Solution Overview

Problem

Conventional media item presenters, such as banknote presenters in ATMs, are unable to accurately stack different sizes and types of banknotes due to fixed registration device components, leading to splayed stacks, jams, and increased downtime.

Innovation Solution

A registration device with movable and pivotable registration members that adjust to accommodate varying banknote sizes, allowing for precise control of the flight and stacking of media items, reducing the risk of jams and space envelope requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed registration members are used in the registration device, then the device structure is simple, but different sizes and types of banknotes cannot be accurately stacked

Engineering Contradiction:

Improveability to accommodate varying banknote sizesVSAvoidregistration device structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The registration device incorporates movable registration members that can adjust their positions dynamically. The first registration member is movable relative to the base member, and the second registration member is movable relative to the first registration member, allowing the device to adapt to different banknote sizes while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The registration device is divided into multiple independent registration members (first registration member, second registration member) that can move independently. This segmentation allows each component to contribute to the overall adaptability without requiring complete redesign of the entire registration device structure.

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If fixed distance between flight limiting fingers and registration edge members is used, then the device is compact, but banknotes of different sizes cannot be neatly stacked

Engineering Contradiction:

Improvestacking accuracy of media itemsVSAvoidspace envelope of registration device

Core Design Contradiction:

Manufacturing precisionVSVolume of moving object

Solution Approach 1:

The distance between flight limiting fingers and registration edge members is made dynamic through movable registration members. The first registration member can move closer to or farther from the base member, and the second registration member can move relative to the first, enabling precise control over the stacking distance for banknotes of various sizes without requiring a large fixed space envelope.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The registration device changes the physical parameters (positions and distances) of its registration members dynamically. By adjusting the positions of the first and second registration members, the device optimizes the spacing parameters for different banknote dimensions, achieving high stacking precision while maintaining compact overall dimensions.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If conventional registration device is used, then the device is simple, but splayed stacks and jams occur with different banknote sizes

Engineering Contradiction:

Improvereduction of jams and downtimeVSAvoidregistration device mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The movable registration members enable the device to maintain reliable operation with different banknote sizes by dynamically adjusting to prevent splayed stacks and jams. The ability to move the first and second registration members ensures proper alignment and containment of banknotes during stacking, reducing errors and downtime.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The registration device is designed to handle multiple types and sizes of banknotes using the same basic structure with movable components. The first and second registration members can be positioned to accommodate various banknote dimensions, making the device universally applicable while maintaining simplicity through reuse of the same mechanical components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The present invention provides apparatus for stacking media items, comprising a base member for supporting a stack of media items, at least one first registration member extending generally upwardly with respect to the base member, and at least one further registration member extending generally upwardly with respect to the base member and spaced apart from the first registration member, wherein at least a one of the first and further registration members is selectively moveable towards or away from a remainder one of the first and further registration members in an input direction of the media items. A method of stacking media items is also provided.
