Cash Transaction Device Banknote Storage Width Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cash automatic transaction devices face issues with paper jams and poor posture of banknotes due to conflicting requirements for the width of the depositing/dispensing port and reflux box, leading to instability during storage and transfer.
Innovation Solution
The device features a depositing/dispensing port with a depositing/dispensing space narrower than the reflux box's exit and entrance width, and an accumulation space wider than the reflux box's exit and entrance width, ensuring proper alignment and preventing jams or poor posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the storage width of the depositing/dispensing port is made equal to or greater than the exit and entrance width of the reflux box, then banknotes can be stored without paper jam, but banknotes set in biased position or badly skewed may cause paper jam or poor posture upon storage in the reflux box
Solution Approach 1:
The depositing/dispensing port is divided into two distinct spaces: a depositing/dispensing space with width equal to or smaller than the reflux box exit/entrance width, and an accumulation space with width greater than the reflux box exit/entrance width. This segmentation allows different functional requirements to be met in different zones, resolving the contradiction between storage reliability and operation stability.
Solution Approach 2:
Different width characteristics are assigned to different regions within the depositing/dispensing port. The depositing/dispensing space has a narrower width to ensure proper alignment during transfer, while the accumulation space has a wider width to accommodate various banknote positions and orientations. This local differentiation resolves the contradiction by providing appropriate width characteristics in each specific location.
2Reliability
If the storage width of the depositing/dispensing port is made equal to or smaller than the exit and entrance width of the reflux box, then banknotes can be transferred without paper jam, but banknotes set in biased position or badly skewed may cause paper jam or poor posture upon accumulation in the depositing/dispensing port
Solution Approach 1:
The depositing/dispensing port is segmented into two spaces with different width characteristics. The depositing/dispensing space has width equal to or smaller than the reflux box exit/entrance width to ensure reliable transfer, while the accumulation space has greater width to maintain banknote posture stability during accumulation, resolving the contradiction between transfer reliability and posture stability.
Solution Approach 2:
Different width characteristics are provided in different locations: the depositing/dispensing space has narrower width for reliable transfer, while the accumulation space has wider width for posture stability. This local quality differentiation resolves the contradiction by addressing each requirement in its appropriate spatial zone.

AI summary
A cash automatic transaction device 1 capable of, upon storage of a banknote sent from a depositing/dispensing port 100 in a banknote storage box, or upon accumulation of a banknote sent from the banknote storage box in the depositing/dispensing port 100, preventing the occurrence of trouble such as paper jam or poor posture. The cash automatic transaction device 1 has a depositing/dispensing port used for depositing/dispensing of banknotes, and a banknote storage box for storage of deposited/dispensed banknotes. The depositing/dispensing port 100 has depositing/dispensing space to store the deposited/dispensed banknotes, and accumulation space in which the banknote is accumulated upon dispensing. The width of the depositing/dispensing space is smaller than the exit and entrance width of the storage box, while the width of the accumulation space is greater than the exit and entrance width of the storage box.
