Cable Drop Sealing Assembly with Nested Sleeves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data center cable management, existing systems fail to effectively seal cables as they are routed from troughs into cabinets, leading to air leakage and potential damage from rough edges, which affects both temperature control and cable protection.
Innovation Solution
A sealing assembly comprising a base mounted to a network cabinet, a hingedly connected cover, a lower sleeve, and an upper sleeve, utilizing flexible materials and hook-and-loop fasteners to secure cables and minimize air loss, while providing bend radius control and protection against edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are routed directly from troughs into cabinets without sealing, then cable installation is simple and quick, but air leakage occurs and cables are exposed to damage from rough edges
Solution Approach 1:
The sealing assembly uses nested sleeves (upper sleeve containing lower sleeve) that fit within each other to provide multi-layer protection for cables. The inner sleeve provides primary protection while the outer sleeve reinforces the sealing and protection, creating a nested structure that enhances cable protection without requiring completely separate components.
Solution Approach 2:
The sealing assembly is divided into multiple functional segments: a base mounted to the cabinet, upper and lower sleeves for different levels of protection, and a hinged cover for access. This segmentation allows each component to perform its specific function (sealing, protection, access) while working together as an integrated system.
2Temperature
If a sealing assembly is installed to prevent air leakage, then temperature control improves, but the device complexity and installation difficulty increase
Solution Approach 1:
The cover is hinged rather than fixed, allowing it to be dynamically opened for cable installation and maintenance access, then closed to maintain the seal for temperature control. This dynamic design enables the assembly to switch between open and closed states, providing both installation ease and operational sealing.
Solution Approach 2:
The sealing assembly incorporates flexible grommets and sleeve materials that can adapt to cable bundles of varying sizes and configurations. These flexible components deform to accommodate cables while maintaining the seal, making installation easier without compromising temperature control effectiveness.
3Reliability
If rigid protective structures are used to protect cables from rough edges, then cable protection improves, but the risk of cable damage during installation increases
Solution Approach 1:
The sealing assembly uses flexible grommets and sleeve materials that provide protection from rough edges while remaining soft and compliant during cable installation. These flexible protective elements conform to the cables and prevent mechanical damage that would occur with rigid protective structures.
Solution Approach 2:
The sealing assembly is pre-installed with flexible protective grommets and sleeves in positions where cables will pass through, providing cushioning protection before cables are installed. This beforehand cushioning prevents cables from contacting rough edges during the installation process itself.

AI summary
The present invention is directed toward a sealing assembly in a cable drop system. The sealing assembly includes a base mounted to a network cabinet and a cover hingedly connected to the base. The sealing assembly also includes a lower sleeve and an upper sleeve. The lower sleeve and the upper sleeve wrap around the cables passing through an opening in the cable drop system. The lower sleeve includes a top portion and a bottom portion. The bottom portion of the lower sleeve is connected to the base and the upper sleeve is positioned around the top portion of the lower sleeve to form the sealing assembly.
