ATV Front Cover with Shock Absorber Visibility Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles capable of running on uneven terrain face challenges in improving front visibility while maintaining an increased stroke for front wheel shock absorbers, as raising the upper end of the shock absorber interferes with the front cover and reducing the front cover's position for better visibility is difficult.
Innovation Solution
A vehicle design featuring a front cover with a sloped portion and openings that allow the upper end of the shock absorbers to be visible, enabling the front cover to be positioned lower for improved visibility while maintaining an extended stroke for the shock absorbers, and incorporating a modular front cover structure for easy maintenance and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the position of the upper end portion of the shock absorber is raised to elongate the stroke, then the stroke of the shock absorber is improved, but the front cover position must be raised which deteriorates front visibility
Solution Approach 1:
The front cover is divided into a main body portion and a separate lower portion that can be independently positioned. The lower portion is configured to be lower than the main body portion, creating a stepped structure that allows the shock absorber upper end to be visible through the opening in the main body while maintaining a low overall front cover position for improved visibility.
Solution Approach 2:
The front cover is designed with a multi-level vertical structure rather than a single flat plane. The lower portion extends below the main body portion in the vertical dimension, creating space for the shock absorber to extend its stroke while the front cover maintains a low profile for visibility.
2Illumination intensity
If the position of the front cover is lowered to improve front visibility, then front visibility is improved, but the stroke of the shock absorber is limited
Solution Approach 1:
The front cover is segmented into a main body portion and a lower portion positioned at different heights. The opening in the main body portion allows the shock absorber to extend its stroke above the main body level while the lower portion maintains the overall low position of the front cover for improved visibility.
Solution Approach 2:
The lower portion is nested below the main body portion of the front cover, creating a layered structure where the shock absorber can extend through the opening in the main body while the lower portion remains positioned low for visibility, effectively nesting the shock absorber path within the front cover structure.
3Device complexity
If the front cover is made integral with the shock absorber housing, then structural simplicity is maintained, but maintenance and adjustment of the shock absorber become difficult
Solution Approach 1:
The front cover is segmented into a main body portion and a separate lower portion connected by a connection portion. This segmentation allows the shock absorber to be accessed and maintained by working on the lower portion independently, while the main body portion remains structurally simple and integrated with the vehicle body.
Solution Approach 2:
The connection portion acts as an intermediary element between the main body portion and the lower portion, providing a accessible interface for maintenance and adjustment operations while maintaining the overall structural integrity and simplicity of the front cover assembly.

AI summary
An ROV (Recreational Off-highway Vehicle) includes a plurality of seats located next to each other in a vehicle width direction, a left shock absorber, a right shock absorber, and a front cover. An opening is provided in the front cover. An upper end portion of the left shock absorber and an upper end portion of the right shock absorber are visible within the opening when the vehicle is seen from above.
