Centralized Door Access Control for Emergency Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door lock systems in schools and large companies face challenges in ensuring all doors are locked securely, particularly during emergencies like burglaries, fires, or gunshot incidents, as manual verification is time-consuming and inefficient, potentially allowing unauthorized access or delayed response.
Innovation Solution
A centralized door access control system that connects multiple door locks to a control device, allowing for simultaneous locking and unlocking based on an emergency control unit's authentication, with features for detecting emergencies like gunshots or fires to automatically lock doors and alert authorities, ensuring rapid response and enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification of door locks is used in schools and large companies, then each door can be locked individually, but it is time-consuming and inefficient to ensure all doors are locked securely, especially during emergencies
Solution Approach 1:
The patent combines multiple door locks into a single centralized control system. The control device can simultaneously control all door locks in the building, allowing simultaneous locking and unlocking operations. This merging of control functions resolves the contradiction by enabling reliable control of all doors while eliminating the time-consuming manual verification process.
Solution Approach 2:
The system performs preliminary actions by automatically locking all doors when emergency conditions are detected, such as gunfire detection or fire alarms. The control device is pre-configured to immediately lock all doors without requiring manual verification, thus ensuring reliability while saving critical response time during emergencies.
2Speed
If centralized control is implemented to lock all doors simultaneously, then response time during emergencies is reduced, but the system complexity increases
Solution Approach 1:
The control device is designed with multi-functionality to manage various door locking scenarios. It can lock all doors simultaneously, lock individual doors, unlock doors, and integrate with emergency detection systems. This universal control capability achieves fast door locking speed while consolidating control functions into a single device, thereby managing system complexity efficiently.
3Ease of operation
If door locks are controlled independently, then each door can be operated separately, but it is impossible to lock all doors immediately when a security event occurs
Solution Approach 1:
The system implements dynamic control where door locks can operate independently under normal conditions but can be simultaneously controlled when emergencies occur. The control device switches between decentralized operation mode (for flexibility) and centralized control mode (for security reliability), adapting to different operational requirements and resolving the contradiction between ease of operation and security response reliability.

AI summary
A method for controlling door access with improved safety includes connecting door locks with a control device. Through physical and electrical connection by an emergency control unit, the control device can set all door locks to a locking state and can revoke unlocking authority of all door locks. When the emergency control unit is physically disconnected from the control device, all door locks can operate independently in locking and unlocking. Furthermore, the control device is connected to at least one gunshot detection device and/or at least one fire detection device. When a gunshot event and/or a fire occurs, the door locks near the gunshot location or the fire can be rapidly locked to reduce the movement speed of the gunman and/or the spreading speed of the fire.
