Solution Overview

Problem

Document preparation in digital mailrooms is labor-intensive and costly due to the need for manual handling and separation of documents, which involves marking and inserting slip sheets for efficient scanning, but this process is time-consuming and prone to errors.

Innovation Solution

A method and apparatus that use a document stamp with machine-readable patterns to separate and categorize documents, allowing for automated identification and separation of documents during scanning, eliminating the need for slip sheets and reducing manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual marking and slip sheet insertion are used for document categorization and separation, then document processing can be performed, but labor intensity and processing time increase significantly

Engineering Contradiction:

Improvedocument categorization and separationVSAvoiddocument processing speed

Core Design Contradiction:

Extent of automationVSProductivity

Solution Approach 1:

The patent replaces manual mechanical operations (marking documents with categories, inserting slip sheets) with an automated stamping system that applies machine-readable patterns directly to documents. This substitution eliminates the need for manual labor in categorization and separation tasks while maintaining high processing speeds.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The stamping system performs categorization and separation marking in advance during the stamping operation itself, before documents enter the scanning and processing workflow. By pre-applying machine-readable patterns and category codes to documents, the system eliminates the need for subsequent manual intervention to identify and separate documents.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If slip sheets are inserted between documents for efficient scanning, then batch scanning can be performed, but material waste and processing complexity increase

Engineering Contradiction:

Improvebatch scanning efficiencyVSAvoidslip sheet material

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The patent extracts and eliminates the slip sheet component from the document processing system by directly stamping separation information onto the documents themselves. The machine-readable patterns and category codes are applied directly to document pages, removing the need for separate slip sheets to indicate document boundaries and categories.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The stamping system performs multiple functions simultaneously: it applies category codes for classification, creates machine-readable patterns for automated identification, and establishes document separation points all in a single operation. This multi-functionality replaces the need for separate slip sheets that would otherwise be required for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If manual document preparation is performed, then documents can be categorized and separated, but error rates increase and consistency decreases

Engineering Contradiction:

Improvecategorization accuracyVSAvoidmanual handling complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The stamping system is self-regulating and automatically applies consistent machine-readable patterns and category codes according to predefined parameters. The system eliminates human judgment and manual handling variations by using automated stamping operations that produce uniform, machine-readable output, thereby improving categorization accuracy and reducing errors.

Inventive Principle:

Principle #25Self-service

4Extent of automation

If machine-readable patterns are applied to documents, then automated identification is enabled, but device complexity increases

Engineering Contradiction:

Improvedocument identificationVSAvoidstamping system

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single stamping device: category code application, machine-readable pattern generation, and document separation marking are all performed by one integrated system. This merging reduces overall system complexity compared to using separate devices for each function while maintaining high automation capabilities.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method for separating and categorizing documents includes receiving a scanned batch of documents. The batch includes scanned documents to which document separator stamps have been applied before scanning. Each stamp includes machine recognizable patterns applied on a same page of a document, spaced by a designated field for receiving a user-applied category code. The scanned batch of documents is processed to identify pages that contain a document separator, including identifying at least one of two spaced patterns. For a document page for which a document separator is identified, the the corresponding designated field is located and the category code associated with the designated field identified. The document containing the is separated from other documents in the batch based the identified separator and a document category is assigned to the document, based on the identified category code.
