Engineering Contradiction Analysis
1Force
If large voltages are applied to generate sufficient electric field, then electric field strength is improved, but voltage breakdown occurs
Solution Approach 1:
The patent applies a dielectric coating to the electrodes, which changes the electrical parameters of the system. The dielectric layer modifies the electric field distribution and increases the breakdown voltage, allowing stronger electric fields to be generated without causing voltage breakdown. This directly resolves the contradiction by enabling higher electric field strength while maintaining system reliability.
2Force
If large voltages are applied to generate sufficient electric field, then electric field strength is improved, but spurious charge loss increases
