Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face difficulty in determining which image formation device is closest to their current location when multiple devices are available, making it challenging to locate a device capable of printing desired media.

Innovation Solution

An image formation device and system that includes a processor to transmit user and device identification information to a server, receive a list of valid media, inquire about nearby devices with valid media, and notify users of the closest device capable of printing, allowing seamless printing across multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple image formation devices are available in a network, then printing service coverage is improved, but user ability to locate the closest device deteriorates

Engineering Contradiction:

Improveprinting service coverageVSAvoiddevice location determination

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a server as an intermediary that receives position information from multiple image formation devices and user terminal devices. The server performs the complex task of calculating distances and determining the closest device, relieving users of this computational burden and enabling easy device location despite multiple devices being available in the network.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback by having the server send the determined closest device information back to the user terminal device. This feedback loop provides users with immediate, actionable information about which device to use, transforming the complex multi-device environment into a simple user experience where the system automatically identifies the optimal device.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If user searches for devices with specific media capability, then printing capability is improved, but time consumption deteriorates

Engineering Contradiction:

Improvemedia-specific printing capabilityVSAvoiddevice searching time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having image formation devices register their position information and supported media types with the server in advance. When a user needs printing services, the server can immediately query this pre-registered information and return results without requiring real-time searching, thus reducing user waiting time while maintaining media-specific capability matching.

Inventive Principle:

Principle #10Preliminary action

AI summary

Processing circuitry of an image formation device transmits user identification information and device identification information to a server, receives an indication of a valid medium associated with the user identification information from the server, and determines whether the valid medium is contained in a tray. In response to a determination that the valid medium is not contained in the tray, the processing circuitry transmits an inquiry related to the valid medium to the server, receives, from the server, printing support information about another image formation device that contains the valid medium and is closest to a position indicated by position information associated with the device identification information, and outputs the printing support information to a user interface. The processing circuitry instructs a printer to perform image formation on the valid medium in response to a determination that the valid medium is contained in the tray.
