Solution Overview
Problem
Current agricultural planting systems require manual and cumbersome adjustments to set the optimal seed depth, which often results in sub-optimal planting conditions due to changing environmental and soil characteristics.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual adjustment of gauge wheel position is used, then device complexity is reduced, but productivity and planting precision deteriorate due to time-consuming adjustments and sub-optimal depth settings
Solution Approach 1:
The patent replaces manual mechanical adjustment of the gauge wheel with an automated actuator system controlled by a processor. The actuator automatically adjusts the gauge wheel position based on signals from the control system, eliminating the need for manual intervention and improving planting speed while maintaining precision through automated control mechanisms.
Solution Approach 2:
The control system automatically adjusts planting depth without requiring operator intervention. The processor receives field data, determines optimal depth settings, and controls the actuator to make adjustments autonomously, allowing the system to serve itself rather than requiring manual reconfiguration during planting operations.
2Adaptability or versatility
If fixed downforce assembly is used, then device complexity is reduced, but adaptability to varying soil conditions deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of downforce through an actuator system that can modify the force applied to the row unit in real-time. This allows the downforce assembly to adapt to varying soil conditions, topography, and planting depth requirements, transforming a static system into a dynamic one that responds to field conditions as they change during planting operations.
Solution Approach 2:
The control system uses feedback from field data, including soil characteristics and topography information, to automatically adjust downforce settings. The processor receives data about field conditions and modifies the actuator output accordingly, creating a closed-loop control system that continuously adapts to varying environmental conditions without manual intervention.
3Manufacturing precision
If manual gauge wheel adjustment is used, then ease of operation is improved, but manufacturing precision and planting depth accuracy deteriorate
Solution Approach 1:
The patent replaces manual mechanical adjustment mechanisms with an automated actuator system controlled by electronic signals. This substitution eliminates the need for operators to physically adjust gauge wheel positions, thereby maintaining high planting depth precision through automated control while reducing the operational complexity for the user.
Solution Approach 2:
The actuator serves as an intermediary between the control system and the gauge wheel assembly. It translates electronic control signals into mechanical movement, enabling precise depth control without direct manual manipulation. The actuator mediates the interaction between the operator (through automated control) and the planting mechanism, maintaining precision while simplifying operation.

AI summary
An agricultural planter row unit has a gauge wheel supported by a gauge wheel arm, to control planting depth. An actuator drives movement of a mechanical stop that bears against a gauge wheel support arm to position the gauge wheel support arm to obtain a desired planting depth. A seed depth control system receives seed depth values generated based on field topography and automatically controls actuation of the seed depth actuator.
