Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If antenna units are manually selected by users based on subjective experience, then the system allows user control, but the transmission efficiency is suboptimal because objective network quality indicators are not considered
Solution Approach 1:
The antenna selection function is transferred from manual user operation to automatic system operation. The control device automatically tests each antenna unit, generates quality indicators, and selects the optimal antenna without requiring user intervention, thereby achieving both ease of operation and optimal transmission efficiency
Solution Approach 2:
The system implements a feedback mechanism where the control device tests antenna units, generates quality indicators based on received signal strength, and uses this feedback information to automatically select the optimal antenna. This closed-loop feedback system ensures transmission efficiency is maximized based on objective network quality indicators
2Device complexity
If antenna units are restricted to fixed groups for operation, then the system structure is simplified, but the flexibility of matching between antenna units is limited, adversely influencing system performance
Solution Approach 1:
The system transitions from static fixed antenna groups to dynamic antenna selection. The control device can test and select any antenna unit from the available pool based on real-time signal quality, allowing the system to adapt to changing environmental conditions and optimize performance without being constrained by predetermined group configurations
Solution Approach 2:
The antenna system is divided into independently testable and selectable units. Each antenna unit can be individually tested and evaluated, allowing the control device to select the optimal combination of antenna units rather than being limited to fixed groups, thereby increasing flexibility while maintaining manageable system complexity
3Stability of the object's composition
If multiple antenna groups operate separately with fixed configurations, then the system maintains stable operation, but the ability to flexibly adjust and form different antenna groups is restricted
Solution Approach 1:
The system automatically performs antenna testing and selection without requiring manual reconfiguration. The control device independently tests each antenna unit and determines the optimal configuration, maintaining stable operation through automated decision-making while enabling flexible adaptation to different operational conditions
Solution Approach 2:
The control device performs preliminary testing of all antenna units before actual data transmission. By pre-evaluating each antenna unit's signal quality and generating quality indicators, the system establishes an optimal antenna configuration in advance, ensuring both stable operation during data transmission and the flexibility to adapt to changing conditions through periodic re-testing

AI summary
A method is adapted for controlling an antenna system that includes multiple antenna groups, each including multiple antenna units. The method includes: controlling each of the antenna units of each of the antenna groups to receive one and the same test signal; generating, for each antenna unit, a quality indicator, which is associated with a signal quality of the test signal, with reference to the test signal received thereat; and selecting, for each antenna group, one of the antenna units, the quality indicator corresponding to which indicates an optimum signal quality from among the antenna units of the respective antenna group, to be a working antenna unit of the respective antenna group for performing subsequent data transmission.
