Removable Sealed Cable Passage Insert for Gas-Tight Partitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable grommets in the maritime and construction fields face challenges in maintaining both tightness and flexibility, as traditional solutions either damage the seal when removing cables or fail to provide sufficient tightness for gas-tight applications.
Innovation Solution
A device featuring a permanently fastened frame with a removable insert moulded to fit the longitudinal element, allowing easy addition and removal of cables while ensuring a sealed connection, and utilizing a spacer ring for enhanced adhesion and seal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a retractable membrane controlled by a clamping device is used to allow cable addition/removal, then ease of operation is improved, but tightness and reliability deteriorate
Solution Approach 1:
The device is divided into a permanent frame and a removable insert. The insert contains the sealing structure and can be independently removed and replaced, while the frame remains permanently fixed to the partition. This segmentation allows the sealing function to be maintained while enabling easy cable management operations.
Solution Approach 2:
The removable insert is extracted as a separate component that can be removed from the frame. This extraction allows cables to be added or removed by simply taking out the insert, manipulating cables, and reinserting the same or a different insert, without damaging any sealing structure.
2Reliability
If sealing material is poured to fill the hole volume, then tightness is improved, but ease of operation deteriorates
Solution Approach 1:
The sealing function is segmented into the removable insert rather than being permanently integrated into the partition. This allows the seal to be maintained when the insert is in place, while enabling easy removal and reinstallation for cable management operations.
Solution Approach 2:
The insert is pre-formed with the sealing material already integrated into its structure. This preliminary preparation allows the seal to be automatically re-established simply by inserting the component, without requiring on-site sealing operations.
3Reliability
If the frame is permanently fastened to the partition, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The device is segmented into a permanent frame (fastened to partition) and a removable insert. This segmentation allows the frame to provide stable, reliable mounting while the insert handles the operational requirements of cable management.
Solution Approach 2:
The operational component (insert) is extracted as removable, while the mounting structure (frame) remains permanently fixed. This extraction enables cable operations without requiring detachment of the entire assembly from the partition.

AI summary
Disclosed is a device for the sealed passage of at least one longitudinal element through a through-hole provided in a partition, including—a frame capable of being permanently fastened in a sealed manner on the partition in order to delimit the hole,—a removable insert, of which at least a central portion is produced by moulding on the longitudinal element in order to produce a sealed connection with the latter, the removable insert being configured to be inserted in a removable and sealed manner in the frame.
