Solution Overview
Problem
Farmers and agronomists face challenges in maximizing yield and profit by optimizing seed population and nitrogen application rates in crop cultivation, as existing systems lack the ability to vary crop input application rates effectively across fields.
Innovation Solution
A system comprising a planter with variable seed population control, driven by a processor-based monitor that uses GPS data to adjust seed deposition rates according to prescription maps, allowing for precise application rates based on location, and includes sensors to record and analyze planting data for improved yield optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If variable seed population control is implemented using GPS and prescription maps, then manufacturing precision of seed deposition is improved, but device complexity increases
Solution Approach 1:
The planter system integrates multiple functions including GPS reception, prescription map processing, variable rate seed deposition control, and data recording into a single unified system. The monitor serves as a central control unit that coordinates all these functions, allowing one device to perform what would otherwise require multiple separate systems.
Solution Approach 2:
The patent introduces a monitor as an intermediary device that receives GPS data, processes prescription maps, and controls the seed deposition mechanism. This intermediary layer simplifies the overall system architecture by centralizing control logic and providing a interface between the GPS system and the mechanical planting components.
2Productivity
If crop input application rates are varied across fields, then productivity is improved, but ease of operation deteriorates
Solution Approach 1:
The system requires prescription maps to be prepared in advance, with specific seed population rates designated for different field zones. This preliminary preparation of application rate data allows the planter to automatically vary seed deposition without requiring real-time operator decisions, simplifying operation during actual planting.
Solution Approach 2:
The monitor records actual seed deposition data and GPS location information, providing feedback on the variable rate application process. This feedback mechanism allows operators to verify that the system is functioning correctly and provides data for future optimization, making the complex operation more controllable and understandable.
3Manufacturing precision
If precise location-based seed deposition is achieved using GPS, then manufacturing precision is improved, but loss of time increases
Solution Approach 1:
The system uses GPS to create a digital copy of the field layout and prescription map data, which is then processed by the monitor to control seed deposition. This digital copying and processing approach allows for precise location-based control without requiring physical measurement or manual marking of the field, significantly reducing preparation time.
