Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a single conductive layer is used in the electrode, then the device structure is simple, but the resistance value is high and response speed is slow
Solution Approach 1:
The electrode uses a composite structure with multiple conductive layers (e.g., ITO layer and metal mesh layer) with different resistance values stacked together. This composite structure reduces the overall resistance value while maintaining structural integrity, enabling faster response speed without excessive complexity.
Solution Approach 2:
The patent changes the resistance parameter of the electrode by combining layers with different resistance characteristics. The first conductive layer has a first resistance value and the second conductive layer has a second resistance value, creating a composite electrode with optimized overall resistance for improved response speed.
2Adaptability or versatility
If existing smart glass technology is used, then the structure is simple, but partial adjustment capability is lost
Solution Approach 1:
The electrode is divided into multiple independent conductive layers that can be controlled independently. This segmentation allows different regions or layers to be adjusted separately, enabling partial adjustment capability where only certain areas of the smart glass need to change their optical properties.
Solution Approach 2:
The patent implements dynamic control capability by enabling independent adjustment of different conductive layers. This allows the system to adapt to different scenarios dynamically, providing partial adjustment functionality where the degree and location of optical property changes can be customized in real-time.
