Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection normality check methods are used, then connection normality can be verified, but the process requires external electric circuits and multiple checks, increasing operation complexity and time
Solution Approach 1:
The invention extracts the measurement function from the traditional external circuit requirement and integrates it into the voltmeter itself. By measuring inter-wire potential differences directly, the method eliminates the need for separate external electric circuits while maintaining verification reliability.
Solution Approach 2:
The voltmeter is designed to perform multiple functions: it can measure potential differences between different wire pairs and determine connection normality. This multi-functionality allows a single device to replace what previously required multiple separate checks and external circuits.
2Reliability
If conventional connection normality check methods are used, then connection normality can be verified, but multiple normality checks are required, increasing operation time
Solution Approach 1:
The invention merges multiple separate normality checks into a single integrated measurement process. By simultaneously measuring potential differences across both wire pairs and comparing them, the system verifies connection normality in one operation rather than requiring two separate checks.
Solution Approach 2:
The method performs preliminary measurements of potential differences at both ends of the wire pairs before making the final determination. This preliminary action allows for a comprehensive verification to be completed in a single operational sequence.
3Reliability
If conventional connection normality check methods are used, then connection normality can be verified, but external electric circuits are required, complicating the measurement process
Solution Approach 1:
The invention removes the requirement for external electric circuits by extracting the necessary measurement capability directly into the voltmeter. The device measures inter-wire potential differences without needing separate external circuits, thereby simplifying the measurement process while maintaining verification reliability.

AI summary
Connection normality check of a pair of electric wires is simplified. A circuit check device 1 that checks connection normality of a pair of electric wires L1 and L2 includes, when the pair of electric wires is connected to an exchange 2, a voltmeter 11 that measures a first inter-wire potential difference between one end of an electric wire portion p1 of the electric wire L1 and one end of an electric wire portion p2 of the electric wire L2, a voltmeter 12 that measures a second inter-wire potential difference between the other end of the electric wire portion p1 of the electric wire L1 and the other end of the electric wire portion p2 of the electric wire L2, and a determiner 13 that determines whether the measured first inter-wire potential difference agrees with the measured second inter-wire potential difference.
