ATM Annular Banknote Channel Unidirectional Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic teller machines face issues with jamming during banknote conveyance due to bidirectional movement in conveyance channels, which affects processing efficiency.
Innovation Solution
The banknote-in, temporary storage, banknote-out, and identification mechanisms are connected to an annular channel, allowing banknotes to move unidirectionally, reducing the likelihood of jamming and improving processing efficiency by enabling efficient circulation between these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If bidirectional conveyance channel is used for banknote deposit and withdrawal operations, then the channel structure is simplified and space is saved, but the probability of jamming increases and processing efficiency decreases
Solution Approach 1:
The conveyance system is segmented into two separate channels: a first conveyance channel dedicated to banknote deposit operations and a second conveyance channel dedicated to banknote withdrawal operations. This segmentation eliminates the interference between bidirectional banknote flows, preventing jamming while maintaining efficient processing in both operations simultaneously.
2Device complexity
If bidirectional conveyance channel is used for banknote deposit and withdrawal operations, then the channel structure is simplified and space is saved, but the jamming probability increases
Solution Approach 1:
The conveyance system is segmented into a first conveyance channel for deposit operations and a second conveyance channel for withdrawal operations. This physical separation ensures that banknotes moving in opposite directions do not interfere with each other, eliminating the root cause of jamming and significantly improving system reliability.
Solution Approach 2:
A switching mechanism acts as an intermediary control system that directs banknotes into the appropriate conveyance channel based on the operation type (deposit or withdrawal). This intermediary ensures that each channel handles only its designated operation, preventing conflicts and jamming while maintaining a relatively compact overall structure.

AI summary
An automatic teller machine includes a banknote conveyance channel, a banknote recycling channel, and a banknote circulation channel. The banknote conveyance channel includes an annular channel, a first branch channel, a second branch channel, a third branch channel, a fourth branch channel, and a fifth branch channel. A banknote-in mechanism communicates with the annular channel via the first branch channel. A temporary storage mechanism communicates with the annular channel via the second branch channel. A banknote-out mechanism communicates with the annular channel via the third branch channel. Two ends of an identification mechanism communicate with the annular channel via the fourth branch channel and the fifth branch channel, respectively. A recycling box communicates with the banknote conveyance channel via the banknote recycling channel. A circulation box communicates with the banknote conveyance channel via the banknote circulation channel.
