Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the antenna switch is allocated to operate simply as primary cell antenna and secondary cell antenna as first designated, then the device complexity is reduced and ease of operation is improved, but the adaptability to changing network environments deteriorates and data processing speed cannot be enhanced
Solution Approach 1:
The antenna switch operation is changed from static (fixed allocation) to dynamic (adaptive switching). The processor continuously monitors data throughput speeds and dynamically reconfigures the antenna switch connection between first and second grounding units based on real-time network conditions, enabling the system to adapt to changing environments while maintaining operational simplicity through automated control.
Solution Approach 2:
The system changes the operational parameters of the antenna switch by alternating between different grounding unit connections. When the first data throughput speed exceeds the second, the switch connects to the first grounding unit; when the second exceeds the first, it connects to the second grounding unit. This parameter switching enables adaptability without increasing operational complexity for the user.
2Device complexity
If the antenna switch is allocated to operate simply as primary cell antenna and secondary cell antenna as first designated, then the device complexity is reduced, but the productivity in terms of data processing speed deteriorates under varying network conditions
Solution Approach 1:
The antenna switch system performs self-optimization through automated throughput monitoring and adaptive reconfiguration. The processor automatically detects when data throughput speeds change and independently controls the antenna switch to connect to the appropriate grounding unit without requiring user intervention or complex manual configuration, thereby maintaining low device complexity while maximizing productivity.
Solution Approach 2:
The system implements a feedback loop where the processor continuously monitors data throughput speeds through carrier aggregation and uses this feedback to dynamically adjust the antenna switch configuration. This closed-loop control enables the system to automatically optimize data processing speed based on real-time network conditions without increasing operational complexity.
3Productivity
If carrier aggregation is performed by simultaneously using at least two different frequency bands, then the productivity in terms of data transmission amount is increased, but the device complexity increases due to multi-band antenna requirements
Solution Approach 1:
The antenna system is designed with multi-functionality to support both single-band and carrier aggregation modes. The same antenna structure with switchable grounding units can operate in different frequency bands and different aggregation configurations, eliminating the need for separate dedicated antennas for each band and reducing overall device complexity while maintaining high data transmission capability.
