Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for analyzing receipt print data using multiple scripts are inadequate, as they do not allow for the effective addition or modification of analysis scripts, making it difficult to ensure intended results are achieved.

Innovation Solution

An information processing method that generates a new extraction condition based on the position and attribute of text data in receipt print information, allowing for the creation of a second extraction script group, which is tested using similar real-world print information to verify the intended results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a new extraction script is added to the existing extraction script group, then the extraction capability is enhanced, but it becomes difficult to verify whether the intended analysis results are achieved

Engineering Contradiction:

Improveextraction capabilityVSAvoidverification of analysis results

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by performing extraction tests using test print information before the new extraction script is fully deployed. The system automatically executes test extractions with the updated script group and compares results against expected outcomes, verifying correctness in advance before production use.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by automatically comparing the extraction results from test print information against expected results. The system provides feedback on whether the new extraction scripts are producing intended outcomes, allowing for verification and adjustment before full deployment.

Inventive Principle:

Principle #23Feedback

2Quantity of substance

If multiple extraction scripts are applied to print data, then comprehensive text extraction is achieved, but manual verification of each script's effectiveness becomes time-consuming

Engineering Contradiction:

Improveextracted text dataVSAvoidverification time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The patent applies self-service by enabling the system to automatically verify extraction script effectiveness without manual intervention. The system autonomously executes test extractions, compares results against expected outcomes, and determines whether scripts are functioning correctly, eliminating the need for manual verification of each script.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical verification process with an automated computational system. Instead of manually checking each extraction script's output, the system automatically performs extractions on test data and compares results programmatically, substituting human effort with automated processing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If extraction scripts are modified to improve text extraction accuracy, then extraction precision is enhanced, but the risk of introducing errors increases

Engineering Contradiction:

Improveextraction accuracyVSAvoiderror introduction risk

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies beforehand cushioning by creating a protective verification layer between script modification and production deployment. Test print information serves as a cushioning buffer, allowing errors to be detected in the test environment before modified scripts affect production operations, preventing error propagation.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

An information processing method includes: a generation step of generating, based on at least one of a position and an attribute of the text data that is an extraction target and is included in print information that can be printed by a receipt printer, a new extraction condition under which text data is extracted; and a test step of extracting text data by applying, to test print information, an extraction condition group including one or two or more preset extraction conditions set in advance as a condition under which the text data is extracted, and the new extraction condition.
