Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing press seal systems require specialized knowledge and tools for assembly, particularly in ensuring the correct torque for clamping the elastomer body, which can be challenging for installers like electricians, and limit flexibility in routing lines of different diameters and angles.
Innovation Solution
A press seal system with a decoupled sealing element that can be independently sealed against a line using a clamp, allowing for easier installation and accommodating varying line diameters and angles, while the elastomer body is braced against the reveal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elastomer body is clamped to seal against the jamb, then sealing against the jamb is achieved, but the installation requires specialized knowledge and tools with specific torque limits
Solution Approach 1:
The sealing system is divided into two independent sealing elements: the elastomer body for sealing against the jamb and the separate sealing element for sealing against the pipe. This segmentation allows each element to be installed and sealed independently, eliminating the need for specialized torque control during installation.
Solution Approach 2:
The sealing function against the pipe is extracted from the elastomer body and implemented by a separate sealing element. This extraction removes the complexity of coordinating two sealing functions within a single clamped component, simplifying the installation process while maintaining reliable sealing.
2Reliability
If the inner circumferential surface of the elastomer body is used to seal against the pipe, then sealing is achieved, but the pipe routing is limited to predefined axially parallel paths
Solution Approach 1:
The sealing element is designed with dynamic adaptability to accommodate pipes routed at various angles. Unlike the rigid inner circumferential surface of the elastomer body that dictates axially parallel routing, the separate sealing element can adapt to diagonal or angled pipe paths, providing routing flexibility while maintaining the sealing effect.
3Reliability
If the elastomer body is clamped with high force to ensure sealing, then sealing reliability is improved, but the elastomer body may be damaged
Solution Approach 1:
The sealing function is segmented between the elastomer body and a separate sealing element. The sealing element is specifically designed to be pressed against the pipe with appropriate force, while the elastomer body is clamped only to the extent needed for jamb sealing, preventing excessive force that could damage the elastomer body.
4Device complexity
If a single compression seal system is used for both jamb and pipe sealing, then device complexity is reduced, but installation requires specialized tools and knowledge
Solution Approach 1:
The sealing system uses two separate sealing elements (elastomer body and sealing element) that can be installed independently. This segmentation, while slightly increasing structural components, dramatically simplifies installation by eliminating the need for specialized torque-controlled clamping tools and knowledge, as each element can be sealed with simple pressing actions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the installation process by allowing electricians to easily route cables through a grommet-shaped sealing part, enabling angled or curved line routing and accommodating different line diameters without the need for specialized tools or knowledge.
Implementation Method 1
the elastomer body can be clamped, i.e., compressed axially. As a result of the axial compression, the elastomer body expands radially
Implementation Method 2
the sealing element can, for example, extend axially away from the elastomer body in the form of an elastomer sleeve and then be pressed against the pipe

AI summary
The invention relates to a compression sealing system for insertion into an opening (3) and sealing the opening (3) against a pipe, wherein the compression sealing system has an elastomer body (1) for clamping in the opening (3) and a sealing element (2) which is decoupled from the clamping of the elastomer body (1) in such a way that it is radially more deformable than the elastomer body (1), at least in the clamped state of the elastomer body (1), so that the sealing element (2) can be sealed against the pipe even when the elastomer body (1) is already clamped.
