Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the antenna is positioned close to the display, then the device size is reduced, but the antenna performance deteriorates
Solution Approach 1:
The patent merges the antenna structure with the display structure by making the display frame itself serve as the antenna radiator. The conductive frame of the display is electrically connected to the wireless communication circuit, eliminating the need for a separate antenna component while maintaining compact device dimensions and ensuring adequate antenna performance through proper electrical connection and grounding.
2Reliability
If a separate space is provided for the antenna, then the antenna performance is maintained, but the device complexity increases
Solution Approach 1:
The display frame structure is designed to serve dual functions: as the structural support for the display and as the radiating element for wireless communication. This multi-functional design eliminates the need for separate antenna components and reduces overall device complexity while maintaining both display functionality and wireless communication capability.
3Device complexity
If additional configurations like transparent electrode layers are installed on the display, then the antenna can be integrated, but the manufacturing cost increases
Solution Approach 1:
The display frame structure is designed to inherently serve as the antenna radiator without requiring additional transparent electrode layers or other supplementary configurations. The frame's own conductive properties are utilized, and through proper electrical connection and grounding design, the structure performs both its structural and antenna functions, thereby avoiding additional manufacturing steps and costs.
4Device complexity
If additional configurations are installed on the display, then the antenna integration is achieved, but the display visibility is reduced
Solution Approach 1:
The antenna function is extracted from the display area and implemented using the surrounding frame structure instead. This extraction approach allows the display area to remain clear and unobstructed, maintaining full visibility and aesthetic appearance, while the frame structure independently provides the antenna functionality through its conductive properties and electrical connection to the wireless communication circuit.
