Hood Support Assembly Integrating DOC Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting assemblies for diesel oxidation catalyst (DOC) modules in work vehicles are complex, difficult to assemble, and inefficiently utilize the limited under-hood space, making it challenging to mount and maintain these components.
Innovation Solution
A hood support assembly with a support frame, angled mounting brackets, and a removable mounting cradle that accommodates the DOC module and other under-hood components, allowing for efficient installation and removal without requiring the hood or other components to be removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional mounting assembly is used for the DOC module, then the DOC module can be mounted under the hood, but the assembly becomes complex and difficult to assemble, significantly increasing assembly times
Solution Approach 1:
The hood support assembly is designed to perform multiple functions: it supports the vehicle hood, mounts the DOC module, and provides structural support for other under-hood components. By integrating these functions into a single assembly, the patent eliminates the need for separate mounting brackets and reduces overall complexity while decreasing assembly time.
Solution Approach 2:
The patent combines the hood support function with the DOC module mounting function into a single integrated assembly. The hood support assembly includes mounting features that directly attach the DOC module, merging two previously separate functions into one unified structure, thereby simplifying the overall mounting system.
2Loss of energy
If the DOC module is mounted as close as possible to the engine, then heat loss is minimized, but the large size of the DOC module makes it difficult to fit within the limited under-hood space
Solution Approach 1:
The hood support assembly utilizes the vertical dimension and three-dimensional space under the hood more efficiently. By designing the assembly to extend vertically and utilize available space in multiple dimensions rather than only horizontal placement, the DOC module can be positioned close to the engine while accommodating its large size within the constrained under-hood environment.
3Adaptability or versatility
If conventional mounting assemblies are used, then the DOC module can be supported, but the assemblies do not provide efficient mounting solutions for other under-hood components, wasting limited storage space
Solution Approach 1:
The hood support assembly is designed as a universal mounting platform that can accommodate not only the DOC module but also other under-hood components such as the air intake system and battery. The assembly includes multiple mounting points and brackets that can be configured to support various components, maximizing the utilization of limited under-hood space.

AI summary
A hood support assembly for a work vehicle may generally include a support frame having a front support arm, a rear support arm and a hood support plate coupled between the front and rear support arms. The support frame may further include a first mounting bracket and a second mounting bracket extending inwardly from the front and rear support arms, respectively. The hood support assembly may also include a removable mounting cradle coupled between the first and second mounting brackets. The mounting cradle may include a first mounting flange configured to be coupled to the first mounting bracket and a second mounting flange configured to be coupled to the second mounting bracket. The mounting cradle may be configured to vertically support an exhaust treatment component of the work vehicle between the front and rear support arms.
