Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If images are displayed on a fixed display device inside the vehicle, then passengers can view images, but the images do not change perspective when the vehicle moves, reducing realism
Solution Approach 1:
The display device is configured to rotate about a rotation axis extending in the vehicle width direction, enabling dynamic adjustment of the display orientation. This allows the display surface normal to track the vehicle's movement direction, maintaining realistic image perspective despite vehicle motion. The rotational mechanism transforms a static display into a dynamic one that adapts to changing vehicle orientation.
2Reliability
If the display device rotates to track vehicle movement, then image realism improves, but the mechanical structure becomes more complex
Solution Approach 1:
The display system is divided into independently controllable segments: the rotation mechanism for orientation adjustment and the image generation unit for content creation. This segmentation allows the rotation function to be optimized separately from the image processing, reducing overall system complexity while maintaining realism.
Solution Approach 2:
The rotation mechanism serves multiple functions: it adjusts display orientation for realism, optimizes viewing angles for different passenger positions, and can potentially accommodate different types of display content. This multi-functionality reduces the need for separate mechanisms, thereby reducing overall device complexity.
3Reliability
If images are generated based on actual vehicle surroundings, then realism improves, but processing time and computational load increase
Solution Approach 1:
The system captures actual vehicle surroundings in advance using imaging devices and pre-processes this data into base image content. This preliminary action allows the main processing unit to work with pre-prepared data rather than generating images from raw sensor data in real-time, significantly reducing processing time while maintaining realism.
Solution Approach 2:
A control device acts as an intermediary between the imaging devices and the image generation unit. It manages the flow of data, coordinates the capture and processing of surrounding environment data, and optimizes the timing of image generation. This intermediary layer reduces computational burden on the main processing unit and optimizes real-time performance.

AI summary
An image display system of a transportation means and an image display method of the transportation means are provided, and pertain to the field of image display technologies. In the image display system and the image display method, a first transmission path and a second transmission path are established between a control module and a display module. The control module may compare first image data transmitted through the first transmission path with second image data transmitted through the second transmission path, to determine that first displayed content is inconsistent with second displayed content, and therefore, to provide a reference basis for subsequent processing (for example, processing such as giving an alarm prompt or correcting the second displayed content) by the control module. According to the method, whether content displayed by the display module is accurate can be determined. If the content is inaccurate, subsequent processing may be performed in a timely manner, to ensure accuracy of an image displayed by the display module. This helps improve safety of a vehicle during use.
