Solution Overview

Problem

Existing access control systems are complex and require multiple steps or components to manage access, especially when unauthorized access is detected, which can lead to user confusion and security vulnerabilities.

Innovation Solution

An integrated access control system with a door strip containing an electronic lock, badge reader, and intercom that automatically initiates video communication with a remote terminal if unauthorized access is attempted, allowing residents to verify and grant access remotely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the access control system automatically initiates video communication upon detecting unauthorized access attempts, then security is enhanced through visual verification, but the system complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the badge reader and video intercom into a single integrated access control system. The door strip includes both the access rights reader and outdoor intercom equipment, merging identification and communication functions into one unified device that automatically initiates video calls when unauthorized access is detected

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The outdoor intercom equipment serves multiple functions: it acts as both a communication device for authorized users and an automatic security response system. The same device that enables video calls for legitimate access requests also automatically initiates video communication when unauthorized access attempts are detected, eliminating the need for separate security monitoring equipment

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

2Ease of manufacture

If the access control system integrates multiple functions into a single door strip, then installation complexity is reduced, but the device complexity increases

Engineering Contradiction:
Improveinstallation complexityVSAvoiddevice complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent integrates the electronic lock, badge reader, and intercom equipment into a single door strip assembly. This consolidation reduces the number of separate components that need to be installed and wired, simplifying installation while the internal integration manages the complexity within the unified device

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the system requires manual initiation of intercom communication, then the system is simpler to operate, but security response time is delayed

Engineering Contradiction:
Improveoperation simplicityVSAvoidsecurity response time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs automatic detection and initiation of video communication without requiring manual user action. The access control device automatically detects unauthorized access attempts and initiates video calls with the remote terminal, enabling immediate security response while maintaining simple operation for authorized users who can still manually initiate intercom communication when needed

Inventive Principle:
Principle #25Self-service

AI summary

This access control system includes a control unit (110) configured to perform the following operations: - determine whether access rights acquired by a reader (40) satisfy pre-recorded access conditions, and - if these acquired access rights satisfy these pre-recorded access conditions, in response, automatically command the movement of an electronic lock from a locked state to an unlocked state without involving a remote terminal, and - if the access rights acquired by the reader do not satisfy the pre-recorded access conditions, in response, automatically trigger the establishment of communication with the remote terminal.
