Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In clinical testing, existing systems require operators to manually prepare and manage multiple reagent bottles of varying sizes and capacities, posing challenges, especially for less skilled operators handling nighttime or urgent tests, as they struggle to select the correct reagent combinations and settings for different facilities and test volumes.
Innovation Solution
A reagent cassette system with an integrated information recording medium, such as a barcode label or IC chip, that stores information about reagent bottle sizes, types, and suction positions, allowing the automatic analyzer to recognize and manage reagent bottles efficiently, enabling flexible selection and setup based on test requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple reagent bottles of varying sizes and capacities are manually prepared and managed, then the system can accommodate different facilities and test volumes, but the complexity of reagent management increases and less skilled operators struggle to select correct reagent combinations
Solution Approach 1:
The system divides reagent management into modular components: individual reagent bottles with unique identifiers, organized within reagent cassettes that are loaded into the analyzer. This segmentation allows flexible configuration for different test volumes while simplifying operator interaction to basic steps of inserting pre-configured cassettes.
Solution Approach 2:
The system uses information recording media (barcodes, RFID tags) on reagent bottles and cassettes that contain digital copies of reagent identification, capacity, and compatibility information. The analyzer reads these copies to automatically determine the correct reagent combinations, eliminating the need for operators to manually match physical reagent characteristics.
2Productivity
If reagent bottles with large capacity are used, then the system can handle high-volume testing, but the reagent cannot be completely used in the effective period after opening and is discarded
Solution Approach 1:
The system dynamically adapts reagent capacity selection to actual test volume requirements. The information recording media stores capacity metadata that the analyzer uses to automatically select appropriately-sized reagent bottles for the current workload, enabling high-volume facilities to use large bottles while low-volume facilities use smaller bottles, thereby minimizing waste in both scenarios.
Solution Approach 2:
The system changes the parameter of reagent bottle capacity selection based on test volume requirements. By storing multiple reagent bottle options with different capacities in the information recording media and automatically selecting the appropriate capacity parameter, the system matches reagent supply to actual demand, preventing both over-provisioning (waste) and under-provisioning (insufficient supply).
3Loss of information
If information regarding reagent content is specified for each reagent bottle, then the system can track individual reagents, but the operator is required to prepare two types of reagents for each measurement item and management becomes difficult
Solution Approach 1:
The system merges multiple individual reagent bottle information records into a single reagent cassette record. The information recording media on the cassette contains aggregated data about all reagents in the cassette, including their types, capacities, and relationships. This allows the analyzer to manage reagents at the cassette level rather than requiring operators to individually handle each bottle, significantly simplifying preparation while maintaining complete information tracking.
Solution Approach 2:
The reagent cassette acts as an intermediary between the analyzer and individual reagent bottles. The information recording media on the cassette stores and manages information about multiple reagents, serving as a mediator that translates individual bottle characteristics into a unified configuration that the analyzer can process automatically, eliminating the need for operators to manually manage each reagent's information.
4Ease of operation
If a combination of reagent bottles is decided beforehand and cannot be changed, then the system simplifies operator selection, but the system lacks flexibility for different test requirements
Solution Approach 1:
The system dynamically configures reagent combinations based on test requirements rather than using fixed pre-determined combinations. The information recording media stores multiple possible reagent configurations, and the analyzer automatically selects the appropriate combination based on the specific test being performed, maintaining both operational simplicity and adaptability.
Solution Approach 2:
The reagent cassette design with information recording media creates a universal platform that can accommodate multiple reagent types and configurations. The same physical cassette structure can hold different combinations of reagents depending on test requirements, and the information media encodes the specific configuration for that instance, enabling one system design to serve multiple functions across different test scenarios.

AI summary
A reagent cassette used in an automatic analyzer for a clinical examination room, which provides an analysis environment enabling an operator to select reagent bottles with proper capacities depending on the number of tests to be performed in each different type of facility and to properly set reagents with ease. In the automatic analyzer comprising a sample pipetting section, a reagent pipetting section, a reaction cuvette, etc., one component in a sample is analyzed by using the reagent cassette in which one or a plurality of reagent bottles containing two or more types of reagents are combined together. The reagent cassette is provided with a reagent identifier including information regarding the presence or absence of a reagent opening of the reagent bottle for each of a plurality of positions of the openings.
