Pivotable Fiber Management Trays for Optical Closures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and routing a large number of optical fibers in fiber optic closures becomes increasingly challenging due to the need for efficient tracking and configuration of both individual and ribbonized fibers, requiring advanced fiber management systems.
Innovation Solution
The optical fiber management assembly features a configurable system with pivotable trays and adapters that support various fiber routing configurations, including individual and mass splices, allowing for flexible management of both loose and ribbonized fibers within a fiber optic closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed fiber management trays are used, then fiber routing is simple and stable, but the system lacks adaptability to different fiber configurations and routing requirements
Solution Approach 1:
The fiber management trays are designed to be pivotable rather than fixed, allowing them to rotate between a stored position (flush with the outer tray) and a deployed position (angled upward). This dynamic configuration enables the same tray structure to adapt to different fiber routing needs while maintaining structural simplicity when not in use.
Solution Approach 2:
The fiber management system is divided into multiple independent trays (outer tray and multiple inner trays) that can be individually positioned and configured. Each inner tray can be independently pivoted to the required angle, allowing flexible arrangement of fibers without requiring the entire assembly to be reconfigured.
2Quantity of substance
If multiple inner fiber management trays are added to increase fiber management capacity, then more fibers can be organized, but the closure space requirements increase
Solution Approach 1:
Multiple inner fiber management trays are nested within the outer tray structure. When not in use, the inner trays pivot to lie flush with the outer tray surface, maximizing space utilization. When needed, they can be independently positioned at angles to accommodate fiber routing while still contained within the overall footprint of the outer tray, effectively increasing fiber management capacity without proportionally increasing closure volume.
3Ease of operation
If fiber management trays are made accessible for splicing operations, then ease of operation improves, but the structural stability and compactness deteriorate
Solution Approach 1:
The trays are designed with a hinge mechanism that allows them to pivot between a stable stored position (flush with the outer tray, providing structural stability) and a deployed working position (angled upward, providing accessibility). This dynamic design enables operators to access the trays easily during splicing operations while maintaining structural integrity when the trays are in their stored position.
4Adaptability or versatility
If fixed-angle trays are used, then manufacturing precision is easier to achieve, but the ability to accommodate different routing configurations is reduced
Solution Approach 1:
Rather than manufacturing trays with fixed precision angles, the invention uses pivotable trays that can be positioned and locked at various angles during operation. This approach trades manufacturing precision for operational flexibility, allowing the same tray to be configured for different routing requirements without requiring高精度 manufacturing of fixed-angle features.
