Vane Wheel With Flexible Membrane for Banknote Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote storage systems require additional feeding and separating elements that increase weight and transport costs, while also occupying space that could be used for storage, and these elements must be accurately positioned to ensure reliable banknote transport.
Innovation Solution
A single sheet handling device with a vane wheel system that includes flexible and rigid areas to guide and press banknotes into a container, reducing the need for additional pressure elements and allowing for efficient stacking and separation of banknotes by increasing the contact area between the vanes and the banknotes, thus minimizing fluttering and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If feeding and separating elements are arranged in the banknote storage container, then reliable banknote transport into and out of the container is enabled, but the weight of the container increases and transport expenses are increased
Solution Approach 1:
The feeding and separating elements are segmented from the container itself and placed on separate carriers. This allows the container to be lightweight and simple, while the feeding/separating functionality is provided by removable carrier units that can be exchanged as needed.
Solution Approach 2:
The feeding and separating elements are extracted from the container structure and placed on separate carriers. This extraction eliminates the weight penalty from the container itself, allowing the container to be optimized for storage capacity while feeding/separating functions are provided by external, removable components.
2Reliability
If feeding and separating elements are arranged in the banknote storage container, then reliable banknote transport into and out of the container is enabled, but space is occupied that can no longer be used for banknote storage
Solution Approach 1:
The feeding and separating elements are segmented from the container and placed on separate carriers. This segmentation allows the container interior to be fully utilized for banknote storage, while the feeding/separating functionality is provided by external carrier units that do not encroach on storage space.
Solution Approach 2:
The feeding and separating elements are extracted from the container structure and placed on separate carriers. This extraction maximizes the container's internal volume for banknote storage while maintaining the necessary feeding and separating functions through external components.
3Reliability
If feeding and separating elements are arranged in the banknote storage container, then reliable banknote transport into and out of the container is enabled, but the device complexity increases
Solution Approach 1:
The system is segmented into a simple container and separate carriers with feeding/separating elements. This segmentation simplifies the container structure while maintaining reliable banknote transport through the modular carrier units that can be independently optimized and replaced.
Solution Approach 2:
The complex feeding and separating elements are extracted from the container and placed on separate carriers. This extraction simplifies the container to a basic storage structure, while the complexity is concentrated in the removable carrier units that can be exchanged without affecting the container itself.
4Manufacturing precision
If the contact area between the vane wheel and the banknote stack is increased, then banknote positioning accuracy is improved and fluttering is reduced, but the device complexity increases
Solution Approach 1:
The vane wheel incorporates a flexible membrane that can conform to the banknote stack surface, increasing the contact area without requiring complex mechanical structures. The flexibility of the membrane allows it to adapt to variations in banknote stacking while maintaining consistent contact pressure and positioning accuracy.
Solution Approach 2:
The vane wheel design changes the physical state of the contact surface from rigid to flexible, allowing the material to deform and increase contact area with the banknote stack. This parameter change enables improved positioning accuracy through increased contact area without requiring complex mechanical adjustment mechanisms.

Function Achieved in This Case
The device enables easy and reliable positioning of banknotes within the container, reducing the need for additional pressure elements and minimizing wear, while allowing for efficient feeding and separation of banknotes, thereby optimizing storage and transport efficiency.
Implementation Method 1
A portion of the flexible area of the vane contacts the supplied single sheet already in its lower half and presses the single sheet at least in the contact area against the front side of the stack already contained in the container
