Sheet Storing Device Guide Parts Prevent Banknote Catching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sheet storing devices, banknotes can get caught between a support element and the inner surface of the storage bag, leading to bending or remaining at the step.
Innovation Solution
The sheet storing device incorporates a first guide part with a flat surface that contacts the inner surface of the storage bag and a second guide part with a flat surface that contacts the outer surface of the storage bag, ensuring no step at the guide surface to prevent banknotes from getting caught.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a support element is used to hold banknotes before storing, then the banknotes can be supported and moved, but the banknotes may get caught between the support element and the inner surface of the storage bag, leading to bending or remaining at the step
Solution Approach 1:
The support element is divided into multiple guide parts (first guide part and second guide part) with flat surfaces that create a segmented guide structure. This segmentation allows the banknotes to follow a defined path through multiple contact points, preventing them from getting caught between a single support element and the storage bag inner surface.
Solution Approach 2:
The flat surfaces of the guide parts act as intermediary elements between the support element and the banknotes. These flat surfaces provide a smooth transition path that mediates the contact between the banknotes and the storage bag, eliminating the harmful step formation that occurs with traditional single-element supports.
2Device complexity
If a simple support element is used, then the device structure is simple, but the banknotes may get caught at steps formed by the support element
Solution Approach 1:
The support element is segmented into multiple guide parts with flat surfaces arranged in sequence. This segmentation creates a stepped structure that is intentionally designed to guide banknotes smoothly from one level to another, preventing unintended step formation while maintaining structural simplicity through the use of basic geometric shapes.
Solution Approach 2:
Only specific portions of the guide parts are designed with flat surfaces that contact the banknotes, while other portions can have different geometries. This local quality approach ensures that the critical contact areas have the necessary smooth flat surfaces to prevent banknote catching, while the overall structure remains simple and easy to manufacture.

AI summary
A sheet storing device of the present disclosure includes: an attaching part configured to attach a storage bag for a sheet; a moving part configured to move the sheet toward inside of the storage bag; a first guide part configured to make contact with an inner surface of the storage bag; and a second guide part configured to make contact with an outer surface of the storage bag, and sandwich the storage bag together with the first guide part. The first guide part comprises a first flat surface configured to make contact with the sheet moved by the moving part. The second guide part comprises a second flat surface configured to make contact with the outer surface of the storage bag such that the sheet moved by the moving part makes contact with a part of the inner surface of the storage bag. The first guide part and the second guide part are disposed such that the first flat surface and the second flat surface are located on the same plane.
