Solution Overview

Problem

Existing NFC-enabled mobile devices face challenges in efficiently adapting existing applications to support Near Field Communication (NFC) functionality, requiring developers to learn and implement NFC-specific APIs and formats, which increases development time and costs.

Innovation Solution

The NFC Share Framework Adaptor automatically wraps payload data in NDEF messages, inferring proper message parameters and interacting with the NFC API on behalf of applications, allowing non-NFC applications to share information without requiring direct NFC API implementation, thus simplifying the integration of NFC capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If applications directly implement NFC API and use NFC-specific formats, then NFC communication functionality is achieved, but development time and cost increase

Engineering Contradiction:

ImproveNFC communication functionalityVSAvoiddevelopment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces an intermediary component that translates between generic application data formats and NFC-specific NDEF message formats. This mediator handles the format conversion automatically, allowing applications to communicate using simple generic formats while the intermediary ensures proper NFC protocol compliance, thereby reducing development complexity and time without sacrificing NFC functionality

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a simplified copy or abstraction layer of the NFC communication interface that applications can use instead of the full NFC API. This copy provides the essential functionality needed for NFC communication but with a simplified interface that doesn't require developers to learn complex NFC-specific protocols, thus reducing development time while maintaining communication reliability

Inventive Principle:

Principle #26Copying

2Reliability

If applications directly implement NFC API and use NFC-specific formats, then NFC communication functionality is achieved, but development cost increases

Engineering Contradiction:

ImproveNFC communication functionalityVSAvoiddevelopment cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent creates a universal translation layer that can handle multiple NFC formats and protocols through a single generic interface. This multi-functional component serves applications across different platforms and NFC implementations, reducing the need for separate development efforts for each NFC scenario and thereby lowering overall development costs while maintaining full NFC functionality

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the interface parameters from complex NFC-specific formats to simple generic formats that applications can easily handle. By transforming the data representation parameters at the interface level, the system maintains full NFC capability while making the development process more cost-effective through simplified data handling

Inventive Principle:

Principle #35Parameter changes

3Reliability

If NFC-specific APIs and formats are required, then proper NFC communication is achieved, but application complexity increases

Engineering Contradiction:

ImproveNFC communicationVSAvoidapplication complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the complex NFC protocol handling logic from the application layer and places it in a separate translation component. This extraction removes the complexity burden from applications, allowing them to focus on their core functionality while the extracted translation layer handles all NFC-specific format conversions

Inventive Principle:

Principle #2Taking out (Extraction)
