Building Door Locking System Automatic Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building door locking systems, while offering keyless entry solutions, often require active commands from authorized devices for unlocking, which can be inconvenient and lack enhanced security features.
Innovation Solution
A method that enables automatic unlocking of a motor-operated lock through the automatic reconnection of an authorized terminal device to a communication unit within a radio network, with an additional actuation signal required for secure operation, and optional time constraints for access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic reconnection of terminal device to communication unit is implemented for keyless entry, then ease of operation is improved, but security is worsened due to lack of active user confirmation
Solution Approach 1:
The terminal device automatically reconnects to the communication unit when entering the radio network range, performing the connection action in advance before the user reaches the door. This preliminary automatic connection improves ease of operation while the subsequent actuation signal requirement maintains security.
Solution Approach 2:
An actuating device (button, touch sensor, or non-contact sensor) is introduced as an intermediary element between the automatic connection and the actual door unlocking. This intermediary requires physical user presence and action at the door location, adding a security layer that prevents unauthorized automatic unlocking while maintaining convenience.
2Reliability
If active command transmission from terminal device is required for unlocking, then security is improved, but ease of operation is worsened due to additional user steps
Solution Approach 1:
The system performs the command transmission action in advance by automatically sending unlock commands when the terminal device reconnects to the communication unit. This eliminates the need for manual user commands, improving ease of operation while maintaining security through the actuation device verification.
3Reliability
If time window constraint is implemented for actuation signal, then security is improved through staged unlocking, but productivity is worsened due to access time limitations
Solution Approach 1:
The system changes the time parameter by implementing a configurable time window (e.g., 30 seconds) between terminal device connection and required actuation. This parameter adjustment enables staged security verification while allowing sufficient time for legitimate users to complete the access process.

AI summary
The invention relates to a locking system for a building door (1), comprising at least: - a locking device, e.g., a motor-driven lock (2); - a control unit (3) with a receiver for receiving an opening signal via radio; - a communication unit (5) arranged within range of the control unit (3) as a network server, which is integrated into a local radio network and which also has a transmitter for transmitting an opening signal (6) via radio to the receiver of the control unit (3); and - at least one terminal device operating as a network client, which is stored as authorized in the communication unit. This locking system is characterized in that the lock (2) can be unlocked with the control unit (3) after an authorized terminal device (7) has been registered in the communication unit (5).
