ATM Bill Storage Unit Angled Withdrawal Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-type ATMs installed in kiosks along roadsides face challenges in performing maintenance, particularly replacing the bill storage unit, due to narrow working spaces, which can lead to collisions with vehicles and hinder easy access for maintenance personnel.
Innovation Solution
The ATM design includes a safety door with a locking function, a bill storage unit with a base that can be withdrawn at a predetermined angle and rotated for easy access, utilizing first and second guides to prevent interference with the kiosk structure, allowing for safe and efficient cassette replacement without protruding into the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bill storage unit is released only in a direction perpendicular to the front wall of the kiosk, then the safety door can be fully opened, but the curved wall must protrude beyond the front wall causing collision risk with traveling cars
Solution Approach 1:
The patent changes the withdrawal direction of the bill storage unit from a single direction (perpendicular to front wall) to a two-stage path: first at an angle (e.g., 45 degrees) relative to the front wall, then rotated to face the clerk. This dimensional change in movement path allows the bill storage unit to be accessed without the curved wall needing to protrude beyond the front wall, eliminating the collision hazard while maintaining maintenance accessibility
2Ease of repair
If the safety door is fully opened to enable bill storage unit replacement, then maintenance work can be performed, but the curved wall protrudes beyond the front wall creating safety hazards
Solution Approach 1:
The patent introduces a dynamic, two-stage withdrawal mechanism for the bill storage unit. Instead of a static, single-direction release, the system dynamically adjusts the withdrawal path: initially moving the bill storage unit out at an angled direction, then rotating it to face the clerk. This dynamic approach enables full maintenance access while keeping the kiosk's external profile within safety boundaries
3Object-affected harmful factors
If the kiosk is designed with narrow fore and aft space to minimize road obstruction, then vehicle safety is improved, but maintenance personnel cannot easily access the bill storage unit
Solution Approach 1:
The patent resolves the space constraint by changing the maintenance access path from a direct front-to-back movement to an angled withdrawal followed by rotation. This allows the bill storage unit to be accessed within the narrow kiosk footprint without requiring excessive fore and aft space, maintaining both road safety and maintenance accessibility

AI summary
The present invention provides a financial automated-teller machine comprising a main body having an operation unit and a cash deposit/withdrawal unit installed at a front face thereof; a safety door having a locking function and hingedly connected to an edge of the front face of the main body; a safe that is disposed within the main body and is opened and closed by means of the safety door; a bill storage unit with a bill-receiving and dispensing function for allowing a deposited bill to be received therein and a bill to be withdrawn to be dispensed therefrom; and a base that has the bill storage unit mounted thereon, is placed within the safe when the safety door is closed, can be withdrawn to the outside of the safe when the safety door is opened, and is provided with a first guide at a lower portion thereof so that the base can be withdrawn along the first guide. Thus, a maintenance work, particularly, a replacement work for the bill storage unit can be easily performed in an inner working space of a kiosk which is narrow in a fore and aft direction, and the maintenance work does not cause inconvenience to travelling cars or walkers. The present invention further provides a method of withdrawing a cassette provided in the automated-teller machine.
