Ion Generator Upstream Counter Electrode for Ion Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ion generators face challenges in maintaining a stable generation and conveyance of air ions due to decreased electric field intensity and ion balance, leading to incomplete neutralization of charged targets.
Innovation Solution
The ion generator positions the counter electrode on the upstream side of the air flow with respect to the discharge electrode, reducing ion adsorption and maintaining electric field intensity, thereby increasing ion conveyance without affecting generation amounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the counter electrode is disposed on the outer periphery near the tip of the discharge electrode to generate air ions, then the corona discharge occurs easily, but the electric field intensity decreases as air ions are adsorbed by the counter electrode, degrading ion balance
Solution Approach 1:
The patent repositions the counter electrode from a lateral position (near the tip of the discharge electrode) to an upstream position in the air flow direction. This spatial reconfiguration changes the relationship between the electrodes from a side-by-side arrangement to a sequential arrangement along the air flow path, allowing the counter electrode to be upstream of the discharge electrode in the flow direction while maintaining effective ion generation and preventing ion balance degradation
2Reliability
If the counter electrode is positioned upstream in the air flow, then ion adsorption is reduced and electric field intensity is maintained, but the structural configuration becomes different from conventional designs
Solution Approach 1:
The patent utilizes the air flow direction as a new dimensional reference for electrode positioning. Instead of arranging electrodes based on lateral proximity, the design positions them sequentially along the air flow path, with the counter electrode upstream and the discharge electrode downstream. This approach maintains simple electrode structures while achieving improved electric field stability through the new spatial arrangement
