Engineering Contradiction Analysis
1Productivity
If conventional groove structures are used on electrodes, then gas flow is improved, but ozone production efficiency cannot be further enhanced
Solution Approach 1:
The electrode surface is segmented into multiple trench grooves that divide the discharge space into distinct regions. This segmentation creates multiple localized discharge zones, increasing the overall ozone production efficiency while maintaining a manageable structural complexity through standardized groove patterns
Solution Approach 2:
Specific geometric parameters of the trench grooves are optimized to enhance performance: the pitch ratio P/D is set to 0.0020-0.0150 and the volume ratio VT/VG is set to 0.016-0.203. These parameter changes maximize gas flow efficiency and discharge uniformity, thereby improving ozone production without excessive structural complexity
2Productivity
If higher voltage is applied to increase ozone concentration, then production efficiency improves, but energy consumption and electrode damage increase
Solution Approach 1:
The invention changes the geometric parameters of the electrode structure (trench groove pitch and volume ratios) to optimize the discharge characteristics. This allows achieving higher ozone concentrations through improved gas flow and discharge uniformity rather than simply increasing voltage, thereby reducing energy consumption and electrode stress
Solution Approach 2:
The trench grooves create localized regions with optimized electric field distribution and gas flow characteristics. This local optimization ensures efficient ozone production in each discharge zone, achieving high overall concentration without requiring excessive voltage that would increase energy consumption and electrode damage
3Productivity
If trench grooves are added to improve gas flow, then ozone production efficiency increases, but pressure loss increases
Solution Approach 1:
The pitch ratio P/D and volume ratio VT/VG of the trench grooves are carefully optimized to balance gas flow enhancement with pressure loss minimization. These parameter changes ensure that the grooves improve discharge uniformity and ozone production efficiency while maintaining acceptable pressure characteristics for practical operation
