Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional light control member structure is used, then the manufacturing process is simple, but the durability and reliability are insufficient
Solution Approach 1:
A surface modification layer comprising a silane compound is introduced as an intermediary between the base layer and the light control pattern. This surface modification layer includes a silane compound with specific functional groups that enhance adhesion and bonding strength, thereby improving durability and reliability without fundamentally changing the overall device structure
Solution Approach 2:
The patent employs composite material structure by combining the base layer, surface modification layer with silane compound, and light control pattern. The silane compound in the surface modification layer creates a composite interface that strengthens the bonding between the base layer and light control pattern, achieving improved reliability through material composition rather than structural complexity
2Stability of the object's composition
If the bonding between light control patterns and base layer is weak, then the manufacturing process is simple, but the stability and performance deteriorate
Solution Approach 1:
The patent changes the chemical parameters of the interface between base layer and light control pattern by introducing a surface modification layer containing silane compounds with specific functional groups. This chemical parameter change enhances bonding strength and stability without requiring complex manufacturing processes, as the surface modification can be achieved through standard coating and curing techniques
