby latching the ladder rung to the bracket assembly.
