Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a functional layer is applied on the display panel surface to improve touch screen performance, then surface slipping and sense of touch are improved, but durability deteriorates due to continuous contact and frequent friction
Solution Approach 1:
The patent uses a composite material comprising silane-modified polyether and fluorinated polyether compounds to form a coating layer that combines the tactile benefits of functional layers with enhanced durability through cross-linked bonding and fluorine-containing groups that provide abrasion resistance
Solution Approach 2:
The patent changes the chemical composition parameters by incorporating silane groups that undergo cross-linking reactions and fluorine-containing groups that enhance durability, transforming the material properties to achieve both good sense of touch and high durability
2Ease of operation
If a functional layer is applied to improve touch screen performance, then surface properties are enhanced, but phase stability deteriorates due to continuous contact
Solution Approach 1:
The patent employs a composite material system with silane-modified polyether and fluorinated polyether that form a cross-linked network structure, providing both enhanced surface properties and improved phase stability through the stable siloxane bonds and fluorine-containing groups
Solution Approach 2:
The silane-modified polyether acts as an intermediary that forms cross-linked bonds between polymer chains, serving as a stable structural framework that maintains phase stability while allowing the fluorinated polyether to provide enhanced surface properties
