Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional parabolic antenna or lens antenna is used, then the antenna can concentrate radio frequency energy to deliver signals to distant terminal devices, but the antenna cannot flexibly adjust the amplitude or phase of the radio frequency signal
Solution Approach 1:
The antenna device is segmented into a phased array antenna with multiple antenna units and a wave-shaping accessory. Each antenna unit can independently adjust its amplitude and phase, enabling flexible beam shaping while maintaining a relatively simple overall structure. The segmentation allows independent control of signal parameters without requiring complex mechanical adjustments to the entire antenna system.
Solution Approach 2:
The antenna device incorporates dynamic control capabilities through a controller that can real-time adjust the amplitude and phase of each antenna unit based on feedback information. This dynamic adjustment enables the antenna to adaptively shape beams for different communication scenarios, transforming a static traditional antenna into a dynamically controllable system without requiring complex mechanical reconfiguration.
2Adaptability or versatility
If a phased array antenna with multiple antenna units is used to achieve beam shaping, then the antenna can flexibly adjust amplitude and phase, but the power consumption increases
Solution Approach 1:
The controller can selectively activate only the necessary number of antenna units required for current communication needs rather than operating all antenna units at full capacity. This partial action approach maintains beam shaping capability while reducing overall power consumption, especially in scenarios where full array activation is not necessary for achieving the desired signal quality.
Solution Approach 2:
The antenna device incorporates a receiver that provides feedback information about signal quality and communication conditions to the controller. The controller uses this feedback to dynamically adjust the operation of antenna units, activating or deactivating units based on real-time needs. This feedback mechanism enables the system to maintain effective beam shaping while minimizing power consumption by operating only the necessary antenna units at appropriate power levels.
