Vehicle Multi-Image Display Reflection for Rear-Seat Entertainment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display technologies do not effectively provide entertainment to rear seat passengers without adding additional hardware, while ensuring interior openness and safety during autonomous driving.
Innovation Solution
A vehicle display control apparatus that includes a multi-image display device capable of outputting images at different angles or optical frequencies, a reflection member on the vehicle's ceiling for image reflection, and a controller to manage image output based on user inputs, vehicle status, and emergency situations, without additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display is provided on the back surface of a front seat headrest to provide content to rear seat passengers, then rear seat passenger entertainment is improved, but interior openness is reduced and additional hardware is required
Solution Approach 1:
The front display device is designed to serve multiple functions: it provides content to both front seat drivers/passengers and rear seat passengers simultaneously through multi-angle output capability, eliminating the need for separate dedicated displays for different seating positions
Solution Approach 2:
A reflection member (such as a mirror or reflective surface) is introduced as an intermediary element to redirect light from the front display to the rear seat area, enabling rear passengers to view content without requiring a display mounted in their vicinity
2Adaptability or versatility
If a display is provided on the back surface of a front seat headrest to provide content to rear seat passengers, then rear seat passenger entertainment is improved, but interior openness is reduced
Solution Approach 1:
The reflection member acts as a mediator that allows the display content to reach rear passengers without physically occupying space in the rear seating area, thus preserving interior openness while still delivering entertainment functionality
3Adaptability or versatility
If images are continuously output to rear seat passengers during autonomous driving, then rear seat passenger entertainment is improved, but safety is reduced in emergency situations
Solution Approach 1:
The system dynamically adjusts its operation based on real-time conditions: during normal autonomous driving, it provides entertainment content to rear passengers; upon detecting emergency situations, it automatically suspends content output to prioritize safety and alertness
Solution Approach 2:
The system incorporates feedback mechanisms that monitor driving status and emergency conditions, using this information to control whether content is output to the display, ensuring that entertainment functionality does not compromise safety requirements
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
Enhances rear seat passenger entertainment, maintains interior openness, and ensures safety by dynamically controlling image output based on driving conditions, such as emergencies or approaching destinations.
Implementation Method 1
a first reflection member provided in an indoor ceiling of the vehicle and reflecting one image among the two or more images output from the multi-image display device
