Snowmobile Bumper Mount Segmentation for Hood Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current snowmobile designs face challenges in integrating lightweight, durable, and efficient air intake systems that effectively cooperate with bumpers and hoods, while also providing convenient access to under-hood components and storage solutions.
Innovation Solution
A hood assembly with an airbox featuring a plenum, multiple branches, baffles, and a quarter wave chamber, along with a bumper mount and latch assembly that allows for secure attachment of bumpers and hoods to the snowmobile frame, facilitating easy access and storage solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bumper is mounted directly to the frame, then the structure is simple, but the bumper cannot be easily removed or replaced
Solution Approach 1:
The bumper mounting system is divided into separate components: the bumper itself, the bumper mount, and the frame. This segmentation allows the bumper to be independently removed from the frame while keeping the mount structure in place, enabling easy replacement without affecting the overall vehicle structure.
Solution Approach 2:
The bumper mount incorporates movable or adjustable elements that allow the bumper to be easily attached and detached. This dynamic design enables the bumper to transition between secured and removable states, providing operational flexibility while maintaining structural integrity when mounted.
2Ease of operation
If the airbox assembly is integrated with the hood, then access to under-hood components is convenient, but the structural integrity may be compromised
Solution Approach 1:
The airbox assembly is designed as a separate, removable component from the hood structure. This segmentation allows the airbox to be independently accessed and removed for under-hood component access, while the hood retains its structural integrity as a separate load-bearing element.
Solution Approach 2:
The airbox assembly serves as an intermediary component that provides access to under-hood areas without requiring hood removal. It acts as a mediator between the external environment and internal components, allowing maintenance access while the hood remains securely attached to the frame.
3Adaptability or versatility
If the airbox provides both air intake and storage functions, then the device is more versatile, but the air intake efficiency may be reduced
Solution Approach 1:
The airbox is divided into distinct functional zones: an air intake section with optimized airflow paths and a storage section for accessories. This segmentation allows air to flow efficiently through dedicated channels while storage compartments are positioned in areas that do not interfere with the airflow path, maintaining both functions without compromising performance.
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
The solution enhances air intake efficiency, reduces throttle noise, provides secure attachment of components, and offers convenient access to under-hood areas, improving the overall performance and usability of snowmobiles.
Implementation Method 1
A quarter wave chamber may also be positioned within the plenum
Implementation Method 2
the air box assembly provides air-silencing capabilities by damping throttle noise produced by the throttle body assembly

AI summary
An assembly for a snowmobile includes an airbox having a plenum for coupling to a throttle body of an engine and two branches defining openings for air intake. A storage box is mounted between the two branches and defines area for receiving a console. The airbox is part of a hood of the vehicle and includes an opening over a storage box. The disclosure also includes a ribbed bumper mount with a latch assembly for securing the hood.
