Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional display systems are used to present driving information, then the device complexity is low, but the intuitiveness and user perception of safety-related driving information deteriorates
Solution Approach 1:
The patent introduces a light synthesizing unit that combines light from multiple displays to create a three-dimensional depth effect. This dimensional transformation allows driving information to be presented with perceived depth and spatial layering, making safety-critical information more intuitive and distinguishable without adding complex mechanical moving parts.
Solution Approach 2:
The light synthesizing unit acts as an intermediary between multiple displays and the user's eye. It receives light from the first and second displays, combines them with different intensities, and presents a synthesized visual output that creates the three-dimensional depth effect, simplifying the overall system architecture while achieving enhanced information presentation.
2Loss of information
If multiple displays are used to present different driving information, then the information completeness improves, but the visual clarity and user understanding deteriorates due to lack of depth perception
Solution Approach 1:
By introducing the light synthesizing unit that creates a three-dimensional depth effect, the patent enables the user to visually distinguish between different layers of driving information. Safety-related information can be presented with enhanced depth perception, making it easier to detect and understand critical information while maintaining complete information display.
3Ease of manufacture
If a simple display structure is used, then the manufacturing cost is low, but the ability to create three-dimensional depth effect and enhance user perception deteriorates
Solution Approach 1:
The light synthesizing unit serves as a cost-effective intermediary that creates three-dimensional depth effects by optically combining light from multiple displays. This approach avoids the need for complex mechanical 3D display mechanisms or expensive specialized components, achieving enhanced visual perception through relatively simple optical elements.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables the intuitive display of driving information, improving safety by creating a three-dimensional depth effect that enhances user understanding and awareness of critical driving conditions.
Implementation Method 1
configured to transmit therethrough the first light from the first display and reflect the second light from the second display
Implementation Method 2
tilt the first tiltable reflector to form a first angle with the second display so the first tiltable reflector reflects part of the second light directed toward the light synthesizing unit toward a first direction
Implementation Method 3
tilt the second tiltable reflector to form a second angle with the first display so the second tiltable reflector reflects part of the first light directed toward the light synthesizing unit toward a second direction different from the first direction
