Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user terminal uses conventional main antenna and diversity antenna configuration, then the device complexity is kept simple, but the reception performance cannot be greatly enhanced in very weak electric field regions
Solution Approach 1:
The patent implements dynamic antenna selection by enabling the user terminal to switch between different antenna configurations (2-antenna mode and 4-antenna mode) based on real-time signal quality assessment. The terminal evaluates signal strength and quality parameters, then adaptively selects the appropriate antenna set, transforming the static antenna system into a dynamic one that adjusts to varying communication environments.
Solution Approach 2:
The patent changes the operational parameters of the antenna system by switching between different antenna configurations. When signal quality is poor, the system activates all four antennas (two main antennas and two diversity antennas) to improve reception. When signal quality is good, it reduces to two antennas to save power. This parameter change approach allows the system to optimize reception performance based on actual signal conditions.
2Reliability
If the user terminal uses all antennas for signal reception, then the reception performance is improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic power management by enabling the user terminal to switch between different antenna configurations (2-antenna mode and 4-antenna mode) based on real-time signal quality assessment. The terminal evaluates signal strength and quality parameters, then adaptively selects the appropriate antenna set, transforming the static antenna system into a dynamic one that adjusts to varying communication environments.

3Adaptability or versatility
If the user terminal uses conventional antenna schemes, then the device operates in all communication environments, but it does not efficiently correspond to network environment changes in reception performance or power consumption
Solution Approach 1:
The patent implements feedback-based antenna selection by continuously monitoring signal quality parameters and using this information to make informed decisions about antenna configuration. The terminal assesses the current communication environment, provides feedback to the antenna selection mechanism, and adjusts the antenna configuration accordingly. This closed-loop feedback system enables efficient adaptation to varying network conditions.
