Agricultural Implement Weight Adjustment via Wheel Slip Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern agricultural machinery, particularly ploughs, face challenges with excessive wheel slip due to increasing size and weight, leading to reduced tillage efficiency and potential vehicle immobilization in the field.
Innovation Solution
A computer-implemented method and control unit for agricultural machinery that receives wheel-slip data and determines actuator-control signals to adjust the position and operation of ground engaging tools, such as changing working depth, width, and angle, to maintain optimal wheel slip levels, thereby improving traction and preventing vehicle immobilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the agricultural implement is made larger and heavier to increase tillage efficiency, then the tillage capacity and productivity are improved, but the wheel slip of the towing vehicle increases excessively
Solution Approach 1:
The patent applies dynamics by making the implement weight adjustable rather than fixed. The system dynamically adapts the implement weight based on real-time wheel slip detection, allowing the implement to transition between different weight states to optimize both productivity and prevent vehicle immobilization
Solution Approach 2:
The patent implements a feedback control system where wheel slip is continuously monitored and used to adjust implement weight. The control unit receives wheel slip data and automatically adjusts the implement weight to maintain optimal traction, creating a closed-loop system that prevents excessive wheel slip while maintaining high tillage efficiency
2Productivity
If the agricultural implement is made larger and heavier to increase tillage efficiency, then the tillage capacity is improved, but the fuel consumption increases
Solution Approach 1:
The system dynamically adjusts implement weight based on actual tillage conditions and wheel slip detection, allowing the implement to operate at optimal weight rather than constantly carrying maximum weight. This reduces unnecessary energy consumption while maintaining high tillage efficiency when needed
Solution Approach 2:
The patent changes the weight parameter of the implement dynamically based on operating conditions. By adjusting the implement weight parameter in response to wheel slip and tillage requirements, the system optimizes the balance between tillage efficiency and fuel economy
