Depository Security Curtain and Vibration Detection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm and locking devices for depositories lack enhanced security features to prevent unauthorized access and burglary, especially when operated unattended, as they fail to effectively distinguish between legitimate deposit operations and illicit activities.
Innovation Solution
A secure depository system with a movable head door, a security curtain assembly of movable plate members, and integrated sensors that detect vibrations and unauthorized access attempts, triggering alarms and blocking access to prevent theft, while allowing authorized personnel to operate the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional alarm and locking devices are used in depositories, then basic security protection is provided, but the system cannot effectively distinguish between legitimate deposit operations and illicit activities, allowing unauthorized access attempts to go undetected
Solution Approach 1:
The security system is divided into multiple independent sensing zones (head door sensing zone, chest opening sensing zone, security curtain zones) with separate sensors and alarm triggers for each zone. This segmentation allows the system to detect different types of unauthorized access attempts independently, improving the ability to distinguish legitimate operations from illicit activities while maintaining reliable security protection.
Solution Approach 2:
The system performs preliminary detection of unauthorized access attempts before they can succeed. Sensors are positioned to detect intrusions at the head door, chest opening, and security curtain levels in advance, triggering alarms before any actual theft or unauthorized deposit can occur. This preliminary detection capability enables the system to prevent harmful factors before they manifest.
2Productivity
If the depository operates unattended to improve productivity, then customer service efficiency increases, but security monitoring capabilities are reduced, making it vulnerable to burglary attempts
Solution Approach 1:
The depository system performs self-monitoring and self-alarming functions through integrated sensors and alarm devices. The head door sensor, chest opening sensor, and security curtain sensors automatically detect unauthorized access attempts and trigger alarms without requiring human intervention. This self-service capability enables the system to maintain reliable security monitoring while operating unattended, thereby improving productivity.
Solution Approach 2:
The system incorporates continuous feedback loops where sensors constantly monitor the security status of the head door, chest opening, and security curtain. When unauthorized access is detected, the system immediately provides feedback through alarm signals and can notify monitoring centers or law enforcement. This automated feedback mechanism ensures reliable security monitoring during unattended operation, resolving the contradiction between productivity and security.
3Object-affected harmful factors
If multiple sensing zones and security curtains are added to enhance security, then detection capability improves, but the device complexity increases
Solution Approach 1:
The security system is divided into multiple independent sensing zones (head door sensing zone, chest opening sensing zone, security curtain zones) with separate sensors and alarm triggers for each zone. This segmentation allows the system to detect different types of unauthorized access attempts independently, improving the ability to distinguish legitimate operations from illicit activities while maintaining reliable security protection.
Solution Approach 2:
Each sensing zone and security curtain component serves multiple functions: detecting unauthorized access attempts, triggering localized alarms, providing detection capability, and maintaining security monitoring. The head door sensor not only detects intrusions but also works with the alarm system to provide both local and remote notification. This multi-functionality reduces the need for separate dedicated components, thereby managing device complexity while enhancing security detection capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly enhances security by preventing unauthorized access and detecting potential burglary attempts, ensuring that only authorized personnel can access the deposits and reducing the risk of theft, while allowing unattended operation of the depository.
Implementation Method 1
A vibration sensor may be attached to the depository head. The exemplary vibration sensor is operative to detect oscillating vibrations associated with sawing and/or cutting action.

AI summary
An apparatus includes a depository (10) that can receive deposit containers (20) from persons authorized to open a door lock (24). The depository includes a depository head (12) and a chest (14). A security curtain assembly (36) is movable by an actuator to block the deposit entry opening into the chest. The security curtain assembly comprises a plurality of movable plate members (52, 54, 56). At least one processor is in operative connection with sensors that can sense conditions which correspond to an attack on the depository. The at least one processor causes the actuator to close the security curtain assembly in response to a sensed attack. The processor can also cause alarms to be activated.
