Sound Damper Connection Pipe With Integrated Wall Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound damper connection pipes in exhaust gas systems are difficult to support stably and require complex connections to the sound damper housing, leading to potential instability and noise issues.
Innovation Solution
The sound damper connection pipe is integrated as an integral component of an intermediate wall within the sound damper housing, using a support element that is part of the intermediate wall to provide stable support without additional connections, with optional welding for added stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the sound damper connection pipe is supported on the sound damper housing with additional connection measures, then the stability of the pipe is improved, but the structural complexity increases
Solution Approach 1:
The support element is merged with the intermediate wall to form an integral component, eliminating the need for separate support structures. The intermediate wall and support element are produced as a single piece, combining the functions of structural division and pipe support into one element, thereby reducing overall structural complexity while maintaining stability.
Solution Approach 2:
The intermediate wall serves multiple functions: it subdivides the housing interior into chambers for exhaust gas flow management and simultaneously provides the support element for the connection pipe. This multi-functionality reduces the number of separate components needed, simplifying the overall structure while ensuring stable pipe support.
2Object-generated harmful factors
If the sound damper connection pipe is fixed with additional connection measures, then the noise-free operation is improved, but the manufacturing complexity increases
Solution Approach 1:
The support element is integrated into the intermediate wall as an integral component, meaning they are produced as a single piece rather than assembled from separate parts. This merging eliminates the need for additional connection operations such as welding or fastening, thereby reducing manufacturing complexity while ensuring stable, noise-free operation.
Solution Approach 2:
The intermediate wall with its integrated support element provides self-supporting functionality, eliminating the need for external connection measures. The structure serves itself by incorporating the support function directly into the wall, reducing manufacturing steps and ensuring stable operation without additional assembly operations.
3Adaptability or versatility
If the support element is made as a separate component, then the adaptability is improved, but the structural complexity increases
Solution Approach 1:
The support element is merged with the intermediate wall to form an integral component that is produced as a single piece. This integration maintains adaptability because the support element can still be designed with various geometries and configurations to accommodate different pipe positions and orientations, while the merged structure reduces overall complexity by eliminating separate components and assembly steps.

AI summary
A sound damper for an exhaust gas system of an internal combustion engine includes a sound damper housing, at least one intermediate wall which is arranged in a housing interior and at least one sound damper connection pipe. The sound damper connection pipe is supported in a first pipe end region on the sound damper housing and is arranged in a second pipe end region on a support element which is arranged in the housing interior. The support element forms an integral component of an intermediate wall. The sound damper connection pipe introduces exhaust gas into the housing interior or directs exhaust gas out of the housing interior.
