Solution Overview
Problem
Existing sealing devices for lines passing through openings in walls face challenges with complex assembly processes and potential axial offsets of ring segments, leading to uneven sealing and reduced effectiveness.
Innovation Solution
A clamping device with ring segments that can be assembled into a single ring body via a plug-in receptacle and connecting part, preventing relative movement and ensuring uniform clamping force distribution, using a combination of hook parts and connecting elements for secure alignment and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate ring segments are used to form the clamping body, then the device can be assembled in sections, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The clamping body is divided into multiple ring segments that can be assembled separately and then connected to form a complete ring. This allows the device to be manufactured and transported in smaller sections while still achieving the full functional structure when assembled on-site.
Solution Approach 2:
The connecting part integrates multiple functions into a single component: it joins adjacent ring segments together, provides alignment features through plug-in receptacles, and ensures proper positioning. This merging of functions reduces the number of separate components needed and simplifies the overall assembly process.
2Ease of manufacture
If separate ring segments are used, then the device can be assembled in sections, but axial offsets between segments occur leading to uneven sealing
Solution Approach 1:
The connecting part features asymmetric plug-in receptacles that accept connecting elements at specific orientations. This asymmetric design ensures that ring segments can only be assembled in the correct orientation, preventing axial offsets and ensuring uniform contact pressure across the sealing surface.
Solution Approach 2:
The plug-in receptacle system replaces complex mechanical alignment and fastening systems. By using simple insertable connecting elements that guide and secure the ring segments, the design achieves precise alignment and uniform sealing without requiring complex adjustment mechanisms or multiple fastening steps.
3Stability of the object's composition
If ring segments are connected with connecting parts, then relative movement is prevented, but the device complexity increases
Solution Approach 1:
The connecting part is designed as a universal component that performs multiple functions: joining ring segments, providing alignment through plug-in receptacles, preventing relative movement, and ensuring proper orientation. This multi-functionality reduces the need for separate components for each function, thereby reducing overall device complexity despite the segmentation.
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 assembly, ensures uniform contact with the line and wall, and maintains an even seal by preventing axial and radial movement of ring segments, thus enhancing the sealing performance and reducing the risk of incorrect assembly.
Implementation Method 1
The sealing element is compressed in particular in the axial direction and at the same time expands in the radial direction. Due to the expansion in the radial direction, the inner surface of the sealing element is pressed onto the outer surface of the line and the outer surface is pressed against the wall of the opening.

AI summary
The invention relates to a device for sealing a pipe penetration through an opening in a wall area, comprising at least one sealing element (2) that can be arranged around the pipe, having an inner surface (4) for contacting the pipe and an outer surface (6) for contacting a wall bounding the opening, and a clamping device (8) for clamping the sealing element (2) so that the sealing element seals against the pipe with its inner surface (4) and against the wall with its outer surface (6), wherein the clamping device (8) has two clamping bodies (12, 12') arranged on both sides of the sealing element (2), the distance between which can be varied, wherein at least one of the clamping bodies (12, 12') has several ring segments (16', 16", 16‴) that can be assembled to form a ring body (16), wherein each ring segment is connected at its end to an adjacent ring segment via a connecting part (18, 18'). (16', 16",16‴) is reversibly connectable, wherein the ends of the ring segments (16', 16", 16‴) that can be connected by means of the connecting part (18, 18') each form a plug-in receptacle (20) for the connecting part (18, 18'). According to the invention, it is proposed that each ring segment (16', 16", 16‴) comprises at both ends a hook part (32, 32') open towards its outside for partially gripping the connecting part (18, 18') to which it can be connected.
