Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an intelligent reflecting surface is integrated onto a display screen, then wireless communication performance is improved, but the visual transparency and aesthetic design are compromised
Solution Approach 1:
The display screen is divided into multiple functional layers including a substrate, functional layer with reflecting units, and shielding layer. The reflecting units are segmented and distributed across the functional layer, allowing selective reflection of wireless signals while maintaining overall visual transparency of the display screen.
Solution Approach 2:
Different regions of the display screen have different properties: the functional layer contains reflecting units with specific electromagnetic properties for wireless signal reflection, while the overall structure maintains optical transparency. The modulation circuit locally adjusts the amplitude and phase of electrical signals on individual reflecting units to achieve desired communication performance without affecting global transparency.
2Reliability
If a modulation circuit is integrated within the substrate, then the distance between the reflecting unit and modulation circuit is reduced improving signal transmission, but the device structure becomes more complex
Solution Approach 1:
The modulation circuit is merged with the substrate to form an integrated structure. The substrate serves dual functions as both the structural support for the display screen and the mounting platform for the modulation circuit, eliminating the need for separate external modulation circuits and reducing overall device complexity.
Solution Approach 2:
The substrate is designed to perform multiple functions: it provides mechanical support for the display structure, serves as the mounting base for the modulation circuit, and facilitates electrical connections between the modulation circuit and reflecting units. This multi-functionality reduces the number of separate components needed.
3Reliability
If the shielding layer is provided on the functional layer, then the reflection effect of the reflecting unit is improved, but the impact of wireless signal transmission into the display screen increases
Solution Approach 1:
The shielding layer, which could potentially block wireless signals, is strategically positioned and designed to reflect signals back toward the reflecting units rather than allowing them to penetrate deep into the display screen. This converts the potential harmful effect of signal transmission into a beneficial reflection effect that enhances wireless communication performance.
Solution Approach 2:
The shielding layer acts as an intermediary between the functional layer with reflecting units and the substrate. It mediates the interaction of wireless signals by providing a controlled reflection interface that enhances the overall reflection effect while preventing excessive signal penetration into the internal structure of the display screen.
