Windshield Entertainment Display Layout for Driver Neck Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automobiles that allow entertainment in the cabin, such as racing games, cause neck fatigue due to the display being positioned on the center console, directing the driver's line of sight downward.
Innovation Solution
The display is positioned on the windshield or a flexible display between the steering wheel and windshield, allowing it to be raised or lowered, enabling entertainment without compromising forward visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is positioned on the center console to enable entertainment, then entertainment functionality is achieved, but the driver's line of sight is directed downward causing neck fatigue
Solution Approach 1:
The display is moved from the horizontal center console plane to the vertical windshield plane, changing the spatial dimension of display placement. This allows the display to be positioned in the driver's forward line of sight without requiring downward head movement, thereby eliminating neck fatigue while maintaining entertainment functionality
Solution Approach 2:
The windshield serves as an intermediary surface between the driver and the entertainment content. By projecting or displaying content on the windshield, the system mediates the interaction between the driver and entertainment, allowing content consumption without compromising driving posture or visibility
2Adaptability or versatility
If the display is positioned on the center console, then entertainment can be enjoyed, but forward visibility is compromised due to downward gaze
Solution Approach 1:
The display transitions from a horizontal center console position to a vertical windshield position, utilizing the vertical dimension of the windshield area. This repositioning places the display within the driver's natural forward viewing zone, eliminating the need to look downward and thus preserving forward visibility while maintaining entertainment capability
Solution Approach 2:
The windshield serves multiple functions: it maintains its primary function as a transparent barrier for forward visibility while simultaneously serving as a display surface for entertainment content. This multi-functionality allows the same component to support both driving safety and entertainment needs

AI summary
An automobile includes an entertainment execution device, a display device and a mode select controller. The entertainment execution device executes entertainment software, communicates with radio control equipment, or plays back a video content. The display device displays an image output from the entertainment execution device on a windshield or on a flexible display capable of being raised or lowered between a front windshield and a steering wheel. The mode select controller enables selection between an entertainment mode for operating the entertainment execution device and a driving mode for driving the automobile and executes control according to each mode. The mode select controller controls the display device to display the image output in a first region of the windshield in the driving mode, and to display the image output in a second region of the windshield or on the flexible display in a raised state in the entertainment mode.
