Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display devices for vehicles do not effectively manage partial failures, leading to a significant reduction in the displayable area and a poor user experience.

Innovation Solution

A display control device that acquires failure region information, identifies a displayable region by omitting the failure region, reconstructs this region to display images, and outputs the reconstructed displayable region.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the display device uses a predetermined priority order to display images on non-failed displays, then the importance of information is maintained, but the displayable area is significantly reduced

Engineering Contradiction:

Improveinformation importance maintenanceVSAvoiddisplayable area

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The display region is segmented into a failure region and a displayable region based on detected failure positions. The controller then reconstructs the displayable region by rearranging display content to fit within the available non-failed areas, thereby maintaining both information importance and maximizing the usable display area.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the display device omits failed regions from display, then the failure impact is minimized, but the display area becomes extremely narrow

Engineering Contradiction:

Improvefailure impact minimizationVSAvoiddisplay area

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The controller reconstructs the displayable region by utilizing multiple dimensions - combining available display areas across different spatial arrangements and using priority-based layering to present information in a reconstructed layout that maximizes the effective display area while excluding failure regions.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Device complexity

If the display device treats any failure as a complete display failure, then the system remains simple, but the displayable region is excessively reduced

Engineering Contradiction:

Improvefailure management simplicityVSAvoiddisplayable region

Core Design Contradiction:

Device complexityVSArea of stationary object

Solution Approach 1:

Instead of treating the entire display as uniformly failed, the system applies local quality assessment by detecting specific failure positions and assigning different statuses to different regions - failed regions are excluded while non-failed regions are actively utilized. The controller reconstructs the displayable region by adapting content presentation to the local characteristics of each display area.

Inventive Principle:

Principle #3Local quality

AI summary

A display control device includes: an acquirer that acquires failure region information indicating a failure region in a display region constructed on one or more display screens that display an image; and a controller that identifies, based on the failure region information acquired by the acquirer, a displayable region obtained by omitting the failure region from the display region, reconstructs the displayable region to display the image in the displayable region identified, and outputs the displayable region reconstructed.
