Rotary Media Storage Unit for Multi-Denomination Banknote Recyclers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote recyclers face high costs and low reliability due to the need for multiple pathways and storage components to handle different denominations, which is a challenge for applications requiring low-cost and reliable solutions, such as the retail and vending industries.
Innovation Solution
A media storage unit for a media recycler featuring a pair of rotary storage devices with calibration marks on storage tapes, a sensor to detect these marks, and a controller to manage the movement of storage tapes and a pivoting gate for efficient storage and retrieval of banknotes, allowing for dynamic flexibility in storing multiple denominations without the need for extensive infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pathways and storage components are used to handle different denominations, then the recycler can store and retrieve multiple denominations, but the cost increases and reliability decreases
Solution Approach 1:
The patent merges multiple denomination storage into a single storage unit with a rotary mechanism. Different denominations are stored in different sectors of the same rotary storage unit, eliminating the need for separate pathways and storage components for each denomination. This reduces device complexity while maintaining the ability to handle multiple denominations.
Solution Approach 2:
The rotary storage unit serves multiple functions: it stores multiple denominations, retrieves them on demand, and transitions between different denomination sectors. This universal component replaces what would traditionally require multiple specialized storage pathways, reducing overall system complexity.
2Adaptability or versatility
If multiple pathways and storage components are used to handle different denominations, then the recycler can store and retrieve multiple denominations, but the cost increases
Solution Approach 1:
The patent combines multiple denomination storage capabilities into a single rotary storage unit, reducing the total number of components that need to be manufactured and assembled. This merging approach lowers manufacturing costs while maintaining multi-denomination handling capability.
Solution Approach 2:
The rotary storage unit is designed as a universal component that can store and retrieve multiple denominations, eliminating the need to manufacture and install separate specialized storage systems for each denomination, thereby reducing overall manufacturing cost.
3Adaptability or versatility
If multiple pathways and storage components are used to handle different denominations, then the recycler can store and retrieve multiple denominations, but the reliability decreases
Solution Approach 1:
The patent merges multiple denomination storage into a single rotary storage unit with a common access pathway. This reduces the number of potential failure points associated with multiple separate pathways and components, thereby improving system reliability while maintaining multi-denomination capability.
Solution Approach 2:
The rotary storage unit functions as a reliable universal storage mechanism for multiple denominations. By using a single well-engineered rotary mechanism rather than multiple separate pathways, the system achieves higher reliability through reduced component count and simplified mechanics.

AI summary
A media storage unit (10) for a media recycler is described. The media storage unit (10) comprises: a first rotary storage device (12); a second rotary storage device (14) aligned with the first rotary storage device (12); and storage tape (16) wound around each of the first and second storage devices (12,14) and including calibration marks (96) disposed along one side of the storage tape (16). The media storage unit (10) also comprises a sensor (52) for detecting the calibration marks (96); an entry/exit port (40) between the first and second rotary storage devices (12,14) through which media items can be inserted or removed; and a controller (54) operable to rotate the first and/or second storage devices (12,14) to move the storage tape (16) forwards or backwards while sensing the calibration marks (96) to locate either (i) a media item of the desired type for a dispense transaction, or (ii) a space on the storage tape (16) of the required type for a deposit transaction.
