Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If existing automotive display systems use fixed transmission display windows, then the system structure is simple, but glare cannot be effectively managed and luminance levels cannot be adjusted for varying lighting conditions
Solution Approach 1:
The patent applies dynamics by transitioning from fixed transmission display windows to variable-transmission display windows that can dynamically adjust their light transmission properties. The display window's transmission characteristics change in response to varying lighting conditions, allowing the system to adapt luminance levels actively rather than remaining static.
Solution Approach 2:
The patent implements parameter changes by modifying the transmission parameter of the display window. The variable-transmission display window changes its optical properties (transmission ratio) based on environmental lighting conditions, enabling effective glare management and luminance control without requiring complete system redesign.
2Reliability
If existing systems do not use directional light control, then the device complexity is low, but retinal damage risk increases and visibility is reduced in varying lighting conditions
Solution Approach 1:
The patent applies local quality by implementing directional control of light transmission at specific locations and angles. Rather than uniformly controlling light across the entire display window, the system selectively manages light transmission in specific directions and regions, targeting glare sources and protecting vulnerable areas while maintaining overall system simplicity.
3Ease of operation
If variable-transmission display windows are implemented, then glare management and luminance control are improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the variable-transmission display window to automatically adjust its transmission properties in response to environmental lighting conditions. The system monitors lighting levels and autonomously modifies its optical characteristics without requiring manual intervention, thereby improving ease of operation while managing complexity through automation.
4Adaptability or versatility
If existing systems lack environmental light painting capabilities, then the device complexity is low, but augmented reality features and collision warnings cannot be provided
Solution Approach 1:
The patent applies universality by designing the variable-transmission display window system to perform multiple functions: traditional display functionality, environmental light painting, augmented reality overlay, and collision warning capabilities. This multi-functional approach increases adaptability and versatility while managing complexity through integrated design rather than separate independent systems.
