Mechatronic Locking Apparatus Dual Communication Path Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechatronic locking devices lack enhanced security and efficient data management capabilities, particularly in networked systems, where centralized control and secure user identification are necessary but not fully realized.
Innovation Solution
The locking device employs dual communication paths: an electrical contact for power supply and data transmission, and RFID for contactless data exchange, enabling bidirectional communication, encrypted data storage, and integrated identification/authentication mechanisms, with a control circuit that manages access data centrally via both paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication path via electrical contact is used, then the device structure is simple, but security and data management capabilities are insufficient
Solution Approach 1:
The communication system is segmented into two independent paths: a first communication path via electrical contact for power supply and data transmission, and a second communication path via RFID for contactless data exchange. This segmentation allows each path to serve specific functions, enhancing overall security while maintaining manageable complexity through functional separation.
Solution Approach 2:
The control circuit acts as an intermediary that manages both communication paths, the battery serves as an intermediary power source for the first path, and the RFID system serves as an intermediary for contactless communication. These intermediaries enable secure data exchange through multiple channels without requiring direct physical connection for all operations.
2Reliability
If power supply is integrated into the key via battery, then communication reliability is improved, but key complexity and manufacturing cost increase
Solution Approach 1:
The battery, first communication path electrical contact, and control circuit are merged into an integrated key assembly. This combining of power supply and communication functions into a single unit simplifies the overall system architecture while ensuring reliable powered communication when the key is inserted into the lock cylinder.
3Reliability
If centralized data management is implemented, then security control is enhanced, but system complexity and network requirements increase
Solution Approach 1:
The control circuit in the lock cylinder receives data from both communication paths, processes it through a centralized data management system, and provides feedback by determining whether to unlock the rotor. This feedback mechanism ensures centralized security control while maintaining a relatively simple operational structure through automated decision-making based on received data.

AI summary
The mechatronic locking apparatus comprises a control circuit (4), from which information signals can be transmitted to a control circuit (6) of the lock cylinder (2) using a first communication path (5). A security key (3) has at least one second communication path (7) for storing and/or processing access data. The two communication paths (5, 7) are connected to said control circuit (4) of the security key (3). The first communication path (5) preferably uses an electrical contact in the lock cylinder (2). The second communication path (7) comprises a transponder (8). The first communication path (5) may also be used for power supply purposes.
