Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the aircraft uses a vision auxiliary apparatus to detect the flight environment, then the aircraft can implement intelligent landing and obstacle avoidance, but in low-light environments the vision positioning cannot be effectively performed
Solution Approach 1:
The control apparatus preliminarily determines whether the ambient luminance satisfies the luminance value required for normal operation of the vision system before executing vision-based flight operations. This preliminary check prevents ineffective vision positioning in low-light conditions by adjusting lighting in advance.
Solution Approach 2:
A light emitting apparatus is introduced as an intermediary to illuminate the flight environment when ambient luminance is insufficient. This mediator enables the vision system to function normally by providing the necessary lighting conditions for effective vision positioning.
2Reliability
If the aircraft operates in low-light environments without additional lighting, then energy consumption is reduced, but the vision system cannot run normally and accurate learning of the flight environment is impaired
Solution Approach 1:
The control apparatus continuously monitors ambient luminance and adjusts the working status of the light emitting apparatus accordingly. When luminance satisfies requirements, lighting is reduced or turned off to save energy; when luminance is insufficient, lighting is activated to ensure vision system operation.
Solution Approach 2:
The working status parameter of the light emitting apparatus is dynamically adjusted based on ambient luminance conditions. The system changes between different operational states (off, dimmed, full brightness) to balance energy consumption with vision system performance requirements.
