Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the aircraft uses a vision auxiliary apparatus to obtain flight environment information, then the aircraft can implement precise hovering and intelligent landing and obstacle avoidance, but in low-light environments the vision positioning cannot be effectively performed
Solution Approach 1:
The patent introduces a light emitting apparatus as an intermediary device to illuminate the flight environment. This mediator provides additional light to the scene being observed by the vision system, enabling effective vision positioning in low-light conditions without directly modifying the vision apparatus itself
Solution Approach 2:
The patent changes the lighting parameters of the flight environment by controlling the light emitting apparatus to emit light with specific intensity and duration. This parameter change transforms the ambient luminance from insufficient to adequate levels, enabling the vision system to function properly
2Use of energy by moving object
If the aircraft operates in low-light environments without additional lighting, then energy consumption is reduced, but the vision system cannot run normally and the aircraft cannot learn the flight environment
Solution Approach 1:
The patent implements dynamic control of the light emitting apparatus based on real-time assessment of ambient luminance and vision system performance. The lighting is activated only when needed (when ambient light is insufficient), and adjusted in intensity and duration to provide minimum necessary illumination, optimizing the balance between energy consumption and vision system reliability
Solution Approach 2:
The patent employs feedback mechanisms where the vision system's performance is continuously monitored, and this information feeds back to control the light emitting apparatus. When the vision system detects insufficient lighting conditions, it triggers the light emitting apparatus to provide additional illumination, creating a closed-loop control system that adapts to environmental conditions
