Engineering Contradiction Analysis
1Volume of moving object
If Sub-6G antenna and millimeter wave antenna are placed close to each other, then space occupancy is reduced, but transmission performance is degraded due to mutual interference
Solution Approach 1:
The patent applies dimensionality change by transitioning from planar antenna arrangement to three-dimensional spatial arrangement. The millimeter wave antenna is positioned on the rear cover while Sub-6G antennas are located on the main board, creating vertical separation. This spatial dimensionality change allows both antenna types to be placed close in the XY plane (reducing footprint) while maintaining adequate distance in the Z direction (preventing interference).
Solution Approach 2:
The patent implements nesting by integrating multiple antenna systems within a compact hierarchical structure. The millimeter wave antenna group is nested on the rear cover, which itself is part of the overall device assembly containing the main board with Sub-6G antennas. This nested arrangement allows efficient space utilization while maintaining functional separation between different antenna frequency bands.
2Reliability
If Sub-6G antenna and millimeter wave antenna are set far away from each other, then transmission performance is maintained, but space occupied by them increases
Solution Approach 1:
The patent utilizes vertical dimensionality to achieve spatial separation without increasing horizontal footprint. By placing the millimeter wave antenna on the rear cover (elevated plane) and Sub-6G antennas on the main board (lower plane), the design maintains adequate separation distance for signal integrity while keeping the device's width and depth compact.
Solution Approach 2:
The patent segments the antenna system into distinct functional groups positioned in different spatial zones. The millimeter wave antenna group is segregated on the rear cover, while Sub-6G antennas are separated on the main board. This segmentation allows each antenna type to operate independently with optimized performance while sharing the overall device space efficiently.
