Solution Overview

Problem

Conventional access control systems face issues with user convenience, security, and reliability due to the need for separate authentication devices, potential loss of authentication means, and vulnerabilities in personal information storage, as well as communication disruptions affecting access.

Innovation Solution

An access control method and system that utilizes a user's terminal to perform authentication by detecting and communicating with an access control device, using identification and biometric information to determine access rights, and enabling door opening through a communication channel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If authentication is performed through a separate authentication device, then access control function is achieved, but user convenience deteriorates and authentication time increases

Engineering Contradiction:

Improveaccess control functionVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the authentication device functionality directly into the terminal device. The terminal device includes an authentication unit that can perform authentication operations locally without requiring a separate authentication device, thereby improving user convenience while maintaining access control reliability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The terminal device is designed to perform multiple functions including communication with the access control device, storing access right information, and performing authentication operations. This multi-functionality eliminates the need for separate authentication devices and improves ease of operation

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate authentication means are carried by users, then authentication capability is maintained, but loss risk increases and security deteriorates

Engineering Contradiction:

Improveauthentication capabilityVSAvoidloss risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Instead of using physical authentication cards that can be lost or stolen, the patent uses digital copies of authentication information stored in the terminal device. The access right information is stored as data that can be replicated and managed electronically, eliminating the physical loss risk while maintaining authentication capability

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The access control device acts as an intermediary that manages authentication information centrally. Rather than users carrying separate authentication means, the system uses the terminal device as an intermediary to store and manage access right information, reducing the risk of loss and unauthorized access

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If access control is managed by a control server, then centralized management is achieved, but system reliability deteriorates when communication is disconnected

Engineering Contradiction:

Improvecentralized managementVSAvoidaccess control reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The terminal device stores access right information locally in advance, so that when communication with the access control device is disconnected or the server is disabled, the terminal can still perform authentication operations using the pre-stored information. This preliminary action ensures continuous operation and maintains reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system prepares backup authentication capability by storing access right information in the terminal device before communication disruptions occur. This beforehand cushioning ensures that authentication can continue even when the centralized server is unavailable, maintaining system reliability

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Reliability

If access right information is stored in authentication device, then authentication function is maintained, but personal information security deteriorates

Engineering Contradiction:

Improveauthentication functionVSAvoidpersonal information security

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the authentication function from the traditional authentication device and integrates it into the terminal device. The access right information is stored in the terminal rather than in a separate authentication device, thereby maintaining authentication functionality while improving personal information security through better control over where sensitive data is stored

Inventive Principle:

Principle #2Taking out (Extraction)
