Measuring Unit Segmentation for Ion Sensor Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring devices for solution states, such as ion sensors, face issues with deterioration due to foreign matter adhesion, alteration, or scraping, leading to inaccurate measurements and the need for frequent replacements.
Innovation Solution
A measuring device with a dual-part measuring unit, where one part is in contact with the solution for measurement and the other part is isolated by a protection unit, composed of biodegradable or acid-soluble resin, allowing for extended measurement periods and reduced maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the measuring unit is continuously used to measure solution state, then measurement function is maintained, but the measuring unit deteriorates due to foreign matter adhesion, alteration, or scraping
Solution Approach 1:
The measuring unit is divided into a first part (glass electrode unit and first reference electrode unit) that contacts the solution and a second part (second reference electrode unit) that is protected by the protection unit. This segmentation allows the first part to perform measurements while the second part remains isolated and maintains high reliability for extended periods.
Solution Approach 2:
The protection unit acts as an intermediary between the second reference electrode unit and the solution. It isolates the second part from direct contact with the solution, preventing deterioration while still allowing the measurement function to be performed by the first part that is in contact with the solution.
2Measurement precision
If the measuring unit is replaced frequently to maintain measurement accuracy, then measurement precision is maintained, but user convenience deteriorates
Solution Approach 1:
By dividing the measuring unit into first and second parts with different protection levels, the system allows one part to be used while the other remains preserved. This extends the overall operational life of the measuring unit, reducing the frequency of replacements and improving user convenience while maintaining measurement precision.
Solution Approach 2:
The protection unit is designed to be biodegradable or acid-soluble, meaning it can be discarded after use while the second reference electrode unit is recovered and can be reused for future measurements, reducing waste and improving convenience.
3Reliability
If the protection unit is made from durable material to prevent deterioration, then protection effectiveness is improved, but environmental compatibility deteriorates
Solution Approach 1:
The protection unit is made from materials with specific properties (biodegradable or acid-soluble) that change their state over time or under specific conditions. These parameter changes allow the protection unit to provide effective protection during use while subsequently degrading in an environmentally friendly manner, eliminating the need for durable but harmful materials.

AI summary
A measuring device 1 according to the present disclosure measures a state of a solution L. The measuring device 1 includes a measuring unit 10 that outputs a measurement signal associated with the state of the solution L, a protection unit 20 attached to the measuring unit 10, and a controller 40 that obtains the information on the state of the solution L on the basis of a measurement signal output from the measuring unit 10. The measuring unit 10 has a first part P1 in a usable state that contributes to output of the measurement signal by coming into contact with the solution L, and a second part that is isolated from the solution L by the protection unit 20 and is in a standby state for measurement.
