Vehicle Display Ring Positioning and Illumination Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display devices lack flexibility in layout and appearance, as second indicators can only move within a limited range without overlapping, restricting the overall display change and causing degradation in appearance when virtual and real images are misaligned.
Innovation Solution
A vehicle display device with a moving mechanism that allows the first and second ring portions to change positions, enabling a 'one-ring' or 'two-ring' configuration, and using illumination to make the ring portions appear aligned, even when misaligned, thereby enhancing design and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the second indicators are moved to overlap with the first indicator, then the layout flexibility is improved, but the misalignment between virtual and real images degrades the appearance
Solution Approach 1:
The patent uses a camera to capture the physical indicator layout and displays a virtual image copy on a display unit. This virtual copy can be positioned and scaled independently from the physical indicators, allowing layout flexibility without compromising the appearance of alignment. The virtual image serves as a flexible representation that can adapt to different layouts while maintaining visual consistency.
Solution Approach 2:
The display unit acts as an intermediary between the physical indicators and the viewer. It can display virtual images that compensate for misalignment by adjusting position, size, and orientation. This intermediary layer allows the system to achieve the desired visual appearance even when physical components are misaligned, resolving the contradiction between layout flexibility and alignment precision.
2Adaptability or versatility
If the second indicators are moved freely, then the display configuration changes significantly, but the misalignment becomes visible and degrades appearance
Solution Approach 1:
The virtual image created by the camera and display unit can be independently positioned and scaled to match the desired display configuration. This allows the system to achieve significant display changes while maintaining visual alignment through the virtual representation, rather than being constrained by physical component alignment.
Solution Approach 2:
The system changes parameters of the virtual image (position, size, orientation) independently of the physical indicators. By adjusting these parameters, the display can adapt to different configurations while maintaining the appearance of proper alignment, resolving the contradiction between configuration flexibility and visual alignment.
3Adaptability or versatility
If the ring portions are moved to overlap, then layout flexibility increases, but the misalignment degradation occurs when they are substantially misaligned
Solution Approach 1:
The camera captures the physical ring portions and creates virtual representations on the display unit. These virtual copies can be overlaid and positioned flexibly without the constraints of physical alignment. The system can display multiple ring portions in overlapping configurations while maintaining the appearance of precise alignment through the virtual representation.
Solution Approach 2:
The display unit serves as an intermediary that can adjust the visual appearance of ring portions independently of their physical positions. By manipulating the virtual images of the rings, the system achieves layout flexibility while compensating for any misalignment, ensuring that the final visual output maintains high alignment precision.

AI summary
A display device for a vehicle includes: a ring portion and a moving mechanism to display various vehicle information associated with a travel of the vehicle for a viewer within a display area. The ring portion forms an outer periphery of an indicator indicating at least one vehicle information of the various vehicle information, and is visually recognized as a virtual image within the display area. The moving mechanism is able to move a position of the ring portion.
