Solution Overview

Problem

Banknote processing apparatuses face damage issues when units are reinserted with leftover banknotes between transfer guides, causing pulling forces that can damage the guides and units.

Innovation Solution

The apparatus features transfer guides with inclined edges that converge towards the conveyance path, allowing for a nested configuration with the units, enabling safe reinsertion without damaging the guides or units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If transfer guides are provided between units to enable safe transfer of banknotes, then banknote transfer safety is improved, but the risk of part damage during unit reinsertion increases

Engineering Contradiction:
Improvebanknote transfer safetyVSAvoidtransfer guide durability
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The transfer guide edges are designed with inclined surfaces (curved geometry) instead of sharp perpendicular edges. The inclined surface has an angle of 60 degrees or more with respect to the conveyance path direction, creating a gradual transition zone that reduces impact forces during unit reinsertion while maintaining banknote transfer safety.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The inclined surfaces on the transfer guide edges act as pre-designed cushioning elements that absorb and distribute impact forces before they can damage the transfer guide or unit. This beforehand cushioning design prevents the harmful pulling forces that occur when units are reinserted with leftover banknotes present.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Ease of operation

If units are made separable for maintenance and operation, then ease of operation is improved, but the risk of damage during unit movement increases

Engineering Contradiction:
Improveunit accessibilityVSAvoiddamage risk during movement
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The inclined surfaces on the transfer guide edges provide a gradual guide for unit reinsertion, reducing impact forces and damage risk during unit movement. This curved geometry design allows units to be easily separated and reattached while protecting against damage from leftover banknotes.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The inclined surface design creates a preliminary anti-action against potential damage during unit reinsertion. By designing the edge geometry to naturally guide units into place with reduced impact, the system preemptively counteracts the harmful forces that would otherwise occur during unit movement operations.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

To provide a banknote processing apparatus for reducing occurrence of part damage involved by movement of a unit.Provided is a banknote processing apparatus including: a first unit (10); a second unit (30); and a pair of transfer guides (20) configured to form a transfer conveyance path on which a banknote is conveyed between the first unit (10) and the second unit (30). The transfer conveyance path is formed between the pair of transfer guides (20). The transfer guide (20) has a first edge (26) at an opposite side to the transfer conveyance path and at the first unit (10) side, the first edge (26) coming closer to the transfer conveyance path as the first edge (26) nears an end at the first unit (10) side.
