Stackable Optical Fibre Distribution Box for Flexible Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fibre distribution boxes are inadequate for managing increasing numbers of fibres in limited spaces, such as riser shafts, due to inflexible design and difficulty in assembly, which restricts fibre routing and connection options.
Innovation Solution
A modular optical fibre distribution box with stackable layers, allowing for flexible fibre routing and connection options, including a first layer for fibre reception and a second layer for distribution with adjustable orientations and built-in passive optical components, enabling efficient fibre redirection and splicing without requiring all functions in a single layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-layer optical fibre distribution box is used, then the structure is simple, but the flexibility in fibre routing and connection options is limited
Solution Approach 1:
The distribution box is divided into multiple stackable layers, each capable of independent configuration. The first layer receives fibres from the service provider cable, while the second layer distributes fibres to end users. This segmentation allows flexible fibre routing between layers without requiring a completely redesign of the entire distribution box structure.
Solution Approach 2:
The patent introduces vertical stacking of layers to add a third dimension to fibre routing. Instead of only horizontal routing options, fibres can now be routed vertically between stacked layers, providing additional routing paths and connection options while maintaining a compact footprint.
2Area of stationary object
If the distribution box is designed for compact space, then it fits well in riser shafts, but assembly becomes difficult in limited space
Solution Approach 1:
The distribution box is segmented into separate stackable layers that can be assembled independently. This allows workers to assemble each layer separately and then stack them vertically, which is much easier to do in limited space compared to assembling a complete single-layer box. The modular segments reduce the workspace requirements during assembly.
Solution Approach 2:
The layers are designed with pre-configured fibre routing channels and connection points. Fibres are pre-routed through the layers during manufacturing, so that during installation, workers only need to connect the layers together rather than routing fibres through the entire structure on-site. This preliminary action significantly simplifies field assembly.
3Quantity of substance
If more fibres are managed in the same space, then fibre capacity increases, but the number of operations required to manage those fibres increases dramatically
Solution Approach 1:
By dividing the distribution box into multiple layers, each layer can handle a specific subset of fibres. The first layer manages fibres from the service provider cable, while the second layer handles distribution to individual end users. This segmentation of fibre management tasks across layers reduces the operational complexity compared to managing all fibres in a single layer.
Solution Approach 2:
The vertical stacking of layers creates additional routing dimensions for fibre management. Instead of all fibres competing for horizontal routing space and connection points in a single plane, fibres are distributed across multiple vertical levels. This three-dimensional organisation reduces the number of operations required to manage high-density fibre configurations.
