Ion Wind Device Segmented Counter Electrode Ozone Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ion wind generation devices face challenges in distributing ions and ozone evenly throughout a room, requiring additional fans to push the ion wind, which leads to ion dilution and high ozone concentrations near the nozzle, potentially causing unintentional bleaching of nearby items.
Innovation Solution
An ion wind generation device with an electrode pair featuring a discharge electrode body and a counter electrode body with strategically positioned end portions that facilitate selective corona discharge, reducing ozone concentration near the nozzle without the need for filters or additional fans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If additional fans are used to push ion wind, then ions can be distributed throughout the room, but ion concentration is diluted and ozone concentration near the nozzle increases
Solution Approach 1:
The counter electrode body is divided into multiple end portions positioned at different locations and orientations. This segmentation creates multiple discrete corona discharge zones that collectively cover a wider area, enabling broad ion distribution without requiring mechanical fans that would dilute the ion concentration.
Solution Approach 2:
The end portions of the counter electrode body are arranged in three-dimensional space with different orientations (some facing the discharge electrode, some facing away, some oriented laterally). This spatial arrangement extends the ion delivery range in multiple directions simultaneously, achieving wide coverage without linear expansion that would require fan assistance.
2Productivity
If additional fans are used to push ion wind, then ion delivery range is extended, but device complexity increases
Solution Approach 1:
The counter electrode body serves multiple functions simultaneously: it acts as a discharge electrode for generating ions, a structural support for positioning multiple end portions, and a directional control element for ion distribution. This multi-functionality eliminates the need for separate fan components, maintaining device simplicity while achieving extended ion delivery range.
Solution Approach 2:
The corona discharge itself generates the ion wind flow that distributes ions throughout the space. The electric field between the discharge electrode and counter electrode creates a self-sustaining ion flow mechanism that does not require external mechanical propulsion devices, thereby avoiding increased device complexity.
3Productivity
If corona discharge occurs near the nozzle, then ion generation is effective, but ozone concentration becomes too high causing unintentional bleaching
Solution Approach 1:
The counter electrode body is segmented into multiple end portions positioned at different distances and angles relative to the discharge electrode. This segmentation distributes the corona discharge activity across multiple localized zones, preventing excessive ozone accumulation in any single area while maintaining overall ion generation efficiency.
Solution Approach 2:
Different end portions of the counter electrode body are positioned with varying orientations and distances from the discharge electrode, creating localized discharge zones with different ozone generation characteristics. Areas facing away from the discharge electrode experience lower ozone concentration, preventing bleaching while maintaining ion generation in other zones.
