Solution Overview
Problem
The existing methods for connecting exhaust gas treatment devices to pipe sections in internal combustion engine exhaust systems require significant effort and manufacturing costs due to the need for strong clamp connections and additional support pipes to ensure alignment and rigidity.
Innovation Solution
A funnel-pipe arrangement with a connection piece having axially open openings and a clamping collar system, where the pipe is fastened to the funnel using a clamp connection with a ring-shaped body, eliminating the need for an additional support pipe and simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support pipe is added to ensure alignment and rigidity of the clamp connection, then the connection reliability is improved, but the device complexity and manufacturing effort increase
Solution Approach 1:
The invention extracts and eliminates the unnecessary support pipe from the system. By analyzing the actual functional requirements, it determines that the support pipe is not essential for achieving reliable alignment and rigidity. The clamp connection can achieve sufficient stability through proper design of the connection piece and pipe geometry alone, thereby removing the additional component and simplifying the overall device.
Solution Approach 2:
The invention merges the alignment and connection functions into a single integrated clamp connection system. Instead of having separate support structures and connection mechanisms, the design integrates the alignment features directly into the connection piece and pipe interface, allowing one component to perform multiple functions that were previously distributed across several parts.

3Manufacturing precision
If additional support structures are added to ensure proper alignment, then the alignment precision is improved, but the manufacturing effort increases
Solution Approach 1:
The invention implements self-service alignment where the connection piece and pipe are designed with inherent geometric features that automatically guide and align the components during assembly. The tapered surfaces and complementary geometries enable the parts to self-align without requiring additional support structures or complex alignment procedures, making the assembly process intuitive and efficient.
Solution Approach 2:
The invention incorporates preliminary alignment features directly into the design of the connection piece and pipe. The tapered surfaces and geometric configurations are pre-configured to provide guidance and positioning before the final clamping action occurs, ensuring proper alignment is achieved as part of the natural assembly sequence rather than requiring separate alignment steps.

Function Achieved in This Case
This solution provides a rigid and stable connection between the pipe and the funnel, reducing manufacturing costs and effort while ensuring proper alignment and sealing, even under high pressures.
Implementation Method 1
The clamp connection has a clamp, which has a ring-shaped connecting body, which extends over the clamping collar and the counterclamping collar and prestresses same axially towards one another
