Tail Pipe Assembly Wave-Shaped Water Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles with GDI engines generate soot-laden condensation water in mufflers, which contaminates the ground when drained, as existing tail pipe assemblies fail to effectively collect and store this water, leading to pollution.
Innovation Solution
A tail pipe assembly with a main collecting element and collecting plates that cover the interior circumference, featuring a larger mounting portion and wave-shaped designs, to suppress and temporarily store condensation water, delaying its discharge and preventing ground contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If condensation water is drained directly from the muffler, then the exhaust system operates continuously, but the ground becomes contaminated with soot-laden water
Solution Approach 1:
The tail pipe assembly incorporates a water collection reservoir and wave-shaped collecting elements that preliminarily capture and store condensation water before it can be discharged. The wave-shaped structure creates multiple water traps that hold soot-laden condensate, preventing its direct release onto the ground while maintaining continuous exhaust operation.
Solution Approach 2:
The tail pipe assembly acts as an intermediary device between the muffler and the ground. It introduces a water collection and storage mechanism that mediates the discharge path of condensation water, separating the exhaust flow from the harmful condensate to prevent ground contamination.
2Object-affected harmful factors
If a water collection device is added to the tail pipe, then ground contamination is prevented, but the device complexity increases
Solution Approach 1:
The collecting elements utilize wave-shaped thin wall structures that are formed integrally with the tail pipe. These flexible, thin-film-like wave structures create water trapping zones without requiring heavy or complex components, achieving water collection while maintaining structural simplicity.
Solution Approach 2:
The wave-shaped collecting elements introduce curved, undulating surfaces within the tail pipe assembly. These curved structures naturally trap water through their geometry, creating storage zones without complex mechanical parts. The curvature of the wave patterns provides effective water collection while keeping the overall design simple and integrated.
