Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display size is increased to provide more information output, then the information display capability is improved, but the driver's forward view is obstructed
Solution Approach 1:
The display device transitions from a static large-screen configuration to a dynamic reconfigurable system that can change its shape and position. The display panel is divided into multiple segments that can be independently positioned and oriented, allowing the system to adapt between providing large display area and maintaining clear forward view by reconfiguring the display segments.
Solution Approach 2:
The display panel is divided into multiple independent display segments or modules. These segments can be separately positioned, oriented, and configured to display different information. This segmentation allows the system to provide sufficient display area while arranging segments in configurations that minimize obstruction to the driver's forward view.
2Adaptability or versatility
If the display device is made flexible to enable shape changing, then the adaptability to vehicle status is improved, but the structural reliability deteriorates
Solution Approach 1:
The display device incorporates flexible display panels and thin-film structures that enable bending and shape changes. These flexible components are designed to withstand repeated deformation cycles while maintaining display quality and structural integrity, allowing the device to adapt its shape according to vehicle status without compromising reliability.
Solution Approach 2:
The system includes support structures and control mechanisms that prepare and guide the flexible display through deformation transitions. By providing structural support during shape changes and controlling the deformation process, the system prevents damage to the flexible components and ensures reliable operation throughout the adaptability cycles.
3Device complexity
If a single motor is used to power both linear and curved motions, then the device complexity is reduced, but the motion control precision deteriorates
Solution Approach 1:
A single motor is designed to perform multiple functions by generating both linear and curved motions through a carefully designed transmission mechanism. The motor serves as a universal actuator that can produce different types of movement required for the display device's shape changing, thereby reducing the number of motors while maintaining control precision through mechanism design.
Solution Approach 2:
A transmission mechanism acts as an intermediary between the single motor and the display panel. This intermediary mechanism converts the motor's rotational output into both linear and curved motions, enabling precise control of the display's shape changes. The transmission mechanism ensures that the single motor can accurately control complex multi-degree-of-freedom movements.
