Sample Rack Distribution Layout for Compact Multi-Module Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analysis systems face challenges in reducing system size and improving user accessibility due to the need for extended conveying lines and limited accessibility when multiple analysis modules are connected, particularly in module-type configurations.
Innovation Solution
The system employs a rotatable standby disk with non-parallel conveying and dispensing lines, allowing for a compact layout where all modules can be accessed from the same plane, and includes a sample rack distribution module with interposed conveying and dispensing units to enhance efficiency and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple analysis modules are connected in a module-type system with a common sample rack distribution module, then the system can perform multiple measurement methods, but the conveying line must be extended and the system size increases
Solution Approach 1:
The patent transitions from a linear arrangement of analysis modules to a radial arrangement around a central rotor-type sample rack distribution module. This dimensional change allows multiple analysis modules to be positioned in different directions (angular dimension) rather than extending in a single line, thereby reducing the overall footprint while maintaining the ability to perform multiple measurement methods through the same sample rack distribution mechanism
2Area of stationary object
If analysis modules are arranged in rotational symmetry around a central sample rack distribution module, then the system size is reduced, but user accessibility for maintenance and reagent replacement is limited
Solution Approach 1:
The patent introduces asymmetric elements into the otherwise radially symmetric arrangement. Specifically, the reagent disks are positioned at asymmetric locations relative to the radial symmetry, and the cover design allows asymmetric access. This enables users to access reagent disks and perform maintenance on one side of the system without needing to navigate around the entire circular arrangement, thus improving accessibility while maintaining the compact radial layout
3Adaptability or versatility
If the conveying line is extended to reach analysis modules arranged in the same direction, then all modules can be connected, but the conveying distance increases and efficiency decreases
Solution Approach 1:
The patent uses the angular dimension provided by the rotor-type distribution module to connect multiple analysis modules. Instead of extending the conveying line linearly in one direction, the system distributes sample racks radially to multiple modules positioned at different angles. This reduces the conveying distance for each module while maintaining connectivity to all modules through the central rotation mechanism

AI summary
Provided is an automatic analysis system in which a conveying line 104 and a plurality of dispensation lines 209, 309 are disposed not to be parallel, and a device layout of analysis modules 200, 300 disposed with a specimen rack distribution module 100 therebetween is line-symmetric with respect to a straight line 100A passing through the rotation center of a standby disc 106. Accordingly, even when the automatic analysis system has a configuration for providing specimens from a common specimen rack distribution module to a plurality of analysis modules, the conveyance efficiency of a specimen rack is raised and user accessibility is good.
