Integrated Damping Force Structure With Adjustable Valve Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing damping force generation structures in hydraulic shock absorbers require an external adjustment member to adjust the interval between the valve body and valve seat, increasing the number of components and manufacturing costs, while also being prone to variations in dimensional tolerances affecting damping force characteristics.
Innovation Solution
A damping force generation structure that integrates a damping force generation mechanism and a damping force adjustment mechanism via a fixing member, with a drive mechanism and coupling member, allowing for position adjustments of the valve body using a position adjustment mechanism, such as female and male threads, to adjust the damping force without external components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an external adjustment member is used to adjust the interval between the valve body and valve seat, then the damping force characteristics can be adjusted, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The patent combines the adjustment member with the valve body into a single integrated component. The adjustment member is formed as an integral part of the valve body, eliminating the need for separate external adjustment components. This merging reduces the total number of components while maintaining the damping force adjustment capability through the integrated structure.
2Adaptability or versatility
If an external adjustment member is used to adjust the interval between the valve body and valve seat, then the damping force characteristics can be adjusted, but manufacturing cost increases
Solution Approach 1:
The adjustment member is integrated into the valve body as a single component, reducing the number of parts that need to be manufactured, assembled, and quality-checked. This integration simplifies the manufacturing process and reduces assembly operations, leading to lower manufacturing costs while preserving the damping force adjustment functionality.
3Ease of manufacture
If dimensional tolerances of individual components are allowed to vary, then manufacturing is easier, but the interval between the valve body and valve seat varies affecting damping force characteristics
Solution Approach 1:
By forming the adjustment member as an integral part of the valve body, the patent eliminates the need for precise clearance control between separate components. The integrated structure ensures consistent geometric relationships regardless of individual component tolerances, as there are no separate mating surfaces requiring tight tolerance control. This maintains interval consistency while allowing standard manufacturing tolerances.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the number of components needed to adjust the damping force, allowing for consistent damping force characteristics by adjusting the position of the valve body relative to the valve seat, thereby maintaining design dimensions and reducing manufacturing costs.
Implementation Method 1
The damping force adjustment mechanism includes an electromagnetic coil, a conductive annular member, and a shaft member fixed to the annular member. When electricity is supplied to the electromagnetic coil, a magnetic field is generated, the shaft member moves together with the annular member in a direction along an axis of the shaft member

AI summary
A damping force generation structure includes a damping force generation mechanism, and a damping force adjustment mechanism. The damping force adjustment mechanism includes a drive mechanism configured to be able to drive the valve body, and a coupling member having a first end fixed to the drive mechanism and a second end fixed to the fixing member, thereby coupling the drive mechanism and the fixing member. At least one of a position of the damping force generation mechanism relative to the fixing member, a position of the coupling member relative to the fixing member, and a position of the drive mechanism relative to the coupling member is adjustable in the advancing and retracting direction of the valve body by a position adjustment mechanism.
