Tray Unit Assembly for Media Handling in ATMs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated teller machines require an efficient tray unit for conveying and separating media, as existing systems are not optimized for efficient media handling and stacking.
Innovation Solution
A tray unit assembly with a housing, a separating/stacking unit including roller units, a tray unit with a first and second tray body, and an elevating member that moves the second tray body between the roller units, along with a clamping plate and link driving unit for linear movement, enabling efficient media separation and stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a tray unit is used for conveying and separating media in deposit/withdrawal machines, then media handling capability is improved, but existing systems are not optimized for efficient media handling and stacking
Solution Approach 1:
The second tray body is designed to be vertically movable relative to the first tray body, allowing dynamic adjustment between different operational positions (receiving position, separating position, stacking position). This dynamic configuration enables the tray unit to adapt to different media handling tasks, improving productivity while maintaining a relatively simple overall structure.
Solution Approach 2:
The tray unit is divided into multiple functional components: first tray body for receiving media, second tray body for separation and stacking, elevating member for vertical movement, and clamping plate for securing media. This segmentation allows each component to perform its specific function efficiently, contributing to optimized media handling without excessive complexity.
2Productivity
If the second tray body is made vertically movable to connect to different roller units, then media separation and stacking efficiency is improved, but structural complexity increases
Solution Approach 1:
The elevating member acts as an intermediary mechanism between the first tray body and the second tray body, providing the vertical movement function. This dedicated intermediary component simplifies the overall structure by concentrating the movement function in a single element, rather than distributing complexity across multiple components.
Solution Approach 2:
The vertical movability is implemented only where needed - specifically in the second tray body's connection to the first tray body - while other parts of the system remain fixed and simple. This localized application of complexity achieves the required functionality without unnecessarily complicating the entire device.
3Stability of the object's composition
If the clamping plate is made vertically movable to press media, then media stacking stability is improved, but device complexity increases
Solution Approach 1:
The clamping plate is designed to be vertically movable under its own weight or controlled by a simple mechanism, allowing it to automatically press and secure media in the stacking position. This self-service approach provides stable media stacking without requiring a complex actuated clamping mechanism.

AI summary
A tray unit assembly includes a housing, a separating/stacking unit, a tray unit and an elevating member. The separating/stacking unit includes a separating roller unit and a stacking roller unit provided in the housing. The tray unit is provided to be inserted into the housing and includes a first tray body fixed to the housing when the tray unit is inserted into the housing, and a second tray body connected to the first tray body to be slidable in a vertical direction and having a media stacking space formed therein. The elevating member is disposed to be movable up and down and configured to be in contact with a bottom surface of the second tray body to move the second tray body toward the stacking roller unit or the separating roller unit.
