Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multi-layer coating processes are used for window manufacturing, then comprehensive protective functions (anti-reflection, anti-glare, anti-fingerprint) can be achieved, but manufacturing complexity and costs increase
Solution Approach 1:
The patent combines multiple protective functions (anti-reflection, anti-glare, anti-fingerprint) into a single coating layer. This single layer contains porous silica for anti-reflection, fumed silica for anti-glare, and fluorinated compounds for anti-fingerprint properties, eliminating the need for separate coating processes for each function.
Solution Approach 2:
The coating layer uses composite materials comprising porous silica particles, fumed silica particles, and fluorinated organic compounds. This composite structure enables multiple protective functions to be achieved simultaneously within one layer, reducing manufacturing complexity while maintaining comprehensive protection.
2Reliability
If multiple coating layers are applied to provide anti-reflection, anti-glare, and anti-fingerprint functions, then functional performance is improved, but manufacturing time and costs increase
Solution Approach 1:
Multiple protective functions are merged into a single coating application process. The coating composition contains all necessary components (porous silica, fumed silica, fluorinated compounds) that provide anti-reflection, anti-glare, and anti-fingerprint properties simultaneously, eliminating sequential coating steps.
Solution Approach 2:
The single coating layer is designed to perform multiple functions universally. It provides anti-reflection through porous silica, anti-glare through fumed silica, and anti-fingerprint through fluorinated compounds, making one layer sufficient for comprehensive protection rather than requiring specialized layers for each function.
3Device complexity
If a single-layer coating is used to simplify manufacturing, then manufacturing complexity is reduced, but achieving comprehensive protective functions becomes difficult
Solution Approach 1:
The single coating layer uses a composite material system containing porous silica particles for anti-reflection, fumed silica particles for anti-glare, and fluorinated organic compounds for anti-fingerprint resistance. This composite approach enables one layer to deliver comprehensive protective functions that would traditionally require multiple separate layers.
Solution Approach 2:
The coating incorporates porous silica particles that create a gradient refractive index structure for effective anti-reflection. The porous structure also contributes to the overall protective functionality while maintaining a single-layer configuration that simplifies manufacturing.
4Ease of manufacture
If conventional coating materials and processes are used, then manufacturing experience is available, but window thickness and manufacturing costs cannot be optimized
Solution Approach 1:
The patent changes the material parameters by using nanoscale silica particles (porous silica and fumed silica) combined with fluorinated compounds. This material parameter change enables achieving comprehensive protective functions in a single, thinner coating layer, reducing overall window thickness while maintaining or improving protective performance.
