Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cool boxes for automatic analyzers face a decrease in sealability due to ventilation ports, which allows reagent components to evaporate and deteriorate, and inefficient removal of analysis inhibitors, affecting analyte analysis accuracy.
Innovation Solution
Incorporating an air circulator with an intake and exhaust system that includes an agent retaining portion for an analysis inhibitor removing agent, positioned in the intake and exhaust portions, to circulate air and remove components that inhibit analyte analysis, while maintaining sealability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If ventilation ports are formed in the peripheral wall of the cool box casing to exhaust evaporating reagent components, then the removal of analysis inhibitors is improved, but the sealability of the reagent storage unit deteriorates
Solution Approach 1:
The harmful function of ventilation ports (exhausting evaporating reagent components) is extracted and transferred to a mobile blade member that can be selectively positioned. The blade member is removed from the sealed casing structure and operated independently within the sealed environment, allowing vapor removal without compromising the sealed barrier between interior and exterior environments.
Solution Approach 2:
The blade member acts as an intermediary element that mediates between the sealed storage environment and the need for vapor removal. It provides a controlled interface for vapor exhaust without creating permanent openings in the sealed casing, thus maintaining sealability while enabling harmful vapor removal.
2Productivity
If multiple ventilation ports are provided in the peripheral wall to efficiently exhaust reagent components, then the removal efficiency of analysis inhibitors is improved, but the sealability of the reagent storage unit further deteriorates
Solution Approach 1:
The static ventilation ports are replaced with a dynamic blade member that can rotate and change position. This dynamic element can be moved to different locations within the sealed space to optimize vapor removal efficiency without requiring multiple fixed openings in the sealed casing, thus maintaining sealability while improving productivity.
Solution Approach 2:
The blade member serves multiple functions: it acts as a vapor exhaust mechanism, a mixing element, and a controllable flow director. This multi-functional design replaces the need for multiple specialized ventilation ports, achieving efficient vapor removal through a single sealed component.
3Device complexity
If the filter is placed horizontally relative to the air flow direction, then the structure is simplified, but the removal efficiency of reagent components deteriorates as most evaporating components do not flow into the filter
Solution Approach 1:
The static horizontal filter placement is replaced with a dynamic blade member that can rotate to optimal positions for vapor interception. The blade member's rotational capability allows it to dynamically align with vapor flow patterns, maximizing removal efficiency without requiring complex fixed filtration structures.
Solution Approach 2:
The passive mechanical filter system is replaced with an active blade member system that uses rotational motion to actively intercept and direct vapors. This substitution transforms a static filtration approach into a dynamic mechanical intervention that adapts to vapor flow patterns, improving removal efficiency.

Function Achieved in This Case
This solution enhances the efficiency of removing analysis inhibitors and maintains the sealability of the cool box, ensuring accurate analyte analysis by effectively circulating and purging air within the cool box.
Implementation Method 1
The air circulator sucks air from the receiving space through the intake portion and exhausts the sucked air into the receiving space through the exhaust portion by rotation of the fan, whereby circulating the air inside the receiving space
Implementation Method 2
at least one agent retaining portion on which an inhibitor removing agent is set, the removing agent acting to remove components (herein may also be referred to as the analysis inhibitor) adversely affecting or inhibiting analysis of the analytes

AI summary
There is provided a cool box for use in an automatic analyzer. The cool box has a box body and an air circulator. The box body has a receiving space capable of accommodating therein receptacles for analytes or reagents. The circulator has an intake portion, a fan, and an exhaust portion and operates to circulate air in the receiving space by rotation of the fan. The circulator further includes an inhibitor removing agent retaining portion on which a pouch is set. The pouch contains an analysis inhibitor removing agent for removing components (analysis inhibitor) which adversely affect or inhibit analysis of the analytes.
