Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the composition and composition ratio of enamel are changed to improve thermal resistance, chemical resistance, wear resistance, and pollution resistance, then the resistance performance is improved, but the electrostatic performance of the enamel is reduced
Solution Approach 1:
The patent applies composite materials by combining glass frit with specific additives (metal oxides such as boron oxide, zinc oxide, bismuth oxide, and organic compounds like polymethylhydrosiloxane) to create an enamel composition that achieves both improved resistance performance and maintained electrostatic performance. The composite formulation allows synergistic effects where each component contributes to different performance aspects simultaneously.
Solution Approach 2:
The patent employs parameter changes by precisely controlling the composition ratios of various components in the enamel, including specific weight percentages of glass frit (90-99 wt%), metal oxides (1-10 wt%), and organic compounds (0.1-5 wt%). By adjusting these parameters within optimized ranges, the patent achieves both enhanced resistance properties and preserved electrostatic performance.
2Reliability
If the electrostatic performance of the enamel is reduced, then the coating performance is reduced, but the resistance performance can be improved
Solution Approach 1:
The patent uses organic compounds, particularly polymethylhydrosiloxane and its derivatives, as intermediary substances that bridge the gap between glass frit particles. These intermediaries improve the coating performance by enhancing particle dispersion and adhesion, while the specific chemical structure of these intermediaries also contributes to maintaining electrostatic performance alongside the resistance properties.
