Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in relay communication using Near Field Communication (NFC) due to compatibility issues arising from differences in radio frequency (RF) parameters between devices performing NFC communication and those processing transaction data, limiting the ability to use NFC services effectively.
Innovation Solution
The method involves allowing relay communication for specific applications by updating the RF parameter of one electronic device using the RF parameter of another device that processes NFC transaction information, enabling compatibility and user-controlled NFC service access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If relay communication is enabled for all NFC applications, then NFC service accessibility is improved, but compatibility issues arise due to RF parameter differences between devices
Solution Approach 1:
The patent dynamically changes RF parameters (such as frequency, modulation type, and data rate) based on the specific application and external device characteristics. The system selects appropriate RF parameters from a set of predefined configurations to match the requirements of different NFC services and external devices, thereby resolving compatibility issues while maintaining broad service accessibility
Solution Approach 2:
The patent implements dynamic RF parameter adjustment during runtime based on detected external device properties and application requirements. The system continuously monitors communication conditions and adapts RF parameters in real-time to optimize both compatibility and service functionality, rather than using fixed parameters
2Reliability
If relay communication is limited to certain applications, then compatibility is improved, but NFC service accessibility deteriorates
Solution Approach 1:
The patent creates a universal relay communication framework that can handle multiple NFC applications through a single standardized interface. The system provides common RF parameter management and device detection capabilities that work across different NFC services (payment, transit, authentication), making the system universally applicable while maintaining application-specific functionality
Solution Approach 2:
The patent introduces an intermediary layer between the NFC communication hardware and various applications. This intermediary manages RF parameter selection and device compatibility matching, allowing multiple applications to access NFC services through a unified compatibility-managing interface without requiring each application to handle RF parameter conflicts independently
3Reliability
If RF parameters are updated dynamically, then compatibility is improved, but device complexity increases
Solution Approach 1:
The patent pre-configures multiple sets of RF parameters for different NFC service types and external device categories before runtime. During operation, the system only needs to select from these pre-prepared configurations based on simple device detection, avoiding the need for complex real-time parameter calculation and synthesis
Solution Approach 2:
The patent implements self-service mechanisms where the system automatically detects external device properties and selects appropriate RF parameters without user intervention. The system autonomously manages parameter conflicts, performs compatibility checks, and adjusts settings based on detected conditions, reducing the perceived complexity for users while maintaining sophisticated parameter management internally
