Solution Overview
Problem
Conventional space purification devices generate electrolyzed water containing chloride ions, which easily contaminates and deteriorates electrodes due to contact with air, and lack the ability to release active oxygen species in amounts suitable for varying use environments.
Innovation Solution
The device separates the water storage into an electrolytic bath and a mixing bath, generating electrolyzed water in the electrolytic bath and supplying it to the mixing bath where it mixes with air, while a controller adjusts the supply amount based on environmental variables and purification settings to optimize active oxygen species release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the device generates electrolyzed water containing chloride ions and releases it directly, then active oxygen species are released for purification, but the chloride ions contaminate and deteriorate the electrodes
Solution Approach 1:
The water storage is divided into two separate baths: an electrolytic bath for generating hypochlorous acid water and a mixing bath for mixing it with pure water. This segmentation allows the electrolytic bath to maintain high-concentration hypochlorous acid water without contamination, while the mixing bath handles the dilution process, preventing chloride ion contact with electrodes during mixing.
Solution Approach 2:
Pure water acts as an intermediary substance that is introduced into the mixing bath. This intermediary allows the hypochlorous acid water to be diluted without direct contact between chloride ions and the electrodes during the mixing process, thereby protecting the electrodes from deterioration.
2Adaptability or versatility
If the device uses a fixed supply amount of hypochlorous acid water, then the structure is simple, but it cannot adapt to varying purification requirements in different use environments
Solution Approach 1:
The controller dynamically adjusts the supply amount of hypochlorous acid water based on real-time detection of environmental variables (temperature, humidity, air quality) and user-selected purification levels. This dynamic adjustment allows the device to adapt to varying purification requirements without requiring multiple fixed-configuration units.
Solution Approach 2:
The control system incorporates feedback mechanisms that continuously monitor environmental conditions and purification performance, then adjust the hypochlorous acid water supply amount accordingly. This feedback loop enables the device to maintain optimal purification effectiveness across different environments while automatically compensating for variable conditions.
