Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are installed to provide diverse information from cameras and sensors, then the display area is increased, but the power consumption increases
Solution Approach 1:
The display system is divided into multiple independent display panels, each capable of being controlled separately. This allows the system to segment the display area into functional regions that can be independently powered on or off based on driving conditions, thereby maintaining large display capability while reducing overall power consumption when full display area is not needed.
Solution Approach 2:
The control system periodically evaluates driving conditions and adjusts which display panels are active. By implementing periodic monitoring and control of display panel activation, the system can reduce power consumption during periods when certain display information is not required while maintaining readiness to display information when needed.
2Adaptability or versatility
If display panels are installed on curved surfaces to fit car interior space, then the adaptability to car interior is improved, but the manufacturing complexity increases
Solution Approach 1:
The invention employs display panels with curved surfaces that can conform to the curved interior surfaces of vehicles. By designing panels with inherent curvature capability, the system achieves adaptability to various car interior geometries without requiring complex mechanical mounting structures or post-installation shaping processes.
Solution Approach 2:
The display panels utilize flexible substrate structures that enable bending and conforming to curved surfaces. This flexibility allows the panels to adapt to irregular car interior geometries while maintaining manufacturing feasibility through standard flexible display fabrication techniques rather than requiring complex rigid structure fabrication.
3Area of stationary object
If multiple display panels overlap to form one display region, then the display area is increased, but the video discontinuity at seams occurs
Solution Approach 1:
The system implements feedback mechanisms that monitor the display output across multiple panels and dynamically adjust image rendering to compensate for seam visibility. By continuously monitoring display conditions and adjusting content distribution, the system reduces perceived discontinuity at panel boundaries while maintaining expanded display area.
Solution Approach 2:
The invention employs color and brightness adjustment techniques at panel boundaries to reduce visual discontinuity. By dynamically modifying the optical properties of display elements near seams, the system creates smoother transitions between panels, making the segmented structure less perceptible while maintaining the benefits of expanded display area.
4Area of stationary object
If a large display panel with large thickness is installed on dashboard, then the display area is increased, but the driver's field of vision is obstructed
Solution Approach 1:
The large display area is achieved through segmentation into multiple thinner panels rather than a single thick panel. This segmentation allows each panel to be positioned at optimal thickness while collectively providing the desired large display area, reducing overall obstruction to the driver's field of vision.
Solution Approach 2:
The use of curved surface panels allows the display to conform to the dashboard geometry, positioning the display elements in three-dimensional space more efficiently. This curvature enables large display area while maintaining thinner profile and reducing obstruction to the driver's forward view compared to flat panels of equivalent area.

AI summary
A plurality of display panels having a curved surface are placed in a limited space.Two, or three or more display panels are combined to form one display region having a T-shaped outer edge as one screen, and a driver can curve part of the display panel as appropriate so that the driver can see the screen easily. A first display panel or a second display panel has flexibility and includes a position adjustment function of curving an end portion. That is, by curving part of the display panel, the user can see the display panel easily. The in-car design can also be varied.
