Access Control Communication Device for Real-Time Key Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems face challenges in efficiently updating access rights across lock devices, particularly when key devices are lost, due to the cumbersome nature of current key update devices, leading to security compromises from delayed propagation of updates.
Innovation Solution
An access control communication device equipped with a short distance radio communication module and a cellular radio communication module, allowing for secure and efficient communication of access rights between key devices and access control devices over a cellular network, enabling real-time updates and improved security through a compact, user-carried device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated key update devices connected to laptop computers are used to update access rights, then updated access rights can be provided to key devices, but the key update devices are large and cumbersome, leading to infrequent updates and compromised security
Solution Approach 1:
The patent replaces the mechanical/cumbersome dedicated key update devices connected to laptops with a mobile communication terminal that uses wireless communication (cellular and short-distance radio) to transmit access rights data. This substitution eliminates the physical bulk and operational complexity of previous update devices while maintaining the ability to provide updated access rights to key devices.
2Reliability
If dedicated key update devices are used to update access rights, then access rights can be updated, but significant time passes between operator updating and propagation to lock devices, compromising security
Solution Approach 1:
The patent enables preliminary action by allowing the mobile communication terminal to store and prepare access rights data in advance. When a key device is present and authenticated, the updated access rights can be immediately transmitted without waiting for operator intervention or physical device connection, significantly reducing the time delay in propagation.
Solution Approach 2:
The mobile communication terminal serves as an intermediary between the access control system and key devices. It receives, stores, and transmits access rights data wirelessly, enabling rapid propagation of security updates without requiring direct connection between the operator's laptop and each key device, thus eliminating significant time delays.
3Ease of manufacture
If lock devices are installed without power supply to simplify installation, then installation is easier, but the devices cannot independently communicate access rights updates
Solution Approach 1:
The mobile communication terminal acts as an intermediary that provides communication capabilities to powerless lock devices. It wirelessly transmits access rights data to key devices, which then communicate with the lock devices, enabling update propagation without requiring the lock devices themselves to have power supplies or independent communication modules.
