Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If on-site measurement with oscilloscope is used to locate faults, then measurement precision is improved, but loss of time and productivity deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-deploying data collection channels and monitoring systems within the server rack power supply unit. Voltage, current, and temperature data are continuously collected and stored in memory before faults occur, so when a fault happens, the data is already available for immediate analysis without requiring on-site measurement equipment.
Solution Approach 2:
The patent creates a digital copy of the electrical signal waveforms by converting analog voltage and current signals into digital data through data collection channels. This digital copy is stored in memory and can be remotely accessed and analyzed, replacing the need for physical oscilloscope measurements while maintaining measurement precision.
2Measurement precision
If engineers go to site for fault measurement, then measurement accuracy is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The system applies self-service by automatically collecting, storing, and managing fault-related data through integrated data collection channels and memory units within the power supply. The system autonomously captures voltage, current, and temperature data and makes it available for analysis, eliminating the need for engineers to manually set up measurement equipment at the site.
Solution Approach 2:
The patent introduces an intermediary data processing system that includes data collection channels, memory storage, and remote access capabilities. This intermediary layer between the physical fault and the analyst allows remote diagnosis while maintaining measurement accuracy, simplifying the operation for engineers who can analyze data without being physically present at the fault location.
3Productivity
If remote monitoring is implemented, then productivity is improved, but measurement precision may deteriorate
Solution Approach 1:
The patent creates high-fidelity digital copies of analog electrical signals through data collection channels that convert voltage, current, and temperature data into digital format. These digital copies are stored in memory and transmitted for remote analysis, preserving measurement precision while enabling remote access and improving diagnostic productivity.
Solution Approach 2:
The patent replaces the mechanical approach of physical oscilloscope measurement with an electronic/digital system. Data collection channels continuously capture electrical parameters and store them in memory, allowing remote access without mechanical intervention. This substitution maintains measurement precision while significantly improving productivity by eliminating the need for on-site measurement.

AI summary
A device fault diagnosis system includes: a data sampling chip, a first memory, and a processor, wherein the data sampling chip includes a plurality of data collection channels; the data sampling chip collects working data of monitoring positions electrically connected to respective data collection channels, in a device to be monitored, through the respective data collection channels; when determining that the working data of a first monitoring position is abnormal, generates an interrupt signal corresponding to the first monitoring position; and transmits the interrupt signal to the first memory; the first memory stores the working data of the first monitoring position within a preset time period starting from a moment when the interrupt signal is received, into a preset position; and the processor periodically polls the data sampling chip, and after determining that the data sampling chip generates the interrupt signal, reads the working data from the preset position.
