Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the Type-F unique command is used for IC card application selection in NFC communication, then the selection and application processing is achieved, but the command cannot be used in other communication schemes like UWB or BLE

Engineering Contradiction:

Improvecommunication scheme compatibilityVSAvoidapplication selection reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a communication scheme-specific command translation mechanism that acts as an intermediary. The translation unit converts Type-F unique commands into UWB or BLE compatible commands, enabling the NFC-based application selection mechanism to work across different communication schemes. This mediator resolves the incompatibility between NFC commands and non-NFC communication protocols.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a universal command translation framework that can handle multiple communication schemes (NFC, UWB, BLE) through a single translation unit. This universal mechanism allows the same application selection functionality to operate across different communication protocols by automatically translating commands into the appropriate protocol-specific format.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Length of stationary object

If UWB or BLE communication is used for touchless payment, then the communicable range is extended, but the Type-F unique command cannot be used for application selection

Engineering Contradiction:

Improvecommunicable rangeVSAvoidapplication selection operation

Core Design Contradiction:

Length of stationary objectVSEase of operation

Solution Approach 1:

The translation unit serves as an intermediary that bridges the gap between the extended-range UWB/BLE communication and the application selection mechanism. It receives Type-F unique commands and translates them into UWB or BLE compatible commands, maintaining ease of operation while enabling longer communication range.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the command format parameter to match the requirements of different communication schemes. The translation unit modifies the command structure from NFC-specific Type-F commands to UWB/BLE-compatible command formats, allowing the same operational flow to function across different communication ranges and protocols.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If multiple IC card applications are installed in the user terminal, then the payment flexibility is improved, but the correct application cannot be selected in non-NFC communication

Engineering Contradiction:

Improvepayment flexibilityVSAvoidcorrect application detection

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The translation unit acts as an intermediary that maintains the application selection capability across multiple installed applications. By translating the Type-F unique command into UWB/BLE compatible commands, it preserves the mechanism that detects and selects the correct application from multiple installed applications, even in non-NFC communication schemes.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements a feedback mechanism where the translation unit receives the communication scheme type as input and returns the appropriately translated command. This feedback loop ensures that the correct application is detected and selected by providing accurate command translation based on the detected communication scheme, maintaining payment flexibility across multiple applications.

Inventive Principle:

Principle #23Feedback

AI summary

A user terminal having a plurality of IC card applications performs payment processing using communication data of UWB communication with a payment device, and the user terminal selects an IC card application corresponding to the payment device used for the payment processing. The user terminal receives data from the payment device, performs search processing as to whether or not the user terminal has a specific communication scheme-compatible IC card application capable of processing communication data according to a specific communication scheme such as UWB communication on the basis of the received data, acquires an identifier (AID) of the detected application, and transmits the acquired identifier to the payment device. The payment device transmits a select command storing the AID received from the user terminal to the user terminal, and the user terminal starts the IC card application according to the select command.
