Current Transducer Outputting Energy Flow Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing current transducers for alternating currents can only output the current intensity proportionally, without providing the energy flow direction, which limits their ability to control machines or processes effectively.
Innovation Solution
A current transducer that includes a current sensor to detect current intensity and an evaluation device to determine the energy flow direction, outputting the current intensity in a positive or negative range based on the determined energy flow direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only current intensity is output proportionally in known current transducers, then the output signal is simple and easy to process, but the energy flow direction information is lost and cannot control machines or processes effectively
Solution Approach 1:
The patent extends the one-dimensional current intensity output to a two-dimensional output space by introducing polarity (positive/negative output range) to represent energy flow direction. This dimensional extension allows simultaneous conveyance of both magnitude and direction information without requiring separate signal channels, thus resolving the contradiction between information completeness and signal simplicity.
2Ease of operation
If energy flow direction is indicated by pulsing LEDs or digital display as in known sensors, then visual indication is provided, but the proportional current cannot be output to control units for machine or process control
Solution Approach 1:
The patent replaces visual indication mechanisms (LEDs, digital displays) with an electrical signal-based output system that conveys energy flow direction through polarity. This substitution enables direct integration with control units while maintaining the ability to indicate energy flow direction, thus resolving the contradiction between ease of visual operation and adaptability for automated control.
3Device complexity
If current intensity is always output as positive value, then the output range is simplified, but the energy flow direction cannot be conveyed to the control unit
Solution Approach 1:
The patent applies asymmetry by using symmetric output ranges (positive and negative) to represent different energy flow directions. This asymmetric encoding scheme allows the control unit to distinguish direction based on the sign of the output value while maintaining a simple linear relationship between current intensity and output magnitude, thus resolving the contradiction between output simplicity and information completeness.

AI summary
A current transducer for measuring the current flowing through an electrical conductor includes a current sensor for detecting a current intensity through the electrical conductor and an evaluation device for evaluating measured values detected by the current sensor and determining an energy flow direction as a determined energy flow direction. The current intensity is output in a positive or negative output range of an output unit depending on the determined energy flow direction.
