Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the collecting electrode uses a flat surface design, then the device structure is simple, but the absorption capability and purification efficiency are reduced
Solution Approach 1:
The collecting electrode surface is designed with convex projections instead of a flat surface. These curved convex structures increase the surface area and improve the absorption capability of the collecting electrode, thereby enhancing the purification efficiency while maintaining manufacturing feasibility through standard molding processes.
2Power
If high voltage is applied to the generating electrode, then the plasma field strength increases and purification performance improves, but discharge risk increases
Solution Approach 1:
The patent incorporates a discharge monitoring circuit that detects discharge signals from the high-voltage generating electrode in real-time. When discharge is detected, the system provides feedback to adjust or reduce the voltage, preventing continuous discharge and ensuring safe operation while maintaining high plasma field strength for effective purification.
Solution Approach 2:
The patent designs the electrode structure with specific spacing and geometric configurations between the generating electrode and collecting electrode. This pre-designed structural arrangement creates natural insulation and spacing that cushions against discharge before it occurs, allowing high voltage operation while maintaining reliability.
3Device complexity
If HEPA filter screens are used for air purification, then the device structure is simple, but the absorption effect attenuates seriously over time after dust accumulation
Solution Approach 1:
The patent replaces the mechanical HEPA filter screen system with a high-voltage plasma field system. Instead of relying on physical filtration that clogs over time, the system uses electrical fields to charge and collect particles continuously. This substitution maintains simplicity while providing durable, long-term purification performance without the absorption effect attenuation seen in traditional filters.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The enhanced collecting electrode design improves purification efficiency, while the discharge monitoring circuit provides timely protection against high-voltage discharges, enhancing both performance and safety.
Implementation Method 1
The generating electrode forms a plasma field under the action of a high voltage. Protein structures on the surfaces of bacteria and viruses in the air passing through the plasma field are damaged so as to kill the bacteria and the viruses, and harmful organic molecules including formaldehyde and the like are decomposed into water and carbon dioxide under the action of high-energy electrons and strong oxidizing free radicals.
Implementation Method 2
harmful organic molecules including formaldehyde and the like are decomposed into water and carbon dioxide under the action of high-energy electrons and strong oxidizing free radicals
Implementation Method 3
A high-voltage electric field of the generating electrode electrically charges some air, and enables the air to move under the action of a force of the electric field to collide with dust particles in the air and electrically charge the dust particles.
Implementation Method 4
When moving to the vicinity of a collecting electrode with an opposite electric charge, the electrically charged particles are adsorbed by the collecting electrode due to electrostatic adsorption.
Implementation Method 5
Those not adsorbed reach a repelling electrode with the same electric charge and are pushed back to the collecting electrode due to a repellent action of the same electric charges, thereby improving a particle clearing effect to above 99%.
Implementation Method 6
Besides, the plasma field generates a plasma flow, so as to produce sufficient air speed to circulate indoor air without a fan, thereby saving energy noiselessly.
