Building Lock Sensor Detects External Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locking devices for buildings lack robust burglary protection, particularly against external manipulation, as they can be easily overridden by external forces without reliable detection and counteraction.
Innovation Solution
Incorporating a sensor device independent of the drive or manual actuating device to detect external forces on the locking device, which activates the drive device to maintain the locking mechanism in a secured position, using existing components like Hall sensors to generate a counterforce and prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locking devices are used, then the structure is simple and easy to operate, but the burglary protection is insufficient and the locking device can be easily overridden by external forces
Solution Approach 1:
The drive device is designed to perform dual functions: normal operation (unlocking/locking via manual actuator) and security protection (detecting external forces and activating counterforce). By making the drive device universal, the patent avoids adding separate security components, thus improving burglary protection without significantly increasing device complexity
Solution Approach 2:
The locking device monitors its own state through the sensor device and automatically activates the drive device to counteract external forces attempting to override the lock. This self-monitoring and self-protection mechanism enhances security while maintaining operational simplicity, as the system protects itself without requiring external intervention
2Reliability
If additional components are added for burglary protection, then the protection against external forces is improved, but the device complexity increases
Solution Approach 1:
The drive device is designed to perform dual functions: normal operation (unlocking/locking via manual actuator) and security protection (detecting external forces and activating counterforce). By making the drive device universal, the patent avoids adding separate security components, thus improving burglary protection without significantly increasing device complexity
Solution Approach 2:
The sensor device and drive device are integrated into the existing locking mechanism structure. The sensor device monitors the locking state and external forces, while the drive device is already present for normal operation. By merging these functions into the existing structure rather than adding separate independent systems, the patent enhances security while minimizing increases in device complexity
3Reliability
If the locking device is made more robust to resist external forces, then the burglary protection is improved, but the ease of operation may be reduced
Solution Approach 1:
The sensor device continuously monitors for external forces attempting to override the locking device. When such forces are detected, the drive device is activated to provide counterforce before the external force can successfully unlock the mechanism. This preliminary detection and counteraction maintains strong resistance to external forces while allowing normal manual operation to proceed uninterrupted during legitimate use
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances burglary protection by automatically holding the locking device in a locked position even when external forces are applied, ensuring the locking device cannot be easily unlocked, and providing continuous monitoring with an energy store for uninterrupted operation.
Implementation Method 1
a sensor device for detecting an effect on the locking device that is independent of the drive device or a manual actuating device
Implementation Method 2
the control device uses the drive device to hold the locking device in the locked position and energizes the drive device accordingly in order to apply a suitable holding force
