Electrolyte Analyzer Electrode Assembly for Leak-Safe Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrolyte analyzers impose a significant burden on users during electrode replacement due to the need for separate handling and potential leakage when the timing of replacing ISE and reference electrodes differs, necessitating cleaning of both even if only one is replaced.
Innovation Solution
The electrolyte analyzer incorporates a housing with a pressing unit and switching units for each electrode group, allowing simultaneous securement or release of ISE and reference electrodes, reducing the need for separate handling and minimizing leakage during replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate handling of ISE electrodes and reference electrodes is used, then each electrode can be replaced independently, but leakage occurs when timing differs and cleaning burden increases
Solution Approach 1:
The patent combines the ISE electrode and reference electrode into a single integrated electrode assembly that is replaced as one unit. This merging eliminates the problem of differential replacement timing and ensures both electrodes are either both secured or both released, preventing liquid leakage while simplifying the replacement operation to a single action.
Solution Approach 2:
The electrode assembly is segmented into replaceable modules where the ISE electrode and reference electrode can be independently replaced together as a unit. This segmentation allows the assembly to be designed with modular components that maintain secure contact during operation but can be easily replaced as a complete unit, preventing leakage issues.
2Adaptability or versatility
If separate handling of electrodes is used, then replacement flexibility is maintained, but cleaning burden on user increases
Solution Approach 1:
By merging the ISE electrode and reference electrode into a single replaceable assembly, the patent maintains replacement flexibility while eliminating the need for separate cleaning operations. The integrated design ensures both electrodes are replaced together, so if one electrode needs cleaning, both are replaced as a unit, significantly reducing the cleaning burden on the user.
3Reliability
If close contact between electrodes is maintained, then liquid leakage is prevented, but electrode replacement becomes more difficult
Solution Approach 1:
The patent employs a dynamic pressing mechanism that maintains close contact between the ISE electrode and reference electrode during operation to prevent liquid leakage. The pressing unit can apply sufficient force to ensure reliable contact, yet can be easily released when replacement is needed, providing both reliability during use and ease of replacement when required.

AI summary
ProblemProvided is an electrolyte analyzer that allows reducing a load of a user in a replacement work compared with conventional one.SolutionAn electrolyte analyzer includes an ISE electrode 1 that includes at least one electrode, a reference electrode 2 that includes at least one electrode different from the ISE electrode 1, and a housing 200 that houses the electrodes of the ISE electrode 1 and the reference electrode 2. The housing 200 includes a pressing unit that presses the electrodes to one another, a first press switching unit 210 that switches the ISE electrode 1 between a secured state and a released state, and a second press switching unit 215 that switches the reference electrode 2 between a secured state and a released state. The ISE electrode 1 and the reference electrode 2 are each switched between the secured state and the released state.
