Motor Vehicle Display Key Assignment Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In motor vehicles, the limited display area poses a challenge for efficiently displaying information about the assignments of functions to freely assignable operating keys, as existing methods often require additional space for detailed descriptions, which can disrupt the spatial correspondence and clarity of key assignments.
Innovation Solution
A method where brief descriptions of operating keys are displayed side-by-side in an edge region of the display unit, and upon selection, the detailed description covers the entire screen area used for the brief description, potentially overlapping with adjacent keys, allowing for efficient use of display space without requiring additional area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If detailed descriptions are displayed for each operating key, then information completeness is improved, but display area requirements increase
Solution Approach 1:
The display is segmented into two hierarchical levels: a first level showing brief descriptions of all operating keys simultaneously, and a second level showing detailed descriptions of selected keys. This segmentation allows comprehensive information to be available without requiring all details to be displayed at once, thus maintaining information completeness while controlling display area usage.
Solution Approach 2:
The display dynamically transitions between showing brief descriptions of multiple keys and detailed descriptions of selected keys. When a key is selected, the display shifts from the first level (brief descriptions) to the second level (detailed description), optimizing the use of display area based on user interaction and information needs.
2Ease of operation
If brief descriptions of all operating keys are displayed side-by-side, then overview capability is improved, but detailed information display is limited
Solution Approach 1:
The information hierarchy is segmented into brief descriptions for overview and detailed descriptions for in-depth information. The brief descriptions are displayed side-by-side in the first level to provide overview capability, while detailed descriptions are reserved for the second level when keys are selected, ensuring both overview and detail needs are met without conflict.
Solution Approach 2:
Brief descriptions are displayed in advance for all operating keys to provide immediate overview capability. When a user selects a key, the detailed description is then provided in the second level. This preliminary display of brief descriptions allows users to quickly scan and select keys of interest without being overwhelmed by detailed information.

AI summary
In a method for displaying information relating to the assignments of functions to a group of freely assignable operating keys in a motor vehicle, a first display step outputs for each operating key of the group a brief description of the respective function assignment, and a second display step outputs for a single selected operating key of the group a more detailed description. In the first display step, the brief descriptions of all operating keys of the group are output side-by-side into screen areas, which essentially are adjacent to each other, in an edge region of a display unit of the motor vehicle. In the second display step, the more detailed description is output into the same edge region of the same display unit such that the more detailed description covers the entire screen area of the brief description of the selected operating key, and the more detailed description at least partially covers the screen area of the brief description of at least one additional operating key.
