NFC Tag Writing for Printers via Automatic Data Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses using NFC tags face issues with input errors when manually entering connection information, leading to failed printing operations due to incorrect information being written into the tags.
Innovation Solution
An information processing apparatus and method that includes a search unit for finding devices, a display unit for showing search results, a generation unit for creating tag information based on user-selected device identification, and a writing unit for securely writing this information into an NFC tag using short-range wireless communication, preventing input errors by confirming device connections before writing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection information is manually entered into the NFC tag, then the NFC tag can be written with device information, but input errors occur leading to incorrect information being stored
Solution Approach 1:
The printing apparatus automatically retrieves and writes its own connection information (IP address, MAC address) into the NFC tag without requiring manual user input. The system serves itself by having the controller read the connection information from its own storage unit and write it to the NFC tag through the NFC communication unit, eliminating human error in the input process.
Solution Approach 2:
The manual mechanical input process (typing connection information into a text field) is replaced with an automated electronic system. The controller automatically reads connection information from storage and writes it to the NFC tag through electronic communication, substituting the manual mechanical action with an automated electronic process that ensures accuracy.
2Reliability
If connection information is pre-written into the NFC tag from outside, then the tag can store necessary data, but the process becomes complex requiring external writing applications
Solution Approach 1:
The printing apparatus performs the writing operation itself without requiring external writing applications or tools. The controller internally stores connection information and uses its own NFC communication unit to write this information directly into the NFC tag, making the system self-sufficient and eliminating the need for complex external processes.
Solution Approach 2:
The printing apparatus integrates multiple functions into a single device: it stores connection information, communicates via NFC, and writes to NFC tags. This multi-functionality eliminates the need for separate external writing applications, simplifying the overall process while maintaining reliable information storage.
3Adaptability or versatility
If manual input of connection information is required, then user flexibility is maintained, but time is lost due to potential errors and rework
Solution Approach 1:
The system automatically performs the information writing task without requiring user input or error correction. The controller retrieves connection information from its own storage and writes it to the NFC tag autonomously, eliminating the time users would spend manually entering and potentially correcting errors while maintaining the flexibility of the NFC tag writing process.

Data Source
AI summary
There is provided an information processing apparatus and a method of controlling the same. The information processing apparatus performs a device search, displays search results of the device search, and generates tag information to be written into a short range wireless communication tag, using identification information of a device selected by a user based on the displayed search results. Then, the information processing apparatus writes the generated tag information into the short range wireless communication tag with the short range wireless communication.
