Sample Measurement Reagent Container Pressing for Airtight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample measuring apparatuses face issues with insufficient airtightness of reagent containers due to incomplete closure of the lid portion, leading to evaporation and denaturing of reagents.
Innovation Solution
A sample measuring apparatus is designed with a pressing unit that ensures complete closure of the reagent container lid by pressing it down onto the opening, thereby maintaining excellent airtightness during opening and closing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid portion is closed only by pressing it horizontally by the projecting portion, then the opening/closing operation is simple, but the airtightness is insufficient and the lid may not be completely closed
Solution Approach 1:
The closing action is divided into two distinct phases: first, the projecting portion performs the opening/closing operation by pivoting the lid horizontally; second, the pressing portion independently applies vertical pressing force to ensure complete closure and airtightness. This segmentation allows each component to specialize in one function, resolving the contradiction between operational simplicity and reliable sealing.
Solution Approach 2:
The solution adds a vertical dimension to the closing mechanism. While the projecting portion operates horizontally to pivot the lid open and closed, the pressing portion applies force in the vertical direction to press the lid completely against the container opening. This multi-dimensional approach ensures both ease of operation and excellent airtightness.
2Device complexity
If the lid portion is not completely closed, then the opening/closing mechanism is simpler, but evaporation and denaturing of reagent occur
Solution Approach 1:
The pressing portion is designed to preemptively compensate for any potential gaps or incomplete closures. By continuously applying vertical pressing force after the lid is pivoted closed, the system ensures that the lid is always completely sealed against the container opening, preventing evaporation and denaturing before they can occur.
Solution Approach 2:
The pressing portion automatically activates after the lid is closed by the projecting portion. The system self-regulates to ensure complete closure without requiring additional manual intervention or complex control mechanisms, maintaining simplicity while preventing harmful effects.

AI summary
A sample measuring apparatus, A reagent container, and a method of measuring a sample are provided. The sample measuring apparatus includes: a container holding unit that holds a reagent container comprising an openable/closable lid portion that covers an opening of the reagent container; a reagent dispensing unit that aspirates a reagent in the reagent container with the lid portion being in an opened state and dispenses the aspirated reagent into a reaction container; a pressing unit that seals the opening, by pressing toward the opening the lid portion laid over the opening; and a measuring unit that measures components contained in a measurement specimen prepared from a sample and the reagent dispensed in the reaction container.
