Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple receiving circuits are configured for different bands, then the system can receive non-continuous band signals, but the receiving circuits enter idle mode when only one segment is transmitted, reducing system efficiency
Solution Approach 1:
The receiving circuits are designed to perform multiple functions: they can receive signals in their designated bands (first band for first receiving circuit, second band for second receiving circuit) and also receive signals in alternative bands when needed. The controller dynamically assigns circuits to appropriate bands based on transmission patterns, ensuring all circuits remain productive whether receiving continuous or non-continuous band signals.
Solution Approach 2:
The system implements dynamic band assignment where the controller monitors transmission patterns and reconfigures which receiving circuit operates in which band in real-time. When signals are transmitted only in the first band, the second receiving circuit is dynamically switched from its designated second band to receive in the first band instead, preventing idle modes and maintaining high system efficiency.
2Reliability
If receiving circuits are dedicated to specific bands, then signal reception is optimized, but circuit utilization is reduced when only one band is active
Solution Approach 1:
Each receiving circuit is designed with universal capability to receive signals from multiple bands. The first receiving circuit can receive from both the first band and the second band, and the second receiving circuit can receive from both the second band and the first band. This multi-functionality ensures that signal reception remains optimized while circuit utilization is maximized based on actual transmission needs.
Solution Approach 2:
The system changes the operating parameters of receiving circuits dynamically. When the transmission pattern changes from non-continuous to continuous band signaling, the controller adjusts which circuit operates in which band, effectively changing the frequency parameters of circuit operation to match current transmission requirements, thereby maintaining both reception quality and utilization efficiency.
3Device complexity
If the system uses fixed band assignment for receiving circuits, then configuration is simple, but flexibility in handling different transmission modes is reduced
Solution Approach 1:
The system transitions from static to dynamic configuration. While the basic circuit setup remains simple (first receiving circuit, second receiving circuit, controller), the system dynamically adapts its operation mode based on transmission patterns. The controller monitors whether signals are transmitted in continuous or non-continuous bands and automatically reconfigures circuit assignments accordingly, providing flexibility without significantly increasing physical complexity.
Solution Approach 2:
The system implements self-service through automatic detection and reconfiguration. The controller automatically detects the transmission mode (continuous or non-continuous bands) and self-adjusts the band assignment for receiving circuits without requiring manual reconfiguration. This maintains configuration simplicity while achieving high adaptability to different transmission modes.
