Electronic Door Apparatus Preventing Malicious Lock Deception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-service vending machines are vulnerable to malicious lock deception, where users can deceive the system into thinking the door is closed when it is actually open, leading to theft and loss for merchants.
Innovation Solution
An electronic door opening/closing apparatus that includes a turning detector and a position detector, generating turning parameter and door state signals to accurately determine the open or closed state of a side-hinged door, preventing malicious lock deception by combining these signals with a main controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single door state detector is used, then the device complexity is low, but the measurement precision of door state detection is insufficient leading to vulnerability to malicious deception
Solution Approach 1:
The patent combines two different detection methods (turning parameter detection and position detection) into a unified door state determination system. The main controller integrates signals from both the turning detector and position detector to comprehensively judge door state, merging multiple detection functions into one coordinated system that improves accuracy while managing complexity through systematic integration.
Solution Approach 2:
The main controller serves as an intermediary that receives and processes signals from both the turning detector and position detector. It mediates between the two detection systems by analyzing their respective outputs and making the final door state determination, allowing the system to benefit from multiple detection approaches without requiring direct integration between the detectors themselves.
2Reliability
If multiple detectors are combined to improve detection accuracy, then the measurement precision increases, but the device complexity increases
Solution Approach 1:
The patent merges the functions of the turning detector and position detector into a coordinated detection system where both detectors work together under the control of the main controller. This combination improves reliability by cross-validating door state through two different detection principles while the main controller manages the overall system complexity through centralized signal processing and state determination logic.

AI summary
An electronic door opening/closing apparatus and an electronic door opening/closing detection method, apparatus, and device are disclosed. The electronic door opening/closing apparatus includes: an electronic lock, disposed at a side-hinged door and configured to limit a turn of a door panel of the side-hinged door when the electronic lock is locked; a turning detector, disposed at the side-hinged door and configured to detect a turning parameter of the door panel of the side-hinged door to generate a turning parameter signal; a position detector, disposed at the side-hinged door and configured to generate a door state signal based on a position-approaching condition; and a main controller, configured to determine an open or closed state of the side-hinged door. The turning parameter signal is combined with the door state signal to accurately determine the open or closed state of the side-hinged door, and to effectively prevent malicious lock deception.
