Solution Overview

Problem

Existing access control systems require substantial hardware, such as access card readers and video cameras, which can be costly and cumbersome.

Innovation Solution

A mobile device running an access control application communicates via multiple wireless protocols to control access to secure areas, utilizing a wireless gateway and door lock module, with access rights managed by a server and verified through the mobile device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional access control systems use access card readers and video cameras, then access control reliability is improved, but device complexity and cost increase

Engineering Contradiction:
Improveaccess control reliabilityVSAvoidhardware complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mobile device serves multiple functions: it acts as both the access credential (replacing access cards) and the access controller (replacing card readers and video cameras). The access control application on the mobile device performs identification, authentication, and control functions that traditionally required separate dedicated hardware systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent creates a virtual copy of the access control system functionality within the mobile device's software application. Instead of requiring physical access cards and dedicated readers, the system uses a software-based access control application that replicates the identification and control functions in a virtual environment, reducing hardware requirements.

Inventive Principle:
Principle #26Copying

2Reliability

If access control systems use dedicated hardware like access card readers, then access control functionality is reliable, but ease of operation deteriorates

Engineering Contradiction:
Improveaccess control functionalityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mobile device that users already carry and are familiar with is transformed into a multi-functional access control system. The same device used for communication and information access also serves as the access credential and controller, eliminating the need to carry separate access cards or remember multiple authentication methods.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables users to manage their own access rights and credentials through the access control application on their mobile device. Users can independently control access to their personal areas and manage their access permissions without requiring manual intervention or additional hardware interaction.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If access control systems use video cameras and video processing, then measurement precision of user identification is improved, but loss of time increases

Engineering Contradiction:
Improveuser identification accuracyVSAvoidaccess time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary authentication by verifying the mobile device's identity and access rights before the user physically approaches the door. The access control application pre-establishes the user's credentials and permissions, so that when the user arrives at the access point, the authentication process is already complete or can be executed instantly, eliminating the need for time-consuming video processing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical and optical systems (video cameras and video processing) with an electronic communication-based system using wireless protocols. The mobile device communicates access credentials electronically through wireless communication modules, providing instant verification without the need for visual capture and processing of video images.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A system includes a door lock module for locking and unlocking a door and a mobile device running an access control application that is configured to receive access rights from a server and store the access rights in the mobile device. The access control application identifies a door ID of the door to the secure area and determines whether the access rights stored in the mobile device grant the user assigned to the mobile device access to the secure area of the facility. If so, the access control application sends a door access request to the door lock module to unlock the door, and if not, no door access request is sent. The access control application is configured to send a log entry corresponding to each door access request initiated by the mobile device to the server.
