Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display area is increased to provide more detailed information, then the quantity of information displayed is improved, but the device complexity increases due to the need for flexible display mechanisms and sensors
Solution Approach 1:
The display device employs a flexible display that can dynamically change its area size based on driving conditions. The display transitions between extended and retracted states, allowing the system to adapt the information presentation area to match the complexity of current driving conditions, thereby providing more information when needed without permanently increasing device complexity
Solution Approach 2:
The system changes the physical parameter of display area size in response to varying driving conditions. Sensors detect parameters such as vehicle speed and collision risk, and the controller adjusts the flexible display area accordingly, optimizing information display completeness while managing device complexity through conditional parameter adjustment
2Reliability
If the display area is retracted to minimize distraction during high-speed driving, then the safety is improved, but the quantity of information that can be displayed is reduced
Solution Approach 1:
The flexible display dynamically adjusts its area between extended and retracted states based on real-time driving conditions. During high-speed driving or critical situations, the display retracts to minimize driver distraction and enhance safety. During low-speed or stationary conditions, the display extends to provide comprehensive information, thus balancing safety requirements with information accessibility needs
Solution Approach 2:
The system proactively reduces the display area before potential safety issues arise by detecting high-speed driving conditions or collision risks in advance. The flexible display automatically retracts when sensors indicate conditions that require minimal distraction, preventing information overload before it becomes a safety hazard
3Loss of information
If multiple fixed displays are mounted to provide comprehensive information, then the information coverage is improved, but the ease of operation deteriorates due to inability to adapt to different usage environments
Solution Approach 1:
The flexible display serves multiple functions by dynamically adjusting its area based on usage environment. A single flexible display unit replaces the need for multiple fixed displays, as it can extend to provide comprehensive information when needed and retract when minimal information is required, thereby improving ease of operation while maintaining information coverage
Solution Approach 2:
The display system transitions from static fixed displays to a dynamic flexible display that adapts its area to different usage environments. The flexible display extends during parking or low-speed conditions to provide detailed information and retracts during high-speed driving for minimal distraction, enabling the system to adapt to varying operational requirements with a single versatile component
