Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional high voltage phasing meters use multiple probes, then measurement capability is achieved, but device complexity and operator difficulty increase
Solution Approach 1:
The patent combines multiple probe functions into a single smart probe that integrates voltage sensing, current sensing, and processing capabilities. The single probe includes a voltage sensing element, current sensing element, and processing circuit that collectively perform measurements previously requiring separate probes, thereby reducing device complexity while maintaining measurement precision
Solution Approach 2:
The smart probe is designed as a universal measuring device that can measure multiple phase attributes (voltage, current, phase relationships) with a single unit. The probe incorporates multiple sensing elements and a processing circuit that enables it to perform various measurement functions that previously required different specialized probes, making the device more versatile and easier to operate
2Loss of information
If conventional phasing meters provide instantaneous display, then real-time measurement is achieved, but data storage and remote monitoring capabilities are lost
Solution Approach 1:
The smart probe incorporates a memory device that stores measured phase attribute data before any analysis or display occurs. This preliminary data capture ensures that all measurement information is preserved, allowing operators to review data at their convenience, perform remote monitoring, and conduct thorough analysis without the pressure of instantaneous interpretation
Solution Approach 2:
The patent introduces a communication interface as an intermediary between the measurement system and the user/remote systems. This interface enables data transmission to external devices, computers, or monitoring systems, allowing operators to access phase sequence data remotely and interpret it with the aid of specialized software or trained personnel, thereby improving ease of operation for complex data
3Measurement precision
If GPS phasing tools use base units and field units, then phase sequencing capability is achieved, but system complexity and cost increase
Solution Approach 1:
The patent extracts the complex base unit and field unit architecture from the system, replacing it with a single smart probe that contains all necessary measurement and processing capabilities integrated within one device. This eliminates the need for separate base units, field units, and their interconnections, thereby reducing system complexity while maintaining phase sequencing accuracy through the probe's internal processing circuit
