Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the vehicle-mounted display angle is fixed, then the device complexity is reduced, but the adaptability to different sitting postures and viewing angles deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the display angle through a motor-driven rotation mechanism. The display can rotate around a rotation axis to change its inclination angle according to different viewing needs, transforming a static fixed-angle structure into a dynamic adjustable one that adapts to various sitting postures and viewing scenarios.
Solution Approach 2:
The system changes the display angle parameter dynamically based on detected driver gaze direction. By adjusting the inclination angle of the display screen, the system optimizes viewing comfort for different driver positions and postures,实现ing parameter-based adaptation without requiring multiple fixed displays.
2Adaptability or versatility
If manual adjustment of the display angle is required, then the adaptability to different viewing angles is improved, but the ease of operation deteriorates due to inconvenient adjustment
Solution Approach 1:
The system performs self-adjustment by automatically detecting the driver's gaze direction through eye tracking technology and autonomously rotating the display to the optimal angle. This eliminates the need for manual intervention, allowing the display to serve itself in adapting to different viewing conditions.
Solution Approach 2:
The system establishes a feedback loop where the driver's eye position and gaze direction are continuously monitored, and this information feeds back to the control system which automatically adjusts the display angle accordingly. This closed-loop control ensures the display remains optimally positioned without requiring manual adjustment.
3Adaptability or versatility
If the display angle is manually adjusted, then the adaptability to different viewing angles is improved, but the driving safety deteriorates due to excessive head turning or distraction
Solution Approach 1:
The display system automatically adjusts itself based on eye tracking data, eliminating the need for drivers to manually reach for or adjust the display. This self-adjusting capability prevents drivers from taking their eyes off the road or turning their heads excessively to find the optimal viewing angle.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated motor-driven rotation system controlled by eye tracking technology. This substitution eliminates the need for physical interaction with the display adjustment mechanism, thereby maintaining driving safety while achieving adaptability to different viewing angles.
