Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional discharge electrode configuration is used, then the device structure is simple, but the generation amount of active components is limited
Solution Approach 1:
The discharge electrode is divided into a protruding distal end portion and a base portion, creating multiple discharge regions. The counter electrode is configured with a discharge portion that extends along the circumference, segmenting the discharge space into multiple zones that collectively increase active component generation
Solution Approach 2:
The discharge portion of the counter electrode extends along the circumference centered on the distal end portion of the discharge electrode, adding a circumferential dimension to the discharge configuration. This dimensional expansion increases the discharge path length and surface area, thereby increasing active component generation without significantly complicating the overall device structure
2Quantity of substance
If the discharge path is extended to increase active component generation, then more active components are produced, but the discharge energy requirement increases
Solution Approach 1:
The distal end portion of the discharge electrode is given a protruding configuration with a smaller radius of curvature compared to the base portion. This creates localized high electric field intensity at the distal end, enabling efficient discharge initiation and maintaining low overall energy consumption while extending the discharge path through the circumferential configuration of the counter electrode's discharge portion

Implementation Method 1
generate a discharge between the discharge electrode and the counter electrode by applying a voltage between the discharge electrode and the counter electrode
Implementation Method 2
liquid is supplied to the discharge electrode by a liquid supply unit. Therefore, the liquid is electrostatically atomized by the discharge, and nanometer-sized charged fine particle liquid containing radicals inside is generated
