Pivoting Tray Telecommunications Chassis Cable Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in telecommunications is the ease of installation and management of fiber optic devices, particularly in extending and accessing cables within fiber optic networks, which current systems do not adequately address, leading to complexities in maintenance and accessibility.
Innovation Solution
A drawer-based telecommunications system with a rack-mountable chassis and a pivotally mounted tray that houses fiber optic devices, featuring cable management structures like split-rings and spools to manage input and output cables, allowing for smooth pivoting between closed and open positions without excessive cable pull or snagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drawer-based system with pivotally mounted tray is used to house fiber optic devices, then ease of access and installation is improved, but cable management complexity increases due to potential cable pull and snagging during tray pivoting
Solution Approach 1:
Cable management components such as spools, pulleys, or guide channels act as intermediaries between the cables and the pivoting tray. These intermediaries redirect cable paths to follow the tray's movement, preventing cable pull and snagging while maintaining ease of access during tray pivoting operations
Solution Approach 2:
The cable management system is designed to be dynamic rather than static, allowing cable routing to adapt automatically as the tray pivots between positions. This dynamic adjustment prevents cable stress and maintains proper cable tension throughout the range of motion
2Ease of manufacture
If standard 19-inch rack mounting is used for fiber optic devices, then installation standardization is improved, but cable routing flexibility is reduced due to fixed mounting positions
Solution Approach 1:
The rack-mounted chassis is divided into modular sections with standardized mounting positions for fiber optic devices. Each module can be independently configured and installed, maintaining standardization while allowing flexible cable routing within and between modules through dedicated cable access points and routing channels

AI summary
A telecommunications system includes a chassis defining a first side and an opposite second side. A tray is pivotally mounted to the chassis between a closed storage position and an open access position relative to the chassis. At least one telecommunications component is removably mounted to the tray. One of an input or output cable from the telecommunications component extends out to an exterior of the chassis from the first side of the chassis, and the other of the input or output cable from the telecommunications component follows a cable path across the chassis, positioned above the pivotable tray, and extends out to the exterior of the chassis from the opposite second side of the chassis.
