1Stability of the object's composition
If ceramic material is used for the ion generator, then the structural stability is improved, but the manufacturing cost increases and corrosion resistance deteriorates due to electrode oxidation
Solution Approach 1:
The patent uses a composite structure combining plastic substrate with metal-coated electrodes. The plastic plate provides structural stability while the gold coating on copper electrodes prevents oxidation, creating a composite material system that resolves the contradiction between structural integrity and corrosion resistance.
Solution Approach 2:
The patent replaces expensive ceramic materials with a more economical plastic substrate combined with protective metal coatings. This approach uses cost-effective materials (plastic and gold-coated copper) to achieve the required performance, reducing manufacturing cost while maintaining reliability through the protective coating system.
