In-Vehicle Display Redundancy Resolution via Local Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle information display devices with multiple displays often present redundant content, degrading user-friendliness as existing technologies do not account for identical content being displayed on multiple units, leading to a lack of useful information without increasing user operations.
Innovation Solution
Implementing a system where the first and second display devices in a vehicle interior compare their content and automatically switch to associated alternative content when identical, ensuring that useful information is provided without redundant displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all functions are realized in each of the several displays, then each display can independently perform navigation and meter display functions, but identical content is displayed on multiple displays causing redundancy and degrading user-friendliness
Solution Approach 1:
The patent applies local quality by assigning different display modes to different displays based on their spatial characteristics. The first display (upper) shows map information suitable for its position, while the second display (lower) shows meter information suitable for its position, eliminating redundant content while maintaining functional versatility.
Solution Approach 2:
The system dynamically switches between different display content configurations. When the vehicle is stationary, both displays can show the same content for flexibility. When the vehicle is moving, the system automatically differentiates content to eliminate redundancy, making the displays adaptive to operational conditions.
2Stability of the object's composition
If identical content is displayed on multiple displays, then each display can show the same information for consistency, but the redundancy degrades user-friendliness by providing less useful information
Solution Approach 1:
Different displays are assigned different types of information based on their spatial locations. The upper display shows map data while the lower display shows meter data, ensuring each display provides locally appropriate information without redundancy, thus preventing information loss while maintaining operational consistency.
Solution Approach 2:
The patent segments the information display function into different types: map information on the first display and meter information on the second display. This segmentation eliminates redundant identical content while ensuring each display provides useful, non-overlapping information.
3Ease of operation
If the system automatically changes content when identical content is detected, then user-friendliness is improved by providing diverse useful information, but the system complexity increases due to content comparison and switching logic
Solution Approach 1:
The system performs preliminary actions by pre-defining the correspondence between first and second display content types. The control unit is pre-programmed with the logic to identify when both displays show identical content and automatically switch to alternative content, reducing the need for complex real-time decision-making algorithms.
Solution Approach 2:
The system serves itself by automatically detecting identical content on both displays and autonomously switching one display to show alternative content. This self-service mechanism eliminates the need for manual user intervention or complex external control systems, thereby reducing overall system complexity while improving user-friendliness.

AI summary
In a vehicle interior, a first navi-display (10) and a second navi-display (20) are arranged beforehand. It is determined whether or not a content displayed on the first navi-display (10) and a content displayed on the second navi-display (20) are identical to each other. When it is determined that they are identical to each other, the content that has been determined to be identical and that was displayed earlier on either one of the first navi-display (10) or the second navi-display (20) is changed to another content associated beforehand with the content that has been determined to be identical.
