Electrolyte Analysis Device Peeling Detection via Potential Difference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrolyte analysis devices face challenges in determining whether ion selective films are peeled from electrode layers, making it difficult to ensure the reliability of measurement results due to the small size and transparency of the films, making visual inspection impractical.
Innovation Solution
An electrolyte analysis device with a substrate design featuring a main electrode layer and an auxiliary electrode layer, where the ion selective film is in contact with the main base portion, and the auxiliary electrode layer is separated, allowing for the determination of film peeling by measuring the potential difference between the main and auxiliary base portions when an electrolyte is in contact with the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the ion selective films are made small and transparent to reduce device size, then the device becomes more compact and disposable, but it becomes difficult to visually determine whether the films are peeled from the electrode layers
Solution Approach 1:
The patent applies color changes by providing a visual indicator system where the substrate displays different visual states based on film attachment status. When the ion selective film is properly attached, the substrate shows one visual appearance, and when peeled, it shows a different visual appearance, enabling easy detection without requiring the film itself to be visible.
Solution Approach 2:
The patent introduces an intermediary visual indicator system that mediates between the invisible film attachment status and the user's need to detect peeling. Instead of directly observing the film, the user observes the visual indicator on the substrate that changes state based on film attachment, solving the detection difficulty caused by small, transparent films.
2Ease of operation
If visual inspection is used to detect film peeling, then the detection method is simple, but it becomes impractical when the films are small and transparent
Solution Approach 1:
The patent resolves this contradiction by implementing visual indicators that change appearance based on film attachment status. This maintains the simplicity of visual inspection while overcoming its limitation with small, transparent films, thereby ensuring both ease of operation and measurement reliability.
Solution Approach 2:
The patent segments the detection function by separating the film itself from the visual indicator. The visual indicator is provided on the substrate rather than on the film, allowing the indicator to be larger and more visible while the film remains small and transparent, thus maintaining both simplicity and reliability.
3Adaptability or versatility
If the ion selective films are rubbed during improper handling, then the films may be peeled from the electrode layers, but there is no reliable way to detect this damage
Solution Approach 1:
The patent implements feedback by providing visual indicators that immediately reflect the attachment status of the ion selective film. When improper handling causes peeling, the visual indicator changes appearance, providing immediate feedback to the user about the damage, thereby enabling reliable detection of handling-induced peeling.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the substrate with visual indicators that are ready to detect peeling before measurement occurs. This allows the system to detect damage from improper handling before it affects measurement reliability, enabling users to identify and discard damaged sensors in advance.

AI summary
An electrolyte analysis device includes a substrate extending in one direction, a main base portion provided on a main surface of the substrate, an ion selective film provided to be in contact with the main base portion so as to cover the main base portion, and an auxiliary base portion provided on the substrate. In a state where the electrolyte is in contact with a side of one end of the substrate so as to cover the side of the one end, a peeling determination unit obtains a potential of the main base portion and a potential of the auxiliary base portion, respectively. Whether or not the ion selective film is peeled from the main base portion is determined based on a potential difference between an obtained potential of the main base portion and an obtained potential of the auxiliary base portion.
