Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In image forming devices, the overlap of code patterns and electronic documents during printing leads to mismatched coordinate origins, causing issues with margin setup, N-up printing, and image magnification/reduction, resulting in discrepancies between the position identified by the code pattern and the application processing the handwritten image.

Innovation Solution

An electronic document management system that includes a unit to manage the correlation between address information on the medium and the electronic document, generating correction information to align the position of the electronic document with the medium's coordinate system, ensuring accurate positioning and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a code pattern is overlapped with an electronic document during printing, then position information can be specified on the paper, but the coordinate origin specified by the code pattern and the coordinate origin identified by the application do not match

Engineering Contradiction:

Improveposition specification accuracyVSAvoidcoordinate system consistency

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent introduces a coordinate conversion table as an intermediary data structure that maps between the code pattern's coordinate system and the application's coordinate system. This table stores correspondence relationships between coordinates in both systems, enabling accurate translation and resolution of the coordinate mismatch problem while maintaining both coordinate systems independently.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms position information by changing coordinate parameters through the conversion table. When position data is read from the code pattern, the coordinates are transformed from the code pattern's coordinate system to the application's coordinate system using stored correspondence relationships, ensuring consistent parameter interpretation across different systems.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If an electronic document is magnified or reduced during printing, then the document can be scaled to fit, but the position of the image on the electronic document and the position of the actual printed image are different

Engineering Contradiction:

Improvedocument scaling capabilityVSAvoidimage position accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent stores scaling parameters (magnification/reduction ratios) in the coordinate conversion table along with coordinate correspondence data. When position information is translated, the system applies the appropriate scaling factor to adjust coordinates, maintaining position accuracy despite document magnification or reduction during printing.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If margin setup or N-up print is applied to an electronic document, then the document format can be adjusted, but the coordinate origin mismatch between the code pattern and the application becomes more significant

Engineering Contradiction:

Improvedocument formatting flexibilityVSAvoidcoordinate information accuracy

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The coordinate conversion table serves as a comprehensive intermediary that accounts for margin setup and N-up print configurations. It stores the relationship between code pattern coordinates and application coordinates under various formatting conditions, enabling accurate position translation even when margins or multi-page layouts are applied.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary coordinate conversion by pre-storing correspondence relationships in the conversion table before actual position reading occurs. This preliminary establishment of coordinate mappings ensures that when margin setup or N-up print is applied, the coordinate translation is already prepared and accurate, preventing coordinate information loss.

Inventive Principle:

AI summary

An electronic document management system includes an electronic document management unit that manages a correlation between address information that is printed on a surface of a medium to specify a position of the surface of the medium and an electronic document printed on the medium, and an accumulating unit that accumulates correction information describing a difference between a position of the electronic document on a document image and a position on the medium by a code image describing the address information printed on the surface of the medium together with the electronic document, in connection with the medium. The electronic document management unit inputs reading information of the code image, and corrects position information obtained from the reading information based on the accumulated correction information so that a position of the electronic document on the document image matches with a position on the medium by the code image.
