Optical Seed Detection for Selective Fertilizer Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural systems apply materials to fields in a continuous manner, leading to wastage as they often apply substances between seeds or plants, reducing productivity and efficiency, especially during high-rate fertilizer applications.
Innovation Solution
An optical seed detector identifies seed locations, and a material application control system dispenses materials based on seed positions, actuating valves or nozzles to apply materials precisely at desired locations, varying application rates according to seed proximity and other planting characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If material is applied in a substantially continuous way, then the application process is simple and continuous, but material wastage increases as substances are applied between seeds or plants
Solution Approach 1:
The continuous material application is segmented into discrete applications at specific seed locations. The system divides the field into individual seed zones and applies material only where needed, transforming a continuous process into a segmented, location-specific process that reduces material wastage between seeds
Solution Approach 2:
The system performs preliminary detection of seed locations using optical sensors before material application. By identifying seed positions in advance and planning material placement accordingly, the system ensures that material is applied only where seeds are present, preventing wasteful application in seed-less areas
2Manufacturing precision
If optical seed detection and selective material application systems are implemented, then material application precision is improved, but device complexity increases
Solution Approach 1:
The system merges multiple functions into integrated row units: optical seed detection, seed location processing, and controlled material application are combined in a unified system. This integration allows the components to work together seamlessly, achieving high precision material placement while managing overall system complexity through functional consolidation
Solution Approach 2:
The system uses real-time optical detection of seed locations as feedback to control material application. The detected seed positions are fed back to the control system, which adjusts material dispensing accordingly, creating a closed-loop system that achieves high precision while managing complexity through automated feedback control
3Productivity
If material is applied at high rates, then productivity is improved, but material wastage increases due to application between seeds
Solution Approach 1:
The system applies material at high rates locally at seed locations rather than uniformly across the entire field. By concentrating material application precisely where seeds are present and adjusting rates based on local seed density and requirements, the system achieves high productivity at target locations while eliminating wasteful application in seed-less areas
