Solution Overview

Problem

In a printing service environment, there is a need for automatic document output functionality that allows image forming apparatuses and user terminals to communicate and output documents without manual intervention, especially in scenarios where devices are connected through various communication methods and networks, ensuring seamless operation across different locations and connections.

Innovation Solution

The implementation of an automatic document output function in image forming apparatuses and user terminals, which detects access via communication connection states, retrieves documents based on setting information, and outputs them using print engines, leveraging communication interfaces for wireless and wired connections, including methods like Wi-Fi Direct, Bluetooth, and NFC, to facilitate automatic printing or transmission without user input.

1Ease of operation

If automatic document output function is implemented across multiple devices and networks, then user convenience and productivity are improved, but device complexity and communication protocol requirements increase

Engineering Contradiction:
Improveautomatic document outputVSAvoidcommunication interface
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The image forming apparatus is designed with multi-functional communication capabilities that can operate across different network types (Wi-Fi, Bluetooth, NFC, wired connections) and detect various access methods (direct device access, network access, router access). This universal design allows the same device to handle diverse communication scenarios without requiring separate systems for each communication method, thereby improving ease of operation while managing device complexity through integrated multi-functionality.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If document output is automated based on device access detection, then manual intervention is reduced, but reliability of automatic detection and retrieval processes becomes critical

Engineering Contradiction:
Improvedocument output speedVSAvoidautomatic detection accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements feedback mechanisms where the image forming apparatus continuously monitors communication connection states and device access patterns. When a user terminal or device accesses the apparatus through various methods (direct connection, network, or router), the system detects these access events and provides feedback by automatically retrieving and outputting the corresponding document. This feedback loop ensures that automatic detection is reliable and triggers appropriate document output actions without manual intervention.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by pre-configuring document retrieval rules and communication detection parameters before actual document output is needed. The image forming apparatus is set up to automatically detect specific device access patterns and retrieve corresponding documents from predetermined locations, so when access occurs, the document retrieval and output process can proceed immediately without delay or manual intervention, ensuring both productivity and reliability.

Inventive Principle:
Principle #10Preliminary action

AI summary

An example image forming apparatus includes a communication interface device, a print engine, a processor, and a memory that stores instructions executable by the processor. The processor may execute the instructions, as an automatic document output function is performed, to detect access of a user terminal through the communication interface device, based on detecting the access of the user terminal, obtain a document to be automatically output using setting information of the automatic document output function, and output the obtained document by using the print engine.
