In-Vehicle Display Apparatus for Information Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle display systems overwhelm drivers and passengers with mixed information on a single display, making it difficult to view and understand specific information, and fail to effectively convey priority information to the driver.
Innovation Solution
An in-vehicle display apparatus featuring a first display device integrated into the instrument panel and a second display device positioned nearby, displaying information in coordination to provide clear, role-specific content, enhancing visibility and dynamism within the cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single display device is used to show all information, then device complexity is reduced, but information clarity and understandability deteriorate
Solution Approach 1:
The patent divides the display system into multiple independent display devices (first display device on instrument panel, second display device on dashboard or window) to segment different types of information. This allows critical driving information to be separated from entertainment or secondary information, resolving the contradiction by improving information clarity through spatial segmentation while managing overall system complexity.
Solution Approach 2:
The patent transitions from a single-dimensional display (one screen) to a multi-dimensional display arrangement by placing display devices in different spatial locations within the cabin. The first display device is positioned on the instrument panel within reach of the driver, while the second display device is positioned on the dashboard or window area, creating a three-dimensional information distribution that enhances clarity without simply adding more devices everywhere.
2Adaptability or versatility
If multiple display devices are disposed in the cabin, then information variety increases, but information priority and attention guidance deteriorate
Solution Approach 1:
The patent assigns different functional qualities to different display devices based on their locations. The first display device on the instrument panel is optimized for critical driving information that requires immediate driver attention, while the second display device positioned elsewhere handles secondary information like entertainment or navigation. This local quality differentiation ensures information priority is maintained through spatial-functional mapping.
Solution Approach 2:
The patent introduces a control unit that acts as an intermediary between the information source and the display devices. This control unit intelligently distributes information to appropriate display devices based on priority, type, and driver needs, ensuring that even with multiple display devices showing varied information, the priority hierarchy is maintained through centralized coordination.
3Ease of operation
If display information is not positioned suitably, then ease of viewing improves, but information transmission efficiency deteriorates
Solution Approach 1:
The patent performs preliminary action by pre-positioning different types of information on display devices according to their expected utility and driver attention patterns before the driving situation arises. Critical information is pre-placed on the instrument panel within the driver's natural field of view, while secondary information is pre-positioned on the dashboard or window displays, ensuring both ease of viewing and transmission efficiency are optimized in advance.
Data Source
AI summary
A display unit incorporated in the housing surface of an instrument panel on the passenger seat side changes its display variously together with other display devices such as a liquid crystal display and a line illumination, and displays information such as driving information, danger notification information and entertainment information in coordination.
