Vehicle Display Device Ring Member Illusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Analog meters are being replaced by image display devices, which require a large display surface to be acceptable to drivers, and often provide a flat visual impression that is not preferred by those accustomed to traditional analog meters.
Innovation Solution
A vehicle display device incorporating an image display device with a ring member that surrounds a first region overlapping the display surface and a second region protruding from it, creating a visual illusion of a larger display area, similar to analog meters, by displaying indicators along the ring member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an image display device is used instead of an analog meter, then a variety of information can be displayed, but a large display surface is required which increases cost
Solution Approach 1:
The invention extends the display area from a two-dimensional flat surface to a three-dimensional curved surface by wrapping the display around a cylindrical or curved housing. This allows the display to occupy multiple dimensions of visual space, effectively increasing the display area without requiring a proportionally larger flat surface, thereby reducing cost while maintaining versatility
Solution Approach 2:
The display surface is wrapped around and integrated with the housing structure, nesting the display within the contours of the device itself. This allows the display to utilize the existing structural volume of the device, maximizing display area within a compact form factor and avoiding the need for additional space
2Loss of information
If an image display device is used instead of an analog meter, then information can be displayed digitally, but it gives a flat visual impression that is not acceptable to drivers familiar with analog meters
Solution Approach 1:
The display surface is configured to follow a curved or cylindrical contour rather than being flat, creating a three-dimensional visual field that mimics the depth and dimensionality of analog meter dials. This curvature provides a stereoscopic visual impression that is familiar and acceptable to drivers while maintaining digital information delivery
Solution Approach 2:
By extending the display into the third dimension through curvature, the invention adds depth perception and spatial dimension to the digital display. This creates a visual experience that resembles traditional analog instruments, providing familiarity to drivers while preserving the informational advantages of digital display
