Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional RF card swiping is used, then the system is simple to operate, but the reliability of successful transaction is low due to mis-operation or machine failure
Solution Approach 1:
The patent implements feedback mechanisms where the electronic device captures motion data via sensors and sound data via microphone during card swiping, then compares these against reference data to determine success or failure, providing users with immediate feedback on whether the swipe was successful
Solution Approach 2:
The patent replaces traditional mechanical card swiping detection with electronic sensing systems including motion sensors that detect device movement patterns and acoustic sensors that capture sound characteristics, substituting mechanical interaction with electronic field-based detection
2Measurement precision
If motion and sound detection are added to verify card swiping, then the measurement precision of swipe success is improved, but the device complexity increases
Solution Approach 1:
The patent makes the electronic device itself serve multiple functions: it acts as both the cardholder and the detection device, using the device's existing sensors (motion sensors, microphone) for both other purposes and for card swiping verification, eliminating the need for separate dedicated detection hardware
Solution Approach 2:
The electronic device performs self-detection by using its own built-in sensors to monitor its own motion and the surrounding sound environment during card swiping, comparing the captured data against stored reference patterns to autonomously determine swipe success

AI summary
A method for detecting swiping of a card applicable in an electronic device controls a motion detecting device to acquire motion data of the electronic device, controls a distance detecting device to detect a distance between the electronic device and a card, determining whether the motion data is within at least one predetermined range of motion data, determines whether the detected distance is less than or equal to a predetermined value; controls the recording device to record sounds at the proximity of the electronic device if the motion data is within the at least one predetermined range of motion data and the detected distance is less than or equal to the predetermined value, determining whether the recorded sounds are the same as responsive sounds of card-swiping; and determines that swiping of the card is successful if the recorded sounds are the same as the responsive sounds of card-swiping.
