Engineering Contradiction Analysis
1Productivity
If plasma purifiers are used to achieve better ionization purification performance, then purification performance is improved, but by-products such as ozone are generated
Solution Approach 1:
The air purification device is divided into separate functional modules: a plasma module for strong ionization purification and a positive/negative ion module for supplementary purification. This segmentation allows the plasma module to operate at optimized power levels, reducing excessive by-product generation while maintaining high purification effectiveness through coordinated multi-module operation.
Solution Approach 2:
The device dynamically adjusts operating parameters including power supply voltage, ion generation levels, and module activation states based on real-time air quality sensing. By changing operational parameters rather than maintaining fixed high-power plasma generation, the system achieves high purification performance while minimizing by-product formation through precise parameter control.
2Adaptability or versatility
If multiple independent power supply modules are used for positive/negative ion module and plasma module, then operational independence is improved, but device complexity and cost increase
Solution Approach 1:
A single power supply module is designed to serve multiple functions by providing power to both the plasma module and the positive/negative ion module. This multi-functional power supply maintains operational independence of each purification module while reducing overall device complexity and cost, eliminating the need for separate power supplies for each module.
Solution Approach 2:
The power supply functions for the plasma module and positive/negative ion module are merged into a single integrated power supply unit. This combination reduces the total number of components, simplifies the device structure, and lowers cost while preserving the ability to independently control each purification module through the shared power supply.
