Pivotable Dual-Sided Display for Vehicle Rear-Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rear-seat passenger entertainment systems mounted on the interior ceiling of vehicles often obstruct the driver's view of the center-mounted interior rear-view mirror, reducing visibility and potentially causing unsafe conditions.
Innovation Solution
A dual-sided display system with a pivotable display panel, including two cameras and a processor, that allows the display panel to be adjusted between positions to avoid obstructing the driver's view, providing additional information and views through the rear-view mirror, such as rear-view images or passenger monitoring, and automatically lowers when the vehicle is in reverse gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display panel is mounted on the interior ceiling for rear-seat passenger entertainment, then passengers can view entertainment content, but the display panel obstructs the driver's view of the interior rear-view mirror
Solution Approach 1:
The display panel is made movable rather than fixed, allowing it to be positioned in different locations. The panel can be moved to a first position where it does not obstruct the rear-view mirror and to a second position where it is visible to rear-seat passengers, thus resolving the contradiction between entertainment capability and driver visibility
Solution Approach 2:
The display panel is positioned in three-dimensional space such that it can be located in a first position away from the driver's line of sight to the rear-view mirror, and a second position where it is accessible to rear-seat passengers. This spatial dimensionality allows both functions to coexist without interference
2Adaptability or versatility
If the display panel is positioned to be viewable by rear-seat passengers, then entertainment functionality is provided, but the driver's field of vision is compromised
Solution Approach 1:
The display panel's position is made dynamic, allowing it to be moved between a first position that preserves driver safety and a second position that enables entertainment functionality. This dynamic positioning ensures that safety is maintained when the panel is in the first position while still allowing entertainment when needed
Solution Approach 2:
The display system is segmented into two distinct positions: a first position optimized for driver safety with unobstructed view of the rear-view mirror, and a second position optimized for passenger entertainment. The system can switch between these segmented states based on operational requirements
3Object-affected harmful factors
If the display panel is made movable to avoid obstruction, then driver visibility is improved, but device complexity increases
Solution Approach 1:
The display panel is made movable through a hinge mechanism that allows rotation between positions. This dynamic element adds complexity to the device structure, enabling the panel to be positioned away from the driver's view when needed while maintaining a relatively simple mechanical implementation

AI summary
A display system for a vehicle including a dual-sided display panel pivotably mounted to the interior ceiling of the vehicle. The dual-sided display panel displays an image from a media device to a rear-seat passenger of the vehicle and displays a different image to the driver on a second side of the display panel. The second side of the display panel is viewable by a driver of the vehicle through a rear-view mirror. A user-operated switch indicates what video source is displayed to the driver on the second side of the display panel. A first selectable video source is a camera mounted on the rear of the vehicle to capture rear-view images of the exterior behind the vehicle. A second selectable video source is a camera mounted in the rear passenger area of the vehicle to capture images of a rear-seat passenger.
