Segmented Lock Rotor Assembly for Compact Barrier Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices with monolithic rotors are limited in size reduction and adaptation to specific conditions, making it difficult to optimize their size or material distribution for improved functionality and assembly.
Innovation Solution
The rotor is divided into two non-monolithic elements that can be individually optimized and assembled, allowing for a form-fitting or force-fitting connection, enabling easier adaptation and replacement, and providing a more efficient and cost-effective manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a monolithic rotor is used in the locking device, then the structure is simple and robust, but the rotor cannot be reduced in size and cannot be adapted to special conditions
Solution Approach 1:
The rotor is divided into multiple rotor elements (first rotor element and second rotor element) that are arranged axially one behind the other. These segmented rotor elements can be individually optimized for different functions and conditions, allowing the locking device to be adapted to special conditions while maintaining structural robustness through the modular design
2Volume of moving object
If a monolithic rotor is used, then manufacturing is simplified, but the rotor size cannot be reduced and customization is limited
Solution Approach 1:
The rotor is segmented into multiple rotor elements that can be manufactured separately and then assembled. This segmentation allows each rotor element to be optimized and manufactured independently, enabling size reduction and customization while actually simplifying manufacturing through modular production and assembly
Solution Approach 2:
The rotor elements are arranged axially one behind the other in a nested configuration along the rotor axis. This nesting approach allows the multiple rotor elements to occupy a compact axial space, reducing the overall rotor volume while maintaining the functionality of each individual element
3Ease of repair
If rotor elements are detachably connected, then replacement of defective elements is enabled, but the connection structure becomes more complex
Solution Approach 1:
The rotor is divided into separable rotor elements that can be independently removed and replaced. This segmentation enables easy replacement of defective rotor elements without disassembling the entire locking device, significantly improving ease of repair while the modular connection structure maintains manageable complexity
4Adaptability or versatility
If the rotor is divided into multiple rotor elements, then customization and optimization for specific functions is enabled, but the assembly complexity increases
Solution Approach 1:
The rotor is segmented into multiple rotor elements that can be individually customized for different functions and applications. Each rotor element can be optimized independently, enabling high adaptability and customization while the modular assembly process manages complexity through standardized interfaces and sequential assembly
Solution Approach 2:
The rotor elements are designed with universal features that allow them to be used in different configurations and applications. The first and second rotor elements can serve different functions while maintaining compatibility through standardized connection mechanisms, enabling customization without proportionally increasing assembly complexity

AI summary
A barrier device for a locking device is provided with a stator, with a rotor with a rotor axis and with an electromechanical actuator in the rotor. The rotor has two rotor elements, with the first rotor element and the second rotor element being arranged axially one behind the other in relation to the rotor axis. The two rotor elements are connected to each other in a rotationally fixed manner. The electromechanical actuator is arranged in one of the rotor elements. A locking device is provided with a locking device housing and the barrier device. The barrier device is received in the locking cylinder housing. In particular, the locking device includes a fastening element which is inserted from the outside into the locking device housing in order to fasten the stator to the locking device housing in a rotationally fixed manner.
