Exhaust Isolator Direct Mounting System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional exhaust mounts or isolators for vehicles require extensive hardware such as brackets, bolts, and nuts for attachment to the frame, increasing construction and assembly costs and carbon usage.
Innovation Solution
A direct mounting system for exhaust isolators to the vehicle's frame or underbody, eliminating the need for upper brackets and associated hardware, using a press-fit mechanism with a sleeve and elastomeric isolator that accepts a support rod for secure positioning of the exhaust system components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional exhaust mounts use brackets, bolts, and nuts for attachment to the frame, then the exhaust system can be securely mounted, but the construction and assembly costs increase and carbon usage increases
Solution Approach 1:
The patent combines the mounting bracket, isolator mounting surface, and isolator into a single integrated exhaust isolator component. The housing directly contacts the frame to provide mounting while the elastomeric isolator provides vibration isolation, eliminating the need for separate brackets and fasteners.
Solution Approach 2:
The patent extracts and eliminates the unnecessary hardware components (brackets, bolts, nuts, weldments) from the traditional mounting system, retaining only the essential functions through integration into the exhaust isolator housing and elastomeric isolator assembly.
2Reliability
If traditional exhaust mounts use extensive hardware for attachment, then secure mounting is achieved, but manufacturing costs increase
Solution Approach 1:
The patent merges multiple discrete components (mounting bracket, isolator, fasteners) into a single integrated exhaust isolator assembly, reducing manufacturing steps, inventory requirements, and assembly operations while maintaining mounting security.
Solution Approach 2:
The exhaust isolator housing is designed to self-mount directly to the frame through direct contact surfaces, and the elastomeric isolator self-secures within the housing, eliminating the need for external fasteners and complex assembly procedures.
3Shape
If traditional exhaust mounts use brackets and hardware, then the exhaust system can be positioned, but the amount of carbon necessary for construction increases
Solution Approach 1:
The patent removes unnecessary metal hardware components (brackets, bolts, nuts, weldments) that contribute to carbon footprint, replacing them with a streamlined integrated design that uses only essential materials for mounting and isolation functions.
Solution Approach 2:
The patent changes the material and structural parameters by using a lightweight housing design with direct frame contact surfaces and an elastomeric isolator, replacing heavy metal hardware with optimized structural elements that achieve positioning with minimal material usage.
Applied Scientific Principles
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 manufacturing costs and carbon usage by eliminating unnecessary hardware while ensuring effective isolation of engine vibrations and proper positioning of the exhaust system, simplifying the assembly process and enhancing system durability.
Implementation Method 1
the elastomeric isolator includes an exterior housing or sleeve, an elastomeric isolator disposed within the exterior housing or sleeve
Implementation Method 2
In order to prevent engine movement and/or vibrations from being transmitted to the vehicle's body, the exhaust mounts or isolators incorporate flexible mounting members or elastic suspension members to isolate the vehicle's body from the exhaust system
Implementation Method 3
using a press-fit mechanism with a sleeve and elastomeric isolator that accepts a support rod for secure positioning
