Optical Fibre Splice Box Rear Feed-Through Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber splice boxes lack optimal design for efficient handling and storage of optical waveguides and fiber optics, with limited utilization of space and stability, and do not provide sufficient reserve for easy splicing and mobility.
Innovation Solution
A splice box design featuring a housing with a rear wall feed-through opening for optical fibers, a movable drawer for improved mobility, and adjustable fastening means for secure fixation and strain relief, along with a splice cassette and fiber optic connectors for various formats, allowing for flexible configuration and maximum utilization of space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the feed-through opening is arranged in the left side wall, then the optical fibers can be fed through, but the overall width of the splice box is not fully utilized
Solution Approach 1:
The feed-through opening is relocated from the side wall to the rear wall, changing the spatial dimension of fiber entry. This allows optical fibers to enter from the back of the splice box, maximizing the use of internal space and enabling better cable management without increasing the overall footprint of the device.
2Ease of operation
If the drawer is fixed in the housing, then the structure is stable, but the mobility and handling of optical waveguides is limited
Solution Approach 1:
The drawer is designed with movable mounting on the housing, allowing it to be pulled out or swiveled. This dynamic design enables easy access to optical waveguides and splicing components while maintaining structural stability through proper attachment mechanisms that allow controlled movement rather than rigid fixation.
3Ease of operation
If sufficient reserve of optical fibers is accommodated in the housing, then easy handling during splicing is enabled, but the space for other components is reduced
Solution Approach 1:
By arranging the feed-through opening in the rear wall, the patent creates optimal spatial conditions for routing optical fibers from the back through the housing. This dimensional change allows sufficient fiber reserve to be accommodated in the internal space while maintaining access to all components, effectively resolving the space conflict between fiber storage and component placement.
