Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the micro electrostatic filter uses dielectric material to form a strong electric field for air purification, then the purification efficiency is improved, but in high humidity environments the current leakage and arcing occur due to incomplete sealing and structural issues
Solution Approach 1:
The filter is divided into multiple stacked insulating dielectric plates with electrode materials, creating segmented hollow microporous channels. This segmentation allows for better control of the electric field distribution and improves sealing between sections, reducing current leakage paths while maintaining purification efficiency through the cumulative effect of multiple stages.
Solution Approach 2:
The patent transitions from a planar electrode structure to a three-dimensional stacked configuration of insulating dielectric plates with hollow microporous channels. This dimensional change creates multiple air channels in series, increasing the effective purification area while the vertical stacking provides natural sealing paths that reduce leakage in high humidity environments.
2Force
If the electrode material is positioned closer to the edges to increase electric field strength, then the attraction to charged particles is improved, but the leakage paths increase and current leakage occurs
Solution Approach 1:
The electrode material is selectively positioned only on specific surfaces of the insulating dielectric plates, with different electrode configurations on different faces. This local quality approach concentrates the electric field where needed for particle attraction while leaving other areas with natural insulation, thereby reducing overall leakage paths while maintaining strong attraction forces in the air channels.
3Productivity
If the power supply provides high voltage to maintain strong electric field for purification, then the bacteriostatic disinfection efficiency is improved, but the risk of arcing and ignition increases in high humidity
Solution Approach 1:
Insulating dielectric plates serve as intermediary elements between the electrode materials and the high humidity environment. These plates with hollow microporous channels provide a controlled medium that allows the strong electric field to function for disinfection while the dielectric material itself prevents direct contact between moisture and electrodes, reducing arcing and ignition risks.
4Ease of manufacture
If the filter structure is simplified to reduce manufacturing cost, then the ease of manufacture is improved, but the sealing completeness deteriorates leading to current leakage
Solution Approach 1:
The patent combines multiple functions into the insulating dielectric plates: they provide structural support, create the hollow microporous air channels, serve as sealing elements between stacked sections, and act as insulators to prevent current leakage. This merging of functions achieves reliable sealing without requiring complex additional sealing components, maintaining ease of manufacture through straightforward stacking and hot fusion bonding.
