Grouped Locking Control for Single-Opening Access Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems often struggle to manage large numbers of locking elements efficiently, leading to security gaps and difficulties in monitoring all activated closure elements simultaneously, which can result in unauthorized access and theft.
Innovation Solution
The locking elements are divided into groups, with the control unit simultaneously opening all locking units of a selected group upon a predetermined signal, and then locking the unopened units after the first is opened, allowing unlocking only after the first element is closed and potentially after a short period, ensuring that only one element in a group can be opened at a time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all locking elements are unlocked simultaneously when a code is entered, then all authorized persons can access any locking element, but security gaps occur because it cannot be monitored which specific elements are opened and unauthorized access may occur
Solution Approach 1:
The system segments the locking elements into different groups (Group 1, Group 2, etc.) and assigns specific groups to different code levels. When a code is entered, only the corresponding group is unlocked rather than all locking elements simultaneously. This segmentation maintains operational convenience for authorized users while improving security by limiting access to specific groups only.
Solution Approach 2:
The system applies different access rights and unlocking behaviors to different groups of locking elements based on their security requirements. Each group can have customized characteristics such as simultaneous unlocking, sequential unlocking, or requiring specific codes. This local quality approach allows high-security areas to have restricted access patterns while maintaining convenience for lower-security areas.
2Productivity
If multiple locking elements are unlocked at the same time, then parallel access is enabled, but security gaps remain because all activated closure elements cannot be monitored simultaneously
Solution Approach 1:
By dividing locking elements into monitored groups, the system can track which group is accessed and which specific element within the group is opened. This segmentation enables monitoring of parallel access operations while maintaining the efficiency of simultaneous unlocking for authorized users.
Solution Approach 2:
The control unit receives feedback signals from locking elements when they are opened or closed. This feedback mechanism allows the system to monitor which specific elements are accessed even when multiple elements are unlocked simultaneously, thereby maintaining both parallel access efficiency and security monitoring capability.
3Ease of operation
If locking elements are unlocked for a prolonged period, then users have sufficient time to access elements, but security risks increase as the window for unauthorized access is extended
Solution Approach 1:
The system implements periodic or time-limited unlocking where locking elements are unlocked only for a specific duration after a valid code is entered. The control unit can automatically re-lock elements after a predetermined time period, thereby providing sufficient access time for authorized users while minimizing the security risk exposure window.
4Reliability
If individual locking elements are controlled separately, then precise access control is achieved, but device complexity increases due to the need to manage each element independently
Solution Approach 1:
The system merges the control of multiple locking elements into group-based control units. Instead of managing each locking element independently, the control unit can lock or unlock entire groups with a single command. This merging reduces device complexity while maintaining precise access control through the hierarchical group structure and code-level assignments.

AI summary
The closure elements (1-4) are provided with electrically actuated locking devices (1'-4') for closing door, window, shutter and furniture drawers. A control unit (10) is provided for opening and closing of locking units. The hedged closure elements that are secured with their respective locking units are divided into a number of groups. The signal output from code generator (C) is transmitted and the locking devices of all remaining unopened closure elements are adjusted immediately to its locking position, after opening closure elements in selected group. An independent claim is included for arrangement for securing variety of facilities.
