Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple ion boxes are connected in series with the same high-voltage power supply, then the system structure is simplified and space is saved, but the reliability decreases because failure of one ion box causes the entire system to stop working
Solution Approach 1:
The patent divides the purification system into multiple independent purification units, each with its own high-voltage power supply. This segmentation allows each unit to operate independently, so that failure of one unit does not affect the others, thereby improving system reliability while maintaining a relatively simple overall structure.
2Productivity
If the distance between high-voltage polar plates and low-voltage polar plates is reduced to increase ionization efficiency, then the purification efficiency is improved, but the risk of high-voltage ignition and arcing increases
Solution Approach 1:
The patent introduces a shielding plate with local grounding between the high-voltage and low-voltage polar plates. This creates a localized electric field distribution where the shielding plate provides electrostatic shielding in critical areas, allowing the plates to be positioned closer together for improved purification efficiency while preventing harmful ignition and arcing through localized field control.
3Reliability
If the distance between polar plates is increased to prevent arcing, then the safety is improved, but the purification efficiency decreases due to reduced ionization strength
Solution Approach 1:
The patent introduces a shielding plate as an intermediary element between the high-voltage and low-voltage polar plates. This shielding plate, connected to ground or low voltage, acts as a mediator that allows the polar plates to be positioned closer together for improved purification efficiency while preventing harmful electrical discharges, thus maintaining safety without sacrificing productivity.
