Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple millimeter-wave antenna modules are fixed in different positions of the CPE to improve alignment with base stations, then the alignment accuracy and omnidirectional coverage are improved, but the device cost and complexity increase
Solution Approach 1:
The patent merges the functions of multiple fixed antenna modules into a single rotatable millimeter-wave antenna. By combining the radiation functions of multiple antennas into one movable antenna, the system achieves omnidirectional coverage through rotation while reducing device complexity and cost associated with multiple simultaneous antenna modules.
Solution Approach 2:
The patent transforms the static configuration of multiple fixed antenna modules into a dynamic single rotatable antenna system. The millimeter-wave antenna can rotate to different orientations to achieve alignment with base stations from various directions, providing the same omnidirectional coverage functionality as multiple fixed antennas but with reduced complexity.
2Adaptability or versatility
If multiple millimeter-wave antenna modules are deployed to achieve omnidirectional coverage, then the coverage capability is improved, but the cost increases
Solution Approach 1:
The patent combines multiple antenna functions into a single rotatable antenna unit. This merged design achieves omnidirectional coverage by rotating the single antenna to different positions, eliminating the need for multiple simultaneous antenna modules and thereby reducing device complexity while maintaining versatility.
Solution Approach 2:
The single rotatable millimeter-wave antenna is designed to perform multiple functions that would otherwise require separate antenna modules. By rotating to different orientations, the same antenna can serve multiple directional coverage needs, making it a universal solution that replaces multiple specialized fixed antennas.
3Measurement precision
If adjacent stepping rotations are performed to scan multiple blocks for network information, then the alignment accuracy is improved, but signal interference between rotations increases
Solution Approach 1:
The patent applies preliminary action by performing a coarse interval scan across multiple blocks before conducting fine-grained alignment in the target block. This two-stage approach allows the system to first identify the general direction of the base station with minimal interference, then perform precise alignment in the identified target block, thereby reducing overall signal interference while maintaining alignment accuracy.
Solution Approach 2:
The patent segments the scanning process into two distinct phases: interval scanning across multiple blocks to identify the target block, and then fine scanning within the target block to achieve precise alignment. This segmentation allows the system to perform coarse localization with larger steps (less interference) followed by fine tuning in the identified region, reducing cumulative signal interference while achieving high alignment accuracy.
