Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are arranged in limited terminal space, then communication functions are enhanced, but antenna interference increases and performance deteriorates
Solution Approach 1:
The patent divides the antenna system into multiple independent antenna units, each serving specific communication functions. By segmenting the antenna functions and assigning them to separate physical antenna elements, the system reduces mutual interference while maintaining diverse communication capabilities across different frequency bands and modes.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of antennas within the terminal, positioning antenna elements at different locations and orientations. This spatial dimensionality allows multiple antennas to coexist with reduced interference, as signals propagate through different spatial paths and reduce coupling effects.
2Adaptability or versatility
If multiple antennas are arranged in limited terminal space, then communication functions are enhanced, but device complexity increases
Solution Approach 1:
The patent designs antenna units that can serve multiple communication functions simultaneously, such as supporting both transmission and reception, and operating across multiple frequency bands. This multi-functionality reduces the total number of antenna elements needed, thereby simplifying the overall antenna system while maintaining comprehensive communication capabilities.
Solution Approach 2:
The patent combines multiple antenna functions into integrated antenna modules or arrays, where individual antenna elements work together as unified structures. This merging approach reduces the number of separate antenna components and simplifies the overall system architecture while achieving diverse communication functions.
3Device complexity
If filter network and matching circuit are added to integrate antennas, then antenna integration is achieved, but multi-mode multi-pass communication cannot be realized
Solution Approach 1:
The patent employs dynamic switching mechanisms that can reconfigure antenna connections and signal paths based on the required communication mode. This dynamic adaptability allows the same antenna system to support multiple communication modes and passes by dynamically adjusting the signal routing, without requiring separate dedicated antenna sets for each mode.
