Banknote Storing Device Non-Overlapping Drums
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote storing devices have limited capacity due to the fixed casing length and overlapping components, restricting the maximum number of banknotes that can be stored and fed efficiently.
Innovation Solution
A banknote storing device with multiple mechanisms arranged side by side, featuring rotating members and belt-shaped winding members, where the rotating members do not overlap with winding member accommodating units, allowing for increased storage capacity without compromising the casing's dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the casing length in the up-down direction is fixed and reels overlap with drums, then the device complexity is reduced, but the maximum storable banknote number becomes small
Solution Approach 1:
The patent transitions from a two-dimensional overlapping arrangement (in the up-down direction) to a three-dimensional non-overlapping arrangement by positioning reels and drums at different depths along the depth direction of the casing. This dimensional change allows both components to coexist without interference, increasing the outer diameter of the drum and thereby the maximum storable banknote number, while maintaining manageable device complexity through systematic spatial organization.
2Quantity of substance
If the diameter of the outer peripheral edge of the outermost tape is kept small, then the device fits within fixed casing dimensions, but the maximum storable banknote number is limited
Solution Approach 1:
The patent utilizes the depth direction as an additional spatial dimension to resolve the conflict between drum diameter and casing length. By positioning the reel further inside in the depth direction than the drum, the design allows the drum's outer peripheral edge to extend closer to the casing's front surface, maximizing the usable diameter for winding banknotes without increasing the overall casing depth beyond acceptable limits.
3Quantity of substance
If multiple banknote storing mechanisms are arranged side by side, then the storage capacity increases, but the device complexity and space requirements increase
Solution Approach 1:
The patent arranges multiple banknote storing mechanisms side by side along the depth direction of the casing, utilizing the third dimension (depth) rather than expanding the footprint area in the horizontal plane. This vertical stacking approach along the depth axis increases storage capacity while maintaining a compact footprint, effectively resolving the contradiction between storage capacity and device area.

AI summary
A banknote storing device (for example, a storing and feeding unit (20)), includes a plurality of banknote storing mechanism (24, 26) arranged inside a casing (20a) side by side along a depth direction of the casing (20a). When viewed in a predetermined direction that is a direction orthogonal to the depth direction of the casing (20a) and also orthogonal to an axis direction of rotating members (for example, drums (24a, 26a)), at least one of the rotating members is arranged at a position at which the rotating member does not overlap with any of winding member accommodating units (for example, reels (25a, 25b, 27a, 27b)).
