Solution Overview
Problem
Current crop input applicators lack efficient monitoring and control systems to ensure precise application of crop inputs like seeds and fertilizers, leading to potential inefficiencies and inconsistencies in soil distribution.
Innovation Solution
A crop input monitoring system that includes a seed sensor, a crop input outlet, and a valve, which allows for real-time sensing of seeds and controlled deposition of crop inputs, ensuring precise placement and application rates through a controller and flow meter system integrated with a planter row unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If crop input applicators are used without monitoring and control systems, then the application process is simpler, but the precision and consistency of crop input distribution deteriorates
Solution Approach 1:
The patent implements a feedback control system where a sensor detects seed position and provides this information to a controller, which then adjusts the liquid applicator to maintain proper spacing. This closed-loop feedback mechanism ensures precise crop input distribution while automatically compensating for variations in seed placement
Solution Approach 2:
The patent replaces manual mechanical control with an automated electronic control system. The controller electronically actuates the liquid applicator based on sensor input, substituting mechanical adjustment mechanisms with electronic control to achieve more precise and consistent operation
2Manufacturing precision
If manual crop input application is used, then the system is easier to operate, but the application rate consistency and placement accuracy deteriorates
Solution Approach 1:
The system performs self-correction through automatic control. The sensor continuously monitors seed position and the controller automatically adjusts liquid application without requiring manual intervention. This self-service capability maintains high placement accuracy while simplifying operator tasks to basic system oversight
3Productivity
If crop input application is not synchronized with seed placement, then the application process is faster, but the agronomic efficiency and waste reduction deteriorates
Solution Approach 1:
The system performs preliminary detection of seed position before liquid application occurs. The sensor detects seed placement in advance, allowing the controller to pre-position the liquid applicator and synchronize delivery timing. This preliminary action ensures precise synchronization without significant time loss
Solution Approach 2:
The monitoring and control system operates continuously during the planting process, constantly detecting seed position and adjusting liquid application. This continuous operation maintains synchronization without interrupting the planting workflow, ensuring agronomic efficiency while minimizing time loss through seamless integration

AI summary
In one aspect, a crop input applicator is provided. In one aspect, the applicator comprises a valve (e.g., voice coil valve) disposed to deposit liquid on or near a seed furrow and/or on or near a seed. In one aspect, the applicator includes one or more seed sensors disposed to detect passage of seeds.
