Modular Shock Absorber Pressure Valve for Opening Pressure Variants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pre-controlled pressure regulation valves for hydraulic shock absorbers require complex configurations and multiple components to achieve varying opening pressures, leading to increased costs and manufacturing complexities in producing variants for different applications.
Innovation Solution
A modular pressure regulation valve design featuring a pilot stage module and an actuator module, interconnected via a press connection, allowing for adjustable positioning and simplified mounting, which reduces variance in opening pressure and facilitates the production of variants by swapping individual function modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional non-modular pressure regulation valves are used to achieve different opening pressures, then various shock absorber applications can be served, but the device complexity and manufacturing cost increase due to requiring multiple complete valve variants
Solution Approach 1:
The pressure regulation valve is divided into separate functional modules: a main stage module and a pilot stage module. The pilot stage module can be exchanged independently to achieve different opening pressures, while the main stage module remains constant. This segmentation allows versatility in opening pressure selection without increasing overall valve complexity.
2Adaptability or versatility
If multiple complete valve variants are produced for different opening pressures, then different shock absorber applications are covered, but the manufacturing cost increases
Solution Approach 1:
By segmenting the valve into reusable main stage module and exchangeable pilot stage modules, the manufacturing cost is reduced. Only the smaller pilot stage modules need to be produced in multiple variants, while the more expensive main stage module is manufactured once and reused across all variants.
Solution Approach 2:
The main stage module is designed with universal functionality that can work with multiple different pilot stage modules. This multi-functionality allows a single main stage module to serve multiple applications by simply changing the pilot stage module, thereby reducing the total number of components that need to be manufactured.
3Stability of the object's composition
If the pilot stage module and actuator module are rigidly connected, then the structure is stable, but the positioning precision and mounting simplicity decrease
Solution Approach 1:
The connection between the pilot stage module and actuator module is made adjustable rather than rigid. The pilot stage module can be positioned at different locations on the actuator module and fixed in place, allowing for dynamic adjustment of the connection point to achieve optimal positioning precision while maintaining operational stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular design enables cost-effective formation of variants with reduced variance in opening pressure, simplified mounting, and easy adaptation to different parameters and applications, while maintaining robustness and compactness.
Implementation Method 1
The pilot stage valve itself is readjusted by means of an electromagnetic actuator
Implementation Method 2
The pilot stage valve controls the pressure on at least one side of the main stage valve and thereby is in a position to produce fluid-dynamical forces in the main stage, which operate the main stage valve
