Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated teller machines face complexity in separating and transferring bundled media, particularly when deposited horizontally, leading to issues like twisting of individual sheets.
Innovation Solution
An automated teller machine design featuring a deposit and withdrawal unit with a push plate, first and second pick-up rollers, and lifting and lowering drive units to manage the rollers, along with detection sensors, ensuring controlled separation and transfer of bundled media into individual sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bundled media are separated through feed rollers and gate rollers in a deposit and withdrawal unit, then media transfer is achieved, but twisting of individual sheets occurs
Solution Approach 1:
The patent divides the media separation process into distinct stages using separate functional components: a first pick-up roller for initial media pickup, a second pick-up roller for sequential media pickup, and a gate roller for final media transfer. This segmentation allows each component to perform its specific function optimally without causing twisting, as each roller contacts the media at different positions and times.
Solution Approach 2:
The first pick-up roller performs preliminary action by contacting the leading end of the bundled media first and beginning the separation process before the gate roller contacts the media. This preliminary pickup action ensures the media is properly positioned and controlled before the final transfer, preventing twisting during the overall process.
2Area of stationary object
If horizontal deposit configuration is used, then deposit space is optimized, but separation configuration becomes complex
Solution Approach 1:
The patent merges the functions of multiple rollers into a coordinated system where the first pick-up roller, second pick-up roller, and gate roller work together as an integrated unit. By combining these components in a horizontal arrangement, the system achieves both compact space utilization and simplified separation logic, as the rollers are positioned sequentially along the horizontal path rather than requiring complex vertical or multi-dimensional arrangements.
3Manufacturing precision
If multiple rollers are used for media separation, then separation precision is improved, but device complexity increases
Solution Approach 1:
The patent employs dynamic control of the rollers through a lifting and lowering mechanism that allows the first pick-up roller and second pick-up roller to move vertically relative to the gate roller. This dynamic adjustment enables precise timing and positioning of each roller during the media separation process, achieving high separation precision while managing complexity through automated control rather than fixed complex mechanical linkages.

AI summary
An automated teller machine includes: a deposit and withdrawal unit configured to allow deposit and withdrawal of a medium, which allows a bundle of media including multiple stacked media to be deposited; a discrimination unit that discriminates the medium; a storage unit in which the medium is stored; a conveyance path that transfers the medium between the deposit and withdrawal unit, the discrimination unit, and the storage unit. The deposit and withdrawal unit includes: a push plate unit on which the bundle of media is placed; a first pick-up roller for transferring the bundle of media in a deposit direction toward the discrimination unit when the bundle of media is placed on the push plate unit; and a second pick-up roller, disposed to be spaced apart from the first pick-up roller in the deposit direction, for transferring the medium from the bundle of media in the deposit direction.
