Single Drive Unit Coupling for Dual ATM Voucher Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
ATMs require separate drive units for each receiving area and withdrawal module, leading to high costs and space constraints.
Innovation Solution
A single drive unit is coupled to both withdrawal modules using a coupling unit with freewheels, allowing selective driving of either module by reversing the shaft's direction, reducing the need for multiple drive units and minimizing space and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate drive unit is provided for each receiving area and withdrawal module, then each withdrawal module can be driven independently and reliably, but the installation space increases and costs increase
Solution Approach 1:
The patent combines multiple drive functions into a single drive unit by using a common shaft that can rotate in different directions. The first and second withdrawal modules are both coupled to this single shaft, allowing one drive unit to control multiple modules instead of requiring separate drive units for each module.
Solution Approach 2:
The single drive unit is designed with multi-functionality to drive both the first and second withdrawal modules. The shaft can rotate in a first direction to drive the first module and in a second direction to drive the second module, making one drive unit serve multiple purposes and replacing what would traditionally require two separate drive units.
2Ease of operation
If a separate drive unit is provided for each receiving area and withdrawal module, then each module can be controlled independently, but the overall system cost increases
Solution Approach 1:
The patent merges multiple drive units into a single drive unit with a common shaft that controls both withdrawal modules. This reduces the total number of drive units from two to one, simplifying the system while maintaining independent control capability through directional rotation.
Solution Approach 2:
The single drive unit is designed to perform multiple functions by rotating the shaft in different directions. One rotation direction drives the first withdrawal module while the opposite direction drives the second module, allowing one universal drive unit to replace multiple specialized drive units.
3Area of stationary object
If two withdrawal modules are driven via a single drive unit with freewheels, then the installation space and costs are reduced, but the control mechanism becomes more complex
Solution Approach 1:
The patent introduces freewheels as intermediary elements between the single drive shaft and the two withdrawal modules. These freewheels act as mediators that allow the shaft to selectively drive different modules based on rotation direction, simplifying the coupling mechanism while maintaining space efficiency.
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
This design enables a compact, cost-effective solution by allowing a single drive unit to operate two withdrawal modules, simplifying control and reducing overall drive unit requirements.
Implementation Method 1
The coupling unit has a first and a second freewheel, which are mounted on the shaft in such a way that the first freewheel is coupled to the first trigger module and the second freewheel is coupled to the second trigger module. The output force of the shaft is thus transmitted to the first trigger module in the first direction of rotation of the shaft via the first freewheel
Implementation Method 2
the second freewheel is coupled to the second trigger module. The output force of the shaft is thus transmitted via the second freewheel and possibly other elements of the coupling unit to the second trigger module, which is thus driven
Implementation Method 3
The first freewheel is in particular non-rotatably connected to a first gear which is in engagement with a gear arrangement of the first trigger module. Thus, when the first freewheel rotates, the first gear wheel is also rotated, which in turn drives the gear wheel arrangement of the first trigger module.
Implementation Method 4
a second gear wheel is non-rotatably connected to the second freewheel, which gear wheel engages with a gear wheel arrangement of the second trigger module

AI summary
The device has a first flue module (26) to remove the value notes in a first receiving area from a first money box (18) and to supply the value notes to the first money box. A second flue module (28) removes the value notes in a second receiving area from a second money box (20) and to supply the value notes to the second money box. A drive unit (38) is provided, such that the first and second flue modules are coupled together by a coupling unit (42) to drive the flue modules by the drive unit.
