Reagent Retaining Portion Peeling Structure for Humidity Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional analyzing devices experience unreliable measurements due to reagent fluidization at high humidity, causing reagent to flow into the measuring chamber and reservoir before the liquid reaches the separating chamber, leading to varying measured values.
Innovation Solution
A peeling portion is connected to the outer edge of the reagent retaining portion, allowing the reagent to spread and shrink, forming a smaller, thicker dried state that prevents moisture absorption from reaching the interior, thus preventing fluidization under centrifugal force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the analyzing device is used at high humidity, then the reagent absorbs moisture and fluidizes, but this causes the reagent to flow into the measuring chamber and reservoir before the liquid reaches the separating chamber, reducing measurement reliability
Solution Approach 1:
The reagent retaining portion is designed with a specific local structure where the outer edge is connected to the peeling portion, creating a localized retention mechanism. This local quality difference allows the reagent to be held in a specific region during drying, preventing it from flowing to incorrect chambers while maintaining overall device functionality.
Solution Approach 2:
The reagent is dried in advance on the reagent retaining portion before the actual measurement process. This preliminary drying action converts the reagent from a fluid state to a solid state, preventing premature fluidization and flow during subsequent high-humidity storage or operation. The peeling portion structure facilitates this preliminary retention and drying action.
2Reliability
If the reagent is dried into a smaller size with certain thickness, then moisture absorption is prevented from reaching the interior, but this requires a specific drying process and structure
Solution Approach 1:
The reagent retaining portion utilizes a thin-film or shell-like structure that allows the reagent to be dried into a compact, thickened form. This structure provides sufficient retention capability while maintaining a simple overall design. The peeling portion connected to the outer edge creates a controlled drying environment that produces the desired thickened reagent layer without requiring complex additional components.

AI summary
A feature of an analyzing device is that a peeling portion (14) extending outward is partially connected to the outer edge of a reagent retaining portion (13) that is formed in a separating chamber (6) provided in a main unit case (2) and retains a reagent (8). With this configuration, when a droplet of the reagent (8) is dried and fixed on the reagent retaining portion (13), an external force applied to the droplet can be smaller than that on other portions. The dried reagent (8) starts shrinking from the position of the peeling portion 14. At the completion of drying, the reagent (8) can be smaller in size than the reagent retaining portion (13) in plan view and can be larger in thickness than the related art.
