Dynamic Storage Roller Module for Banknote Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote storage and dispensing systems are inefficient due to the varying circulation statistics of different denominations, leading to suboptimal use of storage space and potential issues of modules becoming full or empty, especially when handling multiple currencies and denominations with different circulation rates.
Innovation Solution
A storing and issuing module with two storage rollers, each equipped with sensors to monitor instant storage capacity, and a transport tape system that dynamically adjusts to the diameter of the rollers, ensuring optimal space usage by maintaining anti-friction gaps and allowing the rollers to adapt their size relative to each other, thereby optimizing storage capacity based on real-time needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple storage modules with fixed capacities are used to handle different banknote denominations, then the equipment can store various types of banknotes, but the storage space is not optimally utilized because circulation statistics vary significantly between denominations
Solution Approach 1:
The patent implements dynamic storage capacity by allowing the storage roller to rotate in and out of the module. When a banknote denomination requires more storage capacity, the roller rotates to increase the storage volume. This dynamic adjustment resolves the contradiction by enabling the same module to adapt to varying circulation demands while optimizing storage space utilization across different denominations.
Solution Approach 2:
The invention changes the storage capacity parameter of the module by rotating the storage roller to different positions. This parameter change allows the module to store different quantities of banknotes based on circulation statistics, thereby optimizing space utilization while maintaining versatility for handling multiple denominations.
2Quantity of substance
If the storage module is designed with large capacity to handle high-circulation denominations, then it can meet high storage demands, but it becomes inefficient for low-circulation denominations that require only small storage space
Solution Approach 1:
The dynamic roller mechanism allows the storage capacity to be adjusted based on the specific denomination being stored. For high-circulation denominations, the roller is positioned to maximize storage capacity. For low-circulation denominations, the roller is positioned to minimize space occupation, thereby maintaining high storage efficiency across all denominations.
3Quantity of substance
If separate modules are added for each denomination to ensure adequate storage capacity, then each denomination has sufficient storage space, but the equipment becomes more expensive and occupies more space
Solution Approach 1:
The patent makes a single storage module universal by enabling it to handle multiple denominations through the rotatable roller mechanism. This multi-functionality eliminates the need for separate dedicated modules for each denomination, reducing device complexity and equipment cost while ensuring adequate storage capacity for all denominations.
Solution Approach 2:
The invention merges the functionality of multiple denomination-specific modules into a single multi-functional module. By combining storage capacities dynamically through the rotatable roller, the system achieves the equivalent of multiple separate modules without the associated complexity and cost.
4Area of stationary object
If the module size is reduced to save space, then the equipment becomes more compact, but the storage capacity is insufficient for high-circulation denominations
Solution Approach 1:
The dynamic roller allows the module to maintain a compact footprint when storing low-circulation denominations while expanding storage capacity when needed for high-circulation denominations. This dynamic adjustment resolves the contradiction between compact size and sufficient storage capacity.

AI summary
A double storing and issuing device (11) for two banknotes denomination (12) and/or other flexible documents, for use in an equipment for the automatic processing of banknotes, where each storing and issuing device includes a storage roller (50a, 50b), relative motor (60a, 60b), at least a transport tape (52a, 52b) provided for wrapping on the storage roller together with the banknotes (12). The two storage rollers (50a, 50b) can share the space between them because the transport tape (52a), tensioned by storage roller motor (60a) and feeding-roller (51a), pushing against accompanying rollers (74a) strictly follows storage roller (50a) diameter. The double storing and issuing device (11) comprises an electronic unit (65) for the storage roller motors (60a, 60b) and relative transport tapes (52a, 52b) revolution sensors (67a, 67b), that provides a device full status as any possible combination of storage roller (50a, 50b) diameter plus a minimum gap to avoid mechanical reciprocal interferences.
