Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing specimen inspection automation systems are limited by fixed types of specimen trays, which hinder flexible installation and usage, especially when handling different types of specimens, requiring hardware modifications and reducing operational efficiency.
Innovation Solution
A specimen-container loading or storing unit that allows for the free combination of multiple types of specimen trays, each with varying sizes and configurations, using RFID tags and readers for identification and management, enabling flexible selection and arrangement based on specific needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed type of specimen tray is used, then the system structure is simple, but the adaptability to different specimen handling requirements is poor
Solution Approach 1:
The patent implements a universal specimen tray system where a single tray design can accommodate multiple specimen container types and configurations. The tray includes adjustable support structures and universal mounting mechanisms that allow it to function with different specimen container sizes, shapes, and quantities without requiring hardware modifications to the tray itself, thus achieving multi-functionality while maintaining structural simplicity
Solution Approach 2:
The specimen tray incorporates dynamic and adjustable components such as movable support arms, adjustable positioning clips, and flexible mounting mechanisms. These dynamic elements allow the tray configuration to be adapted to different specimen handling requirements through simple adjustments rather than structural changes, enabling versatility while keeping the base system simple
2Adaptability or versatility
If hardware modifications are made to change specimen tray types, then the tray can be adapted to different needs, but the modification process is complex and time-consuming
Solution Approach 1:
The specimen tray is divided into modular segments and standardized components that can be independently adjusted or replaced. The tray structure includes separate functional modules such as support elements, positioning mechanisms, and mounting interfaces that can be reconfigured through simple assembly changes rather than complex manufacturing modifications, making it easy to adapt to different specimen handling needs
Solution Approach 2:
The invention enables adaptation of specimen trays through changing operational parameters such as tray position, support element configuration, and mounting orientation rather than modifying the physical structure. By adjusting these parameters within the existing hardware design, the system can accommodate different specimen container types and quantities without requiring manufacturing changes to the tray itself
3Productivity
If a dedicated specimen tray is prepared for each system, then the tray is optimized for specific use, but the system complexity increases due to multiple tray types
Solution Approach 1:
The patent implements a universal specimen tray design that can serve multiple systems and functions with a single tray type. The tray incorporates standardized interfaces and adjustable features that allow it to be used across different specimen handling systems and configurations, eliminating the need for multiple dedicated tray types while maintaining operational efficiency through optimized design features

AI summary
In the related art, a type of a specimen tray installed in a specimen-container loading or storing unit is fixed to about one or two types in advance. Further, when the number of types of the specimen trays is modified, a modification of hardware is required, thereby having a difficulty in flexibly installing and using the specimen trays with a random combination. Accordingly, in consideration of handling quantities of the specimen containers which are different from each other depending on every request and every specimen type, an optimized specimen tray cannot be selected, resulting in a hindrance in an efficient operation of the specimen-container loading or storing unit. In view of the above-mentioned problems, the invention is directed to a specimen-container loading or storing unit including: a plurality of types of specimen trays having a different size of a specimen tray that is provided with a plurality of specimen container installation parts for holding a specimen container; a specimen container transferring mechanism for transferring the specimen container between a conveyance line and the specimen tray; and a specimen tray installation part capable of installing the plurality of types of specimen trays.
