Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used between UAV and autonomous mobile device, then ease of operation is improved, but data transmission bandwidth is limited
Solution Approach 1:
The patent introduces a transmission line as an intermediary component that physically connects the UAV to the autonomous mobile device. This transmission line serves as a mediator that enables high-bandwidth wired communication between the two devices, resolving the bandwidth limitation of wireless communication while maintaining ease of operation through automated connection management
2Ease of operation
If UAV uses battery power for autonomous operation, then ease of operation is improved, but power supply duration is limited
Solution Approach 1:
The patent implements continuous power supply to the UAV by drawing electricity through the transmission line from the autonomous mobile device during operation. This eliminates the intermittent recharging cycles required by battery-powered systems, enabling continuous autonomous operation without power supply interruptions
Solution Approach 2:
The transmission line serves dual functions as both a communication medium and a power delivery channel. By using the transmission line as an intermediary for both data and power transmission, the system eliminates the need for separate battery systems while maintaining ease of autonomous operation
3Measurement precision
If computing tasks are performed on UAV, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the computing functions by separating them from the UAV and placing them on the autonomous mobile device. The UAV focuses on sensing and data collection while the mobile device handles complex computing tasks, achieving high measurement precision without increasing UAV complexity
Solution Approach 2:
The transmission line acts as an intermediary that enables the UAV to access powerful computing resources on the mobile device. This allows the system to perform complex image processing and analysis for high-precision checking without requiring the UAV itself to have complex onboard computing capabilities
