Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern mobile machinery, particularly agricultural sprayers with elongated booms, experience structural oscillations due to high winds, vibrations, and terrain variations, leading to fatigue and potential load failure, which are exacerbated by traditional solutions like using heavier materials that increase cost and energy consumption.
Innovation Solution
Implement sensors to capture oscillation data, analyze it to detect symmetric and asymmetric oscillations, and generate damping signals that modify vehicle speed and steering commands to reduce these oscillations, using a control unit to combine these signals with existing control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavier materials are used to reduce oscillations, then structural strength and stability are improved, but weight and energy consumption increase
Solution Approach 1:
The patent replaces the traditional mechanical solution of using heavier materials to reduce oscillations with an electronic control system. Sensors detect oscillations and a control system generates damping signals that modify vehicle speed and steering commands, substituting active electronic control for passive mechanical reinforcement.
Solution Approach 2:
The system implements feedback control by continuously monitoring oscillations with sensors and adjusting vehicle operation in real-time. The control system processes sensor data to detect oscillations and generates damping signals that are combined with existing control signals, creating a closed-loop feedback mechanism that actively counteracts oscillations without adding structural weight.
2Stability of the object's composition
If heavier materials are used to reduce oscillations, then structural stability is improved, but energy consumption increases
Solution Approach 1:
The patent replaces the energy-intensive approach of using heavier materials with an electronic control system that consumes minimal energy. The system uses sensors to detect oscillations and processes this data to generate damping signals, substituting low-energy electronic control for high-energy mechanical reinforcement.
Solution Approach 2:
The feedback control system continuously monitors and adjusts vehicle operation to dampen oscillations, providing structural stability through active control rather than passive mass. This real-time adjustment mechanism maintains stability while consuming significantly less energy than transporting heavier materials.
3Reliability
If sensors and control systems are added to dampen oscillations, then oscillation reduction effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where sensors mounted on the vehicle capture oscillation data, the control system processes this data to detect oscillations, and damping signals are generated and combined with existing control signals. This integrated feedback mechanism provides effective oscillation reduction through coordinated sensor and control system operation.

AI summary
Described herein are systems, methods, and other techniques for damping oscillations of an implement of a vehicle while the vehicle is moving. Sensor data is captured using one or more sensors that are attached to the vehicle. The sensor data is analyzed to extract one or both of symmetric oscillation information or asymmetric oscillation information. One or both of a speed damping signal or a steering damping signal are generated based on analyzing the sensor data. The speed damping signal is generated in response to extracting the symmetric oscillation information and the steering damping signal is generated in response to extracting the asymmetric oscillation information. A movement of the vehicle is modified using one or both of the speed damping signal or the steering damping signal.
