Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery capacity is increased to extend flight time and range, then available power is improved, but vehicle weight increases
Solution Approach 1:
The patent combines solar panels with the UAV structure to create a hybrid power system. The solar panels are integrated into the UAV body, allowing simultaneous energy generation and structural functionality, thereby extending flight duration without adding significant weight compared to larger batteries
Solution Approach 2:
The solar panels serve multiple functions: they generate electrical energy to power the UAV, extend flight duration, and can be integrated into the structural design. This multi-functionality addresses the flight time extension need without the weight penalty of purely battery-based solutions
2Duration of action of moving object
If solar panels are added to extend flight time, then power generation capability is improved, but device complexity increases
Solution Approach 1:
The solar panels are merged with the UAV structure rather than being added as separate components. This integration approach reduces overall system complexity by combining energy generation with structural elements, eliminating the need for additional mounting hardware and simplifying the power system architecture
Solution Approach 2:
The solar panels provide self-service by generating power directly from sunlight during flight operations. This autonomous energy generation reduces the complexity of external power supply systems and simplifies the overall power management architecture
3Use of energy by moving object
If conventional charging methods are used without sunlight optimization, then operational simplicity is maintained, but energy efficiency deteriorates
Solution Approach 1:
The charging system dynamically adjusts the UAV flight path to optimize solar panel exposure to sunlight. The system continuously monitors sunlight conditions and modifies navigation parameters in real-time, maximizing energy generation efficiency while maintaining relatively simple operational procedures
Solution Approach 2:
The system incorporates feedback mechanisms that monitor sunlight intensity and battery charge levels, then adjust flight parameters accordingly. This feedback loop optimizes energy harvesting efficiency without requiring complex manual intervention, automatically balancing energy generation with mission objectives
