Integrated Soft Valve Port for Compact Shock Absorber Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional damping force variable valve assemblies have a complex assembly process and increased size due to separate port and soft valve parts, leading to higher part counts and reduced assembly ease.
Innovation Solution
An integrated soft valve port with a valve disk and a hollow cylindrical valve housing, where the valve disk is stacked and the connection passages are formed outside a fitting hole, allowing for a reduced part count and simplified assembly, while maintaining stability within the valve housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the port and soft valve parts are provided separately, then the assembly process becomes complex and the size increases, but the sealing between components can be maintained
Solution Approach 1:
The patent integrates the port and soft valve parts into a single integrated soft valve port component. The soft valve body is formed with an integrated structure that includes the connection passage and valve seat, eliminating the need for separate port components and reducing the number of parts that need to be assembled.
Solution Approach 2:
The integrated soft valve port performs multiple functions within a single component: it provides the connection passage for fluid flow, forms the valve seat for the valve disk, and maintains sealing functions. This multi-functional design reduces assembly complexity while maintaining all necessary functions.
2Reliability
If the port and soft valve parts are provided separately, then the sealing between components can be maintained, but the overall size of the valve assembly increases
Solution Approach 1:
By merging the port and soft valve parts into a single integrated component, the overall volume of the valve assembly is reduced. The integrated structure eliminates the need for additional sealing interfaces between separate components, thereby reducing the total space required while maintaining sealing reliability through the integrated design.
3Reliability
If the port and soft valve parts are provided separately, then the sealing between components can be maintained, but the number of parts increases
Solution Approach 1:
The patent combines multiple separate parts (port, soft valve body, connection passage, valve seat) into a single integrated soft valve port component. This reduces the total number of parts that need to be manufactured, stored, and assembled, while the integrated structure maintains all necessary sealing functions within the single component.

AI summary
Disclosed is a damping force variable valve assembly including: an integrated soft valve port having one end connected to a shock absorber, a connection passage with a working fluid flowing therethrough from the shock absorber, and a valve disk provided at a bottom surface of the integrated soft valve port to be in close contact therewith; a valve housing having a hollow cylindrical shape, and having an inner circumferential surface of a front end coupled to an outer circumferential surface of the integrated soft valve port; and a main valve part disposed underneath the integrated soft valve port in the valve housing.
