Banknote Storing and Issuing Module With Pivoted Lever Arms
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, limiting the outer diameter variation of the storage roller, which affects the number of banknotes that can be stored.
Innovation Solution
A storing and issuing module with a unique mechanical layout that includes a storage roller, transport tape, and lever arms with pivoted axes, allowing the conveying section to maintain a consistent banknote path despite significant variations in the storage roller's outer diameter, enabling a larger storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the storage roller outer diameter is increased to store more banknotes, then the storage capacity is improved, but the maximum distance constraint on holding means engagement is violated
Solution Approach 1:
The patent applies dynamics by making the conveying section movable and adaptable. The lever arms with pivoted axes allow the conveying section to dynamically adjust its position and orientation in response to changes in storage roller outer diameter, maintaining proper holding means engagement across a wide range of storage capacities
Solution Approach 2:
The patent changes geometric parameters of the conveying section through the lever arm mechanism. As the storage roller outer diameter varies, the lever arms pivot to alter the conveying section's effective length and angle, thereby maintaining the critical engagement distance parameter within acceptable limits despite large changes in storage capacity
2Quantity of substance
If the storage roller outer diameter varies significantly to increase storage capacity, then more banknotes can be stored, but the banknote conveying path consistency deteriorates
Solution Approach 1:
The lever arms create a dynamic conveying section that automatically adapts to storage roller diameter changes. The pivoted axes allow the conveying section to maintain a consistent effective path length and orientation, ensuring stable banknote conveying performance across varying storage capacities
Solution Approach 2:
The lever arms act as intermediary elements between the storage roller and the fixed module structure. They mediate the effect of storage roller diameter variations by transforming these changes into controlled positional adjustments of the conveying section, isolating the conveying path from direct impact of roller size changes
3Ease of manufacture
If the module design is simplified to reduce cost, then manufacturing ease is improved, but the storage capacity is limited
Solution Approach 1:
The patent uses a relatively simple mechanical lever arm mechanism with pivoted axes to achieve dynamic adaptation. This straightforward mechanical design avoids complex systems while still enabling the conveying section to adjust to large variations in storage roller diameter, thereby achieving high storage capacity with manufacturing simplicity
Solution Approach 2:
The lever arm mechanism serves multiple functions: it positions the conveying section, maintains engagement distance, and adapts to varying storage roller diameters. This multi-functionality allows a single relatively simple mechanical structure to handle a wide range of storage capacities without requiring multiple specialized components
