Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for placing specific types or varieties of seeds on seed tape are labor-intensive, time-consuming, and prone to errors, especially in research operations where genetic traits are being tested.
Innovation Solution
A system comprising a seed extraction assembly with a gantry and an accumulator with helically arranged pockets, allowing for the automated selection and placement of seeds onto a seed tape, utilizing a pick head to remove seeds from containers and deposit them into the accumulator, which then rotates to position them accurately on the tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual labor is used to place specific types or varieties of seeds onto seed tape, then seed selection and placement can be performed, but the process becomes labor-intensive, time-consuming, and prone to errors
Solution Approach 1:
The system divides the seed tape into discrete segments corresponding to individual seed positions. The accumulator is segmented into multiple pockets, each capable of holding a single seed. This segmentation allows for precise individual seed placement while maintaining an organized, automated process that reduces errors and labor intensity.
Solution Approach 2:
The accumulator serves as an intermediary device between the seed source and the seed tape. It temporarily stores selected seeds in individual pockets and presents them one at a time to the seed tape. This intermediary mechanism enables automated, precise seed placement without requiring complex real-time selection systems, thus reducing overall system complexity while maintaining high automation.
2Manufacturing precision
If uniform spacing of seeds is used on the tape, then plant spacing is uniform and thinning is reduced, but the ability to place specific varieties or track individual seeds is limited
Solution Approach 1:
The system applies local quality by allowing different seed varieties to be placed at specific, predetermined locations on the seed tape. Each pocket in the accumulator can be assigned to hold a specific seed variety, enabling precise control over which seed goes to which location. This maintains uniform spacing while adding the versatility to place specific varieties where needed for research or trial planting applications.
3Reliability
If seeds are placed manually for research operations to test genetic traits, then seed selection is possible, but the process is time-consuming and costly
Solution Approach 1:
The system performs preliminary action by pre-organizing seeds into the accumulator pockets before placement on the seed tape. Seeds are selected and stored in the accumulator in advance, allowing for rapid, accurate placement. This preliminary organization eliminates the need for time-consuming manual selection during the placement process, significantly reducing the time required while maintaining high accuracy for research operations.
