Engineering Contradiction Analysis
1Length of moving object
If the device is made thinner and more miniaturized, then the thinness and compactness are improved, but the space for mounting electronic modules is reduced
Solution Approach 1:
The patent combines the antenna function with the display structure by integrating the antenna into the display layer itself. The antenna is formed using the same transparent conductive oxide layers that constitute the display electrode, merging two separate functional components (display and communication) into a single integrated structure, thereby eliminating the need for separate antenna mounting space.
Solution Approach 2:
The transparent conductive oxide layer serves multiple functions simultaneously: it acts as both the display electrode material and the antenna element. This multi-functionality allows the same structural component to fulfill both display and wireless communication roles, optimizing the use of limited space in thin-type devices.
2Area of stationary object
If the antenna is integrated into the display layer, then the space for mounting is improved, but the visibility of the antenna from outside increases
Solution Approach 1:
The patent uses transparent conductive oxide materials that are visually transparent or have minimal coloration. By selecting materials with appropriate optical properties, the antenna structure becomes invisible or nearly invisible when viewed from outside the display device, maintaining aesthetic appearance while enabling antenna functionality.
3Adaptability or versatility
If multiple antennas are added for various frequency bands, then the communication capability is improved, but the device complexity increases
Solution Approach 1:
The patent employs a reconfigurable antenna system where the electrical characteristics of the antenna can be dynamically adjusted through control signals. By changing the conductivity or configuration of the transparent conductive oxide layers, a single antenna structure can adapt to operate across multiple frequency bands, replacing the need for multiple fixed-frequency antennas.
