Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the imaging position is fixed, then the device structure is simple, but the driver needs to frequently adjust the display position according to driving conditions
Solution Approach 1:
The patent implements dynamic adjustment of the intermediate image receiving position based on driving conditions. The controller receives driving condition information (speed, weather, road conditions) and automatically adjusts the intermediate image receiving position accordingly, transforming the static display system into a dynamic one that adapts to changing conditions without requiring driver intervention.
Solution Approach 2:
The display system performs self-adjustment based on driving conditions. The controller automatically modifies the intermediate image receiving position according to sensor data about speed, weather, and road conditions, eliminating the need for manual driver adjustment and making the system serve itself.
2Adaptability or versatility
If the driver frequently adjusts the display position, then the display can adapt to different conditions, but driver fatigue increases and safety decreases
Solution Approach 1:
The system incorporates feedback mechanisms by receiving driving condition information from sensors (speed sensors, weather sensors, road condition sensors) and using this feedback to automatically adjust the intermediate image receiving position. This closed-loop control ensures the display adapts to conditions without requiring driver attention or action.
Solution Approach 2:
The display system automatically adjusts itself based on driving conditions, performing the adaptation function without driver involvement. This eliminates the safety risk associated with driver distraction while maintaining full adaptability to changing conditions.
3Adaptability or versatility
If the intermediate image receiving position is changeable, then the image can be displayed at the optimal position for current conditions, but the device complexity increases
Solution Approach 1:
The patent implements dynamic adjustment of the intermediate image receiving position based on driving conditions. The controller receives driving condition information (speed, weather, road conditions) and automatically adjusts the intermediate image receiving position accordingly, transforming the static display system into a dynamic one that adapts to changing conditions without requiring driver intervention.
Solution Approach 2:
The system changes the position parameter of the intermediate image receiving part based on driving conditions. By adjusting this key parameter dynamically, the system achieves adaptability while managing complexity through focused parameter control rather than complete system redesign.
