Dual-Face Vehicle Display for Occupant Posture Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles capable of autonomous driving, occupants may experience difficulty viewing information displayed on screens due to changes in their posture, leading to reduced visibility of display parts.
Innovation Solution
A vehicle display device comprising a detection system that identifies the occupant's orientation and posture, and a control system that adjusts the display to ensure information is shown on the most visible face, allowing for expansion or contraction of displayed content based on distance and projector adjustments for optimal viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display part is fixed at a specific location, then the device complexity is reduced, but the visibility of information becomes poor when the occupant changes posture
Solution Approach 1:
The display face is made movable rather than fixed, allowing it to dynamically adjust its orientation and position based on the detected occupant posture. The display control unit rotates and positions the display face to face the occupant, ensuring continuous visibility regardless of posture changes.
Solution Approach 2:
The system uses posture detection to continuously monitor occupant position and feeds this information back to the display control unit. Based on this feedback, the display face automatically adjusts its orientation and position to maintain optimal visibility for the occupant.
2Adaptability or versatility
If multiple display faces are provided, then the visibility for different postures is improved, but the device complexity increases
Solution Approach 1:
The display part is divided into multiple display faces that can be independently oriented and positioned. Each display face can be selectively activated and oriented toward the occupant based on detected posture, providing tailored visibility without requiring a completely different display system for each posture.
3Reliability
If the display face is moved to follow the occupant, then the visibility is maintained, but the ease of operation decreases due to automatic control
Solution Approach 1:
The display system automatically detects occupant posture and self-adjusts the display face orientation and position without requiring manual intervention. The posture detection unit continuously monitors and the display control unit autonomously positions the display, making the system self-adapting to occupant needs.

AI summary
A vehicle display device that includes: a display part having a front-side display part and a rear-side display part provided inside a vehicle cabin, each of the front-side display part and the rear-side display part having a display face; a detection part that detects an orientation and a posture of an occupant; and a control part that selects a display face in accordance with the orientation and the posture of the occupant detected by the detection part, raises the selected display face, and controls display by the display part such that information is displayed at the selected display face.
