Active Valve Suspension Tuning for Dynamic Terrain Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle suspension systems face challenges in dynamically adjusting to varying terrain conditions, often resulting in either excessive stiffness leading to damage or insufficient damping causing damper failure, as current systems lack effective methods for real-time terrain adaptation.
Innovation Solution
An active valve system utilizing sensors to detect terrain conditions and adjust suspension characteristics in real-time, switching between firm and soft modes based on configurable thresholds and timers, with the ability to store and quickly switch between customizable 'tunes' using a smartphone app, and communicate settings wirelessly to the vehicle's controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If suspension is hardened to reduce vibration and shock, then ride stability improves, but risk of rim and frame damage increases
Solution Approach 1:
The patent implements dynamic suspension tuning through an active valve system that automatically adjusts damping characteristics in real-time based on terrain conditions. Sensors detect road surface variations and trigger valve adjustments to soften or firm the suspension as needed, replacing static manual tuning with dynamic adaptive control that optimizes both stability and damage prevention.
Solution Approach 2:
The system employs feedback mechanisms where sensors continuously monitor terrain conditions and suspension performance, feeding this information to the control system. The control system processes this data and adjusts valve positions accordingly, creating a closed-loop control system that automatically prevents damage while maintaining stability without requiring manual intervention.
2Ease of operation
If suspension is softened to improve comfort on rough terrain, then ride comfort improves, but risk of damper bottoming out increases
Solution Approach 1:
The active valve system dynamically adjusts damping force based on real-time terrain detection. When rough terrain is detected, the system softens the suspension to improve comfort; when approaching bottom-out conditions or encountering severe impacts, the system automatically firms up the suspension to prevent damage, creating a dynamic balance between comfort and protection.
Solution Approach 2:
The system takes preliminary anti-action by detecting terrain conditions before they cause damage. The sensors anticipate potential bottoming-out scenarios and pre-adjust the valve positions to increase damping force, preventing damper bottoming out before it occurs. This proactive approach maintains reliability while allowing comfort optimization.
3Adaptability or versatility
If manual suspension tuning is performed to optimize performance, then suspension characteristics improve, but system complexity and difficulty of adjustment increase
Solution Approach 1:
The system performs self-service by automatically tuning suspension characteristics without requiring user intervention. The control system autonomously processes sensor data, determines optimal damping settings, and adjusts valve positions accordingly. This eliminates the complexity of manual tuning while maintaining or improving suspension performance adaptability across different terrain conditions.
Solution Approach 2:
The patent replaces manual mechanical tuning with an electronic control system. Instead of requiring users to physically adjust valves and springs, the system uses electronic sensors, microcontrollers, and electrically actuated valves to automatically optimize suspension performance. This substitution reduces user burden while enhancing adaptability to varying terrain.
4Device complexity
If fixed suspension settings are used to simplify the system, then device complexity reduces, but adaptability to different terrain conditions deteriorates
Solution Approach 1:
The system transitions from static fixed settings to dynamic adaptive control. The active valve system continuously adjusts damping characteristics based on real-time terrain feedback, enabling the suspension to adapt to varying road conditions. This dynamic approach maintains relative system simplicity while dramatically improving terrain adaptability compared to fixed settings.
Solution Approach 2:
The control system provides universal adaptability by handling multiple terrain types and suspension scenarios through a single integrated system. The sensor array and control algorithm work together to recognize various terrain conditions and automatically select appropriate damping settings, making the system versatile across diverse operating conditions without requiring multiple separate tuning mechanisms.
