Stacked Bill Storage Box with Aligned Access Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bill storage boxes in ATMs face difficulties in removing jammed bills due to the orientation and opening degree of doors, which complicates the removal process and affects user satisfaction.
Innovation Solution
The solution involves stacking at least two bill storage units with a common door for loading and unloading bills, where the opening and closing directions of the door for the first storage unit and the internal conveyance path are aligned, facilitating easier access and removal of jammed bills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple bill storage boxes are disposed side by side in the anteroposterior direction, then the number of denominations that can be handled increases, but the device grows in size in the anteroposterior direction
Solution Approach 1:
The patent transitions from arranging bill storage boxes in the anteroposterior direction (horizontal arrangement) to stacking them in the vertical direction (vertical arrangement). This dimensional change allows multiple storage boxes to be accommodated within the same horizontal footprint, thereby increasing the number of handleable denominations without expanding the device's anteroposterior size.
2Ease of operation
If a door is provided in the bill storage box for removing jammed bills, then jammed bills can be removed, but the removal process becomes complicated depending on the opening and closing direction and degree of the door
Solution Approach 1:
The patent divides the bill storage box into multiple independent storage units (first bill storage unit, second bill storage unit, etc.), each with its own door. This segmentation allows each storage unit to be accessed independently, simplifying the removal of jammed bills from specific units without requiring complex coordination between multiple doors or storage units.
Solution Approach 2:
Instead of requiring the door to open in a specific direction or requiring complex multi-step opening/closing operations, the patent designs the door to open in a straightforward manner that facilitates direct access to the interior of the storage unit. The door opening mechanism is simplified to allow users to easily reach inside and remove jammed bills without complicated procedures.
3Volume of moving object
If plural storage units are stacked, then the device maintains compact size, but jammed bills in the internal conveyance path become harder to access for removal
Solution Approach 1:
By segmenting the storage system into multiple independently accessible storage units with separate doors, the patent ensures that jammed bills in any specific storage unit can be accessed by opening only that unit's door, rather than requiring access to the entire stacked structure. This maintains compact overall volume while preserving ease of access to individual storage units for bill removal.

AI summary
The present invention is characterized in that at least a first bill storage unit and a second bill storage unit are stacked and arranged in the stated sequence from a bill insert/discharge port side provided to the upper surface of the bill storage box; a door for loading and removing bills inside the bill storage units, and an opening and closing part for removing bills retained in an internal conveyance path between the first bill storage unit and the internal conveyance path are included; and the opening and closing direction of the door for loading and removing bills in the first bill storage unit and the opening and closing direction of the opening and closing part are substantially the same.
