Engineering Contradiction Analysis
1Reliability
If multiple independent communication circuits for different frequency bands are provided, then communication reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple communication circuits for different frequency bands (first communication circuit for higher band, second communication circuit for lower band) into a unified communication device with shared control circuitry. This merging approach maintains the ability to perform multiple frequency band communications while reducing overall device complexity and manufacturing cost compared to providing completely independent circuits for each band.
Solution Approach 2:
The control circuitry is designed with multi-functionality to manage both first and second communication circuits across different frequency bands. This universal control mechanism allows a single control unit to handle multiple communication functions, thereby improving reliability through diverse frequency band support while avoiding the complexity of separate dedicated control circuits for each frequency band.
2Reliability
If multiple independent communication circuits for different frequency bands are provided, then communication reliability is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges multiple communication circuits into a single integrated communication device with shared components and control logic. This consolidation reduces the total number of discrete parts that need to be manufactured and assembled, thereby lowering manufacturing costs while preserving the reliability benefits of multi-frequency band communication capability.
3Adaptability or versatility
If frequency band switching is implemented, then adaptability to different communication conditions is improved, but control complexity increases
Solution Approach 1:
The control circuitry is designed as a universal controller capable of managing multiple frequency bands and switching between them based on communication conditions. This multi-functional control approach enables frequency band adaptability without requiring separate control mechanisms for each band, thereby maintaining simplicity while achieving versatility.
Solution Approach 2:
The communication device implements dynamic frequency band switching where the control circuitry can adaptively select between first and second communication circuits based on real-time communication conditions. This dynamic approach provides flexibility and adaptability while using a unified control structure rather than static, dedicated controls for each frequency scenario.
