Adjustable Shock Absorber Control for Real-Time Ride Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle suspension systems require vehicles to be stopped for adjustments, limiting real-time adjustments to terrain and payload conditions, and lack the ability to make on-the-go adjustments for optimal ride comfort.
Innovation Solution
The system allows for real-time, on-the-go adjustments to shock absorbers' damping characteristics using electronically controlled valves and sensors, enabling operators to alter compression and rebound damping while driving, using a controller and user interface for optimal ride comfort based on sensor inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional manual adjustment methods are used for shock absorbers, then adjustment capability is provided, but the vehicle must be stopped and tools are required, reducing productivity and ease of operation
Solution Approach 1:
The patent replaces manual mechanical adjustment tools with an electronically controlled system. The controller receives signals from the user interface and automatically adjusts the shock absorber parameters through electronic actuators, eliminating the need for manual tools and reducing adjustment time while maintaining full adjustment capability.
Solution Approach 2:
The system enables self-service adjustment where the operator can control shock absorber parameters directly through the user interface without requiring external tools or assistance. The electronic system automatically executes adjustments based on user input, making the adjustment process independent and rapid.
2Adaptability or versatility
If adjustable shock absorbers are provided, then ride comfort can be optimized, but adjustments require stopping the vehicle, limiting adaptability to changing terrain and payload conditions
Solution Approach 1:
The patent implements dynamic adjustment capability where shock absorber parameters can be changed while the vehicle is in motion. The electronic control system allows continuous modification of damping characteristics in response to changing terrain and payload conditions, eliminating the need to stop the vehicle for adjustments and maintaining operational continuity.
3Extent of automation
If electronic control systems with sensors and valves are implemented, then real-time damping control is achieved, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional controller that integrates multiple control functions into a single device. The controller manages shock absorber adjustment, receives inputs from the user interface, and coordinates valve actuation, thereby reducing the number of separate components needed and simplifying the overall system architecture despite maintaining advanced automation capabilities.

AI summary
A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame includes at least one adjustable shock absorber having an adjustable damping profile and a driver actuatable input. The driver actuatable input may be positioned to be actuatable by the driver in the absence of requiring a removal of either of the hands of the driver from a steering device of the vehicle.
