Automated Analyzer Priority Dispensing for Urgent Specimens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated analyzers process specimens in a fixed order, preventing higher-priority specimens from being processed rapidly.
Innovation Solution
An automated analyzer with a management unit that determines the dispensing order of pre-treated specimens based on priority, allowing higher-priority specimens to be dispensed into reaction containers before lower-priority ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If specimens are processed in a fixed input order, then the processing sequence is simple and stable, but higher-priority specimens cannot be processed rapidly
Solution Approach 1:
The system performs preliminary classification of specimens into priority levels upon input, and pre-arranges their storage positions in the turntable based on priority. When a high-priority specimen becomes ready for processing, it is already positioned for rapid dispensing without requiring complex real-time reordering during the processing cycle.
Solution Approach 2:
The specimen dispensing order is made dynamic rather than fixed. The control unit dynamically adjusts the dispensing sequence based on real-time priority information, allowing high-priority specimens to be inserted into the processing queue ahead of lower-priority ones while maintaining overall system coordination.
2Productivity
If the dispensing order follows the input sequence, then the control logic is simple, but the processing efficiency for urgent specimens is reduced
Solution Approach 1:
The system incorporates feedback mechanisms where the control unit continuously monitors specimen priority status and processing readiness. Based on this feedback, it automatically adjusts the dispensing sequence to prioritize urgent specimens while maintaining simple operational control through automated decision-making.
Solution Approach 2:
The system changes the ordering parameter from strict input-sequence-based to priority-based ordering. By introducing priority level as a key parameter in the dispensing decision logic, the system achieves both improved throughput for high-priority specimens and maintained control simplicity through clear priority-based rules.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid processing of higher-priority specimens by rearranging the dispensing order to prioritize them over lower-priority specimens.
Implementation Method 1
a first dispensing probe that dispenses a specimen and pre-treatment liquid into one of the pre-treatment containers and generates a pre-treated specimen
Implementation Method 2
a second dispensing probe that sucks the pre-treated specimen from one of the pre-treatment containers and dispenses the sucked pre-treated specimen into one of the reaction containers

AI summary
An automated analyzer includes: a first turntable that holds a plurality of pre-treatment containers; a first dispensing probe that dispenses a specimen and pre-treatment liquid into one of the pre-treatment containers and generates a pre-treated specimen; a second turntable that holds a plurality of reaction containers; a second dispensing probe that sucks the pre-treated specimen from one of the pre-treatment containers and dispenses the pre-treated specimen into one of the reaction containers; a measurement unit that measures the pre-treated specimen stored in one of the reaction containers; a management unit that determines an order in which the pre-treated specimen stored in one of the pre-treatment containers is dispensed by the second dispensing probe, based on priority of the pre-treated specimen, when the pre-treated specimen becomes dispensable into one of the reaction containers; and a control unit that causes the second dispensing probe to dispense the pre-treated specimen in accordance with the order determined by the management unit.
