Security Container Monitor With Lock Confirmation Alerts

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Human errors in securing vault doors, secure space exterior doors, and safe doors or drawers often occur due to forgetfulness or miscommunication, leading to unsecured containers, which existing security systems cannot effectively address without costly retrofits or modifications.

Innovation Solution

A monitor system for security containers that includes a sensor to detect open or closed positions, an audible alarm, and a user input device to confirm locking, ensuring the container is secured, with optional data logging and snooze features to prevent unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If smart lock hardware with sensors is integrated into existing locking systems, then security monitoring capability is improved, but device complexity and cost increase significantly

Engineering Contradiction:

Improvesecurity monitoring capabilityVSAvoidlocking system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the monitoring function into separate components: existing locking mechanisms remain unchanged while a独立的 monitor assembly with sensors and alarms is added. This segmentation allows security monitoring to be improved without modifying or complicating the original locking system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A monitor assembly acts as an intermediary between the locking mechanism and the user. It senses the locked state through a sensor and communicates this information through audible alarms and user input devices, bridging the gap between mechanical locking and digital monitoring without requiring direct integration.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If retroactive modifications are made to existing safes and security containers, then security awareness and monitoring are improved, but manufacturing cost and installation labor increase

Engineering Contradiction:

Improvesecurity awarenessVSAvoidretrofit cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The monitoring functionality is extracted from the locking mechanism itself and implemented as a separate, attachable monitor assembly. This allows the monitoring system to be added to existing containers without modifying the original structure, reducing retrofit costs and simplifying installation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The monitor assembly uses inexpensive, readily available components such as magnetic sensors, audible alarms, and simple input devices. These components can be easily manufactured and installed, making the retrofit process cost-effective while providing reliable security monitoring.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If manual dial spinning confirmation is required, then security control is improved, but ease of operation decreases

Engineering Contradiction:

Improvesecurity controlVSAvoidlocking operation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system provides immediate feedback through an audible alarm when the monitor detects that the container is locked. This feedback confirms to the user that the locking action was successful, eliminating the need for manual dial spinning confirmation while maintaining security control.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The monitor assembly automatically detects the locked state through its sensor and provides confirmation through the audible alarm without requiring user intervention. The system serves itself by monitoring its own state and communicating this information to the user, simplifying the operation while maintaining security.

Inventive Principle:

Principle #25Self-service

AI summary

A monitor for a security container includes a first monitor portion for attachment to one of a closure or a housing of the security container. The first monitor portion includes a sensor, an audible alarm, and a “spin-confirm” push-button for a user to confirm that a lock dial of the security container was spun to lock the security container closure shut. The audible alarm activates when the sensor indicates that the security container closure is open after a defined period of time. The audible alarm deactivates only when the sensor indicates that the security container closure is closed, and the “spin-confirm” push-button is activated. A “snooze” push-button can be provided for the user to temporarily pause or alter the audible alarm to work with the security container unsecured.
