Solution Overview

Problem

Conventional paper sheet processing machines do not allow for setting the upper limit number of sheets to be stacked based on the details of the sort type, such as currency type, denomination, fitness, and orientation of banknotes.

Innovation Solution

A paper sheet processing machine with an identification unit to identify banknotes and a control unit that reads and sets the upper limit number of banknotes to be stacked in stacking units based on the details of the sort type from a storage unit, allowing for different upper limits for various types of banknotes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single upper limit number of sheets is set for the stacking unit, then the device complexity is reduced and operation is simplified, but the adaptability to different sort types (currency type, denomination, fitness, orientation) is insufficient

Engineering Contradiction:
Improveadaptability to different sort typesVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the upper limit setting by creating multiple stacking units (first stacking unit, second stacking unit, etc.) that can be assigned to different sort types. Each stacking unit can have its own upper limit number stored in the storage unit, allowing differentiated control for different currency types, denominations, fitness levels, or orientations without requiring a single complex configuration system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by pre-storing multiple upper limit numbers in the storage unit, each corresponding to different sort type conditions. When a banknote is identified and sorted, the control unit automatically retrieves the appropriate pre-stored upper limit from the storage unit based on the identified sort type, eliminating the need for real-time calculation or complex decision-making during operation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the upper limit number is set uniformly for all stacking units, then the ease of operation is improved, but the productivity is reduced due to inability to optimize stacking for different sort types

Engineering Contradiction:
Improvestacking efficiencyVSAvoidease of operation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the upper limit number configurable and changeable based on operational requirements. The control unit can set different upper limit numbers for different stacking units dynamically, allowing the system to adapt to varying productivity needs for different sort types while maintaining ease of operation through automated control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements self-service by automatically selecting and applying the appropriate upper limit number from the storage unit based on the identified sort type of the banknote. The control unit autonomously configures the stacking parameters without requiring manual intervention for each sort type, thereby improving productivity while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If detailed sort type information is stored and processed, then the measurement precision of banknote identification is improved, but the loss of information increases due to the large amount of data to be managed

Engineering Contradiction:
Improveidentification precisionVSAvoidinformation management burden
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent extracts only the essential sort type information (currency type, denomination, fitness, orientation) that is necessary for determining the appropriate upper limit number. The control unit processes and stores only these key identification results in the storage unit, rather than managing all possible banknote attributes, thereby maintaining high identification precision while reducing the information management burden.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary action by pre-categorizing and storing upper limit numbers in the storage unit according to different sort type combinations. This pre-organization of data allows the control unit to quickly retrieve the appropriate upper limit based on identified banknote characteristics without needing to process or manage excessive detailed information during operation.

Inventive Principle:
Principle #10Preliminary action
