ATM Picker Mechanism for Mixed Financial Instrument Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated banking machines lack enhanced capabilities for handling financial instrument sheets, security, and user-friendly operation, particularly in efficiently processing and storing mixed types of financial instruments like currency notes and checks.
Innovation Solution
An automated teller machine (ATM) design with a user interface that includes a card reader, cash acceptor mechanism, and picker mechanism to separate and process financial instrument sheets, along with enhanced security features like a secure chest for storage and multicolor light emitting devices for user guidance, and convex mirrors for observing surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a picker mechanism is added to separate financial instrument sheets, then the capability to handle mixed types of financial instruments is improved, but the device complexity increases
Solution Approach 1:
The picker mechanism divides the stack of financial instruments into individual sheets or groups, separating them for individual processing. This segmentation enables the system to handle mixed types of instruments (currency notes, checks, etc.) by processing each item individually through the validation and selection mechanisms, thereby improving versatility while managing complexity through modular design
2Reliability
If a secure chest with restricted access is provided, then security is improved, but the ease of servicing the machine deteriorates
Solution Approach 1:
The secure chest is divided into multiple compartments with different access levels. The main secure storage area requires restricted access for high-value items, while servicing areas and lower-value storage sections are more accessible to technicians. This segmentation allows maintenance personnel to service the machine without compromising the security of the main vault, resolving the contradiction between security and ease of servicing
Solution Approach 2:
A service door or access mechanism acts as an intermediary between the external servicing environment and the internal secure chest. This intermediary structure allows technicians to access specific servicing areas for maintenance and repair while maintaining security restrictions for the primary storage compartments, thus preserving both security and ease of servicing
3Ease of repair
If cash acceptor mechanism is made movable for servicing, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The cash acceptor mechanism is designed with movable components that can be repositioned between operational and servicing states. This dynamic design allows the mechanism to be easily accessed for maintenance while in use, improving ease of repair. The movability is achieved through tracked or slide-based mechanisms that provide smooth transitions between positions, managing the added complexity through well-defined motion paths and integration with the existing structural framework

AI summary
A card activated automated banking machine (10) includes a user interface (15). The user interface includes a card reader (16), receipt printer opening (30), cash dispensing opening (38) and deposit accepting opening (40). A stack of notes (84) input to the machine are separated one by one from the stack through the action of at least one picking member (158, 352) and at least one stripper member (64, 162, 354). Note holding cassettes include sensors operative to detect near full and near empty conditions. At least one processor in the machine is operative to control the addition and/or removal of notes from each cassette so as to avoid overfilling or depleting the cassettes which may result in machine malfunctions.
