Solution Overview

Problem

Existing NFC devices face challenges in conserving memory and computing resources when accessing partial applications over a network without having the full application installed, which can lead to incompatibility with devices requiring NFC functionality.

Innovation Solution

A user device executes a web-browsing application to scan an NFC tag, receives data, stores it, and generates a URL with parameters to launch a partial application, enabling indirect NFC functionality without installing the full application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the full application is installed on the NFC device, then NFC functionality is available, but memory and computing resources are consumed

Engineering Contradiction:

ImproveNFC functionality availabilityVSAvoidmemory and computing resources

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary NFC functionality from the full application and makes it available through a partial application accessed via URL parameters. This allows the NFC device to provide NFC capabilities without installing the complete application, thereby conserving memory and computing resources while maintaining the required functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary mechanism where URL parameters serve as a mediator to pass NFC-related data between the web-browsing application and the partial application. This intermediary approach enables the partial application to access NFC functionality indirectly through the URL parameters without requiring full application installation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the full application is installed on the NFC device, then NFC functionality is available, but device complexity increases

Engineering Contradiction:

ImproveNFC functionality availabilityVSAvoidapplication installation requirements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts NFC functionality from the full application and makes it accessible through a partial application launched via URL parameters. This extraction eliminates the need to install the complete application while maintaining NFC capabilities, thereby reducing device complexity and installation requirements.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements partial action by providing only the necessary NFC functionality through the partial application rather than the full application. This partial approach reduces the complexity of application installation and device configuration while maintaining the essential NFC functionality required for the use case.

Inventive Principle:

Principle #16Partial or excessive action

3Quantity of substance

If a partial application is accessed over the network, then memory and computing resources are conserved, but NFC functionality may be incompatible with devices requiring it

Engineering Contradiction:

Improvememory and computing resourcesVSAvoidNFC functionality compatibility

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent introduces URL parameters as an intermediary mechanism to bridge the partial application with NFC functionality. The URL parameters carry necessary data that enables the partial application to interact with NFC-enabled devices, ensuring compatibility while maintaining resource conservation benefits of the partial application approach.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent performs preliminary action by pre-configuring the URL parameters with necessary NFC-related data before launching the partial application. This preliminary preparation ensures that when the partial application accesses NFC functionality, the required data is already in place, guaranteeing compatibility with NFC-enabled devices.

Inventive Principle:

Principle #10Preliminary action

AI summary

In some implementation, a device may execute a web-browsing application installed on the device. The device may scan, by a near-field communication (NFC) reader of the device and in connection with the web-browsing application, an NFC tag of an interaction card associated with an account of a user. The device may receive, from the interaction card, data associated with the account of the user. The device may store the data as coded data in the web-browsing application. The device may generate a uniform resource locator (URL) associated with a partial application having reduced functionality. The URL may include one or more URL parameters containing the coded data. The device may launch the partial application based on a user interaction with a hyperlink associated with the URL. The partial application may parse the URL parameter(s) and may decode the coded data to be used by the partial application.
