Solution Overview

Problem

Existing medium transferring apparatuses in financial devices often result in uneven stacking and potential damage of media due to misalignment during transfer, leading to degraded efficiency and damage.

Innovation Solution

Incorporation of side guides, transfer rollers, aligning rollers, and transfer belts that rotate in different directions to align and guide media along the transferring path, preventing misalignment and ensuring even stacking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the medium transferring path has a width and height sufficiently greater than the medium dimensions to prevent damage, then medium damage is reduced, but medium alignment precision deteriorates causing uneven stacking

Engineering Contradiction:
Improvemedium damageVSAvoidmedium alignment precision
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The medium transferring apparatus is divided into multiple functional sections: a medium introduction section with a first medium guide, a transfer section with transfer rollers, and a stacking section with a second medium guide. This segmentation allows each section to perform its specific function optimally - the first guide introduces media without constraint, the transfer rollers move media, and the second guide ensures precise alignment during stacking, thereby resolving the contradiction between preventing damage and ensuring alignment precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Transfer rollers are introduced as intermediary elements between the medium introduction section and the stacking section. These rollers act as mediators that transfer media while maintaining control over their position and orientation. The rollers enable precise alignment during transfer without requiring the entire transferring path to be tightly constrained, thus preventing both damage and ensuring alignment precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If transfer rollers are used to transfer medium one by one, then transfer automation is improved, but stacking efficiency deteriorates due to misalignment

Engineering Contradiction:
Improvetransfer automationVSAvoidstacking efficiency
Core Design Contradiction:
Extent of automationVSProductivity

Solution Approach 1:

The first medium guide in the introduction section performs preliminary alignment of media before they enter the transfer section. This preliminary action ensures that media are properly oriented and positioned before the automated transfer process begins, preventing misalignment during transfer and subsequent stacking inefficiencies, thereby maintaining both automation and stacking efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The second medium guide in the stacking section provides feedback alignment by ensuring that transferred media are precisely positioned before stacking. This feedback mechanism corrects any minor misalignments that occur during transfer, ensuring efficient stacking while maintaining the automated transfer process, thus resolving the contradiction between automation and stacking efficiency.

Inventive Principle:
Principle #23Feedback
