Electronic Locking Device with Server Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control systems for secured spaces, such as self-storage units, face challenges in securely managing access and preventing unauthorized access, particularly when physical keys can be lost, stolen, or replicated, and digital keys lack traceability and revocation mechanisms, while central managers need to enforce unilateral actions like overlocking to manage tenant compliance.
Innovation Solution
A system comprising a locking device with an actuator, lock processing unit, and communication interface, connected to a server via a network, which manages authorization data and generates control signals for locking and unlocking based on security requests, allowing secure access control and remote management of access points, including timer functionality and power management modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical keys are used for locking devices, then ease of operation is improved, but reliability deteriorates due to loss, theft, or replication
Solution Approach 1:
The patent replaces mechanical key-based locking systems with electronic locking devices that use digital authorization codes. The locking device includes an electronic lock processor and actuator that communicate with a server via network, eliminating physical keys and their associated security risks while maintaining ease of operation through electronic access methods.
2Reliability
If digital keys are used for access control, then reliability is improved, but traceability and revocation mechanisms deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where the locking device communicates with a central server to log and trace access events. The server stores authorization data and can track who accessed the secured space and when, providing complete traceability. The system can also revoke authorization codes remotely through the network connection, addressing both traceability and revocation needs.
3Reliability
If centralized server control is implemented, then reliability is improved through secure authorization management, but device complexity increases
Solution Approach 1:
The patent segments the access control system into distinct functional components: a centralized server for authorization management, a locking device with lock processor and actuator for local control, and network communication interfaces for coordination. This segmentation allows the complex authorization logic to be centralized while keeping the local locking mechanism relatively simple and modular.
4Productivity
If remote access control is enabled, then productivity is improved through efficient management, but security risks increase from potential unauthorized access
Solution Approach 1:
The patent introduces a centralized server as an intermediary between users and the locking device. The server verifies authorization codes, manages access permissions, and logs all access attempts. This intermediary layer enables remote access control and efficient management while maintaining security through centralized authorization verification and audit trails.

AI summary
Systems and methods for controlling access to a secured space are disclosed. The system includes a locking device having a body having a rotatable locking cam having a locked paddle and an unlocked paddle. The cam is rotatable between a first position and a second position. The body also has a locking pin and a power supply for supplying electrical power to circuit components of the locking device. The locking device also includes a shackle having two arms. One of the two arms has a groove in a bottom portion thereof configured to engage with the locking pin when the shackle is in a closed position. In the first position, the locked paddle of the rotatable locking cam engages the locking pin in the groove. In the second position, the locked paddle of the rotatable locking cam is disengaged from the locking pin.
