Offset L-Shaped Flanges for High Density Fiber Optic Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber optic patch panels and systems are limited by physical size, restricting the density of adapters/couplers in sub-rack enclosures and thus the channel capacity of fiber optic network cabling, which cannot accommodate increasing telecommunication needs.
Innovation Solution
The use of offset L-shaped mounting flanges on mounting plates and frames allows for interlocking or overlapping configurations, enabling a higher density of adapters/couplers without compromising performance by providing additional horizontal space within standard rack units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional mounting panels with centered flanges are used, then structural symmetry and ease of manufacture are maintained, but adapter density is limited due to wasted horizontal space
Solution Approach 1:
The mounting flanges are positioned asymmetrically relative to the panel centerline, with first flanges offset in a first direction and second flanges offset in a second direction. This asymmetric configuration eliminates wasted horizontal space and maximizes adapter density while maintaining structural integrity and ease of installation.
2Productivity
If more adapters are mounted in a sub-rack enclosure, then network capacity increases, but physical space constraints are exceeded
Solution Approach 1:
The flange offset configuration effectively utilizes horizontal space by distributing mounting points across different lateral positions. This dimensional optimization allows multiple adapters to be mounted within the same rack unit without exceeding physical space constraints, thereby increasing network capacity.
3Area of stationary object
If standard centered flange mounting is used, then manufacturing and installation simplicity are maintained, but space utilization is inefficient
Solution Approach 1:
The flanges are positioned at specific offset locations optimized for space utilization rather than uniform centering. This local quality adjustment maximizes horizontal space usage while maintaining standard manufacturing processes and installation procedures, achieving efficient space utilization without compromising ease of manufacture.
