Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing media handling systems in Self Service Terminals (SSTs) face issues with media items like banknotes and cheques becoming crumpled or folded, leading to jams, reduced storage density, and increased downtime due to deviations from the transport pathway, which affects the efficiency and accuracy of deposit and withdrawal processes.

Innovation Solution

The implementation of biased deforming members that adjust the shape of media items based on their direction of travel, ensuring they are properly aligned and stored, using abutment surfaces and biasing elements to maintain or change the shape as they enter or exit storage zones.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If media items are transported bidirectionally along a pathway, then the same transport mechanism can be used for both directions, but the media items may become crumpled or folded due to lack of directional adaptation

Engineering Contradiction:

Improvebidirectional transport capabilityVSAvoidmedia item integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The biased deforming member is designed to dynamically change its state based on the direction of media item transport. When a media item is transported towards the predetermined location, the biased deforming member deforms the media item to optimize its shape for storage. When transported away, the member returns to its initial state, allowing the media item to maintain its original shape. This dynamic adaptation ensures media item integrity while enabling bidirectional transport.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the physical parameter (shape) of the media item based on transport direction. The biased deforming member alters the media item's shape characteristics selectively: deforming it when moving towards the storage location and maintaining its natural shape when moving away. This parameter change resolves the contradiction by adapting the media item's physical state to the transport direction.

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If the biased deforming member deforms media items towards the predetermined location, then storage density increases, but the device complexity increases due to additional components

Engineering Contradiction:

Improvestorage densityVSAvoidnumber of deforming components

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The biased deforming member is designed to perform multiple functions: it acts as a deformation element when media items are transported towards the predetermined location, and as a non-intrusive element when transported away. This multi-functionality allows a single component to serve dual purposes, increasing storage density without proportionally increasing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The biased deforming member automatically adjusts its state based on the presence and direction of media item transport without requiring external control mechanisms. The biasing element causes the member to self-adjust between deformed and non-deformed states, eliminating the need for complex control systems and reducing overall device complexity while maintaining high storage density.

Inventive Principle:

Principle #25Self-service

3Productivity

If media items are allowed to maintain their natural shape during transport, then the transport pathway remains clear, but storage efficiency decreases due to improper alignment

Engineering Contradiction:

Improvetransport flow efficiencyVSAvoidstorage alignment precision

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The biased deforming member performs preliminary deformation of the media item during the transport process towards the predetermined location. This preliminary action prepares the media item for optimal storage alignment before it reaches the storage position, ensuring both smooth transport flow and precise storage alignment without requiring additional correction mechanisms.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method and apparatus for determining at least one characteristic of a media item during transport of the media item are disclosed. The method comprises via at least one biased deforming member disposed in a first state, deforming a media item thereby providing the media item as an incoming media item having a first characteristic, if the media item is transported towards a predetermined location; and via the biased deforming member disposed in a further state, providing a media item as an outgoing media item having a further characteristic if the media item is transported away from the predetermined location.
