Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fluorine-containing polymer compositions are used for sealing materials, then heat resistance and chemical resistance are achieved, but oxygen adsorption capability is insufficient
Solution Approach 1:
The patent combines fluorine-containing polymer with non-stoichiometric silicon oxide (SiOx where 0 < x < 2) to create a composite material that simultaneously achieves heat resistance from the polymer and oxygen adsorption capability from the silicon oxide, resolving the contradiction between thermal stability and oxygen uptake
2Temperature
If fluorine-containing polymer is used in high-temperature environments, then thermal stability is maintained, but plasma resistance deteriorates
Solution Approach 1:
The composite structure combines the thermal stability of fluorine-containing polymer with the plasma resistance of non-stoichiometric silicon oxide, where the silicon oxide component provides protection against plasma damage while the polymer maintains thermal stability at high temperatures
3Stability of the object's composition
If stoichiometric silicon oxide is used, then chemical inertness is achieved, but oxygen adsorption is insufficient
Solution Approach 1:
The patent changes the compositional parameter of silicon oxide from stoichiometric (SiO2) to non-stoichiometric (SiOx where 0 < x < 2), creating deficiency sites that enable oxygen adsorption while maintaining chemical stability, thus resolving the contradiction between inertness and oxygen uptake capacity
