Vehicle Front Display Linkage Control for Occupant Face Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices struggle to effectively adjust their position and orientation to accommodate the varying facial positions of drivers and passengers, leading to suboptimal viewing experiences and increased demand for enhanced usability and convenience information display.
Innovation Solution
A display device equipped with a drive module that includes a ball screw member and link member, utilizing a four-bar linkage structure to adjust the display's position and orientation based on the position of a specific facial portion of the occupant, controlled by a camera and processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device uses a fixed position and orientation, then the device complexity is reduced, but the adaptability to different occupant facial positions deteriorates
Solution Approach 1:
The display device employs a drive module with a ball screw member and link member that enables dynamic adjustment of the display's position and orientation. The ball screw member converts rotational motion to linear motion, driving the link member to pivot and position the display at different angles and locations, allowing adaptation to various occupant facial positions while maintaining manageable complexity through mechanical automation
Solution Approach 2:
The system uses a camera to detect the occupant's facial position and automatically controls the drive module to adjust the display orientation accordingly. This self-service mechanism eliminates the need for manual intervention, allowing the display to adapt to different occupants automatically without increasing operational complexity for the user
2Adaptability or versatility
If the display device adds adjustment mechanisms, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The link member acts as an intermediary between the ball screw member and the display device. It translates the linear motion from the ball screw into pivoting motion, enabling orientation adjustment without requiring complex direct mounting mechanisms. This intermediary component simplifies the overall adjustment mechanism while achieving both position and orientation control
3Ease of operation
If the display device is positioned optimally for each occupant, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The system incorporates a camera that continuously monitors the occupant's facial position and provides feedback to the control system. Based on this feedback, the drive module automatically adjusts the display orientation to optimize viewing comfort. This closed-loop feedback mechanism achieves optimal positioning automatically, maintaining ease of operation without requiring complex manual adjustment interfaces
