Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote acceptors and validators face challenges in efficiently processing multiple banknotes at once, particularly in receiving a bundle of banknotes, as existing bulk feeder modules require complex components and do not allow for mid-operation additions to the bundle.
Innovation Solution
A banknote feeder device with eccentrically mounted transport wheels, a pinch point mechanism using a protrusion and resiliently biased guide members, and a feed wheel arrangement that facilitates the singulation of banknotes from a bundle, enabling continuous operation without the need for complex feeder pinch arms and pulleys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional bulk feeder module is used to receive banknotes in bundle form, then the apparatus can process multiple banknotes at once, but the device complexity increases due to requiring feeder pinch arms, pulleys, and stripper belts
Solution Approach 1:
The patent extracts and eliminates the complex feeder pinch arm, pulley, and stripper belt components from the bulk feeder module. Instead, it uses a simplified transport mechanism with wheels that move along a transport path, removing unnecessary components while maintaining the ability to process banknotes in bundles
Solution Approach 2:
The transport wheels serve multiple functions: they transport banknotes through the apparatus, apply friction to singulate individual banknotes from the bundle, and control the flow of banknotes without requiring separate dedicated components for each function
2Productivity
If a conventional bulk feeder module is used, then banknotes can be fed through the apparatus, but the user cannot add more banknotes to the bundle during operation
Solution Approach 1:
The patent implements a dynamic transport mechanism where the transport wheels can accommodate varying bundle sizes. The wheels apply friction-based control that adapts to the number of banknotes present, allowing the system to handle both initial bundle loading and mid-operation additions seamlessly
Solution Approach 2:
The transport mechanism maintains continuous operation capability by allowing users to add banknotes to the bundle during processing. The system continuously monitors and adjusts the transport of banknotes through the apparatus without interruption, maintaining productive flow
3Ease of operation
If a feeder pinch arm arrangement is used to exert downward pressure on the banknote bundle, then banknotes can be singulated and transported, but the device complexity and mechanical complexity increase
Solution Approach 1:
The patent replaces the mechanical pinch arm pressure system with a friction-based wheel transport system. Instead of using complex mechanical arms to apply downward pressure, the transport wheels use rotational friction to singulate and move banknotes, significantly simplifying the mechanical arrangement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient processing of multiple banknotes by simplifying the mechanism, allowing for continuous operation and mid-operation additions, reducing the complexity of components and improving the handling of banknote bundles.
Implementation Method 1
A high friction drive pulley operating in conjunction with one or more stripper belts ensures that only a single banknote enters the transport path
Implementation Method 2
The protrusion is located between a pair of resiliently biased guide members
