Banknote Storage Drum with Opposed Webs for Compact Multi-Currency Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote storage and dispensing apparatuses are bulky and expensive due to the need for multiple reels, making them unsuitable for compact spaces like gambling machines, and require frequent restocking with security risks.
Innovation Solution
A compact apparatus using rotatable drums with opposed webs for storing and dispensing banknotes, featuring a diverter mechanism and processing means to determine note characteristics, allowing mixed denomination storage and efficient space use, along with tensioning and drive mechanisms for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple reels are used to store different denominations of banknotes, then the apparatus can store and dispense multiple currencies, but the apparatus becomes bulky and expensive
Solution Approach 1:
The patent combines multiple denomination storage functions into a single drum by winding different denominations of banknotes along the length of a single web. This merging approach eliminates the need for multiple separate reels, significantly reducing the apparatus volume while maintaining multi-currency storage capability.
Solution Approach 2:
The single drum structure serves multiple functions by storing various denominations of banknotes simultaneously on different sections of the web. The drum can dispense any denomination by rotating to the appropriate position, making it a universal storage solution that replaces multiple specialized reels.
2Adaptability or versatility
If multiple reels are used for different denominations, then notes can be stored according to denomination, but the number of mechanical components increases making the apparatus expensive
Solution Approach 1:
Multiple denomination storage functions are merged into a single drum structure with a linear web. Instead of having separate mechanical reels for each denomination, the patent uses one drum with positional encoding to achieve the same functionality, dramatically reducing the number of mechanical components.
Solution Approach 2:
The patent replaces complex mechanical identification systems with an optical/electronic encoding system. Barcodes or other machine-readable indicators on the web provide denomination information, eliminating the need for complex mechanical sensors and actuators that would be required in a multi-reel system.
3Volume of moving object
If notes are stored on a single drum along the web length, then the apparatus becomes compact, but the diverter mechanism must precisely control note dispensing
Solution Approach 1:
The patent replaces complex mechanical diverter mechanisms with an optical/electronic control system. Barcodes or machine-readable indicators on the web enable automated identification and positioning of different denominations, allowing precise control of note dispensing without complex mechanical diverters.
Solution Approach 2:
The web itself carries the information (via barcodes or indicators) needed to control its own dispensing. The system reads the encoding on the web and automatically positions and dispenses the correct denomination, eliminating the need for external mechanical control mechanisms.
