Variable Cable Seal Assembly for Multi-Diameter Cabinet Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic equipment cabinets face challenges in repairing or replacing parts and cables without replacing large portions of the cabinet, and they struggle to accommodate cables of different sizes while maintaining a fluid-resistant seal.
Innovation Solution
A variable size seal system with multiple seal sections of different internal diameters, allowing for flexible selection and installation to accommodate cables of varying sizes, and an entry module assembly that enables cable entry without disconnecting cables from connection points, using a flange section for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single size seal is used for each cable size, then a fluid-resistant seal can be provided, but inventory complexity and cost increase due to needing multiple seal sizes
Solution Approach 1:
The seal is designed with multiple seal sections of different internal diameters integrated into a single component. Each seal section can accommodate a different cable size, allowing one seal to serve multiple functions and replace the need for multiple separate seals of different sizes.
Solution Approach 2:
The seal is divided into multiple seal sections, each with a different internal diameter configured for a specific cable size. These sections are arranged concentrically or in sequence, allowing selective use of appropriate seal sections for different cable diameters while maintaining a unified seal structure.
2Reliability
If the cabinet construction provides a fluid-resistant barrier, then cable and equipment protection is improved, but repair and replacement of parts and cables becomes difficult or impossible without replacing large portions of the cabinet
Solution Approach 1:
The seal is designed as a removable component that can be detached from the cabinet without removing or damaging the cabinet structure itself. This segmentation allows the seal to be independently replaced or adjusted while preserving the integrity of the cabinet and its fluid-resistant barrier functionality.
Solution Approach 2:
The seal incorporates flexible or adjustable elements that allow it to adapt to different cable sizes and configurations. This dynamic capability enables the seal to maintain its fluid-resistant function while accommodating cable replacements or repairs without requiring cabinet modification.
3Stability of the object's composition
If the cabinet portion at cable entry location cannot be removed without disconnecting cables, then structural integrity is maintained, but removal or replacement becomes difficult and time consuming
Solution Approach 1:
The seal is designed as a separate, removable component that interfaces with the cabinet at the cable entry location. This allows the seal to be detached and replaced independently from the cabinet structure, eliminating the need to disconnect cables from internal connection points or compromise cabinet structural integrity.
Solution Approach 2:
The seal function is extracted from the cabinet structure itself and implemented as a separate, standalone component. This extraction allows the seal to be removed, replaced, or adjusted without affecting the cabinet's structural integrity or requiring cable disconnection from internal connections.
4Reliability
If different size seals are used to accommodate cables of different sizes, then proper sealing is achieved, but the variety of seal sizes required increases inventory cost and complexity
Solution Approach 1:
A single seal component incorporates multiple seal sections with different internal diameters, each designed to accommodate a specific cable size. This universal seal can be used for all cable sizes, eliminating the need to maintain separate inventory of multiple seal sizes.
Solution Approach 2:
Multiple seal sections of different sizes are combined into one integrated seal component. The different seal sections are arranged to work together, allowing a single seal to provide appropriate sealing for various cable diameters that would otherwise require separate seal components.

AI summary
A seal may include a first seal section defining a first internal cylindrical surface defining a first internal diameter configured to provide a substantially fluid-resistant seal between the first internal cylindrical surface and an external surface of a cable. The seal may also include a second seal section coupled to the first seal section and defining a second internal cylindrical surface defining a second internal diameter configured to provide a substantially fluid-resistant seal between the second internal cylindrical surface and an external surface of a cable, wherein the first internal diameter and the second internal diameter may differ from one another. An entry module assembly for facilitating entry of one or more cables into an enclosure may include an entry module plate defining an aperture configured to receive a cable therethrough, and a seal coupled to the entry module plate and extending through the aperture of the entry module plate.
