Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If half mirrors and LEDs are used to realize stereoscopic effect, then visibility and interest are improved, but user interfaces for dynamic environments cannot be provided
Solution Approach 1:
The system dynamically switches between different display modes (stereoscopic mode and 2D mode) based on driving conditions. The processor controls the LED light source to be turned on or off according to display mode setting information, enabling the interface to adapt to different dynamic environments such as nighttime driving or tunnel conditions.
Solution Approach 2:
The cluster display system serves multiple functions: it can display stereoscopic 3D information for normal driving conditions, switch to 2D display mode for specific scenarios, and provide both display-only and simultaneous use areas. This multi-functionality allows a single system to handle various driving environments effectively.
2Loss of information
If LED light source is turned on for simultaneous use area, then driving information with stereoscopic sense is displayed, but energy consumption increases
Solution Approach 1:
The system dynamically controls the LED light source based on display mode setting information. The processor determines when to turn the LED on or off according to driving conditions, ensuring energy is consumed only when stereoscopic display is actually needed for safe driving information presentation.
3Adaptability or versatility
If cluster is divided into display-only area and simultaneous use area, then information display flexibility is improved, but device complexity increases
Solution Approach 1:
The cluster display is segmented into different functional areas: a display-only area and a simultaneous use area. This segmentation allows independent control of different regions, enabling flexible display modes where the simultaneous use area can show both 2D and 3D information while the display-only area shows 2D information.
Solution Approach 2:
The simultaneous use area is designed to perform multiple functions: it can display 2D information and 3D stereoscopic information simultaneously or alternately based on driving conditions. This multi-functional design provides display flexibility without requiring completely separate systems for different display needs.
