Exhaust Pipe Mounting via Compensation Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs with vertically extending components like exhaust pipes face challenges due to massive and costly frame structures, which are prone to damage from vibrations and oscillations, and require complex fastening solutions to manage relative movements between the cab and chassis, leading to increased weight and installation complexity.
Innovation Solution
A double indirect fastening system with a compensation device mounted via a bearing in the driver's cab and another on the chassis, decoupling the exhaust pipe from direct cab movements and rotations, allowing it to be indirectly supported, reducing leverage forces and enabling flexible movement compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a massive frame structure is used to fixedly mount the exhaust pipe to the chassis, then the exhaust pipe is securely held, but the weight and cost of the fastening structure increase significantly
Solution Approach 1:
The patent applies dynamics by allowing the exhaust pipe to move relative to the chassis through a telescopic compensation device. Instead of rigidly fixing the exhaust pipe to the chassis with a massive frame, the system enables controlled movement along the longitudinal axis while maintaining secure mounting. The compensation device absorbs relative movements and vibrations, providing reliable mounting without requiring excessive structural mass.
2Stability of the object's composition
If a massive frame structure is used to fixedly mount the exhaust pipe, then mounting stability is improved, but the complexity of assembly and installation increases
Solution Approach 1:
The patent applies segmentation by dividing the mounting system into separate functional components: a mounting bracket attached to the chassis, a telescopic compensation device with adjustable length, and connection points on the exhaust pipe. This modular segmentation allows each component to perform its specific function independently, simplifying assembly and installation while maintaining mounting stability through the coordinated operation of these segmented elements.
3Strength
If the exhaust pipe is rigidly fixed to the chassis, then structural support is maximized, but damage from vibrations and oscillations increases
Solution Approach 1:
The patent applies the intermediary principle by introducing a telescopic compensation device as a mediator between the exhaust pipe and the chassis. This compensation device acts as an intermediary element that absorbs and dampens vibrations and oscillations transmitted from the chassis to the exhaust pipe. The telescopic mechanism with controlled play provides structural support while simultaneously protecting the exhaust pipe from vibration-induced damage through this intermediary buffering layer.
4Ease of manufacture
If the exhaust pipe is mounted directly to the driver's cab, then installation is simplified, but large transition requirements between exhaust gas pot and exhaust pipe arise
Solution Approach 1:
The patent applies the extraction principle by removing the exhaust pipe mounting from direct attachment to the driver's cab and instead anchoring it to the chassis. This extraction of the mounting point eliminates the need for complex transition structures between the exhaust system and the cab. The exhaust pipe can be positioned and adjusted independently through the telescopic compensation device mounted on the chassis, simplifying both installation and the transition design between exhaust components.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the weight and cost of the fastening structure, minimizes damage from vibrations, and simplifies the installation by distributing acceleration forces effectively between the cab and chassis, while maintaining the stability of the exhaust pipe during vehicle movements.
Implementation Method 1
the compensation device is used to compensate for relative rotations and/or relative movements between the driver's cab and the exhaust pipe
Implementation Method 2
a double indirect fastening of the exhaust pipe on the one hand to the driver's cab and on the other hand to the chassis is proposed. In order to absorb the weight and/or the acceleration forces from the exhaust pipe towards the rest of the vehicle or vice versa
