Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam tracking is performed by sequentially operating possible beam combinations, then beam search and tracking can locate Tx/Rx electronic devices, but communication stability deteriorates and power consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing multiple antenna pairs before communication begins. The electronic device pre-configures several antenna pairs (e.g., first antenna element with first/second antenna elements, second antenna element with third/fourth antenna elements) so that when communication starts, the device can immediately use these pre-established pairs without performing sequential beam searching, thereby reducing power consumption while maintaining communication stability
Solution Approach 2:
The patent implements dynamics by enabling the electronic device to dynamically switch between multiple pre-established antenna pairs based on communication conditions. When the location of Tx/Rx devices changes, the system can flexibly select from available antenna pairs rather than reperforming sequential beam tracking, thus adapting to changing conditions while avoiding repetitive operations that consume power

3Adaptability or versatility
If multiple array antennas are disposed in the electronic device for mmWave band communication, then 5G data communication capability is enabled, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the antenna system into multiple independent antenna elements (first antenna element, second antenna element, third antenna element, fourth antenna element) that can be independently controlled and configured. Each antenna element can form pairs with others, allowing the system to support 5G mmWave communication while managing complexity through modular, segmented architecture
Solution Approach 2:
The patent implements universality by designing antenna pairs that can serve multiple communication functions. The same set of antenna elements can form different pairs (first with first/second, second with third/fourth) to adapt to various communication scenarios, locations, and conditions, enabling versatile 5G communication without proportionally increasing overall system complexity
