Seed Variety Selection System for Precision Planting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current precision farming methods face challenges in quickly transitioning between different seed types during planting operations, leading to blending of seed types in the field, which affects the effectiveness and efficiency of crop input applications.
Innovation Solution
A seed variety selection system that includes a planter with row units equipped with auxiliary hoppers and seed transfer actuators, allowing for the selective supply of seeds to a seed meter, enabling rapid switching between seed types by using seed tenders and fill level sensors to manage seed flow and minimize blending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If seed types are varied throughout a field during planting operations, then precision farming effectiveness is improved, but seed blending between different input types occurs leading to reduced application accuracy
Solution Approach 1:
The system divides the seed supply system into separate bulk hoppers for different seed varieties, with each hopper independently controlled. This segmentation allows different seed types to be stored separately and delivered to specific row units without mixing, enabling precision farming while maintaining application accuracy.
Solution Approach 2:
The system pre-fills bulk hoppers with different seed varieties before planting operations begin. This preliminary action ensures that the correct seed types are already in position and ready for immediate delivery to the appropriate row units, preventing blending during the planting process.
2Adaptability or versatility
If seed transfer mechanisms are used to switch between input types, then seed type variation is enabled, but blending of seed types occurs at the metering units
Solution Approach 1:
The system uses separate bulk hoppers for different seed varieties, each with its own dedicated feed path to the seed meter. This segmentation eliminates the blending problem that would occur with a single hopper system by ensuring that only one seed type is fed to the meter at any given time.
Solution Approach 2:
The system introduces bulk hoppers as intermediary storage containers between the seed supply and the metering units. These bulk hoppers act as buffers that allow for clean transitions between different seed types without direct mixing at the meter, preventing seed blending.
3Speed
If traditional planting systems are used, then system simplicity is maintained, but rapid transition between seed types is not achieved
Solution Approach 1:
The system uses a universal seed meter that can receive seeds from multiple bulk hoppers, allowing it to plant different seed varieties through the same metering mechanism. This multi-functionality enables rapid seed type transitions without requiring multiple dedicated meters, balancing speed with manageable complexity.
Solution Approach 2:
The system employs dynamic control mechanisms that allow the seed meter to switch between different bulk hoppers based on real-time planting requirements. This dynamic capability enables rapid adaptation to different seed types while maintaining a relatively simple overall system structure.

AI summary
Systems, methods, and apparatus for selection of crop-input varieties. Multiple varieties of seeds may be planted with a row unit seed hopper having a plurality of compartments for receiving seed, each compartment having a seed passage through which seeds pass under gravity. A seed transfer actuator is disposed within or below the row unit seed hopper and is in communication with each of the seed passages and is configured to selectively open the seed passage of one of the plurality of compartments to permit the seeds therein to pass into the seed pool of a seed meter while closing the seed passage of other of the plurality of compartments to prevent the seeds from the other plurality of compartments passing into the seed pool of the seed meter.
