Vehicle Display Device Dynamic Maintenance Information Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display devices display maintenance-related information persistently, causing user inconvenience and making it difficult to understand maintenance items and their timing in a small display space.
Innovation Solution
A vehicle display device with a first display portion showing maintenance items within a predetermined maintenance period and a second display portion showing only the nearest maintenance timing when none are due, using indices like travel distance or deterioration degree, with an operating portion to switch and clarify information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If maintenance related information pieces are displayed at all times, then users can always see maintenance status, but users feel troublesome when maintenance timing is not near
Solution Approach 1:
The display device dynamically changes its display content based on the proximity to maintenance timing. When maintenance timing is near, it displays detailed maintenance information including symbols and remaining periods. When maintenance timing is not near, it suppresses display of maintenance information to avoid user annoyance. This dynamic adaptation resolves the contradiction between maintaining information visibility and ensuring user convenience.
2Area of stationary object
If a small display portion is used for maintenance information, then space is saved, but it is difficult to display both maintenance items and remaining periods in an easy-to-understand manner
Solution Approach 1:
The display device segments maintenance information into two distinct parts: maintenance item identification (using simple symbols) and remaining period information. This segmentation allows the compact display to present both types of information separately and clearly, resolving the contradiction between saving display space and maintaining information clarity. The symbols provide quick identification while the remaining period data provides temporal context.
Solution Approach 2:
The display device applies different display qualities to different information elements within the same display portion. Maintenance items are displayed as simple symbols for quick recognition, while remaining periods are displayed as numerical data for precise information. This local differentiation of display quality allows compact presentation while maintaining clarity of both information types.
3Area of stationary object
If simple symbols are used for maintenance items, then display space is saved, but users cannot easily understand which symbol corresponds to which maintenance item
Solution Approach 1:
The display device provides feedback by displaying both the maintenance item symbol and its corresponding text label or description together. This feedback mechanism allows users to quickly associate the simple symbol with its meaning, resolving the contradiction between space saving and comprehension. The symbol provides visual recognition while the accompanying text ensures unambiguous understanding.

AI summary
Provided as display portions configured to display maintenance related information pieces about a plurality of maintenance items of a vehicle are: a first display portion configured to, when at least one of the plurality of maintenance items is in a predetermined maintenance period, display the maintenance related information piece about the maintenance item that is in the predetermined maintenance period, the predetermined maintenance period including a predetermined maintenance timing and periods before and after the predetermined maintenance timing; and a second display portion configured to, when none of the plurality of maintenance items is in the maintenance period, display only the information piece about a nearest one of the maintenance timings of the plurality of maintenance items.
