Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmission channels are activated to support multiple frequency bands and modes, then the adaptability and communication capability are improved, but the signal consumption increases and operating efficiency decreases
Solution Approach 1:
The radio frequency front-end module is divided into multiple independent transmission channels, each dedicated to specific frequency bands and communication modes. The control unit selectively activates only the channels needed for current communication requirements, rather than keeping all channels active simultaneously. This segmentation allows the system to support multiple frequency bands and modes while minimizing signal consumption by activating only necessary channels.
Solution Approach 2:
The system dynamically adjusts which transmission channels are activated based on real-time communication requirements. The control unit monitors the current frequency band and mode being used, and dynamically switches between different channel configurations. This dynamic activation strategy ensures that only the minimal necessary channels are active at any given time, reducing overall signal consumption while maintaining full adaptability across multiple bands and modes.
2Adaptability or versatility
If multiple transmission channels are activated to support multiple frequency bands and modes, then the adaptability and communication capability are improved, but the operating efficiency decreases
Solution Approach 1:
Transmission channels are segmented into distinct groups based on frequency band and communication mode requirements. Each channel is optimized for specific bands, allowing the control unit to activate only the relevant channels for current operations. This prevents signal routing through unnecessary channels, thereby improving operating efficiency while maintaining support for multiple frequency bands and modes.
Solution Approach 2:
The control unit implements dynamic channel selection that adapts to current communication needs. When switching between different frequency bands or modes, the system rapidly reconfigures which channels are active, avoiding the overhead of maintaining all channels in active state. This dynamic reconfiguration improves operating efficiency by minimizing the number of active channels while preserving full multi-band and multi-mode capability.
3Use of energy by moving object
If a switch unit is added to selectively activate transmission channels, then the signal consumption is reduced, but the device complexity increases
Solution Approach 1:
The switch unit is designed as a multi-functional component that handles multiple frequency bands and communication modes through a single unified structure. Rather than implementing separate switching mechanisms for each band and mode, the universal switch unit can route signals across all channels and modes, reducing overall device complexity while enabling selective channel activation to minimize signal consumption.
Solution Approach 2:
The control unit acts as an intermediary that intelligently manages the switch unit's operation. It receives information about current communication requirements and automatically configures the switch unit to activate only necessary channels. This intermediary control layer simplifies the overall system architecture by centralizing the decision-making logic, reducing the complexity that would otherwise be distributed across multiple independent control mechanisms.
