Vehicle Height Adjustment Damper Rod Rotation Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle height adjustment systems face issues with increased manufacturing costs due to a large number of parts and the lack of a separate device to prevent damper rod rotation, which can degrade the durability of the damper rod and affect vehicle stability.
Innovation Solution
A vehicle height adjustment system that includes a cylinder housing part, a piston part, a damper rod part with a protrusion, and a guide part to suppress rotational movement, along with a rotation suppressing bracket to prevent unnecessary rotation of the damper rod, thereby reducing the number of parts and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional damper rod is used without a separate rotation prevention device, then the device complexity is reduced, but the damper rod rotates unnecessarily which degrades its durability
Solution Approach 1:
The rotation prevention function is merged into the guide part that is already present in the piston assembly. The guide part includes a groove structure that receives the protrusion on the damper rod, combining rotation prevention with the existing guidance function without adding separate components.
Solution Approach 2:
A protrusion is added to the damper rod that serves as an intermediary element engaging with the groove in the guide part. This protrusion-groove interface prevents rotation of the damper rod while maintaining linear movement, solving the rotation problem through a simple geometric intermediary rather than a complex mechanical device.
2Adaptability or versatility
If air suspension is used to maintain vehicle height, then vehicle height can be constantly maintained or adjusted, but the number of parts increases including air compression devices
Solution Approach 1:
The suspension system uses the existing hydraulic pressure from the shock absorber's working fluid to automatically adjust and maintain vehicle height. The system serves itself by utilizing the inherent pressure fluctuations during compression and extension cycles rather than requiring external air compression devices and active control systems.
Solution Approach 2:
The invention employs hydraulic principles where the working fluid in the shock absorber creates pressure that automatically adjusts the suspension height. The hydraulic system replaces the need for pneumatic air suspension components, using fluid pressure instead of compressed air to achieve height maintenance and adjustment.
