Automated Sample Transfer for Reinspection Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sample inspection automation systems are inefficient and labor-intensive when handling reinspection or additional inspection requests, as samples need to be manually loaded and unloaded from storage to analysis units, leading to delays and increased technician burden.
Innovation Solution
A sample inspection automation system with a storage unit that allows bidirectional transfer of samples and automatic reinspection capabilities, using a communication tool to manage sample requests and storage, reducing unnecessary storage and retrieval by directly transferring samples to analysis units upon request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If samples are stored in a storage unit after initial analysis, then sample storage capacity is improved, but reinspection efficiency deteriorates due to manual retrieval and reloading requirements
Solution Approach 1:
The system divides samples into different storage categories (storage unit for completed samples and buffer mechanism for potential reinspection samples), allowing automated retrieval based on reinspection requests without manual intervention in the entire storage system
Solution Approach 2:
A buffer mechanism is introduced as an intermediary between the storage unit and analysis unit. This buffer automatically holds samples that may need reinspection, eliminating the need for manual retrieval from the main storage unit while maintaining storage capacity
2Device complexity
If a common tray is used for both sample loading and storage, then device complexity is reduced, but automation capability deteriorates due to manual sample placement requirements
Solution Approach 1:
The system separates the loading unit and storage unit into distinct functional zones with dedicated holders, enabling automated sample transfer mechanisms to operate without manual intervention while maintaining manageable structural complexity through modular design
Solution Approach 2:
The automated sample transfer mechanism enables the system to service itself by automatically moving samples from the loading unit to the storage unit and retrieving them for reinspection without requiring manual sample placement or retrieval
3Extent of automation
If samples are transferred through a buffer mechanism for automatic reinspection, then reinspection automation is improved, but sample transfer time increases due to buffer standby requirements
Solution Approach 1:
Samples are placed in the buffer mechanism in advance during the initial transfer from the loading unit, so that when a reinspection request is made, the sample is already positioned and ready for immediate automated retrieval and reanalysis, minimizing delay

AI summary
The invention provides a sample inspection automation system capable of easily, reliably, and efficiently responding to requests for reinspection or addition of inspection items. The sample inspection automation system includes a storage unit having a sample replacing mechanism for transferring a sample from a tray to a sample transfer line. When the system receives sample retrieval information through the communication between an operating unit and a laboratory information system (LIS), or a host system of the sample inspection automation system, the sample is transferred to the appropriate sample treatment unit through the transfer line. Thus, when a request for reinspection or addition inspection is issued, the sample inspection automation system can efficiently respond to it.
