Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional piezoelectric transformer design is used, then the device structure is simple, but the ionization degree and ozone production are insufficient
Solution Approach 1:
The surface structure is divided into multiple protruding segments that create multiple discharge initiation points along the contour. This segmentation allows the gas discharge to occur at multiple locations simultaneously, increasing the overall ionization degree and ozone production without requiring a single high-voltage feed line, thus maintaining structural simplicity while improving productivity
Solution Approach 2:
The protruding surface structure segments create localized regions with different electric field characteristics. The contour regions with protruding segments have enhanced electric field strength that facilitates discharge initiation, while other regions maintain different properties. This local quality variation enables efficient plasma generation at specific locations without complicating the overall device structure
2Productivity
If high-voltage feed lines and ignition units are used, then the plasma generation is effective, but the device complexity and fault susceptibility increase
Solution Approach 1:
The piezoelectric transformer with protruding surface structure generates its own high-voltage output directly at the discharge points without requiring external high-voltage feed lines or separate ignition units. The surface structure itself facilitates the discharge initiation through its geometric configuration, allowing the system to serve itself and eliminate additional components, thereby reducing device complexity and fault susceptibility while maintaining effective plasma generation
Solution Approach 2:
The functions of the piezoelectric transformer, high-voltage feed lines, and ignition units are merged into a single integrated structure. The protruding surface segments on the piezoelectric transformer directly create the conditions for discharge initiation, combining multiple functions into one component and eliminating the need for separate high-voltage feed lines and ignition units, thus reducing the number of components and potential failure points
3Productivity
If the surface structure width is smaller than the piezoelectric transformer width, then the discharge initiation points are concentrated, but the plasma distribution may be non-uniform
Solution Approach 1:
The surface structure is segmented into multiple protruding segments distributed along the contour of the piezoelectric transformer. This segmentation creates multiple discrete discharge initiation points that are spatially distributed, allowing the plasma to be generated at multiple locations simultaneously. The segments are arranged to ensure homogeneous plasma distribution across the treatment area while maintaining the width constraint for efficient discharge initiation
Solution Approach 2:
Instead of distributing discharge points only in one dimension across the width, the protruding segments are arranged along the contour in a distributed pattern that utilizes the two-dimensional surface area. This dimensional distribution ensures that discharge initiation points are spread out appropriately to achieve homogeneous plasma coverage while maintaining the width constraint for efficient discharge
