Vehicle Rear End Plate Mounting via Trim Panel Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting systems for end plates of exhaust gas systems in motor vehicles add weight and influence vibrations, complicating the assembly and stability of the vehicle rear region.
Innovation Solution
The end plate is decoupled from the end pipes and mounted directly in the trim panel, which is securely attached to the bumper via supports, reducing assembly complexity and ensuring vibration-free mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the end plate is mounted in the end pipe of the exhaust gas system, then the exhaust gas system is supported, but the weight of the end plate influences the end pipe and causes vibrations
Solution Approach 1:
The mounting system is segmented into three independent components: the bumper, the trim panel, and the end plate. The end plate is separated from the end pipe and mounted exclusively in the trim panel, while the end pipe remains suspended and vibration-free. This segmentation eliminates the harmful coupling between the heavy end plate and the sensitive end pipe.
Solution Approach 2:
The trim panel acts as an intermediary structure that carries the end plate's weight away from the end pipe. The supports connect the trim panel to the bumper, creating a load path that bypasses the end pipe entirely. This intermediary structure resolves the contradiction by providing support stability without transmitting weight-induced vibrations to the end pipe.
2Stability of the object's composition
If the end plate is mounted in the end pipe, then the exhaust gas system is stabilized, but the assembly complexity increases
Solution Approach 1:
The assembly is divided into independent modules that can be installed separately. The trim panel with pre-mounted supports forms one module, the end plate forms another, and the end pipe forms a third. This modular segmentation simplifies assembly by allowing each component to be prepared and installed independently, reducing overall assembly complexity.
Solution Approach 2:
The supports are pre-mounted on the bumper before the trim panel is installed. This preliminary action prepares the mounting structure in advance, so that when the trim panel is placed onto the bumper, the supports are already in position to receive and secure the end plate, streamlining the assembly process.
3Stability of the object's composition
If the trim panel is securely attached to the bumper via supports, then the end plate mounting becomes vibration-free, but the structure requires additional components
Solution Approach 1:
The supports serve multiple functions: they structurally connect the trim panel to the bumper for structural integrity, and they provide mounting points for securing the end plate to the trim panel. This multi-functionality achieves vibration-free end plate mounting without requiring separate dedicated mounting components, thereby avoiding increased structural complexity.
