Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fluorine-containing coating is used to achieve non-stick function, then non-stick performance is improved, but wear resistance deteriorates
Solution Approach 1:
The patent applies composite materials by combining fluorine-containing coating with ceramic coating layers to create a multi-layer non-stick coating system. The fluorine-containing coating provides non-stick properties while the ceramic coating layers provide wear resistance and structural support, resolving the contradiction between non-stick performance and wear resistance through material composition
2Reliability
If ceramic coating is used to improve wear resistance, then hardness is improved, but thermal expansion compatibility deteriorates
Solution Approach 1:
The patent applies local quality by creating a multi-layer structure where different layers have different properties optimized for their specific functions. The ceramic coating layers provide hardness and wear resistance where needed, while the intermediate fluorine-containing coating layer acts as a buffer to accommodate thermal expansion differences, preventing cracking during heating and cooling cycles
3Ease of operation
If non-stick coating is applied to achieve non-stick effect, then ease of cleaning is improved, but service life deteriorates
Solution Approach 1:
The patent uses composite materials with a multi-layer structure where the fluorine-containing coating provides non-stick properties for easy cleaning, while the underlying ceramic coating layers provide durability and wear resistance to extend service life. This composite approach allows both easy cleaning and long service life to coexist
