Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when switching wireless communication methods between an information processing device and an image forming device, requiring them to physically move to the device's location for NFC-based communication before switching to a longer-range method like Wi-Fi Direct for data transfer.
Innovation Solution
Implementing a system where the image forming device can automatically detect and connect to a Wi-Fi Direct network after an initial NFC-based handover request, allowing seamless communication method switching without user intervention, enabling data transmission over a longer-range Wi-Fi Direct connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC system is used for initial connection, then connection establishment is reliable, but user convenience deteriorates due to requiring physical proximity
Solution Approach 1:
The system performs preliminary actions by establishing NFC connection first to exchange connection information, then proactively switches to Wi-Fi Direct for data transmission. This preliminary NFC interaction enables subsequent long-range communication without requiring user presence at the image forming device location.
Solution Approach 2:
NFC acts as an intermediary for initial connection establishment and information exchange, then the system transitions to Wi-Fi Direct as the primary communication channel. The NFC intermediary enables seamless handover to long-range communication, improving user convenience while maintaining connection reliability.
2Length of stationary object
If Wi-Fi Direct is used for data transmission, then communication range is extended, but handover complexity increases
Solution Approach 1:
The system merges NFC and Wi-Fi Direct communication methods into a unified handover process. NFC is used for initial connection and information exchange, while Wi-Fi Direct takes over for data transmission. This merging eliminates the need for manual intervention and simplifies the overall handover complexity.
Solution Approach 2:
The image forming device automatically performs the handover from NFC to Wi-Fi Direct without requiring user intervention. The system self-manages the communication method switching by using NFC-exchanged information to establish Wi-Fi Direct connection, thereby reducing handover complexity despite extended communication range.
3Adaptability or versatility
If manual handover is required, then communication method switching is controllable, but user time consumption increases
Solution Approach 1:
The system implements automatic handover where the image forming device autonomously switches from NFC to Wi-Fi Direct communication without requiring user control actions. This self-service approach maintains adaptability in communication method switching while eliminating user time consumption during the handover process.
Solution Approach 2:
The handover process maintains continuity of useful action by seamlessly transitioning from NFC connection establishment to Wi-Fi Direct data transmission. The automatic switching ensures uninterrupted communication flow, preserving adaptability while minimizing user time consumption through elimination of manual intervention steps.

AI summary
An image processing system may be configured to perform communications using multiple communication protocols. The system may further obtain and transmit, to an information processing apparatus, connection information for one or more other image processing apparatuses or devices. In one example, communication between the information processing apparatus and a first image processing apparatus may be performed according to a first communication protocol while the connection information for the one or more other image processing apparatus may correspond to communications using a second communication protocol.
