Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural work systems struggle to precisely correct the position and orientation of working tools during cornering and turning operations, leading to reduced work quality and potential crop damage due to imprecise detection of curved crop rows.
Innovation Solution
An agricultural work system equipped with an electronic control device that adjusts the position and orientation of working tools using a sliding frame based on a determined curved path, utilizing sensory detection devices such as gyroscopes, GPS sensors, and cameras to ensure precise alignment even when turning or cornering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If camera-based row guidance system is used to detect plant rows, then detection precision is improved when traveling straight ahead, but detection precision deteriorates when cornering or turning along curved crop rows
Solution Approach 1:
The patent replaces the camera-based optical detection system with a sensor-based detection system that uses gyroscopes and GPS to determine the vehicle's position, orientation, and movement path. This substitution allows the system to accurately detect curved paths and calculate the required correction values for working tools regardless of whether the vehicle is traveling straight or cornering, thereby resolving the contradiction between detection precision and adaptability to curved paths.
2Manufacturing precision
If sliding frame is used to correct position and orientation of working tools, then correction precision is improved when traveling straight ahead, but correction precision deteriorates during cornering and turning operations
Solution Approach 1:
The system performs preliminary detection of the vehicle's position, orientation, and movement path using sensors before the working tools reach positions that would require correction. The control device calculates correction values in advance based on the determined curved path, and the sliding frame is positioned accordingly before the working tools need adjustment. This preliminary action ensures that correction precision is maintained during cornering and turning operations, resolving the contradiction between correction precision and adaptability to driving maneuvers.
3Reliability
If camera-based row guidance system is used, then work quality is improved on linear plant rows, but work quality deteriorates on curved crop rows due to imprecise detection
Solution Approach 1:
The patent replaces the camera-based optical detection system with a sensor-based detection system that uses gyroscopes and GPS to determine the vehicle's position, orientation, and movement path. This substitution allows the system to accurately detect curved paths and calculate the required correction values for working tools regardless of whether the vehicle is traveling straight or cornering, thereby resolving the contradiction between work quality and detection precision on curved rows.
4Speed
If traditional row guidance correction is used, then correction speed is fast when traveling straight, but correction accuracy deteriorates during cornering operations
Solution Approach 1:
The system continuously receives feedback from sensors about the vehicle's position, orientation, and movement path, and the control device continuously calculates correction values based on the determined curved path. The sliding frame is adjusted in real-time based on this feedback, ensuring that correction accuracy is maintained during cornering and turning operations while maintaining fast correction speed through automated control.
