Solution Overview
Problem
Existing locking devices for doors, compartments, and flaps with rotary knobs and electronic components face challenges in easy battery replacement, as current designs do not facilitate straightforward access to batteries for maintenance or replacement.
Innovation Solution
A locking device with a stator and rotor configuration, where the handle is secured via a clamping spring that includes a magnet for easy disassembly, allowing external magnetic influence to release the clamping connection, enabling simple access to internal batteries for replacement, using a dismantling tool with a magnet and markings for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the handle is securely fixed to the rotor using a clamping connection, then the torque transmission and operational reliability are improved, but the ease of battery replacement deteriorates
Solution Approach 1:
A magnet is introduced as an intermediary element within the clamping spring to enable remote actuation. The magnet interacts with an external magnet through magnetic fields, allowing the clamping connection to be released without direct mechanical intervention, thus facilitating easy battery replacement while maintaining secure operation
Solution Approach 2:
The manual disassembly process is replaced by a magnetic actuation system. Instead of requiring mechanical tools or force to release the clamping spring, an external magnet creates magnetic forces that automatically release the clamping connection, simplifying the battery replacement process
2Stability of the object's composition
If a secure clamping connection is used to hold the handle, then the structural stability is improved, but the disassembly complexity increases
Solution Approach 1:
The magnet embedded in the clamping spring serves as a mediator that translates external magnetic influence into mechanical release action. This intermediary mechanism allows the stable clamping connection to be easily released through simple magnetic actuation, reducing disassembly complexity
Solution Approach 2:
The magnetic field strength parameter is used to control the clamping force. By changing the magnetic field strength through external magnet positioning, the clamping connection transitions from a high-force secured state to a released state, enabling simple disassembly without complex mechanical operations
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
Enables easy assembly, disassembly, and battery replacement without requiring extensive tools or expertise, ensuring the locking device remains functional and reduces maintenance time.
Implementation Method 1
The magnet attached to the clamping spring is moved by magnetic influence (attraction, repulsion). Such movement of the magnet either changes the position of the entire clamping spring or changes the relative position of individual sections of the clamping spring.

AI summary
The invention relates to a locking device for doors, compartments, and flaps. The stator is equipped with a battery-operated motor and an electronic control unit which acts on the motor. A handle (20) is connected to the rotor (30) so as to transmit a torque and is held on the rotor (30) by a clamping spring (50). The clamping spring (50) has a receiving area for a magnet (60). The process of replacing the battery for the motor is easily facilitated in that the clamping connection between the handle (20) and the rotor (30) is triggered by an external influence on the magnet (60) (Fig. 1).
