Vehicle Display Device Overlapping Operation Unit Image and Selection Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle display devices, it is challenging for drivers to intuitively operate the operation unit due to difficulty in moving their line of sight between the display and the operation unit, especially when the operation unit image and selection items are displayed at different positions on a small and limited display area.
Innovation Solution
A vehicle display device with a turnable operation unit, where the display control unit displays an operation unit image mimicking the shape of the operation unit and selection items in an overlapping manner on the screen, allowing intuitive guidance and easy recognition of selection items through turning operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the operation unit image and selection items are displayed at different positions on the operation screen, then the driver can recognize the operation guide, but the display area is wasted and the items appear small on the limited display
Solution Approach 1:
The patent merges the operation unit image and selection items into a single overlapping display region. The selection items are positioned to overlap with the operation unit image, allowing both elements to occupy the same spatial area on the display. This combining approach maximizes the utilization of the limited display area while ensuring that both the operation guide and selection items remain recognizable to the driver.
2Ease of operation
If the operation unit image and selection items are displayed at different positions, then the operation guide can be provided, but the items become small and difficult to recognize on the limited display area
Solution Approach 1:
The operation unit image and selection items are merged into an overlapping display configuration, allowing both to be visible at larger sizes within the limited display area. This merging ensures that the selection items remain sufficiently large and recognizable while still providing comprehensive operation guidance to the driver.
3Area of stationary object
If the display area is used efficiently with overlapping elements, then the items can be displayed larger and more clearly, but the layout becomes more complex
Solution Approach 1:
The patent implements a merging strategy where the operation unit image and selection items are overlaid in a coordinated manner. This approach achieves efficient display area utilization and larger item presentation while managing layout complexity through systematic positioning and overlapping design.

AI summary
A vehicle display device includes a display for displaying an operation screen, an operation unit prepared separately from the display, and a display control unit for controlling display of the display according to an operation of the operation unit. The operation unit is configured to be turnable. The display control unit displays, on the operation screen, an operation unit image mimicking the shape of the operation unit, and a plurality of selection items selectable by a turning operation of the operation unit in an overlapping manner.
