Solution Overview

Problem

Conventional splice trays and enclosures are inadequate for efficiently accommodating and splicing high fiber-count cables, leading to inefficiencies and difficulties in managing increasing numbers of optical fibers, especially in environments with varying regulatory requirements.

Innovation Solution

The design includes a splice enclosure with a pivotally coupled splice tray assembly that allows for easy access and organization, featuring pivotally coupled splice trays, a divider plate, and anti-twist clips to manage and secure optical fibers, along with a latch system for secure positioning, enabling efficient splicing and storage of high fiber-count cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional splice trays are used to accommodate optical fibers, then the basic splicing function is provided, but the capacity is insufficient to accommodate increasing numbers of optical fibers efficiently

Engineering Contradiction:
Improvenumber of optical fibersVSAvoidsplicing efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The splice tray is divided into multiple modular sections or compartments, each capable of holding a specific number of fiber splices. This segmentation allows the system to scale capacity by adding more modules while maintaining organized, efficient access to individual fiber groups, thereby accommodating increasing fiber counts without compromising splicing productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The splice tray design utilizes three-dimensional space more effectively by implementing vertical stacking capabilities, multi-level compartments, or tiered structures. This dimensional approach allows significantly more fiber splices to be accommodated within the same horizontal footprint, increasing capacity while maintaining ease of access and splicing efficiency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If more optical fibers are spliced and placed in splice trays, then the capacity requirement increases, but it becomes difficult to perform splicing and place spliced fibers into the trays in an efficient manner

Engineering Contradiction:
Improvenumber of spliced optical fibersVSAvoidsplicing operation efficiency
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The splice tray is divided into multiple modular sections or compartments, each capable of holding a specific number of fiber splices. This segmentation allows the system to scale capacity by adding more modules while maintaining organized, efficient access to individual fiber groups, thereby accommodating increasing fiber counts without compromising splicing productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design incorporates fiber management accessories such as clips, retainers, and routing guides that act as intermediaries to organize and control fiber paths. These elements facilitate the efficient placement and management of numerous spliced fibers within the tray, reducing complexity and improving ease of operation as fiber counts increase.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If the splice tray structure is made more complex to accommodate high fiber-count cables, then the capacity increases, but the device complexity increases

Engineering Contradiction:
Improvefiber count capacityVSAvoidsplice tray structure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The splice tray is divided into multiple modular sections or compartments, each capable of holding a specific number of fiber splices. This segmentation allows the system to scale capacity by adding more modules while maintaining organized, efficient access to individual fiber groups, thereby accommodating increasing fiber counts without compromising splicing productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The splice tray design incorporates universal, standardized components and configurations that can accommodate different fiber counts through modular assembly rather than requiring entirely different structural designs. This multi-functionality allows the same basic tray architecture to serve multiple capacity requirements, increasing fiber count capability while minimizing structural complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A splice tray may include a tray base including a base panel and flange associated with a perimeter of the base panel and extending outward from the base panel. The splice tray may also include a flexible latch extending from an outer surface of the flange of the tray base. The latch may selectively prevent and allow the splice tray to pivot with respect to a splice tray assembly in which the splice tray is received. The splice tray may also include a splice holder configured to hold a plurality of spliced optical fibers. The splice holder may include a holder base coupled to the tray base, and a plurality of ribs associated with the holder base and defining a plurality of recesses configured to receive at least one spliced optical fiber. The splice tray may also include a cover removably coupled to the tray base and/or splice holder.
