Solution Overview
Problem
Existing shock absorbers have a narrow adjustment range and poor adjustment effect, making it difficult to achieve the optimal hardness for different vehicles, affecting vehicle stability and comfort.
Innovation Solution
An adjustment device with a body, adjustment inner gear ring, and shaft that allows for a wide range of hardness adjustments by varying the cross-sectional areas of adjustment holes, enabling the flow rate of oil to be adjusted, thus modifying the shock absorber's hardness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the adjustment device uses a small diameter adjustment inner gear ring, then the device complexity is reduced, but the adjustment range becomes narrow and the adjustment effect becomes poor
Solution Approach 1:
The patent transitions from a small diameter adjustment inner gear ring to a large diameter adjustment inner gear ring. This dimensional change allows for more adjustment holes to be arranged along the circumferential direction, thereby expanding the adjustment range and improving the adjustment effect without significantly increasing device complexity.
2Object-affected harmful factors
If the shock absorber is made softer, then the vehicle body bounce is reduced, but the vehicle stability deteriorates
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that allows the shock absorber hardness to be changed according to different driving conditions. By rotating the adjustment shaft, users can select different adjustment holes with varying cross-sectional areas, thereby dynamically adjusting the oil flow rate and shock absorber hardness to simultaneously reduce vehicle body bounce and maintain vehicle stability.
3Stability of the object's composition
If the shock absorber is made harder, then the vehicle stability is improved, but the spring working efficiency deteriorates
Solution Approach 1:
The patent enables dynamic adjustment of shock absorber hardness through the adjustment device. When vehicle stability is needed, harder shock absorber settings can be selected; when spring working efficiency is prioritized, softer settings can be chosen. This dynamic adaptability resolves the contradiction between vehicle stability and spring working efficiency.
4Manufacturing precision
If the adjustment holes have uniform cross-sectional area, then the manufacturing precision is easier to control, but the adjustment effect becomes poor
Solution Approach 1:
The patent applies local quality by making each adjustment hole have a different cross-sectional area. The adjustment inner gear ring includes multiple adjustment holes with varying sizes, allowing different oil flow rates and providing finer control over shock absorber hardness adjustment, thereby improving the adjustment effect.
