In-Vehicle Display Coordination and Windshield Light Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle display systems fail to effectively display information in a coordinated and easily understandable manner, leading to difficulty in viewing and understanding for both drivers and passengers, and lack a unified appearance due to the dispersion of information across multiple devices.
Innovation Solution
An in-vehicle display apparatus featuring a first display device integrated into the instrument panel, with additional display devices on either side, coordinated to display information in a unified and role-specific manner, utilizing a light source and surface panel to direct light towards the passenger seat, and a base material with step portions to fit the instrument panel, ensuring easy arrangement and preventing projection onto the windshield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple display devices are disposed in the cabin to display different information, then information quantity increases, but it becomes difficult to convey information preferentially and the arrangement lacks unity
Solution Approach 1:
The patent combines multiple display devices (first display device in instrument panel, second display device on left, third display device on right) into a coordinated display system. These devices display related information in coordination with each other, creating a unified visual presentation across multiple locations while maintaining arrangement unity through coordinated content display.
2Device complexity
If various information is displayed on one display device, then device quantity reduces, but information becomes hard to view and understand
Solution Approach 1:
The patent segments information display across multiple display devices positioned at different locations (instrument panel, left side, right side). Each display device shows specific types of information, allowing passengers to view and understand information more easily by presenting it in distributed, location-appropriate formats rather than consolidating all information on a single device.
3Illumination intensity
If light source is installed in the first display device, then information display capability improves, but light may be projected onto the windshield causing distraction
Solution Approach 1:
The patent applies local quality by installing a surface panel on the first display device that selectively directs light emission. The surface panel is designed with specific optical properties to guide light toward the passenger seat area while preventing light from projecting onto the windshield, thus creating localized light control with different directional characteristics in different regions.
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
The solution allows for easy-to-understand information display in a coordinated and unified fashion, enhancing passenger information transmission and improving the driver's ability to grasp the entire display, while maintaining a cohesive appearance and preventing light projection onto the windshield.
Implementation Method 1
a surface panel that covers a surface of the base material and directs light emitted from the light source toward a passenger seat side in the cabin
Data Source
AI summary
A display unit incorporated in the housing surface of an instrument panel changes its display variously together with other display devices of the instrument panel such as a liquid crystal display, and displays information such as driving information, danger notification information and entertainment information in coordination.
