Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lighting system uses fixed spectral output, then the device complexity is reduced, but the adaptability to different lighting conditions and desired effects is limited
Solution Approach 1:
The lighting system dynamically adjusts spectral output by transitioning between different spectral weighting modes (first, second, third modes) that optimize different variables (chromacity coordinates, color brightness temperature, color brightness) based on desired effects, making the system adaptive to different lighting conditions while managing complexity through controlled dynamic adjustment
Solution Approach 2:
The system changes spectral parameters by optimizing different predetermined variables within different predetermined domains corresponding to different spectral weighting modes, allowing adaptation to various lighting conditions and desired effects without requiring complete system redesign
2Reliability
If the lighting system optimizes for peak wakefulness, then the lighting effectiveness for alertness is improved, but the power consumption increases
Solution Approach 1:
The system optimizes specific spectral parameters (chromacity coordinates, color brightness temperature) within predetermined domains to achieve desired effects like peak wakefulness, adjusting parameters dynamically to balance effectiveness with power consumption constraints in aircraft lighting
3Adaptability or versatility
If the lighting system transitions between multiple spectral weighting modes, then the versatility of lighting effects is improved, but the control complexity increases
Solution Approach 1:
The controller dynamically transitions between multiple spectral weighting modes (first, second, third modes) that correspond to different predetermined domains (chromacity coordinates, color brightness temperature, color brightness), enabling versatile lighting effects while managing control complexity through structured mode transitions
Solution Approach 2:
The lighting system achieves multi-functionality by implementing multiple spectral weighting modes that can be activated based on different desired effects, allowing a single system to provide diverse lighting functions (mood creation, wakefulness enhancement, ambient lighting) without requiring separate dedicated systems
