Solution Overview
Problem
Existing methods for examining electrical properties of objects using electric fields face difficulties in obtaining sufficient information due to dedicated electrode functionalities, limiting the accuracy and completeness of property identification.
Innovation Solution
A method where electrodes can alternate between transmitter and receiver roles within the same scanning cycle, allowing for enhanced data collection without significant modifications to the apparatus, by energizing and monitoring electrodes sequentially during strobing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If electrodes are dedicated as transmitter or receiver electrodes, then the apparatus structure is simple, but the information obtained is insufficient
Solution Approach 1:
Each electrode is configured to perform both transmitter and receiver functions by switching roles during different strobing operations within a scanning cycle. The first electrode acts as transmitter during first strobing and as receiver during second strobing, while the second electrode does the opposite, enabling comprehensive electrical property measurement without adding more electrodes
Solution Approach 2:
The electrode functions are made dynamic rather than static. The system switches electrode roles in real-time during the scanning cycle, with timing control circuitry managing the alternation between transmitter and receiver modes to maximize information extraction from the same physical electrodes
2Measurement precision
If electrodes alternate roles during strobing operations, then comprehensive information is obtained, but the control complexity increases
Solution Approach 1:
The system employs periodic strobing operations with alternating electrode roles within each scanning cycle. This regular, repeating pattern of energizing and monitoring phases provides structured timing that simplifies control logic while enabling comprehensive data collection from multiple electrode configurations
Solution Approach 2:
The system monitors output signals from electrodes during both transmitter and receiver phases, using this feedback information to characterize electrical properties of the object. The feedback from multiple measurement configurations enables accurate property identification while the control system adapts to optimize the examination process

AI summary
The electrical properties of objects are examined, using electric fields. An object is arranged on an apparatus having a first electrode (201) and a second electrode (202). The first electrode is energised during a first strobing operation of a scanning-cycle and the second electrode is monitored during this first strobing operation. Thereafter, during a second strobing operation, the second electrode is energised and the first electrode is monitored.
