Banknote Storage Roller Layout for Large-Capacity Issuing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote storage and issuing modules have limited storage capacity due to constraints on the maximum distance that holding means can engage banknotes, leading to inefficient handling of varying banknote denominations and sizes, especially when the storage roller diameter significantly changes with full or empty conditions.
Innovation Solution
A storing and issuing module design featuring a unique conveying section layout with lever arms and pinch-rollers that adapt to the varying outer diameter of the storage roller, ensuring consistent banknote conveyance channels and allowing for a larger storage capacity by minimizing diameter variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the storage roller diameter is increased to accommodate more banknotes, then the storage capacity is improved, but the variation in outer diameter between full and empty conditions worsens, affecting the consistency of the conveying section
Solution Approach 1:
The patent applies the dynamics principle by making the conveying section adaptable to varying storage roller diameters. The conveying section includes adjustable components that can dynamically reposition themselves according to the roller's outer diameter, whether full or empty. This allows the system to maintain consistent banknote conveyance functionality despite significant diameter variations, resolving the contradiction between increased storage capacity and conveying section stability.
2Reliability
If the maximum distance for holding means engagement is constrained to ensure proper banknote handling, then the reliability of banknote processing is improved, but the storage capacity is limited
Solution Approach 1:
The patent applies the dimensionality change principle by reconfiguring the spatial arrangement of the conveying section and holding means. Instead of being limited to a single fixed distance constraint, the system utilizes multiple dimensions and adjustable positions within the conveying path. This allows the holding means to engage banknotes at optimal points while the conveying section adapts to maximize storage capacity, breaking the direct trade-off between reliability and capacity.
