Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a chip antenna is used on the PCB, then the device structure is compact, but the antenna efficiency and bandwidth are poor
Solution Approach 1:
The patent extracts the antenna function from the traditional PCB chip antenna configuration and relocates it to the camera ring structure. This extraction allows the antenna to operate in air medium rather than being constrained by the high dielectric constant PCB substrate, thereby improving antenna efficiency and bandwidth while maintaining compact device structure.
Solution Approach 2:
The camera ring is designed to serve dual functions: as a structural component housing the camera lens and as an antenna element for RF signal transmission and reception. This multi-functionality eliminates the need for separate antenna structures, maintaining device compactness while achieving superior antenna performance through the air-filled camera ring cavity.
2Device complexity
If a chip antenna with buried pattern is used, then the antenna is integrated into the PCB, but the bandwidth is limited
Solution Approach 1:
The patent changes the dielectric parameter from high dielectric constant PCB material to air medium by relocating the antenna to the camera ring. This parameter change fundamentally improves the bandwidth characteristic, as air provides a lower dielectric constant and lower loss tangent, enabling wider frequency operation while maintaining integrated design through the camera ring structure.
3Ease of manufacture
If LTCC processing is used for antenna fabrication, then the antenna is integrated into the ceramic substrate, but the manufacturing cost increases
Solution Approach 1:
The camera ring structure serves its primary function of housing the camera lens while simultaneously providing the antenna function. This self-service approach eliminates the need for separate antenna fabrication processes like LTCC, as the camera ring itself becomes the antenna element, thereby reducing manufacturing complexity and cost while maintaining integrated design benefits.
