Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical fibre joint enclosures lack the capability to provide a compact, high-density solution for housing and protecting multiple optical fibre cables with multiple splice trays and ports, while also ensuring secure storage and environmental protection.
Innovation Solution
The optical fibre joint enclosure features a base housing and dome cover design with multiple storage baskets and splice trays, along with a port assembly that includes drop cable ports, primary ports, a mid-span port, earthing port, and an air valve, allowing for secure connection and storage of optical fibres in both indoor and outdoor settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional optical fibre joint enclosure designs are used, then the enclosure provides basic protection and storage, but the density and compactness are insufficient for high-capacity fibre storage
Solution Approach 1:
The patent implements nesting by placing multiple storage baskets (first basket, second basket, third basket) inside the base housing, with each basket containing multiple splice trays. This nested arrangement maximizes fibre storage capacity within a compact enclosure volume, achieving high density without increasing external dimensions.
Solution Approach 2:
The patent utilizes three-dimensional space efficiently by arranging storage baskets vertically and horizontally within the base housing. The dome cover encloses the entire assembly, creating a compact high-density enclosure that optimizes volume utilization through multi-dimensional positioning of storage components.
2Quantity of substance
If multiple splice trays and storage baskets are added to increase fibre capacity, then the storage density improves, but the device complexity increases
Solution Approach 1:
The patent divides the enclosure into modular components: base housing, dome cover, multiple storage baskets, and multiple splice trays per basket. This segmentation allows for systematic organization of fibres and simplifies installation, maintenance, and expansion while achieving high splice capacity.
Solution Approach 2:
The base housing serves multiple functions: providing structural support, containing storage baskets, offering environmental protection, and facilitating mounting. The dome cover provides both protection and a sealed enclosure. This multi-functionality reduces the need for additional specialized components, managing complexity while increasing capacity.
3Volume of moving object
If the enclosure is designed for high density and compactness, then space efficiency improves, but accessibility and ease of operation may be compromised
Solution Approach 1:
The removable storage baskets and splice trays enable easy access to fibres without requiring opening the entire enclosure. Operators can remove specific baskets or trays to access fibres, maintaining ease of operation while preserving the compact enclosed design for environmental protection.
Solution Approach 2:
The storage baskets and splice trays are designed to be removable and reconfigurable, allowing dynamic access to fibres. This enables operators to easily reach fibres in a compact enclosure without compromising the sealed protective structure, balancing compactness with operational ease.
4Reliability
If the enclosure provides comprehensive environmental protection, then reliability improves, but heat dissipation and air circulation may be restricted
Solution Approach 1:
The dome cover provides a sealed protective enclosure while allowing for thermal exchange. The enclosed design protects internal components from environmental conditions while maintaining adequate heat dissipation, ensuring reliable operation in various environmental conditions.
