Banknote Handling Machine Segmented Depositories
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote handling machines face issues with paper jamming due to the mixing of banknotes of different types and sizes in a single depository, leading to inefficiencies and processing delays.
Innovation Solution
A banknote handling machine with a distinguishing unit that classifies banknotes by type, outer size, and condition, and a controller that directs them to corresponding depositories and housing units, ensuring each unit is sized appropriately to prevent jamming and optimize processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If banknotes of multiple money types are accumulated and housed in a single depository, then the depository can handle diverse banknote types, but paper jamming occurs due to mixing banknotes of different outer sizes
Solution Approach 1:
The patent divides the single depository into multiple depositories, with each depository dedicated to housing banknotes of a specific money type. This segmentation prevents mixing of banknotes with different outer sizes, thereby eliminating paper jamming while maintaining the ability to handle diverse banknote types through the coordinated use of multiple specialized depositories.
2Adaptability or versatility
If the depository housing space is set in accordance with banknotes having the largest outer size, then all types of banknotes can be housed, but small banknotes are accumulated in various positions causing jamming
Solution Approach 1:
The patent assigns different housing space dimensions to different depositories based on the specific outer size requirements of each money type. Instead of using a uniform large space for all banknotes, each depository is optimized with appropriate housing space for its designated banknote type, ensuring proper accumulation and preventing jamming of small banknotes.
3Device complexity
If a single depository is used for accumulating banknotes before transaction determination, then the system structure is simple, but processing efficiency decreases due to jamming and rehandling
Solution Approach 1:
The patent implements multiple depositories organized according to money types, which initially increases structural complexity. However, this segmentation eliminates paper jamming and the need for rehandling, thereby significantly improving processing speed and productivity. The systematic organization of banknotes by type streamlines the overall processing flow.
4Reliability
If banknotes are classified by money type before housing, then jamming is prevented, but the system requires multiple depositories increasing complexity
Solution Approach 1:
The patent designs each depository as a multi-functional unit that can handle various operations (accumulation, temporary storage, and transfer) for its designated money type. This universal design allows the system to achieve reliable jamming-free operation through money type classification while minimizing the increase in overall system complexity by making each depository versatile.

AI summary
A banknote handling machine includes: a distinguishing unit that distinguishes a given classifying condition covering the type according to which banknotes from multiple types of banknotes that are put in are classified; a plurality of depositories in corresponding ones of which the banknotes whose type is distinguished by the distinguishing unit are classified and housed according to the classifying condition before a transaction relating to the put-in banknotes is determined; a plurality of housing units in corresponding ones of which the banknotes that are sent from the corresponding depositories are classified and housed according to the classifying condition after the transaction is determined; and a controller that controls the depositories according to the classifying condition.
