Solution Overview
Problem
Existing combine harvesters face inefficiencies due to operator-dependent adjustments of operating parameters, which can lead to sub-optimal performance under varying harvest conditions, such as moisture levels and crop types, requiring complex and often incomplete adjustments.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual adjustment of operating parameters is used, then operator control and flexibility are maintained, but harvesting efficiency and adaptability to changing conditions deteriorate
Solution Approach 1:
The system enables automatic self-adjustment of operating parameters through the controller receiving signals from sensors and autonomously modifying feed roller speed, working height, and feed finger positions without requiring continuous manual intervention, thereby maintaining harvesting efficiency while reducing operator burden
Solution Approach 2:
The system implements closed-loop feedback control where sensors continuously monitor harvesting conditions (moisture content, crop type, throughput) and transmit signals to the controller, which automatically adjusts operating parameters based on real-time conditions, resolving the contradiction between automatic optimization and operator control
2Adaptability or versatility
If operating parameters are adjusted to adapt to changing harvest conditions, then harvesting performance improves, but the complexity and time required for adjustments increases
Solution Approach 1:
The system dynamically adjusts operating parameters in real-time based on changing harvest conditions through automatic control, eliminating the need for complex manual reconfiguration and allowing the combine harvester to adapt to different crop types, moisture levels, and throughput requirements without increasing operational complexity
Solution Approach 2:
The system replaces manual mechanical adjustment operations with automated electronic control, where the controller receives electronic signals from sensors and automatically modifies operating parameters through electronic actuators, thereby improving adaptability while reducing the complexity and time of adjustments
3Adaptability or versatility
If operating parameters are adjusted to adapt to changing harvest conditions, then harvesting performance improves, but the time and effort required for adjustments increases
Solution Approach 1:
The system performs automatic self-adjustment of operating parameters through the controller receiving signals from sensors and autonomously modifying feed roller speed, working height, and feed finger positions without requiring continuous manual intervention, thereby maintaining harvesting efficiency while reducing operator burden
Solution Approach 2:
The system enables continuous automatic adjustment of operating parameters throughout the harvesting process without interrupting workflow, allowing the combine harvester to continuously adapt to changing conditions (moisture content, crop type, throughput) while eliminating the time loss associated with manual stopping and reconfiguration
