Vehicle Front Display Positioning via Facial Tracking Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices lack the ability to effectively adjust their position and orientation based on the driver's facial position, leading to suboptimal viewing angles and usability.
Innovation Solution
A display device with a drive module incorporating a ball screw member and link member, utilizing a four-bar linkage structure, adjusts the display's position and orientation through a camera that detects the driver's facial features, enabling linear, rotational, and curved movements.
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 driver positions deteriorates
Solution Approach 1:
The display device transitions from a fixed structure to a dynamic adjustable structure. The drive module enables the display to change its position and orientation dynamically based on the driver's facial position detected by the camera, resolving the contradiction between adaptability and complexity by introducing controlled motion mechanisms.
Solution Approach 2:
The system implements self-adjustment by using the camera to detect the driver's facial position and automatically controlling the drive module to position the display optimally without requiring manual intervention from the driver, thereby improving adaptability while keeping the operation simple.
2Ease of operation
If the display device adds movement and tilting capabilities, then the usability for different drivers is improved, but the device complexity increases
Solution Approach 1:
The display device performs self-positioning by detecting the driver's facial features and automatically adjusting its position and orientation through the drive module, eliminating the need for manual adjustment while improving usability.
Solution Approach 2:
The system uses camera-based facial position detection as feedback to continuously monitor and adjust the display position, creating a closed-loop control system that optimizes usability through automatic adaptation to the driver's position.
3Manufacturing precision
If the display device remains stationary, then the manufacturing precision requirements are reduced, but the viewing angle optimization for different drivers deteriorates
Solution Approach 1:
The display device incorporates dynamic adjustment capabilities through the drive module, allowing it to change position and orientation based on detected facial positions. This dynamic capability enables viewing angle optimization for different drivers without requiring extremely precise fixed manufacturing tolerances.
Applied Scientific Principles
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 device provides optimal viewing by aligning the display with the driver's facial position, enhancing usability and safety through customizable display positioning and movement.
Implementation Method 1
a ball screw member connected to the link member and configured to move in a straight line and rotate the link member
Implementation Method 2
linked to a camera installed in the vehicle and configured to adjust a position of the front display based on a position of a specific facial portion of an occupant
