Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery capacity is increased to extend flight range, then airborne time is improved, but take-off weight increases
Solution Approach 1:
The patent divides the energy supply system into two segments: a compact onboard battery for immediate power needs and a ground-based wireless charging docking station for energy replenishment. This segmentation allows the UAV to maintain lightweight design while achieving extended operational duration through periodic charging stops.
Solution Approach 2:
The wireless charging docking station serves as an intermediary energy transfer medium between the ground power source and the UAV. This mediator enables energy transfer without physical battery attachment or weight increase on the UAV, resolving the contradiction between extended airborne time and weight constraints.
2Productivity
If multiple UAVs charge simultaneously at one docking station, then charging efficiency is improved, but power distribution complexity increases
Solution Approach 1:
The patent implements dynamic power distribution where the docking station automatically adjusts power allocation based on real-time charging status, battery levels, and queue priority of multiple UAVs. This dynamic control enables simultaneous charging of multiple devices while managing power distribution complexity through adaptive algorithms.
Solution Approach 2:
The system employs feedback mechanisms where each UAV's charging status is continuously monitored and reported to the docking station controller. This feedback loop enables intelligent power distribution decisions, allowing multiple UAVs to charge simultaneously while the system automatically manages power allocation to prevent overload and optimize charging efficiency.
