Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional troubleshooting methods are used with external power supplies and monitoring equipment, then comprehensive electrical system diagnostics can be performed, but the process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent extracts the essential diagnostic functionality from complex external power supplies and monitoring equipment, consolidating it into a portable handheld device that performs anomaly detection without requiring external power sources, thereby reducing troubleshooting time while maintaining diagnostic accuracy
Solution Approach 2:
The diagnostic device is self-powered through internal battery operation, eliminating dependence on external power supplies. The device autonomously performs measurements, analyzes electrical parameters, and identifies anomalies without requiring external support equipment or personnel
2Reliability
If multiple replacement power supplies and monitoring equipment are deployed for troubleshooting, then comprehensive system testing can be conducted, but resource consumption and operational complexity increase
Solution Approach 1:
The handheld diagnostic device integrates multiple diagnostic functions into a single universal tool, including voltage measurement, current measurement, resistance measurement, and anomaly detection capabilities, replacing the need for multiple specialized power supplies and monitoring equipment while maintaining comprehensive system testing capability
Solution Approach 2:
The patent combines previously separate diagnostic functions (power supply functions, monitoring functions, measurement functions) into a single integrated handheld device, reducing equipment complexity while preserving diagnostic reliability through unified multi-functional operation
3Measurement precision
If traditional load testing procedures are performed with external power sources, then power system performance can be evaluated, but the process requires external power and support equipment
Solution Approach 1:
The diagnostic device operates autonomously using internal battery power, eliminating the need for external power sources and support equipment. The device independently performs all measurement and analysis functions, significantly simplifying the diagnostic procedure while maintaining power system analysis accuracy
Solution Approach 2:
The patent extracts the essential power system diagnostic capability from complex external power supply systems and condenses it into a portable self-powered handheld device, making the diagnostic procedure simpler and more accessible while preserving measurement precision
