Solution Overview
Problem
Existing locking devices for cabinets, boxes, or compartments often struggle to provide high resistance against unauthorized attacks, particularly in terms of absorbing high torques.
Innovation Solution
A locking device with a pot-like housing serving as the stator, a rotor connected to a locking element, and a coupling arrangement featuring a manually or electronically adjustable actuator, a movable driver, and a locking member that prevents unauthorized rotation of the rotor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical lock is equipped to prevent unauthorized opening, then security is improved, but the device becomes more complex and requires additional components
Solution Approach 1:
The patent combines the locking mechanism and actuator into a single integrated unit where the actuator serves dual purposes: it directly actuates the locking element and simultaneously engages with the driver to enable rotor rotation. This merging eliminates separate components and reduces overall device complexity while maintaining security functionality
Solution Approach 2:
The actuator is designed with multi-functionality, serving both as a direct locking mechanism actuator and as a coupling element that engages with the driver. This single component performs multiple functions, reducing the need for additional parts and simplifying the overall device structure
2Strength
If the locking element is made resistant to high torques, then unauthorized attacks are prevented, but the ease of operation for authorized users may be reduced
Solution Approach 1:
The locking mechanism transitions from a static blocked state to a dynamic unlocked state through rotor rotation. The coupling arrangement dynamically engages and disengages based on rotor position, allowing the system to adapt between high-strength locking mode and easy operation mode seamlessly
Solution Approach 2:
The driver acts as an intermediary mechanism that mediates between the actuator and the locking element. It translates the actuator's linear motion into rotational motion of the rotor, which then operates the locking element, providing mechanical advantage and ease of operation while maintaining high torque resistance
3Reliability
If a coupling arrangement is added to control rotor rotation, then unauthorized rotation is prevented, but the device complexity increases
Solution Approach 1:
The coupling arrangement merges the actuator and driver into an integrated mechanism where the actuator's positioning directly controls the driver's engagement with the rotor. This combining of functions into fewer components reduces overall complexity while maintaining protection against unauthorized rotation
Solution Approach 2:
The driver is preliminarily positioned to engage with the actuator before rotor rotation occurs. This preliminary engagement ensures that unauthorized rotation is blocked in advance, while authorized operation seamlessly transitions through the pre-positioned coupling mechanism without requiring additional complex control systems
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
The locking device effectively absorbs high torques during unauthorized attempts, maintaining high security standards while allowing authorized access through controlled rotation of the rotor.
Implementation Method 1
In the blocking position, the blocking member is pressed into this depression by a spring force, and preferably less than one third of the blocking member is located in this depression. In this case, the spring force is exerted by a spring which exerts a spring force radially relative to the rotor axis.

AI summary
The invention relates to an improved locking device for the closure of doors on cabinets, of boxes or compartments, which offers high resistance to unauthorized attack and, in particular, can take up high torques. For this purpose, use is made of a coupling arrangement having a manually or electronically movable actuating member, a driver (40), which interacts with the actuating member, and a blocking member (50). The blocking member (50) has the form of a cylinder, the cylinder axis of which runs parallel to the rotor axis (19). The blocking member (50) in its blocking position engages in a depression (17) on the outer side of the rotor (10) or in a depression (22) on the inner side of the wall (21) of the stator (20) and is held in this blocking position by spring force.
