Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed antenna design is used, then device complexity is reduced, but adaptability to environmental changes deteriorates
Solution Approach 1:
The patent implements dynamic antenna configuration by enabling the antenna system to switch between different radiation patterns based on environmental conditions. The processor dynamically selects and activates specific antenna groups from multiple available groups, allowing the system to adapt its radiation characteristics in real-time to changing signal environments, thereby resolving the contradiction between fixed design simplicity and environmental adaptability
Solution Approach 2:
The patent creates a multi-functional antenna system where a single antenna array can perform multiple functions by activating different antenna groups. The system can generate various radiation patterns (e.g., omnidirectional, directional, sector patterns) using the same physical antenna structure, controlled by the processor selecting which antenna groups to activate. This universal design provides environmental adaptability without proportionally increasing overall system complexity
2Adaptability or versatility
If multiple antenna groups are used to adapt to environmental changes, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent divides the antenna system into multiple separable antenna groups, where each group can be independently activated or deactivated. This segmentation allows the processor to selectively enable only the necessary antenna groups based on current environmental conditions, rather than requiring all antennas to operate simultaneously. The segmentation approach enables adaptability while managing complexity through modular, independent units
Solution Approach 2:
The system employs dynamic configuration where the processor continuously monitors environmental conditions and adjusts which antenna groups are active. This dynamic switching capability allows the system to optimize its complexity level in real-time, activating additional antenna groups only when environmental changes require enhanced adaptability, rather than maintaining maximum complexity constantly
3Reliability
If fixed radiation pattern is used, then manufacturing precision requirements are reduced, but transmission performance deteriorates under environmental changes
Solution Approach 1:
The patent implements dynamic radiation pattern selection where the processor monitors environmental conditions and switches between pre-configured radiation patterns to maintain optimal transmission performance. Rather than relying on a single fixed pattern requiring extreme manufacturing precision, the system uses multiple patterns with slightly varied characteristics, selecting the most appropriate one for current conditions. This dynamic approach compensates for manufacturing variations and environmental changes
Solution Approach 2:
The system changes operational parameters by switching between different radiation patterns with varying beam directions, widths, and coverage areas. The processor selects patterns based on environmental conditions such as signal strength, interference levels, and spatial distribution of signal sources. This parameter changes approach allows the system to maintain reliable transmission performance across diverse environments without requiring each individual pattern to achieve peak performance

AI summary
An antenna device includes antennas to receive and transmit signals; and a processor to divide radiation patterns of combinations of the antennas into a predetermined number of characteristic patterns, and to calculate similarities of the characteristic patterns and a RSSI of each of the characteristic patterns. When the antenna device is in operation, the processor reads and analyzes RSSI of the signals received by the antennas, compares the RSSI of the signals of the antennas with the RSSI of the characteristic patterns, and determines a matched characteristic pattern group according to results of comparisons and the similarities of the characteristic patterns.
