Superimposed Transparent Display Matrices for Visual Failure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security data displays in critical fields like nuclear, transport, and aeronautics face challenges with pixel freezing and matrix refresh faults, making real-time detection difficult and costly without complex software, and existing redundancy loop methods become increasingly complex and expensive as security data grows.
Innovation Solution
A security display device with superimposed transparent display matrices, each connected directly to the input port, allowing simultaneous display of identical information to quickly and easily detect failures visually, eliminating the need for complex software redundancy loops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If complex software redundancy loops are used to detect display failures, then detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent creates physical copies of the display information across multiple independent display matrices. Each matrix receives the same input signal and displays identical security data simultaneously. This physical redundancy allows direct visual comparison between matrices to detect failures, eliminating the need for complex software copying and comparison mechanisms.
Solution Approach 2:
The patent transitions from a single-plane display to a multi-layer transparent display structure. By stacking multiple transparent display matrices in different spatial dimensions, the system enables three-dimensional visual verification of display information. Operators can view through the transparent layers to compare data across multiple planes simultaneously, adding a dimensional aspect to failure detection.
2Reliability
If multiple display matrices are used to ensure information reliability, then display reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple display matrices into a single integrated transparent display assembly. The multiple matrices are optically aligned and physically merged into one unit that functions as a cohesive display system. This merging approach maintains reliability through redundancy while presenting a unified, manageable device structure rather than separate complex components.
Solution Approach 2:
Each display matrix in the patent serves multiple functions: it displays security data, provides a reference for failure detection, and allows visual verification when viewed through transparent layers. This multi-functionality reduces the need for separate dedicated components for each function, simplifying the overall device architecture while maintaining high reliability.
3Ease of operation
If transparent display matrices are superimposed for visual failure detection, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the display system into multiple independent transparent matrix segments that can be manufactured separately using standard transparent display technologies. Each matrix module is a discrete unit that can be produced, tested, and assembled independently. This segmentation simplifies manufacturing by breaking down the complex assembly process into manageable stages while maintaining the optical transparency needed for visual verification.
