Solution Overview

Problem

Conventional banknote handling systems face challenges in accurately reading all characters of banknote serial numbers, leading to increased failure rates and reduced efficiency and accuracy in managing banknote inventory due to permitted partial recognition of serial numbers, resulting in erroneous matching and storage of similar serial numbers.

Innovation Solution

A banknote handling method that involves sequential recognition and transportation of banknotes based on comparisons between serial numbers, allowing for partial recognition of characters and separating banknotes with similar serial numbers into different storage units to maintain handling efficiency and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If strict full recognition of serial numbers is required, then measurement precision is improved, but productivity deteriorates due to increased failure rate

Engineering Contradiction:

Improveserial number recognition accuracyVSAvoidbanknote handling efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent applies partial recognition by allowing a predetermined number of unrecognized characters in serial numbers. Instead of requiring complete recognition of all characters, the system accepts banknotes with partially recognized serial numbers (up to a threshold of unrecognized characters), thereby maintaining productivity while achieving sufficient measurement precision for inventory management.

Inventive Principle:

Principle #16Partial or excessive action

2Productivity

If partial recognition of serial numbers is permitted, then productivity is improved, but measurement precision deteriorates leading to erroneous matching

Engineering Contradiction:

Improvebanknote handling efficiencyVSAvoidserial number recognition accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent implements feedback mechanisms where the system continuously monitors recognition results and adjusts its behavior. When a banknote with partially recognized serial number is processed, the system records the unrecognized characters and uses this information to improve future recognition attempts, while still maintaining the ability to handle banknotes efficiently with partial recognition.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent changes the parameter of recognition strictness by introducing a configurable threshold for the number of unrecognized characters. This parameter adjustment allows the system to flexibly balance between productivity (accepting more banknotes with partial recognition) and measurement precision (maintaining sufficient accuracy for inventory management).

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If banknotes with similar serial numbers are stored together, then device complexity is reduced, but reliability deteriorates due to erroneous matching

Engineering Contradiction:

Improvestorage management complexityVSAvoidinventory management accuracy

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent applies segmentation by dividing the storage system into multiple storage units based on serial number characteristics. Banknotes with similar serial numbers are routed to different storage units, creating segmented storage zones. This segmentation prevents erroneous matching while maintaining manageable device complexity through systematic organization.

Inventive Principle:

Principle #1Segmentation

4Ease of operation

If conventional inventory management is used with partial recognition, then ease of operation is maintained, but reliability deteriorates due to erroneous matching

Engineering Contradiction:

Improveoperation simplicityVSAvoidinventory management accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces an intermediary comparison step between serial numbers before final storage assignment. This intermediary process checks for similarity between serial numbers and prevents erroneous matching while maintaining ease of operation through automated comparison logic that operates transparently to the user.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A banknote handling method includes: sequentially feeding banknotes from an inlet to an inside of an apparatus; sequentially recognizing the banknotes fed to the inside of the apparatus using a recognition circuit; transporting a first banknote to a first storage for the first denomination by a conveyor and storing the first banknote in the first storage, wherein the recognition circuit recognizes that the first banknote is a banknote of the first denomination and has a first serial number; after recognizing the first banknote by the recognition circuit, transporting a second banknote to a second storage by the conveyor based on a comparison between the first serial number and the second serial number performed by a controller, wherein the recognition circuit recognizes that the second banknote is a banknote of the first denomination and has the second serial number.
