Solution Overview

Problem

Existing NFC systems require users to manually activate an access control card for access control release operations, leading to a cumbersome process.

Innovation Solution

The method allows data interaction with an access-control-type NFC card reader using a non-access-control-type NFC emulation card by carrying a target identification code, enabling automatic access control release without manual activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a non-access-control-type NFC emulation card is used for data interaction, then the operation process is simplified, but the ability to perform access control release operations is lost

Engineering Contradiction:
Improveoperation processVSAvoidaccess control release capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The NFC emulation card is designed to perform multiple functions: it can operate as a non-access-control-type card for general data interaction and as an access-control-type card for access control release operations. The card includes both non-access-control contactless information and access-control contactless information, allowing it to adapt to different card reader types without requiring separate cards or manual activation.

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

Solution Approach 2:

The NFC emulation card pre-stores both non-access-control contactless information and access-control contactless information before use. When the card is activated, the access-control contactless information is prepared in advance, allowing the card to automatically perform access control release operations when interacting with an access-control-type card reader, eliminating the need for manual activation.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If an access-control-type NFC emulation card is activated manually before use, then access control release operations can be performed, but the operation process becomes cumbersome

Engineering Contradiction:
Improveaccess control release capabilityVSAvoidoperation process
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The NFC emulation card automatically determines whether to perform access control release operations based on the type of card reader detected. When interacting with an access-control-type card reader, the card automatically uses its access-control contactless information to release access control, without requiring the user to manually activate the card. This self-service mechanism eliminates the cumbersome manual activation process.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The NFC emulation card dynamically switches between different operational modes based on the card reader type. It can transition from a non-access-control state to an access-control state automatically when needed, making the card flexible and adaptive to different usage scenarios without requiring manual intervention.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If only one emulation card is kept active by default, then the NFC system is simple to manage, but the user cannot perform access control release operations without manual activation

Engineering Contradiction:
ImproveNFC system managementVSAvoidaccess control operation
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The NFC emulation card integrates both non-access-control and access-control functionalities into a single card. It stores both non-access-control contactless information and access-control contactless information, allowing one card to replace what would traditionally require multiple separate cards or manual switching, simplifying system management while maintaining full functionality.

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

Solution Approach 2:

The NFC emulation card pre-configures both types of contactless information before deployment. When the card is activated, the access-control information is already prepared and ready to use, eliminating the need for users to manually activate or switch between different card modes, thus maintaining simplicity while enabling access control operations.

Inventive Principle:
Principle #10Preliminary action
