Locking System Communication Unit Authorization Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building door locking systems face limitations in user administration, particularly in managing and updating access authorizations for both wireless network-capable end devices and conventional radio access control devices, which are often stored and checked in the controller, limiting flexibility and functionality.
Innovation Solution
The access authorizations for radio access control devices are stored and managed in a communication unit that acts as a network server, allowing it to receive and transmit radio signals, enabling the communication unit to handle authorization checks and send opening signals independently, thus separating the management of terminals and radio access control devices and providing a standardized interface for various devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access authorizations are stored and managed in the controller, then the locking system can verify authorizations, but the flexibility and functionality for managing user authorizations are limited
Solution Approach 1:
The patent segments the authorization management function by separating it from the controller and placing it in the communication unit. The communication unit now stores and manages access authorizations independently, while the controller focuses on executing locking operations. This segmentation enables flexible user management through the communication unit without overloading the controller, resolving the contradiction between management flexibility and system complexity.
Solution Approach 2:
The communication unit acts as an intermediary between the wireless access control devices and the controller. It receives radio signals from access control devices, verifies authorizations against stored data, and then communicates with the controller to execute locking operations. This intermediary role enables flexible authorization management while keeping the controller's functionality focused and simple.
2Ease of operation
If the communication unit is integrated into the locking system for network communication, then remote access is enabled, but the management of multiple devices and users becomes complex
Solution Approach 1:
The patent merges the functions of network communication and authorization management into the communication unit. By combining the Wi-Fi interface and the database for storing access authorizations in one component, the system simplifies device management. Multiple wireless devices can be managed through a single communication unit without requiring separate programming in the controller, making the system easier to operate while maintaining centralized control.
3Reliability
If wireless access control devices are programmed into the controller, then authorization verification is possible, but updating and modifying authorizations becomes difficult
Solution Approach 1:
The patent extracts the authorization data storage and management function from the controller and places it in the communication unit. The controller retains the reliable authorization verification logic, while the communication unit handles the storage and updating of authorization data. This extraction allows easy updates and modifications of authorizations through the communication unit's interface without affecting the controller's verified reliability.
Solution Approach 2:
The system becomes dynamic in terms of authorization management. The communication unit can dynamically add, remove, or modify access authorizations in its database without requiring reprogramming of the controller. This dynamic capability maintains reliable verification through the controller while enabling flexible updates, resolving the contradiction between reliability and ease of modification.
