Movable Mounting Assembly for Diesel Emissions Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diesel engine exhaust systems face challenges in mounting and accessing exhaust treatment components due to complexity and limited space, which obstructs maintenance and servicing, especially in field environments.
Innovation Solution
A mounting assembly with a platform and base frame configuration that allows the emissions control system to be positioned adjacent to a power source, with the platform being movable between positions to facilitate access and decoupling of exhaust treatment devices from the power source, enabling easy maintenance and compact mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If exhaust treatment components are mounted individually using individual brackets, then the components can be installed in the available space, but the mounting and interconnecting becomes difficult and obstructs access to engine components
Solution Approach 1:
The patent combines multiple individual mounting brackets into a single integrated mounting assembly that holds multiple exhaust treatment components (DPF, SCR, DOC) together. This merging reduces the number of separate mounting operations and simplifies the overall installation process while maintaining access to engine components by positioning the integrated assembly away from the engine.
Solution Approach 2:
The mounting assembly serves multiple functions simultaneously: it supports multiple exhaust treatment components, provides structural stability, enables easy installation and removal, and maintains proper spacing for access. This multi-functional design resolves the contradiction by making the mounting system itself capable of addressing both complexity and accessibility requirements.
2Ease of operation
If aftertreatment equipment is mounted in the vicinity of the engine, then the exhaust treatment is effective, but it results in difficulty in accessing the engine
Solution Approach 1:
The patent positions the mounting assembly in a three-dimensional space that optimizes both access and exhaust treatment effectiveness. By strategically locating the assembly away from the engine in available space and orienting it appropriately, the design creates spatial separation that allows engine access while maintaining effective exhaust treatment positioning.
3Area of stationary object
If multiple exhaust treatment components are mounted together, then space is utilized efficiently, but the complexity of mounting and interconnecting increases
Solution Approach 1:
The patent integrates multiple exhaust treatment components (diesel particulate filter, selective catalytic reduction device, diesel oxidation catalyst) into a single mounted assembly where they are positioned and secured together as one unit. This merging approach maximizes space utilization by consolidating components while reducing mounting complexity through a unified installation process rather than multiple separate operations.
Data Source
AI summary
An exhaust system is disclosed. The exhaust system may have an emissions control system including a mount and at least one exhaust treatment device secured to the mount. The exhaust system may also have a mounting assembly including a platform and a base frame. The emissions control system may be secured to the platform. The mounting assembly may be configured to position the emissions control system substantially adjacent to a power source. The platform may be movable relative to the base frame between a first position and a second position.
