Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional potentiometry with ion selective electrodes is used to measure electrolytes, then the measurement method is simple and well-established, but the devices cannot adequately separate electrolytes and experience dissociation issues when electrolytes are in water
Solution Approach 1:
The device separates the measurement process into distinct functional zones: a dielectric barrier layer that prevents ion dissociation, a measurement chamber for concentrated electrolyte placement, and electrode regions for voltage detection. This segmentation allows electrolytes to be measured without the dissociation problems that occur in traditional aqueous environments.
Solution Approach 2:
A dielectric material is introduced as an intermediary barrier between the electrodes and the electrolyte sample. This dielectric layer mediates the interaction by preventing direct contact between ions and water molecules, thereby eliminating dissociation while still allowing the electric field to function for measurement.
2Ease of operation
If electrolytes are measured in aqueous solution using conventional methods, then the measurement process is straightforward, but water molecules solvate ions and cause dissociation that interferes with accurate measurement
Solution Approach 1:
The invention extracts the harmful element (water) from the measurement system by using a dielectric barrier that prevents water molecules from contacting and solvating the ions. This allows ions to be measured in their native state without dissociation, improving precision while maintaining ease of operation through simple electrolyte placement.
3Adaptability or versatility
If portable and handheld electrolyte measurement devices are developed, then device portability and accessibility are improved, but adequate electrolyte separation and measurement accuracy become more challenging
Solution Approach 1:
The invention changes the physical parameters of the measurement environment by using a dielectric barrier to create a non-aqueous measurement zone. This parameter change (from aqueous to dielectric-separated environment) enables accurate electrolyte measurement in compact portable devices without the dissociation problems that would otherwise limit portability.

AI summary
A system, device and apparatus for measuring electrolytes, where an electrical charge is applied to a measurement portion to draw ions from a liquid to a gel-solution via at least one electric field. The gel-solution containing the extracted ions is excited with light of a predetermined wavelength from an emitter. A receiver detects the illumination of the ions as a result of the excited gel-solution, and a processor converts the detected intensities of the illumination to a biologically useful value representing ionic concentration.
