Solution Overview
Problem
Current seeding technologies face inefficiencies in seed sorting, particularly with fine seeds, due to overlapping seeds and complex structures, leading to reduced sorting accuracy and increased labor costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If seeds are vertically stacked in a seed box, then seed storage capacity is improved, but individual sorting efficiency deteriorates because seeds overlap each other
Solution Approach 1:
The seed box is divided into multiple seed receiving grooves that are spatially separated. Each groove receives seeds from a corresponding seed inserting groove on the rotating drum, ensuring that seeds are distributed individually across multiple locations rather than stacked vertically. This segmentation prevents overlap and enables individual sorting of seeds while maintaining storage capacity.
2Manufacturing precision
If a complex seed sorting structure is used, then seed sorting accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The rotating drum serves multiple functions: it stores seeds in its grooves, transports them to the transfer plate, and positions them for individual sorting into the seed box. The transfer plate also performs multiple functions by receiving seeds from the drum and distributing them to multiple seed receiving grooves. This multi-functionality reduces the need for additional separate components, simplifying the overall structure while maintaining high sorting accuracy.
Solution Approach 2:
The system uses the rotation of the drum and gravity-assisted movement of seeds through the transfer plate to achieve seed distribution automatically. The seeds move from the drum's inserting grooves to the transfer plate and then to the seed box grooves through controlled gravity flow, reducing the need for complex mechanical sorting mechanisms and lowering manufacturing costs.
3Manufacturing precision
If seeds are sown one by one manually, then individual seed placement accuracy is improved, but time consumption increases
Solution Approach 1:
The rotating drum performs periodic rotations, with each rotation cycle placing multiple seeds into the seed box simultaneously. The drum has multiple seed inserting grooves that are positioned at different angles, allowing seeds to be deposited into corresponding seed receiving grooves at different times during each rotation. This periodic action enables high-speed automated seed placement with accurate individual positioning, eliminating the time-consuming manual one-by-one sowing process while maintaining placement precision.

The smart seeder effectively prevents seed overlap, enhances individual sorting efficiency, and simplifies the structure to reduce costs while accurately sorting seeds of varying sizes, including fine seeds like lettuce.
Implementation Method 1
a vibration generating unit configured to generate vibrations on the transfer plate, to spread the supplied seeds such that the seeds do not overlap each other
Implementation Method 2
a rotating drum arranged to be adjacent to one end of the transfer plate to be rotated, and having a seed inserting groove formed on an outer peripheral surface thereof, the seeds inserted into the seed sorting groove of the transfer plate being moved and inserted into the seed inserting groove according to rotation
Implementation Method 3
a guide unit configured to guide, to a cell of a tray pot, the seeds which are inserted into the seed inserting groove of the rotating drum according to the rotation of the rotating drum and freely fall

AI summary
A smart seeder which significantly enhances efficiency in individual seed separation by enabling the seeds supplied onto a transfer plate to be spread more easily so that the seeds do not overlap, and consequently by enabling the seeds to be separated individually. Furthermore, the smart seeder can not only significantly reduce production costs due to the simple structure thereof, but also significantly enhance seed separation efficiency by separating one or multiple seeds, which may comprise fine seeds, such as lettuce seeds, or the like, whether the seeds are small seeds or large seeds.
