Immunoassay Analyzer Reaction Unit Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional immunoassay analyzers face limitations in flexibility due to the combined design of incubation, detection, and B/F functions, leading to restricted rotation, complex structure, high cost, and unstable temperature control, which affects test accuracy and efficiency.
Innovation Solution
The separate arrangement of reaction units for incubation and B/F functions prevents mutual influence, allowing for more flexible testing and a simpler system structure, with the reaction unit performing both incubations and detection in the same unit to improve efficiency and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If incubation, detection, and B/F functions are combined in the same disk, then the structure is integrated, but the disk rotation is restricted and the structure becomes complex
Solution Approach 1:
The patent divides the analyzer into separate functional modules: a reaction unit for incubation and detection, and a separate B/F unit for bound-free separation. This segmentation allows the reaction disk to rotate freely without being constrained by B/F mechanisms, resolving the contradiction between structural integration and rotational flexibility.
2Volume of stationary object
If incubation, detection, and B/F are performed in the same disk, then the system is compact, but the temperature control becomes unstable due to B/F operations
Solution Approach 1:
By separating the B/F unit from the reaction unit, the patent eliminates temperature fluctuations caused by B/F operations during incubation. The reaction unit maintains stable temperature for incubation while the B/F unit operates independently, resolving the contradiction between system compactness and temperature stability.
3Adaptability or versatility
If multiple B/F equipments are added to support two step one B/F protocol, then the testing capability is enhanced, but the cost increases
Solution Approach 1:
The patent designs a universal B/F unit that can handle multiple test protocols including two-step one B/F protocol. The reaction unit and B/F unit are designed to work together flexibly, allowing a single B/F unit to serve multiple functions rather than requiring separate B/F equipments for different protocols, thus reducing cost while maintaining versatility.
4Reliability
If separate structural units are used for incubation, B/F, and detection, then the functions are independent, but the system structure becomes complex and cost increases
Solution Approach 1:
The patent implements a balanced segmentation approach where the reaction unit (combining incubation and detection) is separated from the B/F unit. This provides functional independence between incubation and B/F operations while avoiding the excessive complexity of completely separate units for all functions, thus resolving the contradiction between reliability and structural complexity.
