Exhaust Component Mounting Structure for Single-Crane Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-scale exhaust after-treatment systems for engines, such as those in locomotives and marine applications, require complex and time-consuming servicing due to the size and weight of components, often necessitating multiple cranes for component removal, which increases downtime and costs.
Innovation Solution
The exhaust after-treatment system incorporates load-bearing and non-load-bearing mounting structures that allow each component section to support adjacent sections, eliminating the need for multiple cranes during servicing by distributing the weight and providing robust structural support through mounting structures attached to load-bearing flanges and surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If exhaust after-treatment components are made larger to handle more exhaust emissions, then the system can adequately treat emissions from large-scale applications, but the components become heavier and require multiple cranes for removal during servicing
Solution Approach 1:
The exhaust after-treatment system is divided into multiple separable components (e.g., catalyst assemblies, particulate filters) that can be independently removed and serviced. Each component is designed with its own mounting structure that allows it to be detached from the main system, enabling selective removal without requiring lifting of the entire system.
Solution Approach 2:
Mounting structures with lifting eyes or attachment points are introduced as intermediary elements between the heavy exhaust components and the cranes. These mounting structures are specifically designed to provide secure attachment points that distribute the weight and enable safe lifting operations with single crane operations.
2Quantity of substance
If exhaust after-treatment components are made larger to treat more emissions, then the system can handle larger engine applications, but the time required for servicing increases due to the need for multiple cranes
Solution Approach 1:
The system is segmented into modular components that can be independently accessed and removed. This modular architecture allows technicians to service only the specific component that needs maintenance without disassembling the entire exhaust after-treatment system, significantly reducing servicing time.
Solution Approach 2:
Mounting structures are pre-configured with lifting eyes and attachment points during manufacturing, so that components are ready for quick removal and installation. This preliminary preparation eliminates the need for complex assembly procedures during servicing operations.
3Strength
If multiple cranes are used to remove heavy exhaust components, then the components can be safely lifted, but the complexity and cost of the servicing operation increases
Solution Approach 1:
Mounting structures with integrated lifting eyes and attachment points serve as intermediaries that enable single-crane operations. These structures are designed to distribute the weight of heavy components and provide secure attachment points, allowing one crane to safely lift and move components that would otherwise require multiple cranes.
Solution Approach 2:
The mounting structures are designed with counterbalancing features and weight distribution mechanisms that offset the weight of the exhaust components, making them manageable with single-crane operations. The mounting structures themselves are engineered to bear the load and provide mechanical advantage.
4Quantity of substance
If exhaust after-treatment components are made larger for bigger engines, then more emissions can be treated, but the difficulty of detecting and measuring during servicing increases
Solution Approach 1:
The exhaust after-treatment system is divided into modular, separable components with standardized mounting structures. This segmentation allows each component to be independently accessed, removed, and serviced, making inspection and measurement operations much easier compared to integrated systems.
Solution Approach 2:
Mounting structures are positioned at strategic locations that provide access to components from multiple spatial dimensions. This allows servicing personnel to approach components from various angles and directions, improving accessibility and making detection and measurement operations easier.

AI summary
An exhaust after-treatment system includes an exhaust inlet, an exhaust outlet, and an array of exhaust treatment components disposed in a housing. The housing includes a first connection flange securing the housing to the inlet, a second connection flange securing the housing to the outlet, and a third flange positioned between the first and second flanges. A mounting device is secured to the third flange to independently support the housing relative to the inlet and the outlet.
