Variably Damped Solenoid Valve for Stable Shock Fluid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suspension systems for vehicles lack the ability to dynamically adjust damping characteristics in real-time to accommodate varying terrain and riding conditions, leading to suboptimal comfort and performance.
Innovation Solution
A variably damped flow control solenoid is introduced, which uses a solenoid to adjust the position of an armature relative to a plate with a pin, controlling the fluid pathway and thereby modifying the damping characteristics of the shock assembly, allowing for real-time adjustments to fluid flow and damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed damping valve is used in the shock assembly, then the structural simplicity is maintained, but the ability to adapt to varying terrain and riding conditions deteriorates
Solution Approach 1:
The patent applies the Dynamics principle by implementing a solenoid-controlled armature mechanism that dynamically adjusts the valve opening position. The armature moves between a first position (restricting flow) and a second position (allowing free flow) based on solenoid activation, enabling real-time adaptation of damping characteristics to varying terrain and riding conditions while maintaining a relatively simple overall system structure.
2Speed
If the valve opens quickly to allow free fluid flow, then the response speed is improved, but pressure waves and fluid instability worsen
Solution Approach 1:
The patent applies the Dynamics principle by creating a controlled, progressive opening mechanism. The armature transitions from a first position to a second position through a controlled movement that regulates fluid flow incrementally. This dynamic positioning system allows the valve to respond quickly to control signals while maintaining fluid stability by avoiding sudden, uncontrolled opening that would generate harmful pressure waves.
3Productivity
If the armature is fully unseated to maximize fluid flow, then the productivity is improved, but the control precision and damping adjustment capability worsen
Solution Approach 1:
The patent applies the Dynamics principle by implementing a multi-position armature control system. Rather than simply fully seated or fully unseated, the armature can be positioned dynamically between a first position (restricting flow for precise damping control) and a second position (fully unseated for maximum fluid flow). This dynamic positioning capability enables the system to achieve both high productivity when needed and precise damping adjustment when required, depending on operating conditions.
