Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive connections are used to transmit voltage data from measuring device to display device, then voltage measurement can be performed, but user safety is compromised due to electrical shock hazard
Solution Approach 1:
The patent replaces the mechanical conductive cable connection with a wireless communication system. The measuring device transmits voltage data wirelessly to the display device using wireless communication protocols, eliminating the physical cable that conducted high voltage and created safety hazards. This substitution maintains measurement functionality while removing the electrical shock risk associated with conductive connections.
2Ease of operation
If conductive cabling is used for voltage measurement, then measurement can be performed, but handling and mobility become cumbersome
Solution Approach 1:
The patent extracts the conductive cable from the measurement system, separating the data transmission function from the physical connection. The measuring device now communicates wirelessly with the display device, allowing the measuring device to be moved freely without being constrained by cable length or requiring cable management. This extraction of the cable completely resolves the handling convenience issue.
3Adaptability or versatility
If multiple measuring devices are used for multipoint measurements, then comprehensive voltage data can be collected, but system complexity and cabling requirements increase significantly
Solution Approach 1:
The patent implements a universal wireless communication interface that allows multiple measuring devices to connect to a single display device without requiring separate cables for each device. The display device can receive and process data from multiple measuring devices simultaneously through wireless communication, providing multipoint measurement capability while eliminating the need for multiple cables and complex cabling arrangements.

AI summary
A voltage measurement system has a voltage measuring device connected to a device under test by a voltage divider to drop high voltages (e.g., peaking at or above 100 kilovolts) at a measurement point to lower levels for processing by a voltage measurement and wireless printed circuit board. The voltage measuring device communicates raw measurement data wirelessly (e.g., via Bluetooth®) to a remote device such as a mobile phone, laptop or portable meter head having a display and processing device programmed to calculate voltage measurements such has absolute average (ABS AVG), AC root mean square (RMS), +/- peak voltage, and AC or DC coupling. The remote device can wirelessly communicate with multiple voltage measuring devices to capture raw measurement data therefrom for voltage measurement applications with multiple measurement points (e.g., three-phase measurement, and transformer testing).
