Visual Indicator for Failed Device Identification After Power Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identifying a failed device in a computing system is challenging after power interruption, as existing methods lack a clear visual indication of the affected device.
Innovation Solution
A computing device with visual indicators interconnected with each device, where the indicators emit visible light to identify the failed device even after power interruption, using excitation devices and light-emitting layers such as phosphorescent or thermoluminescent materials that continue to emit light after power disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If power is interrupted to the computing system to repair or replace a failed device, then the failed device can be accessed for repair or replacement, but the failed device cannot be visually identified among other devices
Solution Approach 1:
The visual indicator is activated in advance before power interruption occurs. The controller energizes the visual indicator associated with the detected failed device while power is still supplied, so that the indicator is already illuminated when power is interrupted. This preliminary activation ensures the failed device remains visually identifiable during the repair process.
Solution Approach 2:
The visual indicator utilizes light emission (optical signal) to provide clear visual differentiation. The indicator changes its optical state from non-illuminated to illuminated when activated, creating a distinct visual signal that identifies the failed device among other non-illuminated devices in the computing system.
2Ease of repair
If visual indicators are activated before power interruption, then the failed device can be identified after power interruption, but energy is consumed during the identification process
Solution Approach 1:
The visual indicator is activated in advance before power interruption occurs. The controller energizes the visual indicator associated with the detected failed device while power is still supplied, so that the indicator is already illuminated when power is interrupted. This preliminary activation ensures the failed device remains visually identifiable during the repair process.
Solution Approach 2:
The visual indicator serves the dual purpose of identifying the failed device and providing guidance for repair operations. By being activated in advance, the indicator essentially serves itself by maintaining its illuminated state through the power interruption period, eliminating the need for additional energy consumption during the identification phase.
