Dual Partial Display Verification for Safety Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses for safety-relevant information lack assurance of correctness and completeness, as they do not provide a straightforward method for users to verify the accuracy and integrity of the displayed information.
Innovation Solution
A display apparatus comprising two independent partial displays arranged one behind the other in the viewing direction, where only the combined overall display represents the information correctly, allowing users to identify inaccuracies or incompleteness by comparing the two partial displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single display apparatus is used to show safety-relevant information, then the device complexity is low, but the reliability of information display is insufficient
Solution Approach 1:
The display apparatus is divided into two independent partial displays arranged one behind the other. Each partial display receives information via separate interfaces and transfer paths, allowing independent verification of displayed content. This segmentation enables users to compare the two displays to verify information accuracy, thereby resolving the contradiction between reliability and device complexity.
2Reliability
If elaborate process protection is implemented to ensure information correctness, then the reliability improves, but the ease of operation deteriorates due to restricted user control
Solution Approach 1:
The dual partial display system enables self-verification by the user without requiring complex authentication or control restrictions. Users can directly compare the two independent displays to verify information correctness, eliminating the need for elaborate process protection that would restrict user control. This resolves the contradiction by making verification simple and accessible to all users.
3Reliability
If multiple independent partial displays are used to verify information, then the reliability of information representation increases, but the device complexity increases
Solution Approach 1:
Two independent partial displays are merged into a single integrated display apparatus with a unified housing and coordinated control system. The interfaces and transfer paths are independently implemented but physically integrated, allowing information verification without requiring separate display devices. This merging approach resolves the contradiction by achieving reliability through redundancy while maintaining a compact, unified device structure.

AI summary
A display device for displaying a graphical representation of information. The display device includes a first interface for receiving the information via a first transfer path, a second interface for receiving the information via a second transfer path. A first sub-display is designed to display a first sub-region of the graphical representation using the information received by the first interface, and a second sub-display is designed to display a second sub-region of the graphical representation using the information received by the second interface. The first and second sub-display form a complete display which is configured to display the graphical representation. The first sub-display and the second sub-display are arranged one behind the other in a viewing direction.
