Cable Tray Corner Retention Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for suspending and retaining telecommunication and power cables within buildings often result in cables being pulled over the corners of trays during installation, leading to increased labor and risk of damage, as they lack effective retention mechanisms.
Innovation Solution
The use of a support tray with retention devices, including protrusions extending from the corner areas, to prevent cables from being pulled over during installation, ensuring secure placement and easy access for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are suspended in trays without retention devices, then installation is simpler, but cables are pulled over corners causing damage and increased labor
Solution Approach 1:
The patent applies local quality by adding retention devices specifically at corner areas where cables are most likely to be pulled over, rather than making the entire tray complex. The protrusions are localized to critical retention points, providing enhanced cable security only where needed while keeping the rest of the tray structure simple and easy to install.
2Reliability
If cables are hidden in ceilings or trays, then aesthetics improve and cable protection improves, but maintenance access becomes difficult
Solution Approach 1:
The patent applies segmentation by dividing the tray into modular sections with standardized retention devices at corners. This modular design allows maintenance personnel to access specific cable sections by removing individual tray segments, making maintenance easier while keeping cables hidden and protected within the tray structure during normal operation.
3Adaptability or versatility
If trays have multiple bends and turns to outline rooms, then cable routing flexibility improves, but cable instability increases
Solution Approach 1:
The patent addresses cable instability at bends and turns by applying retention devices specifically at corner areas where cables are most susceptible to being pulled over. The protrusions at these critical locations provide localized stabilization, allowing the tray to maintain its flexible routing configuration while preventing cable displacement at the most vulnerable points.

AI summary
Devices and methods are provided for suspending and retaining telecommunication cables, power cables, and other items within or outside of a building. The devices generally include a support tray having a bottom plane and top plane, with the tray being adapted to support the article. The tray will include at least one corner area, but may include many separate corner areas. The devices will further include a retention device, which is affixed to or integrally formed with the corner area. The retention device will include at least one protrusion that extends from the corner area into an interior portion of the tray. The retention device and, more specifically, the at least one protrusion will be effective to prevent articles, such as telecommunication cables, power cables, and other items, from being pulled over the corner area of the tray during installation of the cables.
