Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face difficulties in testing and troubleshooting NFC circuitry in their mobile devices, as they require physical presence at a POS terminal and lack of expertise in NFC issues, leading to logistical and cost challenges for both consumers and manufacturers.
Innovation Solution
A system and method allowing consumers to test NFC circuitry using an NFC test application, which requires a second NFC-enabled device and a central server for diagnostic testing, enabling remote troubleshooting and correction of issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If consumers physically transport mobile devices to test facilities for NFC troubleshooting, then diagnostic accuracy is improved, but logistical complexity and cost increase
Solution Approach 1:
A central server acts as an intermediary between the consumer's mobile device and the testing infrastructure. The server receives test data from the mobile device via NFC communication with a second device, performs centralized analysis, and provides diagnostic results, eliminating the need for physical transport to test facilities while maintaining diagnostic accuracy
Solution Approach 2:
The system creates a virtual copy of the test facility functionality within the consumer's mobile device through an NFC test application. The application enables the device to perform self-diagnosis and transmit test data remotely, replicating the diagnostic capabilities of physical test facilities without requiring physical presence at those facilities
2Measurement precision
If consumers physically transport mobile devices to test facilities for NFC troubleshooting, then diagnostic accuracy is improved, but time consumption increases
Solution Approach 1:
The NFC test application enables consumers to perform self-diagnosis of their mobile devices' NFC circuitry without external assistance. The application guides consumers through the testing process, automatically collects test data, and transmits results to a central server, allowing diagnostic services to be obtained at the consumer's convenience without scheduling appointments or traveling to facilities
3Ease of operation
If manufacturers provide replacement devices instead of remote troubleshooting, then customer satisfaction is improved, but cost increases
Solution Approach 1:
The system performs preliminary diagnostic assessment through the NFC test application before determining the appropriate course of action. By accurately identifying whether an issue exists and its nature beforehand, the system avoids unnecessary device replacements, directing consumers to remote troubleshooting only when needed and reducing wasteful manufacturing and distribution of replacement devices
4Ease of operation
If consumers lack expertise in NFC issues, then ease of use is improved, but diagnostic capability deteriorates
Solution Approach 1:
The central server acts as an expert intermediary that receives raw test data from the consumer's mobile device, performs sophisticated analysis using specialized algorithms and databases, and translates the results into consumer-friendly diagnostic conclusions. This separates the simple data collection performed by the consumer from the complex diagnostic analysis requiring expertise
Solution Approach 2:
The system replaces the need for human expert intervention with an automated electronic diagnostic system. The NFC test application and central server together form an automated testing and analysis system that performs diagnostic functions previously requiring trained technicians, making expert-level diagnostics accessible to all consumers

testing by a consumer of the near-field communications (NFC) circuitry of his or her mobile device
Data Source
AI summary
Near-Field Communication (NFC) test systems, apparatus and processes enable consumers to thoroughly and easily test the NFC circuitry and short range communications software of their mobile devices. In an embodiment, a processor of a consumer's mobile device receives input to initialize an NFC test application and displays a prompt on a display screen for the consumer to position his or her mobile device to communicate with an NFC-enabled device. When the processor receives input indicating a correct communication position, a shared identity is exchanged with the NFC-enabled device and transmitted to a central server computer. Next, the processor receives a plurality of NFC test instructions, communicates in a transaction mode of operation and then in a terminal mode of operation with the NFC-enabled device, and transmits NFC test data to the central server computer. In some embodiments, the processor receives NFC test results from the central server computer and displays an indication of the NFC test results on a display screen.
