Swingable Shock Absorber Cover for Debris Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle suspension device protection structures fail to effectively prevent collisions with mud, stones, and sand from the road surface and require labor-intensive maintenance to detach protective covers.
Innovation Solution
A protection structure for a vehicle suspension device where an absorber cover is attached to the suspension arm, allowing it to swing and cover the shock absorber from the outer peripheral side, preventing collisions and allowing easy attachment and detachment without removing the shock absorber, along with additional features like a mud flap and scraper to manage debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover is attached to the shock absorber, then the protection performance is improved, but the maintainability deteriorates because the coil spring must be removed to detach the cover
Solution Approach 1:
The protective cover is segmented into two attachment options: it can be attached to the shock absorber for maximum protection, or detached and attached to the vehicle body for easier maintenance. This segmentation allows the system to switch between protection mode and maintenance mode, resolving the contradiction between protection performance and maintainability.
Solution Approach 2:
The attachment position of the protective cover is made dynamic rather than fixed. The cover can be moved between two attachment points (shock absorber and vehicle body), allowing the system to adapt its configuration based on whether protection or maintenance is the priority, thus resolving the contradiction.
2Ease of repair
If the absorber cover is attached to the suspension arm, then the maintainability is improved, but the coverage range may be reduced
Solution Approach 1:
The attachment system is segmented to allow the cover to be detached from the suspension arm and reattached to the vehicle body when maximum coverage is needed. This segmentation enables the system to switch between easy maintenance mode and maximum protection mode, resolving the contradiction between maintainability and coverage range.

AI summary
A protection device of a vehicle suspension device includes a vehicle body frame, a wheel, a knuckle that rotatably supports the wheel, a suspension arm that connects the vehicle body frame and the knuckle and is configured to be swingable up and down along with up-and-down movement of the wheel with an end portion attached to the vehicle body frame being a pivot point, a shock absorber that has an upper end attached to the vehicle body frame and a lower end attached to the suspension arm, and is configured to buffer swinging movement in an up-and-down direction of the suspension arm, and an absorber cover attached to the suspension arm and covering a periphery of the shock absorber.
