Fiber Distribution Tray With S-Shaped Cable Routing Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical fiber distribution systems face challenges in density, ease of use, and cable management, necessitating improvements in rack-mounted fiber terminations, patching, and splicing.
Innovation Solution
A building block element with a movable tray and synchronized movement features, such as gears or wheels, allows for reduced cable pull and improved cable management through S-shaped pathways and flanges, enabling secure cable mounting and easy access to connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a movable tray is used to access connectors, then ease of operation is improved, but cable management becomes more difficult due to cable pull
Solution Approach 1:
The tray is designed to be movable relative to the chassis, allowing dynamic repositioning for easier access to connectors. The slide mechanism enables the tray to move in and out while maintaining cable management through synchronized movement features that prevent cable pull.
Solution Approach 2:
A synchronized movement feature acts as an intermediary between the tray movement and cable positioning. This mechanism coordinates the tray's movement with the cable routing, ensuring cables are not pulled or damaged while still allowing easy tray repositioning for connector access.
2Reliability
If cable slack is minimized for secure mounting, then reliability is improved, but ease of operation deteriorates due to restricted access
Solution Approach 1:
The system uses dynamic tray movement to resolve the contradiction between cable security and access ease. The tray can be securely mounted with minimal cable slack when stationary, then moved dynamically for easy connector access without compromising cable integrity due to the synchronized movement features.
Solution Approach 2:
The element is divided into a stationary chassis and a movable tray, separating the cable mounting function (on the chassis) from the connector access function (on the tray). This segmentation allows cables to be securely mounted on the chassis while the tray moves independently for access purposes.
3Stability of the object's composition
If frame members are fixed for stable mounting, then stability is improved, but ease of operation worsens due to limited access flexibility
Solution Approach 1:
The frame members are designed to be hingedly mounted rather than fixed, allowing them to pivot dynamically for improved access while maintaining stability during operation. This dynamic mounting enables the frame members to adapt between stable and accessible positions as needed.
Solution Approach 2:
The frame members are separated from the tray through hinged mounting, creating an independent degree of freedom. This segmentation allows the frame members to maintain stable mounting when closed while enabling easy access when pivoted, resolving the contradiction between stability and operational flexibility.

AI summary
An optical fiber distribution system including a rack and elements which populate the rack including fiber terminations. Each element includes a chassis and a movable tray. The movable tray includes a synchronized movement device for moving a cable radius limiter. The tray includes cable terminations which extend in a line generally parallel to a direction of movement of the movable tray. Each of the cable terminations are mounted on hinged frame members positioned on each tray. The cables entering and exiting the movable tray follow a generally S-shaped pathway.
