Solution Overview
Problem
Current methods for operating agricultural loading wagons are limited in achieving optimal loading efficiency, as they lack effective means to determine and adjust the mass and distribution of crops during the loading process, leading to suboptimal filling and potential overload or uneven distribution.
Innovation Solution

Engineering Contradiction Analysis
1Productivity
If traditional loading methods are used without mass and distribution monitoring, then the loading process is simpler and requires fewer sensors, but the loading efficiency is suboptimal and uneven distribution occurs
Solution Approach 1:
The loading space is divided into multiple measurement zones with distributed sensors along the longitudinal direction. Each sensor monitors a specific segment, allowing localized mass and distribution assessment. This segmentation enables precise control of crop distribution while maintaining manageable system complexity through modular sensor placement.
Solution Approach 2:
The system continuously monitors mass and center of gravity position using distributed sensors, then feeds this information back to the control device. The control device adjusts loading parameters in real-time based on this feedback, creating a closed-loop control system that optimizes loading efficiency while preventing overload and ensuring uniform distribution.
2Measurement precision
If manual monitoring and adjustment of loading parameters is performed, then the system is simpler to implement, but the precision of mass and distribution control is insufficient
Solution Approach 1:
Manual monitoring and adjustment mechanisms are replaced with an automated sensor-based measurement system and electronic control device. The sensors continuously measure mass and center of gravity position with high precision, and the control device automatically adjusts loading parameters without human intervention, achieving both high measurement precision and automation.
Solution Approach 2:
The loading system performs self-monitoring and self-adjustment through the integrated sensor network and control device. The system automatically detects mass distribution, calculates center of gravity position, and adjusts loading parameters without requiring external manual intervention, enabling the system to serve itself in optimizing the loading process.
3Reliability
If the wagon is loaded without real-time mass monitoring, then the loading process is faster and requires less data processing, but overload conditions cannot be prevented
Solution Approach 1:
The system performs preliminary mass monitoring during the loading process using distributed sensors that continuously measure mass accumulation. By detecting mass and center of gravity position in real-time before overload occurs, the system can prevent overload conditions proactively, ensuring reliability without requiring extensive post-loading data processing.
