Solution Overview

Problem

Existing data distribution methods are inconvenient as they often require users to choose between printing or electronic data distribution, with additional processing steps for image data transmission, which can be cumbersome and inefficient.

Innovation Solution

A terminal device and information sharing system utilizing a relay server and DLNA communication method to enable wireless network connectivity between terminal devices, allowing for the transmission of print data as image data across different network segments, with identification images used to facilitate device ID acquisition and content distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If print data is output as image data for distribution, then paper consumption is reduced and time/effort for printing is saved, but additional processing steps (compression, archiving, transmission) are added making the process more complex

Engineering Contradiction:
Improvepaper consumptionVSAvoidprocessing complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The printer device is enhanced to perform multiple functions: it can both print physical copies and transmit image data directly to terminal devices. This multi-functionality eliminates the need for separate electronic distribution processes, reducing overall system complexity while maintaining paperless operation.

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

Solution Approach 2:

The printer acts as an intermediary device between the information processing device and terminal devices. It converts print data to image data and facilitates direct transmission to terminals, simplifying the distribution chain by eliminating the need for manual compression, archiving, and email attachment processes.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of substance

If material is distributed as image data via email attachment, then paper resources are saved, but users must retrieve and open the data from storage location requiring additional operations

Engineering Contradiction:
Improvepaper resourcesVSAvoiduser operation convenience
Core Design Contradiction:
Loss of substanceVSEase of operation

Solution Approach 1:

The system enables automatic delivery of image data directly to terminal devices without requiring user intervention for retrieval. The printer automatically transmits the data to designated terminals, and users receive notifications with direct access links, eliminating manual storage location navigation and file opening operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The printer serves as a mediator that handles the entire distribution process automatically. It converts print data to image data, transmits it directly to terminal devices, and manages the delivery process, freeing users from manual retrieval and opening operations while maintaining paperless distribution.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If terminal devices are in different network segments, then network flexibility and adaptability are improved, but direct communication between devices becomes impossible

Engineering Contradiction:
Improvenetwork flexibilityVSAvoidcommunication reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The information processing device acts as a gateway or intermediary between different network segments. It receives image data from the printer and forwards it to terminal devices in other segments, enabling reliable cross-segment communication while maintaining network flexibility and segmentation benefits.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system architecture explicitly supports network segmentation by allowing the information processing device to bridge different segments. This enables terminal devices to remain in separate network segments for security and management purposes while still allowing controlled communication through the information processing device gateway.

Inventive Principle:
Principle #1Segmentation

4Device complexity

If users must choose between printing or electronic distribution, then resource allocation is simplified, but convenience and efficiency of data distribution are reduced

Engineering Contradiction:
Improvedecision process simplicityVSAvoiddistribution convenience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The printer device is enhanced to perform both traditional printing and electronic distribution functions. Users can select either option from a unified interface, and the printer handles both workflows natively. This eliminates the need to choose between separate systems and provides convenience of both methods through a single device.

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

Solution Approach 2:

The patent merges the printing function and electronic distribution function into a single printer device. This consolidation allows users to access both distribution methods through one interface and one device, improving convenience and efficiency while maintaining simple resource allocation decisions.

Inventive Principle:
Principle #5Merging (Combining)
