Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a functional layer is applied to improve slipperiness and touch feeling, then surface performance is improved, but durability deteriorates due to continuous or repeated contacts
Solution Approach 1:
The patent uses a composite material consisting of fluorine-containing (poly)ether groups and heteroatom-containing cyclic silane compounds to form a coating film that combines both slipperiness and durability. The fluorine-containing groups provide low surface energy for slipperiness, while the silane compounds form strong inter-chain interactions for durability, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The patent changes the chemical composition parameters by incorporating heteroatom-containing cyclic silane compounds with specific structures (Formulas 2 and 3) that enable ring-opening and polycondensation reactions. This parameter change allows the coating to form strong inter-chain interactions while maintaining surface properties, simultaneously improving durability and preserving slipperiness.
2Ease of operation
If conventional coating materials are used, then initial surface properties are achieved, but wear resistance decreases after frequent friction
Solution Approach 1:
The patent applies preliminary action by forming a coating film with pre-established strong inter-chain interactions through ring-opening and polycondensation reactions of heteroatom-containing cyclic silane compounds. This preliminary structural reinforcement ensures that the coating maintains its integrity and wear resistance even after frequent friction, while preserving the initial surface properties provided by fluorine-containing groups.
Solution Approach 2:
The patent changes the molecular structure parameters by using heteroatom-containing cyclic silane compounds that undergo ring-opening and polycondensation reactions to form strong inter-chain interactions. This parameter change in the coating structure provides both initial surface properties and enhanced wear resistance, resolving the contradiction between ease of operation and strength.
