Cable Routing Shuttle for High-Density Fiber Termination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data communication equipment in fiber optic splice enclosures faces challenges in achieving high circuit density due to limited space, requiring innovative solutions to maximize the number of optical fiber terminations while maintaining accessibility and protecting optical fiber lines.
Innovation Solution
The implementation of a cable routing storage assembly that includes a shuttle cantilevered to one or more cassettes, allowing for horizontal disposition in a chassis. This configuration enables slideable reception with a mounting structure, supporting the shuttle and cassettes coplanarly, thereby maximizing circuit density and allowing for total front access without requiring access to the rear of the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional vertical stacking configuration is used, then structural simplicity is maintained, but circuit density and space utilization are limited
Solution Approach 1:
The patent transitions from traditional vertical stacking to a horizontal configuration where circuit boards are arranged side-by-side in a planar layout. This dimensional change allows multiple boards to be accessed from the front without requiring vertical space, thereby increasing circuit density while maintaining structural manageability through standardized mounting positions.
Solution Approach 2:
The patent implements a nested arrangement where circuit boards are positioned within a chassis structure that provides standardized mounting positions. The boards are nested in a systematic pattern that optimizes space utilization, allowing maximum number of boards to be accommodated in the available horizontal space while maintaining accessibility.
2Quantity of substance
If high density configuration is implemented, then space utilization is improved, but accessibility for maintenance deteriorates
Solution Approach 1:
By arranging circuit boards horizontally in a planar configuration rather than vertically, the patent enables front-side accessibility to all boards. This dimensional reorganization allows maintenance personnel to reach all circuit boards from the front of the equipment, eliminating the need to access the rear or work in cramped vertical spaces, thus maintaining ease of operation while increasing density.
3Ease of operation
If circuit boards are arranged horizontally, then accessibility is improved, but space utilization may be reduced
Solution Approach 1:
The patent optimizes the horizontal arrangement by adjusting parameters such as board spacing, mounting position dimensions, and chassis configuration. These parameter changes allow the horizontal layout to achieve maximum space utilization while preserving front accessibility, demonstrating that proper parameter optimization can resolve the apparent trade-off between accessibility and space efficiency.

AI summary
A cable routing storage assembly for a data communication system chassis. The assembly including a shuttle including a base portion spanning between a first side of the shuttle and a second side of the shuttle. A slot is defined within the base portion and arranged between the first side and the second side. The slot extending from the back end of the shuttle along a portion of a length of the shuttle to a point proximate to a front end of the shuttle such that the base portion at the back end of the shuttle is separated between the first side and the second side. The slot being sized to slideably receive a mounting structure disposed in the chassis. A handle extends from a front end of the shuttle in front of the slot. The handle being configured to displace the shuttle relative to the chassis.
