Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed display is installed in a vehicle, then the display provides stable visual information, but the space utilization is limited and forward visibility decreases as display size increases
Solution Approach 1:
The display device transitions from a fixed installation to a movable one, capable of moving up and down or left and right relative to the dashboard along a guide. This dynamic positioning allows the display to be adjusted to optimize both space utilization and forward visibility while maintaining stable visual information presentation when positioned.
2Area of stationary object
If a pop-up style movable display is used, then space utilization improves, but the accommodation space size increases with display size and power consumption is inefficient
Solution Approach 1:
The display device operates in partial action mode by controlling the exposure area of the display screen. Only the necessary portion of the display is exposed and activated based on user needs, rather than operating the entire screen. This reduces power consumption proportionally to the exposed area while maintaining the pop-up style movable structure for improved space utilization.
3Ease of operation
If the display is always fully exposed, then all visual information is accessible, but power consumption increases regardless of the degree of exposure needed
Solution Approach 1:
The display device implements dynamic exposure control where the display screen can be partially or fully exposed based on operational requirements. The display driver controls the degree of exposure by moving the display part along the guide, allowing the system to adapt between full information accessibility and power-saving modes depending on user needs.
Solution Approach 2:
The system changes the exposure parameter of the display screen dynamically. By adjusting the position of the display part along the guide, the exposed area parameter is varied, enabling the display to operate at different power consumption levels while maintaining information accessibility when fully exposed.
