Electrolyte Analyzer Reagent Partition Wall Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrolyte analyzing devices face contamination risks during reagent replacement, especially when different reagents come into contact with the suction nozzle, leading to incorrect measurement results and wastage of consumable reagents, particularly due to the high concentration of the reference electrode solution.
Innovation Solution
The device incorporates a reagent container setting unit with a partition wall between the dilute solution, internal standard solution, and reference electrode solution bottles, allowing for controlled reagent replacement even when the device is not powered on, preventing contamination by mechanically locking the suction nozzle until power is supplied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover with locking mechanism is provided on the reagent container setting unit to prevent misplacement, then reliability is improved, but device complexity increases
Solution Approach 1:
The reagent container setting unit is divided into separate compartments for different reagents (reference electrode solution, dilute solution, standard solution). Each compartment has its own cover that can be independently opened and closed, allowing selective access to specific reagents while maintaining isolation between them. This segmentation prevents cross-contamination without requiring a complex global locking mechanism.
Solution Approach 2:
The partition walls are pre-installed to create separate compartments before reagent containers are placed. This preliminary structural arrangement ensures that even if covers are opened during replacement operations, reagents cannot scatter or mix between compartments, providing passive protection against contamination.
2Ease of operation
If reagent replacement is allowed when device is not powered on, then ease of operation is improved, but reliability deteriorates due to contamination risk
Solution Approach 1:
The setting unit is segmented into separate compartments with individual covers for each reagent type. Users can open only the specific compartment needing replacement while other compartments remain sealed, allowing safe replacement operations even when the device is powered off without risking cross-contamination.
Solution Approach 2:
Partition walls act as intermediaries between different reagent compartments, physically preventing direct contact and mixing of reagents during replacement operations. This intermediary structure enables users to safely handle one reagent at a time without affecting others.

AI summary
Provided is an electrolyte analyzing device in which contamination caused by contacting different reagents with a suction nozzle is prevented when reagent replacement is performed by a user. The electrolyte analyzing device includes a reagent container setting unit 502 that sets a dilute solution bottle 101-1 which houses a dilute solution, an internal standard solution bottle 101-2 which houses an internal standard solution, and a reference electrode solution bottle 101-3 which houses a reference electrode solution. The reagent container setting unit includes a partition wall between the dilute solution bottle 101-1 and the internal standard solution bottle 101-2, and the reference electrode solution bottle 101-3 when the dilute solution bottle 101-1, the internal standard solution bottle 101-2, and the reference electrode solution bottle 101-3 are set.
