Door Security Device with Remote Motorized Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door latching mechanisms are easily bypassed by unauthorized individuals, require physical presence and keys for operation, and risk key loss leading to unauthorized access.
Innovation Solution
A door security device with a vertical support member and movable floor pressure member, enabled by a locking system that converts between locked and unlocked configurations remotely through a network, using a motor and toggle switch, eliminating the need for physical keys and allowing secure access management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional locking door latching mechanism is used, then the door can be secured against unauthorized entry, but the locking functionality can be easily defeated by persons with picking tools and knowledge
Solution Approach 1:
The patent replaces the traditional mechanical locking mechanism with an electro-mechanical system. A motor-driven bolt engagement mechanism is controlled by an electronic control circuit that can be actuated remotely via wireless communication. This substitution eliminates the physical key and traditional lock cylinder that are vulnerable to picking, replacing them with an electronic control system that authenticates users through alternative means (such as biometric sensors or coded signals) and actuates the locking mechanism electronically.
2Reliability
If a physical key is required to unlock the door, then the door can be secured, but the key can be lost or stolen allowing unauthorized access
Solution Approach 1:
The patent replaces the physical key system with an electronic authentication and control system. The electronic control circuit receives authentication signals (such as biometric data from sensors or coded wireless signals) and automatically actuates the motor-driven locking mechanism. This eliminates the need for physical keys that can be lost or stolen, while maintaining secure access control through electronic verification of authorized users.
Solution Approach 2:
The patent introduces an electronic control circuit and motor-driven mechanism as intermediaries between the user and the locking mechanism. Instead of direct mechanical key insertion and turning, the system uses electronic signal processing, authentication verification, and motor actuation to engage or disengage the bolt. This intermediary system provides enhanced security through electronic authentication while improving convenience by eliminating the need for physical key handling.
3Reliability
If a traditional lock mechanism is used, then the door can be locked, but the locking mechanism adds complexity to the door system
Solution Approach 1:
The patent integrates multiple functions into a single unified system. The electronic control circuit serves as the central hub that handles authentication verification, motor control, status monitoring, and wireless communication. The motor-driven mechanism replaces both the traditional lock cylinder and key operation. This multi-functional integration reduces the number of separate components (key cylinder, separate actuation mechanisms, multiple switches) while maintaining or enhancing security capabilities.
