Image Display Apparatus Failure Detection via Current Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in quickly determining failures in externally installed image display apparatuses, as administrators remotely cannot easily assess whether the apparatus is malfunctioning or identify fault locations.
Innovation Solution
The image display apparatus includes a controller that outputs image signals and DC powers, with a display unit comprising interfaces, a timing controller, a panel, and current detectors to detect deviations in current levels, allowing the apparatus to determine failures and transmit signals to a server for remote monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image display apparatus is installed externally, then the accessibility and visibility are improved, but the ease of determining failure and identifying fault location deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the current detector continuously monitors the current consumed by the display apparatus and transmits this information to the controller. When the current deviates from the predetermined range, the controller receives this feedback and generates a failure determination signal, enabling remote monitoring and automatic failure detection without requiring physical inspection.
Solution Approach 2:
The patent introduces an intermediary system consisting of the current detector and communication interface that mediates between the display apparatus and the remote administrator. This intermediary automatically captures failure information through current monitoring and transmits it to the administrator's terminal, eliminating the need for the administrator to physically access the externally installed apparatus.
2Adaptability or versatility
If multiple components are integrated in the display apparatus, then the functionality is improved, but the difficulty of identifying specific fault location increases
Solution Approach 1:
The patent segments the display apparatus into distinct functional components (display unit, current detector, controller, communication unit) with clearly defined boundaries and responsibilities. Each component has its own current consumption characteristics, allowing the system to identify which specific component is malfunctioning based on current deviation patterns, thus simplifying fault location in integrated systems.
