Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment and fixed projection surfaces are used, then device structure is simple, but flexibility and comfort for passengers are restricted
Solution Approach 1:
The patent implements dynamic adaptability by using sensor units to continuously detect body size and position, allowing the light projection to automatically adjust and adapt to different passengers and seating positions in real-time, transforming a static fixed projection system into a dynamic adaptable one
Solution Approach 2:
The system performs self-adjustment through automated detection and adaptation mechanisms. The sensor units continuously monitor the passenger's body and automatically adjust the light projection parameters without requiring manual intervention, enabling the system to serve itself and adapt to changing conditions
2Ease of operation
If fixed projection surfaces are used, then manufacturing is simple, but operation convenience is reduced
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated optical-detection system. Instead of mechanically moving the light source or adjusting fixed surfaces, the system uses sensor units to detect body position and automatically adjusts the light projection through electronic control, substituting mechanical operations with automated sensing and adjustment
3Adaptability or versatility
If mechanical adjustment is provided, then structure is simple, but continuous adaption to body position is not achieved
Solution Approach 1:
The patent implements continuous feedback loops where sensor units constantly detect body size and position, transmit this information to a control system, which then continuously adjusts the light projection parameters. This closed-loop feedback mechanism enables real-time continuous adaptation to changing body positions and orientations
4Productivity
If manual adjustment is required, then device complexity is low, but productivity and service efficiency are reduced
Solution Approach 1:
The system automatically detects passenger presence, body position, and orientation, then self-adjusts the light projection parameters without requiring passenger intervention. This self-service capability eliminates manual adjustment time and continuously optimizes lighting conditions, significantly improving service efficiency and productivity
