Solution Overview

Problem

Conventional banknote storing/feeding units with a tape single-wound type design are limited by the inability to take a large turning angle of the guide body between the drum and the reel, resulting in inefficient utilization of winding spaces and a reduced capacity for storing banknotes.

Innovation Solution

A banknote storing/feeding unit with a guide body that swings between the drum and the reel, positioned within a region parallel to the virtual line connecting their rotational centers, allowing for a larger turning angle and effective utilization of winding spaces, and featuring contact rollers to manage the banknotes and maintain the relationship between the outer wound diameter and swinging angle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the guide body is positioned with its supporting point near the inlet/outlet or outside the region parallel to the virtual line connecting drum and reel centers, then the structure is simpler and easier to manufacture, but the turning angle of the guide body is limited and the winding space utilization is poor

Engineering Contradiction:

Improveguide body positioningVSAvoidnumber of banknotes stored

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The guide body is designed to swing dynamically between the drum and reel, with its supporting point positioned within the region parallel to the virtual line connecting their centers. This dynamic positioning allows the guide body to adapt its angle according to the winding process, maximizing the turning angle and effectively utilizing the winding space between the drum and reel, thereby increasing the number of banknotes that can be stored.

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If the guide body takes a small turning angle between drum and reel, then the structure is more stable and easier to control, but the winding spaces of drum and reel are not effectively utilized

Engineering Contradiction:

Improveguide body stabilityVSAvoidstorage capacity

Core Design Contradiction:

Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

3Quantity of substance

If the supporting point of the guide body is positioned to allow large turning angle, then the winding space utilization is improved, but the guide body may become less stable during operation

Engineering Contradiction:

Improvenumber of banknotes storedVSAvoidguide body stability

Core Design Contradiction:

Quantity of substanceVSStability of the object's composition

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The supporting point of the guide body acts as an intermediary element positioned within the region parallel to the virtual line connecting the drum and reel centers. This strategic positioning allows the guide body to pivot smoothly through large angles while maintaining stability, as the supporting point serves as a stable fulcrum that enables the guide body to navigate the space between the drum and reel effectively.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Quantity of substance

If the guide body swings with larger amplitude to utilize winding space, then the storage capacity increases, but the control precision and reliability of banknote winding may decrease

Engineering Contradiction:

Improvestorage capacityVSAvoidwinding reliability

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms that monitor the winding process and adjust the guide body's swinging motion accordingly. This feedback control ensures that even with larger swinging amplitudes, the guide body maintains precise control over the banknote winding, preventing deviations and ensuring reliable operation throughout the storage process.

AI summary

An object of the invention is to provide a banknote storing/feeding unit (23) which is capable of effectively utilizing winding spaces of a drum (37) and a reel (38), to increase the number of banknotes to be stored. The banknote storing/feeding unit includes the drum which winds and rewinds a banknote together with a tape (36), and the reel which winds and rewinds the tape on and from the drum. A guide body (41) swinging according to winding and rewinding of the tape and the banknote on and from the drum is provided between the drum and the reel. The guide body has a guide passage (43) that guides the tape and the banknote to be wound and rewound on the drum. The guide body swings centering on a supporting point (41a) located within a region (A) parallel to a virtual line (L1) connecting a rotational center (47) of the drum and a rotational center (49) of the reel.
