Solution Overview

Problem

Current building access control systems require manual management by security personnel and inviters, leading to inefficiencies in controlling visitor and vehicle access, particularly with increased parking demands and illegal parking issues.

Innovation Solution

A system that generates temporary passwords based on visiting place information, allowing secure and convenient access control without a security manager, using an inviter's device, visitor's device, and a local access system to manage entrance gates and parking lots, with sequential password availability and vehicle plate number recognition for secure entry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual management by security personnel and inviters is used, then access control can be performed, but efficiency is reduced and operational complexity increases

Engineering Contradiction:
Improveaccess control efficiencyVSAvoidsystem operational complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables automatic access control where the inviter's device automatically generates and transmits temporary passwords to the visitor's device without requiring security personnel intervention. The system self-manages the entire access control process including password generation, transmission, and validation at entrance gates and parking lots.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical management processes with an automated electronic system. Instead of security personnel physically managing access, the system uses electronic communication between devices to generate, transmit, and validate digital passwords, substituting human operation with automated technological processes.

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

2Ease of operation

If free parking is provided for visitors, then visitor convenience is improved, but illegal parking by outsiders increases

Engineering Contradiction:
Improvevisitor parking convenienceVSAvoidillegal parking
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system introduces a digital password intermediary between the visitor and the parking access. Instead of direct free access, visitors must obtain a temporary password through the inviter's device, which acts as a mediator to authorize legitimate visitors while blocking outsiders from accessing the parking facility.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary authorization by requiring the inviter to generate and transmit a temporary password before the visitor can access the parking lot. This advance authorization step ensures that only pre-approved visitors gain access, preventing illegal parking by outsiders while maintaining convenience for legitimate visitors.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If temporary passwords are generated for each entrance gate and parking lot, then security is enhanced, but system complexity increases

Engineering Contradiction:
Improveaccess securityVSAvoidpassword management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The inviter's device serves multiple functions: it generates temporary passwords, transmits them to the visitor's device, and manages authorization for multiple locations (entrance gates and parking lots). This universal device consolidates what would otherwise require multiple separate systems, managing complexity centrally while maintaining high security through location-specific passwords.

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

AI summary

The present disclosure relates to an operating method of a building access control system that is performed by a server to make a visit reservation. The operating method of a building access control system includes: receiving, from an inviter's device, a visitor registration request comprising visitor information and visiting place information; generating at least one temporary password based on the visiting place information; transmitting, to a visitor's device, an invitation message indicating the at least one temporary password; and transmitting the visiting place information and the temporary password to a local access system identified based on the visiting place information, and the at least one temporary password is generated corresponding to each of at least one of one or more entrance gates and parking lots included in the local access system. Other various embodiments are also possible.
