Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively and efficiently produce a large amount of sterilizing water with a consistent concentration of sterilizing components like hypochlorous acid for extended periods, especially in open-type livestock barns and for various hygiene applications, due to limitations in electrode durability and power consumption.
Innovation Solution
A set of sterilizing electrodes with a thick platinum catalyst layer, formed as a thin plate and stacked on a conductive body, allows for continuous electrolysis by creating multiple electricity paths between electrodes, enabling the production of sterilizing water with a consistent concentration of hypochlorous acid for an extended time while minimizing platinum consumption and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a thin platinum plating layer is used on electrodes, then the initial production of sterilizing water is possible, but the electrodes cannot maintain consistent sterilizing component concentration for extended periods due to rapid platinum consumption
Solution Approach 1:
The patent changes the thickness parameter of the platinum layer from conventional thin plating (micrometer scale) to thick plate (millimeter scale). This parameter change transforms the electrode from rapid platinum consumption to sustained long-term operation, directly resolving the contradiction between reliability and duration by ensuring consistent sterilizing component concentration over extended periods
Solution Approach 2:
The patent transitions from a two-dimensional thin plating approach to a three-dimensional thick plate structure. This dimensional change provides sufficient platinum material volume to maintain consistent surface concentration during prolonged electrolysis, solving the problem of rapid platinum depletion that limits operational duration
2Productivity
If high current is supplied for extended periods to produce large amounts of sterilizing water, then productivity increases, but platinum consumption accelerates and electrode durability decreases
Solution Approach 1:
The patent changes the platinum layer thickness parameter to millimeter scale, providing a large material reserve that can withstand high current densities over extended periods. This enables sustained high-productivity operation without the rapid platinum depletion that would otherwise occur, resolving the contradiction between productivity and substance loss
Solution Approach 2:
The patent prepares a thick platinum plate structure in advance before electrolysis begins. This preliminary preparation of sufficient material volume allows the electrode to withstand high current loads and extended operation without depleting platinum, enabling high productivity while minimizing platinum consumption rate
3Device complexity
If conventional thin platinum plating is used, then device complexity is low, but the electrodes require frequent replacement and maintenance
Solution Approach 1:
The patent changes the platinum layer thickness from thin plating to thick plate structure. This single parameter change maintains structural simplicity while dramatically extending electrode service life, reducing replacement frequency without adding complex components or systems
4Quantity of substance
If extended electrolysis operation is performed to produce sufficient sterilizing water, then the amount of sterilizing water increases, but power consumption increases proportionally
Solution Approach 1:
The thick platinum plate enables continuous electrolysis operation without interruption for electrode replacement or maintenance. This continuity ensures that useful action (sterilizing water production) proceeds uninterrupted, optimizing the ratio of sterilizing water quantity to power consumption by eliminating downtime and maintaining steady-state efficient operation
