Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration damping systems for transport equipment, such as vehicles and ships, are inadequate in addressing extreme low-frequency high-amplitude vibrations and fail to provide self-balancing capabilities, especially under complex road conditions where up-down movement, pitch, and roll coexist.
Innovation Solution
A self-balancing vibration damping system that includes a control module, sensor module, active vibration damping module with first and second rotating assemblies, and a receiving module, which synchronously controls the receiving module to roll and pitch, achieving two degrees of freedom and maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If active suspension is provided, then vibration damping effect is improved, but self-balancing function is lacking and cost increases
Solution Approach 1:
The patent integrates multiple functions into a single vibration damping system. The active vibration damping system simultaneously provides vibration suppression and self-balancing capabilities by detecting the transport equipment's attitude and vibration characteristics through sensors and coordinating the damping forces to achieve both objectives with one unified system.
Solution Approach 2:
The system uses onboard sensors to automatically detect vibration and attitude deviations, then the control system autonomously adjusts the damping forces without external intervention. The system serves itself by using its own sensor data to generate the appropriate damping response, eliminating the need for separate control systems.
2Ease of operation
If mechanical means and passive vibration damping are used for balance, then one degree of freedom is realized, but complex road conditions with up-down movement, pitch, and roll cannot be solved
Solution Approach 1:
The patent replaces purely mechanical balancing mechanisms with an active control system that uses sensors and controllable damping elements. Instead of relying on fixed mechanical structures, the system uses electronically controlled damping forces that can adapt to complex multi-directional vibrations from uneven roads, providing superior performance over mechanical-only solutions.
Solution Approach 2:
The system transitions from static mechanical balancing to dynamic active control. The damping coefficients are continuously adjusted based on real-time vibration and attitude data, enabling the system to handle complex road conditions with simultaneous up-down movement, pitch, and roll that fixed mechanical systems cannot accommodate.

Function Achieved in This Case
The system effectively reduces both high-frequency low-amplitude and low-frequency high-amplitude vibrations, achieving a self-balancing vibration damping effect that maintains the transport equipment and its occupants in a stable state.
Implementation Method 1
The control module is configured to control the first rotating assembly and the second rotating assembly to operate synchronously according to the motion data to provide an inertial force opposite to a tilt direction of the receiving module
