Building Security Lock Modules with Zone-Based Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for buildings face challenges in promptly controlling access and communicating threats across multiple doors, particularly in large occupant environments, where unauthorized access can lead to incidents like armed attacks due to delayed communication of active threats.
Innovation Solution
A security system with multiple lock modules, each associated with a door, that can be remotely or locally controlled through a controller to switch between unlocked and locked positions, incorporating sensors and communication technology for real-time monitoring and lockdown capabilities, including unique identifiers, door position signals, and command signals to direct lock module repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple doors are kept accessible for frequent personnel movement, then ease of operation is improved, but security reliability deteriorates due to increased unauthorized access risk
Solution Approach 1:
The security system divides the building into multiple zones with individual lock modules for each door, allowing selective locking and monitoring of specific areas without restricting access to the entire building. This enables certain doors to remain accessible while others are secured based on real-time threat assessment.
Solution Approach 2:
The system dynamically adjusts door lock states based on real-time conditions. During normal operation, doors remain unlocked for convenient access. Upon detecting a threat, the system automatically locks affected doors while leaving other areas accessible, adapting the security posture to current conditions rather than maintaining a static locked or unlocked state.
2Reliability
If lockdown is implemented for all doors during a threat, then security reliability is improved, but ease of operation deteriorates due to restricted personnel movement
Solution Approach 1:
The system applies security measures locally to specific doors or zones rather than uniformly across the entire building. When a threat is detected in one area, only the doors in that specific zone are locked, while other areas maintain normal access. This localized response preserves personnel movement freedom in unaffected areas while ensuring security where needed.
3Reliability
If real-time communication of threats throughout the building is implemented, then security reliability is improved, but device complexity increases
Solution Approach 1:
The lock modules serve multiple functions: they act as physical barriers, contain threat detection sensors, communicate with the central controller, and provide status monitoring. This multi-functionality reduces the need for separate dedicated components for each function, thereby limiting the increase in overall system complexity while achieving real-time threat communication and response capabilities.

AI summary
A security system for a building has multiple lock modules. Each lock module is associated with a particular door and has an unlocked position that allows the particular door to open and a locked position that prevents the particular door from opening. Each lock module includes a door status signal and a controller. The door status signal includes a unique identifier for the particular door associated with the lock module and a status that identifies when the lock module is in the locked position. The controller transmits the door status signal for the lock module. A lock module command signal received by at least some of the lock modules directs at least some of the lock modules to reposition to either the unlocked position or the locked position.
