Cable Penetration Seal Body With Angled Passages for Leak Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seal systems for elongate elements like cables or pipes passing through apertures fail to effectively prevent fluid or gas ingress/egress and contamination, especially when the element turns at the penetration, requiring an improved sealing mechanism that can adapt to various angles and sizes.
Innovation Solution
A seal system comprising a seal body with angled passages for cable penetration, enhanced thickness for secure sealing, and a fixing component with aligned apertures for secure attachment to the substrate, along with a lead-up component for cable protection and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a seal system allows an elongate element to pass through at an angle, then the cable can turn at the penetration, but the sealing effectiveness deteriorates due to gaps and misalignment
Solution Approach 1:
The seal body incorporates angled passages that extend through the side walls at specific angles relative to the central axis, allowing cables to pass through at non-perpendicular angles while maintaining sealing effectiveness. This dimensional adaptation enables the seal to accommodate cable turns without compromising the sealing barrier.
Solution Approach 2:
The seal body features localized sealing lips positioned at the angled passages where cables penetrate. These sealing lips are specifically placed at the cable-contact zones to maintain sealing effectiveness at the critical penetration points, while other portions of the seal body maintain their structural sealing function against the surface.
2Reliability
If the seal body is made thicker to improve sealing, then sealing reliability improves, but the device complexity and installation difficulty increase
Solution Approach 1:
The seal system is divided into distinct components: a seal body with integrated angled passages, a separate fixing component with alignment apertures, and optional lead-up components. This segmentation allows the thick seal body to be installed as part of a modular system, reducing overall installation complexity while maintaining the sealing reliability provided by the substantial seal body thickness.
3Reliability
If multiple sealing lips are added to seal against surface and cable, then sealing effectiveness improves, but the manufacturing complexity increases
Solution Approach 1:
Multiple sealing lips are integrated into the seal body as single monolithic structures rather than separate components. The sealing lips are formed as integral parts of the molded seal body, combining multiple sealing functions into one manufacturing process. This approach maintains sealing effectiveness while simplifying manufacturing compared to assembling multiple separate sealing elements.
4Ease of operation
If aligned apertures are provided for fasteners, then installation ease improves, but the structural integrity may be compromised
Solution Approach 1:
The fixing component serves multiple functions: it provides alignment apertures for easy fastener installation, distributes mechanical loads across the seal body, and maintains the positional integrity of the seal system. By consolidating these functions into a single component, the design achieves installation ease without compromising the overall structural integrity of the sealed assembly.

AI summary
This invention relates to a seal system for sealing between an elongate element such as a cable and a surface or substrate around an aperture in the surface through which the elongate element passes. The seal system comprises a seal body to surround the aperture and seal against the surface or substrate around the aperture. The seal body comprises at least one passage for penetration of the elongate element through the seal body at a side of the seal body. The at least one passage providing for a seal to the elongate element. Also provided is a fixing component adapted to be attached over at least part of the seal body and/or through the seal body to seal with the surface or substrate.
