Vehicle Display Screen Dual Mode Input Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display systems for motor vehicles lack the ability to easily choose which input device is displayed on a particular side or region of the screen in dual display mode, leading to inconvenient viewing experiences for passengers who may want to watch different content on each side of the screen.
Innovation Solution
A video display system with a display screen configured to alternate between single and dual display modes, featuring left and right external input ports physically located on a rear console, allowing for separate video signals to be displayed on each side, with shared audio input ports and the option to connect external video devices, enabling automatic switching between single and dual display modes based on signal presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display screen is configured to display two images simultaneously in dual display mode, then passenger entertainment capability is improved, but it becomes difficult to choose which input device is displayed on a particular side or region of the screen
Solution Approach 1:
The patent applies asymmetry by providing separate left and right external input ports that are physically distinct and asymmetrically positioned on the display device. This allows each port to be naturally associated with a specific side of the screen, eliminating the complexity of manually assigning input devices to screen regions. The left input port connects to the left image portion and the right input port connects to the right image portion, creating an intuitive asymmetric mapping that simplifies operation while maintaining dual display capability.
2Adaptability or versatility
If manual switching is required to change display modes, then display control flexibility is improved, but operation complexity and user burden increase
Solution Approach 1:
The patent implements self-service by enabling the display device to automatically detect the presence and type of input signals from external devices and autonomously switch between single and dual display modes without requiring manual user intervention. The system monitors the input ports and automatically configures the display accordingly, reducing operational complexity while preserving display mode flexibility through automatic adaptation to user needs.
Solution Approach 2:
The patent uses feedback mechanisms where the display device continuously monitors the status of external input ports and automatically adjusts display mode based on detected signal presence. When signals are detected from both left and right input ports, the system automatically switches to dual display mode; when only one signal is present or neither is present, it automatically switches to single display mode. This feedback-driven automatic control simplifies operation while maintaining flexibility.
3Adaptability or versatility
If multiple physically distinct display screens are used, then each passenger can view different content independently, but device space requirements and system complexity increase
Solution Approach 1:
The patent applies merging by combining the functionality of multiple physically distinct display screens into a single display device that can operate in both single and dual display modes. By integrating left and right image portions into one physical display unit with corresponding left and right input ports, the system provides independent viewing capability for multiple passengers while reducing the space requirements and system complexity that would result from using separate display screens for each passenger.
