Extractable Fiber Organizer Tray for Compact Terminal Enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal enclosures for optical fibers lack the capability to efficiently manage multiple fibers per subscriber, especially in high-population areas, where regulations require separate fibers for each provider, necessitating a solution that allows for easy installation, splicing, and storage of fibers with a compact design.
Innovation Solution
A terminal enclosure with an extractable fiber organizer tray that integrates splicing, storage, and connector mounting functions, featuring a two-level cable guide and fiber spools to secure and protect fibers, allowing for efficient management and minimization of the enclosure's volume, made from materials like Polycarbonate and Acrylonitrile Butadiene Styrene for ease of manufacturing and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fibers are installed per subscriber to meet regulatory requirements, then fiber capacity and adaptability are improved, but enclosure complexity and difficulty of management increase
Solution Approach 1:
The enclosure is divided into functional modules: a base unit and an extractable tray. The tray can be removed for external fiber management operations, separating the permanent enclosure structure from the temporary fiber handling components. This segmentation allows multiple fibers to be managed without permanently complicating the enclosure design.
Solution Approach 2:
The tray containing fiber management functions is extracted from the base enclosure. This allows all fiber splicing, storage, and connector mounting operations to be performed externally on the tray, while the base enclosure remains simple and compact. The extraction principle resolves the contradiction by moving complexity outside the permanent structure.
2Ease of operation
If an extractable tray with all management functions is implemented, then ease of operation and installation are improved, but device complexity increases
Solution Approach 1:
Multiple fiber management functions (splicing, storage, connector mounting) are merged into a single extractable tray. This consolidation allows all operations to be performed in one location external to the base enclosure, simplifying installation procedures despite the tray itself being a multi-functional component.
Solution Approach 2:
The extractable tray is designed as a universal platform that can accommodate multiple fibers, splices, and connectors simultaneously. Its multi-functional design allows it to handle various fiber management tasks, improving ease of operation while the modular nature keeps the overall system manageable.
3Productivity
If fiber storage and splicing areas are integrated on the tray, then fiber management efficiency is improved, but tray volume and enclosure size increase
Solution Approach 1:
The tray utilizes three-dimensional space efficiently by arranging fiber storage areas, splicing zones, and connector mounting positions in vertical and lateral dimensions rather than only horizontal space. This dimensional arrangement maximizes fiber management capacity within a compact tray volume.
Solution Approach 2:
The tray design nests fiber storage and splicing functions within a compact external structure. Smaller functional elements are arranged to fit within the overall tray footprint, maximizing space utilization and keeping the tray volume minimal while maintaining all necessary fiber management capabilities.
