Solution Overview

Problem

Existing optical fibre tray assemblies require increased space and tray diameter to organize a larger number of optical fibre elements, leading to inefficiencies in compact storage and handling.

Innovation Solution

The optical fibre tray assembly features a lower and upper tray with cooperating hinge means, allowing for pivotable connection and guiding of optical fibre elements between the trays without the need for a bypass channel, thereby reducing the overall size and optimizing the organizing area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a plurality of trays is arranged in series with pivotable support, then optical fibre elements can be organized without interference, but the overall assembly requires increased space and tray diameter

Engineering Contradiction:
Improveoptical fibre organizationVSAvoidassembly space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent implements nesting by placing the upper tray directly on top of the lower tray, with the upper tray's organizing area positioned over the lower tray's organizing area. The upper tray is supported pivotably on the lower tray through hinge means, creating a nested configuration where one tray is contained within the spatial envelope of the other. This nesting arrangement allows both trays to be accessed independently while minimizing the overall footprint of the assembly, resolving the contradiction between operational ease and space requirements.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent transitions from a horizontal series arrangement of trays to a vertical stacked configuration. By utilizing the vertical dimension (z-axis) instead of extending horizontally, the assembly accommodates multiple organizing areas without increasing the lateral footprint. The pivotable hinge connection enables vertical stacking while maintaining accessibility, effectively solving the space constraint problem by exploiting three-dimensional space utilization.

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

2Quantity of substance

If tray diameter is increased to organize more optical fibre elements, then organizing capacity increases, but handling efficiency and compactness deteriorate

Engineering Contradiction:
Improvenumber of optical fibre elementsVSAvoidhandling efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent divides the organizing function into multiple separate trays (upper and lower), each capable of organizing optical fibre elements independently. Instead of requiring a single large-diameter tray to accommodate all fibres, the system segments the organizing capacity across multiple smaller trays stacked vertically. This segmentation maintains compact dimensions while increasing total organizing capacity, as each tray can be handled and accessed separately, preserving handling efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent increases organizing capacity by utilizing the vertical dimension rather than expanding the horizontal diameter of a single tray. By stacking multiple trays vertically with pivotable connections, the system accommodates more optical fibre elements without increasing the lateral footprint. This dimensional transition maintains compactness and handling efficiency while achieving the goal of organizing a greater quantity of fibres.

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

3Ease of operation

If a bypass channel is used to guide optical fibre elements between trays, then fibre guidance is achieved, but device complexity and size increase

Engineering Contradiction:
Improvefibre guidanceVSAvoidbypass channel structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the fibre guidance function with the hinge connection structure itself. The hinge means, which provides pivotable support between trays, simultaneously serves as the guiding mechanism for optical fibre elements. The hinge's physical structure naturally directs fibres from the lower tray to the upper tray through its articulation point, eliminating the need for separate bypass channels. This merging of functions reduces device complexity while maintaining effective fibre guidance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hinge means performs multiple functions: it provides pivotable mechanical support between trays, enables independent access to each organizing area, and simultaneously guides optical fibre elements between the trays. By making the hinge structure multi-functional, the patent eliminates the need for dedicated bypass channels, reducing overall device complexity while achieving comprehensive fibre guidance capability.

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

AI summary

The present invention relates to an optical fibre tray assembly for organizing a plurality of optical fibre elements. The optical fibre tray assembly (1) comprises a lower tray (100) having a lower support plate (102) projected on a lower front surface side (104) thereof by a plurality of lower wall portions (106) forming a lower organizing area (108) for organizing at least one optical fibre element (111), and provided with a lower hinge means (118). The optical fibre tray assembly further comprises an upper tray (200) which has an upper support plate which provides an upper rear surface side (204) for covering partially the lower front surface side (104) of the lower tray (100) and which provides an upper front surface side (206) projected by a plurality of upper wall portions (208) forming an upper organizing area (210) for organizing at least one further optical fibre element (112), wherein the upper support plate (202) is projected laterally by upper hinge means (212). Said lower and upper hinge means (118; 212) cooperate with each other for pivotably connecting both trays (100, 200) with each other. The upper hinge means (212) provide a connection path (214) for guiding the at least one further optical fibre element (112) received by one of the lower tray (100) and the upper tray (200) toward the other tray (100; 200) thereof. Thereby, an improved optical fibre tray assembly may be provided, which allows an improved handling and organizing of the optical fibre elements.
