Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server power supply systems lack the capability to quickly and accurately identify which power supply unit is causing a failure among multiple types, leading to difficulties in maintenance and troubleshooting.
Innovation Solution
A power supply device with multiple power supply units, monitoring units, latching units, and a positioning module that outputs signals to isolate and identify the failing unit, utilizing logic gates and signal processing to determine the first power failure and alert maintenance personnel through visual or auditory indicators.

Engineering Contradiction Analysis
1Reliability
If multiple power supply units are used to supply power to server system, then power supply reliability is improved, but difficulty in detecting and measuring which unit fails first increases
Solution Approach 1:
The power supply system is segmented into multiple independently monitored units, each with its own monitoring unit and latching unit. This segmentation allows individual tracking of each power supply unit's status, enabling precise identification of which specific unit fails first among multiple units.
Solution Approach 2:
The system implements feedback through monitoring units that continuously detect the status of each power supply unit and provide signals to latching units. When a power supply unit fails, the monitoring unit generates a power failure signal that is latched and fed back to the positioning module, creating a closed-loop feedback system that automatically identifies and reports the failing unit.
2Measurement precision
If monitoring and positioning systems are added to identify power supply failures, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Latching units are pre-configured to immediately capture and hold power failure signals as soon as they occur. This preliminary action ensures that the first power supply unit to fail is recorded before any subsequent failures occur, enabling precise identification of the primary failure source without requiring complex analysis of failure sequences.
Solution Approach 2:
The system adds a temporal dimension to power supply monitoring by using latching units that capture the timing of failures. The positioning module utilizes the sequence of latching signals in time to determine which power supply unit failed first, transforming a spatial problem (identifying which unit) into a temporal problem (identifying the order of failures).

AI summary
A power supply device including a working power supply module with a plurality of power supply units; a plurality of monitoring units outputting a power failure signal when the corresponding power supply unit is in a power failure; a plurality of latching units respectively corresponding to the plurality of monitoring units one to one, receiving the power failure signal and a disabling signal, and outputting a latching signal when the power failure signal is received but the disabling signal is not received; and a positioning module used for receiving the latching signal and outputting a disabling signal when the positioning module receives a first latching signal output by one latching unit to disable other latching units, so as to enable the positioning module to position the latching unit which firstly outputs the latching signal to position the corresponding power supply unit which is firstly in a power failure.
