Dual-Orientation Cable Tray Exit Adapter for Varied Wire Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exit adapters for cable trays are not adaptable to different types of trays with varying wire spacing or side heights, and are typically configured for a single orientation, leading to inventory management challenges and limited applicability.
Innovation Solution
The exit adapter features a ramp with support hooks and tabs that can be oriented in two ways to secure to the cable tray, allowing it to be installed through a side wall or over it, and includes adjustable height mechanisms to accommodate modified and unmodified trays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional exit adapters are configured for a single orientation and specific tray type, then they can be manufactured simply, but they lack adaptability to different cable tray types and orientations
Solution Approach 1:
The exit adapter is designed with dual-orientation capability, allowing it to be installed in either orientation A (engaging floor wires) or orientation B (engaging side wires). The adapter incorporates wire engagement features on both ends, enabling a single adapter design to serve multiple cable tray configurations and orientations, thereby achieving universality without requiring multiple specialized adapters
Solution Approach 2:
The adapter employs asymmetric wire engagement features positioned at different ends - one end configured for floor wire engagement and the other for side wire engagement. This asymmetric design allows the adapter to adapt to different tray types and orientations while maintaining structural integrity and proper cable routing functionality
2Adaptability or versatility
If multiple specialized adapters are manufactured for different tray types, then adaptability is improved, but inventory management complexity and costs increase
Solution Approach 1:
By designing a single exit adapter that can function in two orientations with different wire engagement modes, the invention eliminates the need to maintain separate inventory for different tray types. The universal adapter design reduces inventory variety while maintaining full compatibility with various wire configurations through its dual-orientation capability
3Ease of operation
If the adapter is designed to engage floor wires only, then installation is simplified, but it cannot accommodate trays requiring side wire engagement
Solution Approach 1:
The adapter incorporates both floor wire engagement features and side wire engagement features, allowing installers to select the appropriate engagement mode based on the specific tray configuration. This universal design maintains installation simplicity while expanding applicability to both modified trays (requiring side wire engagement) and unmodified trays (using floor wire engagement)

AI summary
Exit adapters are disclosed to provide cable exits for cable trays, including cable trays formed from lattices of wires. An exit adapter can include a ramp that defines a cable path. Some exit adapters can be selectively installed in either of a first orientation or a second orientation, to route cable out of a cable tray (e.g., for use with, respectively, a modified cable tray or an unmodified cable tray).
