Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas and duplexers are added to support 4G and 5G dual connection, then communication capability is improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by designing the additional antenna to receive diversity reception signals for both 4G and 5G frequency bands simultaneously. The additional filter is configured to filter diversity reception signals across multiple frequency bands, allowing a single antenna and filter combination to serve multiple communication functions rather than requiring separate dedicated components for each frequency band.
Solution Approach 2:
The patent merges the diversity reception functionality for 4G and 5G into a shared antenna system. The additional antenna is connected to the radio frequency transceiver module and handles diversity signals for both 4G (first frequency band) and 5G (second frequency band) through the additional filter, combining what would traditionally require separate antenna paths into a unified structure.
2Reliability
If additional filters and amplifiers are added to ensure signal insulation and amplification, then signal quality is improved, but device complexity increases
Solution Approach 1:
The additional filter is designed as a multi-functional component that filters diversity reception signals for both 4G and 5G frequency bands simultaneously. This single filter handles multiple frequency bands rather than requiring separate filters for each band, maintaining signal quality while reducing the total number of filtering components needed.
3Device complexity
If a shared antenna is used for diversity reception in multiple frequency bands, then device complexity is reduced, but signal insulation difficulty increases
Solution Approach 1:
The additional filter acts as an intermediary component between the shared additional antenna and the radio frequency transceiver module. It mediates the signal paths for different frequency bands, filtering and separating 4G and 5G diversity reception signals at the appropriate stage, thereby solving the signal insulation challenge while maintaining the simplicity of the shared antenna structure.
