Electrolyte Analyzer Chamber Selection for Timely Consumable Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrolyte analyzers face issues with inappropriate replacement of consumable items, leading to increased frequency and reduced maximum processing performance due to mismatched remaining measurable numbers across analysis chambers.
Innovation Solution
An electrolyte analyzer with a control unit that selects analysis chambers based on the remaining measurable numbers and measurement request status of consumable items, ensuring optimal utilization and timely replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If consumable items are replaced frequently to ensure measurement accuracy, then measurement reliability is improved, but device productivity deteriorates due to increased replacement frequency
Solution Approach 1:
The control unit performs preliminary management of consumable items by tracking remaining measurable numbers and expiration dates before replacement is needed. It proactively plans replacement timing and selects optimal analysis chambers in advance, preventing urgent replacements that disrupt productivity while ensuring measurement reliability is maintained through timely replacement.
2Productivity
If multiple analysis chambers are used to increase processing capacity, then device productivity is improved, but device complexity worsens due to mismatched consumable replacement timing
Solution Approach 1:
The control unit implements a feedback mechanism that continuously monitors the remaining measurable numbers and expiration dates of consumable items in each analysis chamber. Based on this feedback, it dynamically selects which chamber to use for next measurement, ensuring balanced consumable usage across multiple chambers and simplifying replacement timing without reducing processing capacity.
3Ease of operation
If consumable items are replaced based on fixed schedules, then ease of operation is improved, but loss of time increases due to unnecessary replacements
Solution Approach 1:
The system transitions from fixed-schedule replacement to dynamic, demand-driven replacement management. The control unit adaptively determines replacement timing based on actual consumable usage patterns, remaining measurable numbers, and expiration dates, allowing replacements to occur only when necessary while maintaining ease of operation through automated tracking and chamber selection.

AI summary
There is provided an electrolyte analyzer that can appropriately replace consumable items while more exerting analysis processing performances than a conventional electrolyte analyzer does. An electrolyte analyzer includes a plurality of analysis chambers 50 having ISE electrodes 1 configured to measure the concentration of the electrolyte of a sample and a controller 29 configured to control operations in the electrolyte analyzer 100 including the analysis chambers 50. The ISE electrodes 1 of the plurality of analysis chambers 50 analyze the same analysis items. The controller 29 selects an analysis chamber 50 used for measurement from the plurality of analysis chambers 50 corresponding to the remaining measurable numbers of a plurality of ISE electrodes 1 and measurement request status.
