ATV Canister Layout in Triangular Body Cover Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing layout configurations for fuel tank canisters in all-terrain vehicles, particularly when enlarged, face challenges in securing space on the front side of the steering mechanism, limiting the degree of freedom in layout and affecting the adsorption efficiency due to space constraints and potential temperature increases from direct sunlight.
Innovation Solution
The design incorporates a body cover with a vertical wall, an upper wall, and an inclined connection wall forming a triangular accommodation space for the canister, which enhances layout flexibility and protection, while a metallic label helps in utilizing space and reducing temperature rises. Additionally, the canister is positioned to align with the vehicle's width direction, and a detachable box-shaped case facilitates maintenance and appearance quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the canister is disposed on the front side of the steering mechanism as in prior art, then the layout is simplified, but the degree of freedom in layout is limited and space is insufficient when the canister size is enlarged
Solution Approach 1:
The invention transitions from a conventional horizontal layout (front side of steering mechanism) to utilizing vertical and angular spaces. Specifically, the canister is disposed in a triangular accommodation space formed by the body cover's vertical wall, upper wall, and connection wall, effectively using the third dimension (vertical space) and angular regions to achieve flexible layout while accommodating larger canister sizes
2Ease of manufacture
If the canister is disposed on the front side of the steering mechanism, then installation is simplified, but the canister is exposed to direct sunlight causing temperature rise that reduces adsorption efficiency
Solution Approach 1:
The invention converts the harmful effect of direct sunlight exposure into a beneficial protective feature. The metallic label on the body cover is positioned to intercept direct sunlight, preventing it from reaching the canister. This transforms the potential harm (sunlight exposure causing temperature rise) into a benefit (sunlight interception protecting the canister), thereby maintaining adsorption efficiency while keeping the canister in an accessible position
3Quantity of substance
If the canister size is enlarged to enhance adsorption capacity, then the adsorption efficiency is improved, but securing space for the canister becomes more difficult in conventional layouts
Solution Approach 1:
The invention creates sufficient space for enlarged canisters by utilizing the triangular accommodation space formed by the body cover's vertical wall, upper wall, and connection wall. This triangular space, positioned between the body cover corner and the specified wheel, provides adequate volume for larger canister sizes while maintaining proper integration with the vehicle structure

AI summary
An all terrain vehicle includes: an internal combustion engine; a fuel tank; a body frame on which to mount the engine and tank; at least three wheels suspended at the frame and including at least paired left and right wheels; and a canister adsorbing evaporated fuel in the tank. Part of a body cover includes: a vertical wall extending up-down while covering a specified wheel from one of front and rear sides; an upper wall covering the specified wheel from above, extending forward and rearward, and spaced toward an other of the front and rear sides from the vertical wall; and a connection wall inclined while interconnecting an end portion on the vertical wall side of the upper wall and an upper end of the vertical wall. An accommodation space triangular in side view is formed between the connection wall and specified wheel. The canister is disposed in the space.
