Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning is used to detect distance between terminal device and electronic lock, then distance detection is achieved, but false detection occurs leading to unintended unlocking
Solution Approach 1:
The patent introduces near-field communication as an intermediary verification mechanism between the terminal device and electronic lock. The NFC signal serves as a mediator to confirm actual proximity, validating or refuting the GPS-based distance measurement. This intermediary layer prevents false unlocking by requiring dual confirmation: both GPS distance criteria and NFC signal presence must be satisfied simultaneously.
Solution Approach 2:
The system implements feedback by using NFC signal detection to verify GPS positioning results. When GPS indicates the terminal device is within unlocking distance, the system queries the NFC unit to confirm actual proximity. The NFC verification result feeds back to validate the GPS measurement, creating a closed-loop verification system that eliminates false positives from GPS errors.
2Extent of automation
If GPS-based distance detection is used, then unlocking control can be automated, but positioning errors cause malfunction
Solution Approach 1:
Near-field communication acts as an intermediary verification layer that validates the automated GPS-based unlocking control. The NFC signal serves as a mediator to confirm whether the terminal device is truly at the required proximity, preventing automated systems from executing based on erroneous GPS data alone.
Solution Approach 2:
The system performs preliminary verification using NFC before executing the automated unlocking action. By querying the NFC unit in advance to confirm actual proximity, the system ensures that automated unlocking only occurs when both GPS positioning and NFC signal verification confirm valid conditions, preventing premature or erroneous activation.

AI summary
A lock control system includes a terminal device including circuitry, and the circuitry detects a distance between an electronic lock and the terminal device, controls unlocking of the electronic lock based on the distance, determines whether the distance is falsely detected based on a predetermined signal that the electronic lock transmits via near-field communication, and stops the control of the unlocking of the electronic lock upon determining that the distance is falsely detected.
