Solution Overview
Problem
Existing seed vigor detection devices lack full automation in the process of seed placement, detection, and screening, resulting in slow detection speeds and resource inefficiencies.
Innovation Solution
An automatic detection device for seed vigor that arranges seeds in a matrix on a seeding disc, uses a hyperspectral lens for scanning, and employs a multi-axis mechanical arm to accurately remove non-vigorous seeds with a seed sucker, integrating a seeding mechanism and seed screening system for automated seed placement, detection, and screening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional physiological and biochemical methods are used for seed vigor detection, then reliable identification results are obtained, but the detection cycle is long and cost is high
Solution Approach 1:
The patent replaces traditional mechanical and chemical detection methods with hyperspectral imaging technology. The hyperspectral camera captures spectral information from seeds, and the processing unit analyzes this data to determine seed vigor, eliminating the need for lengthy physiological and biochemical tests while maintaining reliability.
Solution Approach 2:
The patent transforms the detection approach by measuring spectral parameters (reflectance across multiple wavelengths) instead of waiting for physiological responses. By analyzing spectral characteristics in the visible and near-infrared ranges, the system quickly identifies seed vigor without requiring the extended timeframes of traditional germination or biochemical assays.
2Productivity
If spectral imaging technology is used for seed vigor detection, then detection efficiency is improved and sample damage is reduced, but the entire process does not realize full automation and detection speed is slow
Solution Approach 1:
The patent combines the hyperspectral imaging system with an automated seed placement mechanism and sorting system. The seed placement mechanism positions seeds on a rotating disc in matrix format, the hyperspectral camera captures images, and the processing unit automatically analyzes the data and controls the sorting mechanism to separate vigorous from non-vigorous seeds, achieving full automation.
Solution Approach 2:
The system is designed to automatically perform all operations without manual intervention. The seed placement mechanism self-positions seeds, the hyperspectral camera self-captures images, the processing unit self-analyzes spectral data, and the sorting mechanism self-sorts seeds based on vigor assessment, creating a self-service automated detection and sorting system.
3Ease of operation
If manual seed placement and screening is performed, then flexibility is maintained, but manpower resources are consumed and detection speed is slow
Solution Approach 1:
The patent replaces manual seed placement and screening operations with automated mechanical systems. The seed placement mechanism uses vibration and airflow to position seeds automatically, while the sorting mechanism uses airflow to remove non-vigorous seeds, eliminating the need for manual labor and significantly increasing detection speed.
Solution Approach 2:
The patent employs pneumatic systems for both seed placement and sorting. Airflow is used to transport seeds to the placement mechanism and later to suction and remove non-vigorous seeds during sorting, providing automated, high-speed operation without manual intervention while maintaining operational flexibility through controllable airflow parameters.
