Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If display brightness is increased to improve visibility, then display effect is improved, but it causes glare and affects driver safety in bright environments
Solution Approach 1:
The display brightness is dynamically adjusted based on real-time ambient light detection. The system transitions from static brightness settings to dynamic adaptation, automatically modifying display parameters according to environmental conditions to maintain visibility while preventing glare.
Solution Approach 2:
The system implements a feedback mechanism where ambient light sensors continuously monitor environmental illumination levels and feed this information back to the display control system. This closed-loop control enables automatic brightness adjustment, ensuring the display adapts to changing light conditions without manual intervention.
2Object-affected harmful factors
If display brightness is decreased to reduce glare in bright environments, then driver safety is improved, but visibility of display content deteriorates
Solution Approach 1:
The display system applies different brightness levels to different regions or elements. Critical safety information maintains higher visibility while less critical elements are dimmed, creating a hierarchical brightness structure that balances overall glare reduction with essential information visibility.
Solution Approach 2:
The system adjusts not only brightness but also color characteristics of the display. By modifying color temperature and hue in response to ambient light conditions, the display maintains contrast and readability while reducing harsh glare effects in bright environments.
3Ease of operation
If display mode remains static to simplify system operation, then ease of operation is improved, but adaptability to environmental changes deteriorates
Solution Approach 1:
The display system performs self-adjustment based on environmental sensing without requiring user intervention. The automated brightness and mode adaptation eliminates the need for manual controls, allowing the system to serve itself in adapting to changing conditions while maintaining operational simplicity.
Solution Approach 2:
The system proactively adjusts display parameters before environmental conditions significantly impact visibility. By detecting ambient light changes in advance and pre-adjusting brightness levels, the system maintains optimal display performance without requiring reactive user input.
4Adaptability or versatility
If multiple display parameters are adjusted to improve environmental adaptation, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system combines multiple display parameter adjustments into a unified control framework. By integrating brightness, contrast, and color temperature adjustments under a single adaptive control system, the patent reduces the complexity of managing multiple independent parameters while maintaining comprehensive environmental adaptation.

AI summary
A display method includes: obtaining environment information corresponding to a vehicle, where the environment information includes light intensity information and/or location information; and adjusting a display mode of a display device of the vehicle based on the environment information, where the display mode includes at least one of display brightness, a display location, display content, a display color, a display style, or a display size. Hence, the display mode of the display device is adjusted based on the environment information such that the display mode of the display device can adapt to a current environment to improve display effect and driving safety.
