Solution Overview

Problem

Existing devices for handling notes of value, such as automatic cash registers and ATMs, face inefficiencies in maximizing the capacity of note cassettes due to the need to shift stacks of notes, reducing available space and limiting the number of notes that can be accommodated.

Innovation Solution

The feed module moves the retaining element along a path angled to the stacking direction, allowing notes to be fed into the cassette without pressing the stack deeper, thus optimizing the use of available space and enabling more notes to be stored without altering the cassette dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the retaining element is positioned to hold the stack of notes in the receiving area, then the notes are securely retained, but the contact area of the retaining element reduces the available space for storing notes

Engineering Contradiction:
Improveretention of notesVSAvoidavailable space in receiving area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The retaining element is moved along a travel path that is angled relative to the stacking direction, transitioning from a position where it contacts the notes in the receiving area to a feed position where it is adjacent to the feed area. This dimensional change in positioning allows the retaining element to perform its retention function without permanently occupying space in the receiving area, thereby resolving the contradiction between secure retention and available storage space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The retaining element is made movable along a defined travel path between a retaining position and a feed position. This dynamic positioning allows the system to optimize space utilization by moving the retaining element out of the way during feeding operations while maintaining its retention function when needed, thus resolving the space contradiction.

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If the retaining element is moved along a path angled to the stacking direction, then the available space is optimized, but the mechanism complexity increases

Engineering Contradiction:
Improveavailable space in receiving areaVSAvoidfeed module mechanism
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The retaining element serves multiple functions: it retains notes in the receiving area, guides notes during feeding, and can be positioned in different locations along its travel path. This multi-functionality justifies the added mechanism complexity by eliminating the need for separate retention and feeding components, thereby optimizing space while maintaining functional efficiency.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If the entire stack of notes is shifted by the length of the contact areas of the retaining elements, then the notes can be fed, but the maximum capacity of the cassette is reduced

Engineering Contradiction:
Improvefeeding of notesVSAvoidnumber of notes accommodated
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

Instead of shifting the entire stack of notes in the stacking direction by the length of the retaining element contact areas, the retaining element itself is moved along an angled travel path to a feed position. This dimensional change in the retention mechanism's positioning allows notes to be fed without reducing the cassette capacity, as the retaining element does not need to be as long as the stack shift distance would require.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The invention relates to a device (10) for handling value notes, comprising a feed module (1000) for feeding value notes to a value note receiving region (1004) of a value note cassette (16a to 16d), wherein the value notes can be received in the value note receiving region (1004) in the form of value note stacks (1006). The feed module (1000) comprises at least one retaining element (1008, 1010), which in a retaining position makes contact with an end-face value note of the value note stack (1006) and holds the value note stack (1006) in the value note receiving region (1004). In a feeding position, the retaining element (1008, 1010) is arranged such that a value note can be fed to the value note stack (1006). The retaining element (1008, 1010) can be moved along a movement path obliquely to the stacking direction (P3), in which a value note that is to be fed to the value note stack (1006) is fed to the value note stack (1006), from the retaining position into the feeding position, and vice versa.
