NFC Connection Information Segmentation for Storage Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face storage limitations for connection information, leading to potential deletion of important access point details when storing temporary connection information for handover processes, which affects user convenience.
Innovation Solution
Implement a system where connection information acquired through proximity wireless communication, such as NFC, is managed to differentiate between temporary and permanent connections, allowing only temporary information to be deleted after use, while preserving user-inputted and important connection details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection information is stored each time handover is performed, then automatic reconnection convenience is improved, but storage capacity is exceeded and important information is deleted
Solution Approach 1:
The patent segments connection information into two distinct categories: temporary connection information (from handover) and important connection information (user-inputted). By creating separate storage areas for each type, the system can manage storage capacity effectively while preserving important information and automatically managing temporary information.
Solution Approach 2:
The patent applies different storage policies to different types of connection information. Temporary connection information is stored in a first storage area with automatic deletion after use, while important connection information is stored in a second storage area with preservation. This localized quality approach resolves the contradiction by treating different data differently.
2Adaptability or versatility
If temporary connection information is stored, then handover functionality is enabled, but storage is cluttered and important information may be deleted
Solution Approach 1:
The patent divides the storage system into separate areas: a first storage area for temporary connection information and a second storage area for important connection information. This segmentation ensures that handover functionality is enabled through temporary storage while protecting important information from being overwritten or deleted.
Solution Approach 2:
The patent implements automatic deletion of temporary connection information from the first storage area after it has been used for handover. This discarding mechanism prevents storage clutter and protects important information while maintaining the necessary handover functionality.
3Ease of operation
If all connection information is preserved, then user convenience is improved, but storage efficiency deteriorates
Solution Approach 1:
The patent applies different retention policies to different types of connection information based on their importance. Important connection information is preserved indefinitely in the second storage area, while temporary connection information is automatically deleted after use from the first storage area. This local quality approach maintains user convenience for important connections while optimizing storage efficiency.
Solution Approach 2:
By segmenting storage into two distinct areas with different management policies, the system achieves both user convenience (through preservation of important information) and storage efficiency (through automatic cleanup of temporary information).

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach optimizes storage by ensuring temporary connection information is deleted after use, preventing clutter on history screens and protecting important access point information, thus enhancing user convenience and maintaining efficient wireless communication.

AI summary
A portable terminal transmits a print job to a print apparatus, by connecting to an access point based on connection information acquired from an NFC tag. On completion of the transmission of the print job, the portable terminal deletes the connection information acquired from the NFC tag, from a memory, so that the connection information acquired from the NFC tag is not displayed in a connection history.
