Image Forming Handover Control for NFC and WLAN Authorization Limits
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 setting of connection information based on user instructions or information, ensuring a suitable connection method is chosen for the circumstances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image forming apparatus uses wireless LAN as the connection method for handover, then communication can be established between the mobile communication terminal and the MFP, but communication fails when the mobile communication terminal does not have authorization to access the network
Solution Approach 1:
The patent changes the connection method parameter based on network authorization status. When the mobile communication terminal lacks network authorization, the system switches from wireless LAN mode to direct peer-to-peer communication mode, allowing communication to continue without failing due to authorization restrictions
Solution Approach 2:
The system dynamically selects the appropriate connection method based on real-time conditions. The control unit determines whether to use wireless LAN or direct communication by evaluating network authorization status, making the connection method adaptable to changing network conditions rather than fixed
2Adaptability or versatility
If the image forming apparatus supports multiple connection methods, then adaptability to different circumstances is improved, but the complexity of selecting and managing connection methods increases
Solution Approach 1:
The control unit automatically determines which connection method to use based on pre-stored conditions and current network status. The system self-evaluates whether wireless LAN or direct communication is appropriate without requiring manual user intervention, reducing the operational complexity despite supporting multiple connection methods
Solution Approach 2:
The patent manages connection method complexity by using clear parameter-based decision logic. The control unit checks specific parameters (network authorization status) and automatically selects the appropriate connection method, simplifying the management of multiple connection options through systematic parameter evaluation
