Vehicle Display System with Driver-Adaptive Tilt Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric mirror systems for vehicles fail to adjust the display of rear camera images based on the driver's position, leading to degraded visibility of vehicle surroundings.
Innovation Solution
A display system that includes camera modules, display panels, driver pupil detection sensors, posture detection sensors, and a calculator to calculate display correction values, allowing for automatic adjustment of the tilt of display panels to align with the driver's field of view, improving visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a display module is fixed without regard to driver state, then device complexity is reduced, but visibility of vehicle surroundings is degraded
Solution Approach 1:
The display panel is made dynamically adjustable through a tilt control mechanism that changes its viewing angle based on driver position. The system transitions from a fixed display to one that can rotate and tilt to match the driver's line of sight, resolving the contradiction between simplicity and visibility.
Solution Approach 2:
The system uses sensors to detect driver position and provides feedback to the tilt control mechanism, which automatically adjusts the display angle. This closed-loop feedback system maintains optimal visibility without requiring complex manual adjustment mechanisms.
2Reliability
If display tilt is manually adjusted, then visibility is improved, but ease of operation is worsened
Solution Approach 1:
The display system performs self-adjustment through automatic tilt control based on sensor-detected driver position. The system serves itself by autonomously optimizing the display angle without requiring driver intervention, eliminating the operational burden while maintaining visibility.
Solution Approach 2:
Manual mechanical adjustment is replaced with an automated control system that uses sensors and actuators to adjust the display tilt. This substitution eliminates the need for manual operation while achieving the same visibility improvement.
3Adaptability or versatility
If multiple sensors and adjustment mechanisms are added, then adaptability to driver position is improved, but device complexity increases
Solution Approach 1:
The tilt control mechanism serves multiple functions: it adjusts display angle, tracks driver movement, and optimizes viewing conditions. By making this single mechanism multi-functional, the system achieves high adaptability without proportionally increasing complexity.
Solution Approach 2:
The system pre-positions the display panel using tilt adjustment mechanisms before the driver needs to view it. Sensors detect driver approach and pre-adjust the display angle, ensuring optimal visibility is ready in advance without requiring complex real-time adjustment mechanisms.
