Locking Device Segmented Control for Anti-Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices lack sufficient security against manipulation attempts, as the actuator unit can be directly accessed and controlled, allowing unauthorized access.
Innovation Solution
A secondary control device is integrated within the lock cylinder, connected to a primary control device via electrical means, with a secondary control device designed to exchange data securely and control the actuator unit, while the primary control device handles identification and authorization checks, using RFID or biometric data for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the actuator unit is directly accessible from the actuating element, then the operation is simple and direct, but the security against manipulation is insufficient
Solution Approach 1:
The control device is divided into two separate units: a primary control device located in the actuating element and a secondary control device located in the lock cylinder. This segmentation allows the actuator unit to be protected within the cylinder while maintaining operational functionality through coordinated control between the two devices.
Solution Approach 2:
An electrical connection means (cable) acts as an intermediary between the primary and secondary control devices, transmitting control signals and data while physically separating the control functions. This intermediary connection enables secure communication while maintaining the protective barrier of the lock cylinder.
2Reliability
If the primary control device is removed from the lock cylinder, then the actuator unit becomes accessible for manipulation, but the operation becomes simpler
Solution Approach 1:
The primary control device is extracted from the lock cylinder and placed in the actuating element, while the secondary control device remains inside the cylinder. This extraction protects the actuator unit by keeping the main control functionality outside the cylinder, yet the system remains operational through the secondary device's ability to receive and execute control signals.
Solution Approach 2:
The control function is distributed across two spatial dimensions: the primary control device in the actuating element (external dimension) and the secondary control device in the lock cylinder (internal dimension). This dimensional distribution allows manipulation protection while maintaining operational access through signal transmission between dimensions.
3Reliability
If data exchange between control devices is implemented, then the security through authorization checks is improved, but the device complexity increases
Solution Approach 1:
The control devices exchange data and control signals through the electrical connection means, creating a feedback loop that enables authorization checks and coordinated operation. The secondary control device receives control signals from the primary device and executes them while providing status information back through the data exchange channel.

AI summary
The device (100) has an operating member (120) i.e. turning knob, for actuating a closing cylinder (110) i.e. DINprofile cylinder, which comprises an actuator unit (114) for actuating a closing member (112). The operating member has a primary control device (122) for controlling the actuator unit. The closing cylinder comprises a drilling guard unit (116) at an end region (110a) that faces the operating member. An electrical connection unit (130) i.e. multi-wired cable, connects the primary control device with the actuator unit using the drilling guard unit. An independent claim is also included for a method for operating a closing device.
