Voucher Handling Device Jam Management via Preliminary Inventory Booking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for handling notes of value, such as ATMs, face difficulties in efficiently managing note jams during deposit operations, leading to complex data processing and reduced functionality, as they lack proper inventory tracking for reject cassettes and are not designed to handle jams occurring during deposit scenarios.
Innovation Solution
The solution involves increasing the inventory counter of the affected cash cassette and reducing it along with increasing the reject counter when a note jam occurs, allowing notes to be directly transported to the reject cassette without first going to a cash cassette, and processing these notes as if they were part of a regular deposit followed by an incorrect withdrawal, thus simplifying data processing and maintaining device functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If notes of value are transported directly to the reject cassette during deposit without first going to a cash cassette, then the handling of note jams is simplified, but the inventory tracking becomes inaccurate
Solution Approach 1:
The control unit performs preliminary actions by first increasing the inventory counter of the target cash cassette before transporting notes directly to the reject cassette. This preliminary booking ensures that the inventory tracking remains accurate even though the notes bypass the cash cassette physically, resolving the contradiction between simplified handling and accurate tracking.
2Reliability
If a cash cassette is decommissioned to handle jammed notes, then the notes can be processed, but the number of available cash cassettes is reduced and device functionality is limited
Solution Approach 1:
The control unit acts as an intermediary by managing the inventory counters to reflect the temporary assignment of jammed notes to a cash cassette, even though the notes are physically transported directly to the reject cassette. This allows the cash cassette to remain commissioned and functional while still handling the jammed notes appropriately.
3Ease of manufacture
If existing software standards are used without changes, then programming interfaces remain compatible, but the inventory of jammed notes during deposit cannot be determined
Solution Approach 1:
The control unit performs preliminary booking of the jammed notes in the inventory counter of the target cash cassette before the notes are physically transported to the reject cassette. This preliminary action ensures that inventory information is captured and tracked using existing software standards, preventing information loss while maintaining software compatibility.

AI summary
The invention relates to a device (10) for handling banknotes, comprising an input and output unit (16), a control unit (20), at least one cash box (22 to 28), a reject cassette (30), and a transport unit. The cash box (22 to 28) is equipped with a stock counter (52 to 58) indicating the current stock of banknotes in the cash box and a reject counter (62 to 68) indicating the number of banknotes removed from the cash box (22 to 28) and fed into the reject cassette (30).When a banknote jam occurs during the transport of at least one deposited banknote from the input and output unit (16) to the cash box (22 to 28), in a first step the value of the stock counter (52 to 58) of the cash box (22 to 28) is increased by the number of banknotes in the jam, before in a second step the value of the stock counter (52 to 58) is reduced by the number of banknotes in the jam and the value of the reject counter (62 to 68) is increased by the number of banknotes in the jam.
