Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for supporting exhaust aftertreatment devices on vehicles face challenges in alignment and secure mounting, leading to difficulties in vehicle construction and assembly.
Innovation Solution
A mounting interface system comprising first and second mounting brackets, apertures, bushings, and fasteners, where the bushings and apertures are shaped to facilitate alignment and secure attachment of the exhaust aftertreatment device to a vehicle frame, utilizing torque-accepting devices for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing mounting methods are used for exhaust aftertreatment devices, then the device can be mounted on the vehicle, but alignment and secure mounting become difficult, leading to assembly complexities
Solution Approach 1:
The patent introduces mounting brackets with bushings as intermediary components between the exhaust aftertreatment device and the vehicle frame. The brackets provide alignment features and the bushings facilitate precise positioning, thereby simplifying the assembly process while ensuring secure mounting. This intermediary structure resolves the contradiction by adding components that make alignment and mounting easier rather than more complex.
2Manufacturing precision
If existing mounting methods are used for exhaust aftertreatment devices, then the device can be attached to the vehicle frame, but alignment becomes difficult, leading to difficulties in vehicle construction
Solution Approach 1:
The mounting brackets are pre-equipped with alignment features and bushings before the final assembly. This preliminary preparation of alignment mechanisms in the mounting brackets enables precise positioning of the exhaust aftertreatment device during installation, thereby improving manufacturing precision while actually simplifying the vehicle construction process rather than complicating it.
3Ease of operation
If simple mounting structures are used, then assembly is easier, but secure fixation and stable positioning cannot be ensured
Solution Approach 1:
The mounting system is segmented into multiple functional components: mounting brackets, bushings, and fasteners. Each component performs a specific function - the brackets provide structural support and alignment, the bushings facilitate precise positioning, and the fasteners ensure secure fixation. This segmentation allows for easier assembly while maintaining stable positioning, as each component can be optimized for its specific purpose rather than requiring a single complex structure to do everything.
