Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle-mounted equipment and road facilities are used to improve safety recognition, then dangerous situations can be detected, but the system becomes expensive and difficult to commercialize
Solution Approach 1:
The patent introduces an unmanned aerial vehicle (UAV) as an intermediary component between the vehicle and the communication infrastructure. The UAV carries communication equipment and positions itself strategically to provide signal coverage in shadow areas, thereby improving safety recognition without requiring expensive modifications to the vehicle itself or road facilities.
Solution Approach 2:
The patent employs a UAV that can be deployed temporarily for specific tasks rather than permanent expensive infrastructure. The UAV serves as a cost-effective, mobile communication node that can be positioned as needed to address shadow area problems, replacing the need for costly fixed installations.
2Reliability
If communication equipment is installed in shadow areas, then communication sensitivity improves, but the system complexity increases
Solution Approach 1:
The patent makes the communication system dynamic by using a movable UAV instead of fixed infrastructure. The UAV can adjust its position, altitude, and orientation in real-time to optimize communication coverage in shadow areas, providing adaptability without permanent complex installations.
Solution Approach 2:
The UAV serves multiple functions: it acts as a communication relay, performs environmental sensing, and provides navigational support. This multi-functionality reduces the need for separate specialized equipment, thereby improving communication sensitivity without proportionally increasing system complexity.
3Measurement precision
If the UAV measures communication sensitivity at multiple altitudes, then optimal path determination improves, but the time required for measurement increases
Solution Approach 1:
The patent performs communication sensitivity measurements at multiple altitudes in advance, before the vehicle reaches the shadow area. This preliminary action allows the system to pre-determine the optimal flight path and communication strategy, ensuring accurate measurements without delaying the vehicle's journey.
Solution Approach 2:
The UAV conducts measurements at periodic altitude intervals rather than continuously, sampling communication sensitivity at discrete height levels. This periodic approach provides sufficient measurement precision for path optimization while significantly reducing the total measurement time compared to continuous monitoring.
