Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication resources are allocated without considering battery capacity, then communication service quality is maintained, but battery depletion occurs leading to crashes
Solution Approach 1:
The patent implements dynamic adjustment of communication resource allocation based on real-time battery capacity monitoring. The control device continuously monitors battery status and adapts communication resource allocation thresholds accordingly, transitioning from static to dynamic resource management to prevent battery depletion while maintaining service quality
Solution Approach 2:
The patent changes the parameter of communication resource allocation by adjusting allocation thresholds based on battery capacity levels. When battery capacity decreases, the control device reduces communication resource allocation thresholds, thereby controlling power consumption to maintain flight stability while preserving essential communication services
2Productivity
If communication resource allocation is increased, then service quality improves, but power consumption increases depleting battery capacity
Solution Approach 1:
The patent dynamically changes communication resource allocation parameters based on battery capacity. The control device adjusts allocation thresholds to optimize the balance between service quality and power consumption, ensuring that communication resources are allocated efficiently according to available energy levels
Solution Approach 2:
The patent implements a feedback mechanism where the control device monitors battery capacity status and uses this information to adjust communication resource allocation. This closed-loop control ensures that power consumption remains within safe limits while maintaining acceptable service quality
3Reliability
If battery capacity is monitored and resource allocation is adjusted, then flight stability is maintained, but system complexity increases
Solution Approach 1:
The control device performs multiple functions including battery capacity monitoring, communication resource allocation management, and flight stability control within a single integrated system. This multi-functionality reduces the need for separate dedicated systems, thereby limiting the increase in overall system complexity
