Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If plate electrodes are used in plasma generation devices, then the device structure is simple, but the plasma coverage area is extremely small (micrometer scale)
Solution Approach 1:
The electrode is divided into multiple isolated electrode sections with hollowed-out structures between them. Each electrode section generates plasma that spreads to adjacent areas, and the hollowed-out regions allow plasma from different sections to connect, collectively covering a much larger area than a solid plate electrode of the same material quantity.
Solution Approach 2:
The electrode transitions from a two-dimensional plate structure to a three-dimensional hollowed-out structure with depth. This vertical hollowing allows plasma to be generated and spread in multiple spatial dimensions, significantly increasing the effective plasma coverage area while using the same amount of electrode material.
2Productivity
If plate electrodes are used, then the electrode material usage is minimal, but the purification effect is insufficient due to small plasma coverage area
Solution Approach 1:
By segmenting the electrode into isolated sections with hollowed-out structures, each section acts as an independent plasma source. The plasma from multiple sections merges in the hollowed-out regions, creating a large-scale plasma field that significantly enhances purification efficiency compared to a single solid plate electrode.
Solution Approach 2:
The hollowed-out electrode structure functions similarly to a porous structure, where the hollowed regions allow plasma to penetrate and spread throughout the structure. This increases the interaction between plasma and the substances being purified (air, water, fabrics, etc.), thereby improving purification efficiency.
3Area of stationary object
If the electrode is made solid, then the structural strength is high, but the plasma coverage area remains limited to micrometer scale
Solution Approach 1:
The electrode is segmented into multiple isolated sections rather than a continuous solid structure. Each section maintains sufficient structural strength independently, while the collective arrangement of sections with hollowed-out spaces between them creates a large plasma coverage area. The segmentation allows both strength and plasma coverage to be optimized.
