Solution Overview

Problem

Existing document processing devices for financial documents face inefficiencies in handling and verifying currency bills and checks, including the risk of accepting counterfeit currency and the need for improved processing efficiency.

Innovation Solution

A document processing device that images currency bills and checks serially at different speeds, extracts relevant information, and compares it with declared amounts to ensure transaction balance, while also featuring an authentication system to detect counterfeit documents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If currency bills are transported at high speed for efficient processing, then productivity increases, but image quality and authentication accuracy may deteriorate

Engineering Contradiction:

Improveprocessing speedVSAvoidimage quality

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system dynamically adjusts transportation speed based on document type. Currency bills are transported at a first speed optimized for authentication, while deposit slips are transported at a second speed optimized for data extraction. This dynamic speed adjustment allows the system to maintain high overall productivity while ensuring each document type receives appropriate processing conditions for accurate authentication and imaging.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If multiple document types are processed in the same receptacle, then device complexity is reduced, but reliability of authentication may worsen due to mixed handling requirements

Engineering Contradiction:

Improvesingle receptacle designVSAvoidauthentication accuracy

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system segments the processing workflow into distinct phases: currency bill authentication phase and deposit slip data extraction phase. Although both document types share the same physical receptacle, the controller separates their processing sequences, authenticating currency bills first at optimized speed, then extracting data from deposit slips. This segmentation maintains reliability by ensuring each document type undergoes its specific processing requirements in the correct sequence.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary authentication of currency bills before proceeding to data extraction from deposit slips. By authenticating currency documents first and verifying their legitimacy, the system ensures that subsequent processing of associated deposit slips occurs only for valid transactions. This preliminary action enhances reliability by preventing processing of fraudulent documents while maintaining the simplified single-receptacle design.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If detailed verification of declared amounts is performed, then reliability of transaction balance improves, but processing time increases

Engineering Contradiction:

Improvetransaction balance verificationVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system replaces manual verification processes with automated optical character recognition (OCR) and image processing technologies. The imaging system captures images of deposit slips, and software algorithms automatically extract and verify declared amounts, comparing them against actual document contents. This substitution of mechanical/manual verification with automated optical and computational systems maintains high reliability in transaction balance verification while significantly reducing processing time.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A first prompt is displayed to insert a deposit slip that includes declared information. The deposit slip is received, transported at a first speed, and imaged. A total declared cash-in amount and a total declared check amount are extracted from image data associated with the deposit slip. The total declared cash-in amount is determined to be a non-zero number. A second prompt is displayed to insert currency bills. The currency bills are received, transported at a second speed, and imaged. Deposit information is generated from image data associated with each of the currency bills. The deposit information at least includes a calculated total cash deposit amount. The deposit information is compared with the declared information to determine if the deposit transaction is balanced.
