Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate antenna device is installed in the mobile communication terminal, then wireless communication function is enabled, but the size of the terminal increases and mounting space is consumed
Solution Approach 1:
The patent merges the antenna function with the display structure by using the conductive layer of the display as the antenna radiator. This integration eliminates the need for a separate antenna device, thereby maintaining wireless communication capability while reducing terminal volume and eliminating dedicated mounting spaces.
Solution Approach 2:
The conductive layer of the display serves dual purposes: it functions as both the display structure and the antenna radiator. This multi-functionality allows the same component to fulfill multiple roles, reducing the overall number of components and terminal size.
2Reliability
If a separate antenna device is installed in the mobile communication terminal, then wireless communication function is enabled, but the mounting space and active area are consumed
Solution Approach 1:
The antenna function is merged with the display structure, allowing the conductive layer to serve as both the display component and the antenna radiator. This eliminates the need for separate mounting spaces and active areas dedicated to antenna installation.
Solution Approach 2:
The display's conductive layer performs multiple functions simultaneously - it acts as the display structure and as the antenna radiator. This multi-functionality eliminates the need for dedicated mounting spaces, as the antenna shares the same space as the display.
3Volume of moving object
If the area for mounting the antenna is reduced, then miniaturization is achieved, but antenna radiation performance deteriorates
Solution Approach 1:
