Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved designs in splice closure systems that provide efficient storage and management of excess optical fiber lengths while ensuring a minimum bend radius is maintained to prevent damage and signal loss, and for mechanical connections that facilitate easy and reliable coupling of optical components.
Innovation Solution
A telecommunications enclosure with a management unit featuring a support infrastructure that includes a pivotable rear tray for excess fiber storage, a pivot interlock mechanism for smooth tray pivoting, and a mechanical connection interface that allows intuitive coupling and decoupling of structural elements, along with a cable sealing arrangement using gel sections to accommodate cable deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional cable sealant arrangement is used, then the cable entry port can accommodate standard cable sizes, but it cannot effectively seal smaller fiber optic cables without creating excessive gaps that compromise sealing effectiveness
Solution Approach 1:
The patent applies local quality by providing different port size reducers for different cable diameters. Each reducer is specifically designed to match a particular cable size, creating a localized adaptation that ensures optimal sealing for each cable type while maintaining overall system versatility
Solution Approach 2:
The port size reducers are nested within the cable access ports of the sealant arrangement. The reducers fit inside the ports, creating a nested structure where the reducer acts as an inner component that modifies the port's internal geometry to accommodate smaller cables while maintaining the outer port structure
2Reliability
If gel sealant is used to fill cable access ports, then sealing can be achieved, but the gel may be extruded during cable installation causing mess and potential damage
Solution Approach 1:
The port size reducers are pre-installed in the cable access ports before cable installation. This preliminary action creates a prepared sealing environment where the gel sealant is contained within the reducer structure, preventing extrusion during cable installation while maintaining sealing effectiveness
3Ease of manufacture
If a single large cable port is used, then installation is simple, but it cannot provide secure sealing for multiple different cable sizes
Solution Approach 1:
The patent segments the cable access ports by introducing separate port size reducers for different cable sizes. Each reducer is a distinct component that can be selectively installed in specific ports, allowing the system to handle multiple cable sizes while maintaining the simplicity of the overall port structure
