Image Forming Device Handover with Authorization-Aware Connection Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses using NFC for handover to wireless LAN face issues when the mobile communication terminal lacks authorization to access the network, limiting the available connection methods.
Innovation Solution
The image forming apparatus is equipped with a short-range wireless communication unit that can operate in two modes: connecting to an external access point or functioning as an access point, allowing selection and writing of connection information based on user instructions or user information to suit the circumstances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the MFP uses wireless LAN for handover from NFC, then communication convenience is improved, but communication reliability deteriorates when the mobile terminal lacks network authorization
Solution Approach 1:
The patent changes the connection method parameter based on authorization status. When the mobile terminal lacks network authorization, the system switches from wireless LAN mode to direct peer-to-peer communication mode, allowing communication to continue reliably without requiring network access rights.
Solution Approach 2:
The patent implements dynamic adaptation of connection methods. The MFP automatically detects whether the mobile terminal has network authorization and dynamically switches between different connection modes (wireless LAN when authorized, direct communication when not authorized), making the system flexible and adaptable to changing authorization conditions.
2Adaptability or versatility
If the MFP supports multiple connection methods, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service through automatic detection and selection. The MFP automatically detects the mobile terminal's authorization status and connection capabilities, then autonomously selects and switches between appropriate connection methods without requiring manual user intervention, thereby managing complexity internally while presenting simplicity to the user.
Solution Approach 2:
The patent uses feedback mechanisms where the MFP detects the mobile terminal's authorization status and connection state, then adjusts the connection method accordingly. This feedback loop allows the system to adapt to changing conditions automatically, managing complexity through intelligent control based on real-time status information.
