Smart Communicator for Remote Access Authentication and Lock Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home automation systems lack the ability for residents to remotely communicate with visitors and control door locks bidirectionally, limiting their functionality to visitor identification, video, and voice functions, and do not support real-time communication or monitoring of visitors when the resident is not home.
Innovation Solution
An intelligent access authentication system utilizing a smart communicator that configures access approval levels, communicates with visitors, and remotely controls door locks through a home network server, enabling bidirectional communication and monitoring of visitor movements, even when the resident is not present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional home automation systems use basic video door phone functionality, then visitor identification is achieved, but real-time remote communication and bidirectional control capabilities are lost
Solution Approach 1:
The smart communicator serves multiple functions: it acts as a remote control for the door lock, a communication device for real-time video/audio interaction with visitors, and a monitoring terminal for receiving access information. This multi-functionality resolves the contradiction by enabling remote communication without requiring separate dedicated devices for each function.
Solution Approach 2:
The home server acts as an intermediary between the door lock, door phone, and smart communicator. It receives access requests from the door lock, captures video/audio from the door phone, and relays this information to the smart communicator. This intermediary architecture enables complex bidirectional communication and control while maintaining relatively simple individual device structures.
2Reliability
If the system provides comprehensive visitor monitoring and authentication, then access security is improved, but system complexity increases
Solution Approach 1:
The system pre-configures access approval levels and registered visitor information in advance. When a visitor attempts to access the home, the door lock automatically checks the visitor's ID against the pre-registered information and determines the appropriate access level before granting or denying access. This preliminary configuration approach improves authentication reliability while reducing the complexity of real-time decision-making.
Solution Approach 2:
The system implements a feedback mechanism where the door lock sends access request information to the home server, which then provides authentication decisions back to the door lock. The smart communicator also receives real-time feedback about visitor status and access outcomes. This feedback loop ensures reliable authentication while distributing system complexity across multiple components rather than concentrating it in one device.
3Ease of operation
If bidirectional remote control is implemented, then user convenience is enhanced, but communication protocol complexity increases
Solution Approach 1:
The home server serves as a communication intermediary that handles the complexity of bidirectional control protocols. It receives simple control commands from the smart communicator (such as 'unlock door' or 'deny access'), translates these into appropriate signals for the door lock, and manages the communication with the door phone. This intermediary approach enhances user convenience by providing intuitive remote control while isolating the communication protocol complexity within the home server.

AI summary
Disclosed is an intelligent access authentication system and method. The intelligent access authentication system includes a door lock that can be locked and released in a predetermined manner, a door phone for communicating with the visitor; a smart communicator which configures access approval levels of expected visitors and access authentication information for each access approval level, communicates with the visitor, and controls the door lock, and a home network server which stores the access approval levels of expected visitors and access authentication information for each access approval level received from the smart communicator, checks the access approval level of the visitor attempting to release the door lock by referring to previously stored information, and transmits a door lock operating command to the door lock according to the access approval level of the visitor. In the present invention, the resident can check the visitor and control the door lock to be released according to the access approval level of the visitor, even at a remote location.
