Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional document distribution systems often experience layout changes and character corruption when displaying documents on browsing terminals and printing them, due to differences in application programs and image processing between these devices.

Innovation Solution

A document distribution server generates image data from received printing data using a raster image processor, distributing this image data to both browsing terminals and printers, ensuring consistent output across different devices and applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional document distribution systems use application programs and image processing on browsing terminals and printers, then devices can display and print documents, but layout changes and character corruption occur due to differences in applications and processing

Engineering Contradiction:

Improvedevice compatibilityVSAvoiddocument image consistency

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent introduces an image generation unit in the server that acts as an intermediary between the document data storage and the distribution to terminals. This unit generates standardized image data from the stored document data, ensuring that all browsing terminals and printers receive consistent image data regardless of their different applications and processing capabilities, thereby preventing layout changes and character corruption

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the data format parameter from variable application-specific formats to a standardized image data format. By converting document data into standardized images before distribution, the system ensures consistent display across different devices while maintaining adaptability to various terminal types

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If browsing terminals select application programs to open document data, then documents can be displayed using different applications, but layout changes and character corruption may occur

Engineering Contradiction:

Improvedocument display flexibilityVSAvoidimage integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The image generation unit serves as a mediator that converts document data into standardized images before distribution, eliminating the need for browsing terminals to use different application programs. This ensures reliable image integrity while maintaining ease of operation through standardized processing

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs image generation in advance at the server side before distribution to terminals. By pre-converting document data into standardized images, the system ensures image integrity is maintained throughout distribution, while terminals can simply display the pre-processed images without complex application selection

Inventive Principle:

Principle #10Preliminary action

AI summary

A document distribution server includes a first communication interface that receives printing data corresponding to a document, a processor that generates image data corresponding to the document, based on the received printing data, a memory that stores the received printing data and the generated image data, and a second communication interface that distributes the generated image data in response to a request for a document which corresponds to the generated image data stored in the memory.
