Exhaust Pipe Seal Assembly With Visible Installation Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting fluid-conducting components in motor vehicle exhaust systems do not allow for a straightforward visual verification of seal installation after clamping, requiring disassembly for confirmation.
Innovation Solution
Incorporating a visible flag on the seal that protrudes from the connection point and is visible through the clamp's parting line, along with a mandrel and lug for precise alignment, ensuring the seal is correctly positioned and visible post-assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal is installed between fluid-conducting components and fastened with a clamping collar, then the connection is sealed and secure, but it becomes impossible to visually verify whether the seal was installed without disassembling the connection
Solution Approach 1:
The seal includes a flag element that changes its visibility state based on installation. When the seal is properly installed between the flanged connection elements, the flag protrudes and becomes visible through the clamping collar's opening. This visual indicator allows verification of seal installation without disassembly, resolving the contradiction between reliable verification and structural simplicity.
2Stability of the object's composition
If the clamping collar is designed to encircle both components securely, then the connection is stable, but the seal installation status cannot be detected from the outside
Solution Approach 1:
The flag on the seal acts as an intermediary indicator between the sealed connection and the external observer. The flag's protrusion through the clamping collar's opening provides visual information about the seal's installation status without compromising the stability and integrity of the enclosed connection structure.
3Reliability
If the connection is designed for secure fastening, then assembly is reliable, but verification of proper assembly requires time-consuming disassembly
Solution Approach 1:
The seal's flag automatically provides verification information as part of the installed connection structure. The flag's visibility through the clamping collar allows the connection itself to communicate its proper assembly status without requiring additional verification steps or disassembly, eliminating time loss while maintaining assembly reliability.

AI summary
The invention relates to an arrangement (100) for connecting a first fluid-conducting component (110) to a second fluid-conducting component (120), more particularly in the exhaust gas line of a motor vehicle, having a seal (130), which seals the components (110, 120) at the connecting point, and having a band clamp (140), which encloses the components (110, 120) at the connecting point and attaches the components (110, 120) to each other. According to the invention, the seal (130) is formed with a tab (131), which protrudes at the connecting point after the components (110, 120) have been connected and is visible through a separation joint (141) of the band clamp (140). The invention further relates to a corresponding method for connecting a first fluid-conducting component (110) to a second fluid-conducting component (120).
