Lock Cylinder Movement Detection for Unauthorized Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locks can be unlocked using improper tools, compromising security, as they lack mechanisms to differentiate between authorized and unauthorized unlocking operations.
Innovation Solution
A lock system incorporating sensing modules and a processing unit that detect movement and generate signals to determine if the unlocking operation meets preset conditions, triggering an alarm or notification when it does not, thereby enhancing security through real-time monitoring and alerting mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional lock mechanisms are used, then the lock can be easily unlocked with proper keys, but the lock can also be unlocked via improper tools such as slender rods, hooks, and master unlocking units
Solution Approach 1:
The patent replaces the purely mechanical lock mechanism with an electronic control system that includes sensing modules, a processing unit, and an alarm unit. The sensing modules detect movements of the lock cylinder and generate sensing signals that are processed to determine whether an unlocking operation is normal or abnormal, thereby substituting mechanical security with electronic monitoring and control
Solution Approach 2:
The patent implements a feedback mechanism where sensing modules continuously monitor the lock cylinder's movements and provide sensing signals to the processing unit. The processing unit analyzes these signals to determine the nature of the unlocking operation and provides feedback by triggering the alarm unit when abnormal operations are detected, creating a closed-loop security system
2Reliability
If sensing modules and processing units are added to detect and analyze lock cylinder movements, then unauthorized unlocking can be detected, but the device complexity increases
Solution Approach 1:
The patent designs the sensing modules to perform multiple functions: detecting lock cylinder movements, generating sensing signals, and providing information to the processing unit. The processing unit itself serves multiple purposes by receiving sensing signals, determining the nature of unlocking operations, and controlling the alarm unit, thereby reducing the need for separate dedicated components for each function
