Optical Fiber Terminal Box Volume Reduction via Segmented Fastening Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access terminal boxes have a large volume due to the wide size required for supporting a four-core SC adapter, leading to a significant space constraint and increased size, which is not efficiently utilized.
Innovation Solution
A fastening plate is introduced, allowing the adapter to be separately mounted on it, optimizing the three-dimensional space of the base and reducing the overall volume of the access terminal box by utilizing the available space more compactly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the adapter is directly mounted on the base, then the structure is simple, but the volume of the access terminal box becomes large
Solution Approach 1:
The base structure is segmented into two functional layers: the base plate provides cable leading-in and coiling functions, while the separately mounted fastening plate provides adapter mounting functions. This segmentation allows each component to be optimized independently and reduces the overall volume by eliminating the need for a large single integrated base structure.
Solution Approach 2:
The fastening plate is mounted on the upper surface of the base plate, utilizing the vertical dimension rather than expanding horizontally. This dimensional transition allows the adapter to be positioned above the base plane, effectively using three-dimensional space and reducing the horizontal footprint and overall volume of the access terminal box.
2Adaptability or versatility
If the cable leading-in area is enlarged to support four-core SC adapter, then the adapter functionality is improved, but the width size increases significantly
Solution Approach 1:
The fastening plate is positioned in the vertical dimension above the base plate, allowing four adapters to be mounted without increasing the horizontal width of the device. This vertical arrangement enables full adapter functionality while maintaining a compact horizontal footprint.
Solution Approach 2:
The fastening plate and base plate are combined into an integrated assembly where the fastening plate is mounted on the base plate. This merging allows the cable leading-in area on the base plate and the adapter mounting area on the fastening plate to work together efficiently within a compact overall structure.
