Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional antenna geometries are used, then the antenna can be manufactured with simple processes, but the operating characteristics are narrowly defined
Solution Approach 1:
The patent applies the dynamics principle by making the antenna geometry changeable through control signals. The antenna transitions from a static conventional design to a dynamic configurable structure where elements can be selectively activated or deactivated based on desired operating characteristics, allowing the same physical antenna to adapt to different frequency ranges, polarizations, and radiation patterns.
Solution Approach 2:
The patent implements universality by designing a single antenna structure that can perform multiple functions across different operating conditions. By incorporating control mechanisms that enable selective activation of antenna elements, one antenna replaces multiple conventional antennas, achieving multi-functionality in terms of frequency operation, polarization, and beam direction.
2Adaptability or versatility
If the antenna geometry is fixed, then the design constraints are easier to meet, but the transmission and reception capabilities are narrow
Solution Approach 1:
The patent applies segmentation by dividing the antenna into multiple independent or semi-independent elements that can be controlled individually or in groups. This segmentation allows selective activation of specific elements based on the required operating mode, enabling the antenna to adapt to different use cases while maintaining a manageable manufacturing process for each element.
Solution Approach 2:
The patent implements parameter changes by modifying the electrical and physical characteristics of the antenna through control signals. By changing parameters such as element activation states, feeding configurations, and impedance matching, the antenna achieves different operating characteristics without requiring physical redesign or remanufacturing.
3Adaptability or versatility
If multiple conventional antennas are used to cover different use cases, then the operating capabilities are broader, but the device complexity increases
Solution Approach 1:
The patent applies merging by integrating multiple antenna functions into a single unified structure. Instead of using separate conventional antennas for different frequency ranges, polarizations, or directions, the configurable antenna combines these functions by selectively activating different elements or configurations within one antenna system, thereby reducing overall device complexity.
Solution Approach 2:
The patent implements universality by designing a single antenna system that can perform the functions of multiple conventional antennas. Through control mechanisms that enable reconfiguration of antenna elements, one universal antenna replaces several specialized antennas, achieving broader communication capabilities while simplifying the overall device architecture.
