Solution Overview
Problem
The accumulation of scale on the cathode in electrolytic liquid generation devices reduces the spatial density of ozone, leading to decreased dissolution efficiency and overall generation efficiency of electrolytic liquids.
Innovation Solution
The electrolytic liquid generation device includes an electrolysis unit with a conductive film sandwiched between electrodes, where a space part penetrates the unit, allowing liquid to flow through, and the housing design features a flow path with varying cross-sectional areas to enhance the flow of liquid and reduce scale adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a flow path is formed between the housing and cathode, then liquid can flow through the device, but scale accumulates on the cathode surface
Solution Approach 1:
The invention extracts the harmful flow path between the housing and cathode by introducing a through-hole in the cathode that directs liquid flow through the electrolysis unit itself. This removes the stagnant outer flow path where scale accumulated, while maintaining necessary liquid circulation for electrolysis operation.
Solution Approach 2:
The through-hole in the cathode acts as an intermediary structure that redirects liquid flow from the harmful outer path to a beneficial inner path. This mediator changes the flow trajectory to prevent scale accumulation while ensuring proper liquid distribution across the electrolysis surfaces.
2Device complexity
If scale accumulates on the cathode, then the device structure remains simple, but ozone spatial density varies and dissolution efficiency decreases
Solution Approach 1:
The invention segments the flow path into distinct regions: an outer flow path for bulk liquid circulation and an inner flow path through the cathode for targeted electrolysis. This segmentation prevents scale accumulation in critical areas while maintaining overall structural simplicity and high generation efficiency.
3Device complexity
If liquid flows only through the outer path, then the housing structure is simple, but ozone dissolution efficiency decreases
Solution Approach 1:
The invention adds a third dimensional aspect to the flow path by creating a through-hole that penetrates the cathode thickness. This transforms the flow from a two-dimensional outer path to a three-dimensional structure with both outer and inner flow paths, enhancing ozone dissolution efficiency while maintaining housing simplicity.
