ATM Bill Cassette Connector Alignment for Compact Stacked Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bill storage units in automated teller machines have a complex structure due to separate power supply and communication signal transmission components for vertically stacked cassettes, leading to increased volume occupation and inconvenient cassette handling and mounting.
Innovation Solution
A simplified configuration using an external control board for power supply and communication signal transmission to both cassettes, with internal control boards and connectors for signal distribution, along with a position alignment mechanism to ensure accurate connector interconnection and a locking device for convenient handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power supply and communication signal transmission components are provided for each vertically stacked cassette, then reliable power supply and signal transmission to each cassette is ensured, but the device structure becomes complicated and occupies large volume
Solution Approach 1:
The patent merges separate power supply and communication signal transmission components into a single integrated control board that serves multiple cassettes. The external control board provides both power supply and communication signals to upper and lower cassettes simultaneously, eliminating the need for separate components for each function and reducing overall device complexity while maintaining reliability through unified control architecture.
Solution Approach 2:
The external control board is designed with multi-functionality to perform both power supply and communication signal transmission to multiple cassettes. This universal component replaces what would traditionally require separate dedicated components for each function, achieving space efficiency and structural simplification without compromising the reliability of individual cassette operations.
2Adaptability or versatility
If separate power supply and communication signal transmission components are provided for each vertically stacked cassette, then each cassette can be independently controlled, but the components occupy a large volume
Solution Approach 1:
The patent combines multiple control functions into a single external control board that serves both upper and lower cassettes. By integrating power supply circuits and communication signal transmission circuits into one unified component, the device achieves compact volume while maintaining the ability to independently control each cassette through separate signal pathways from the shared control board.
Solution Approach 2:
The control architecture implements a nested structure where the external control board contains integrated circuits for both power supply and communication signals, which in turn control multiple cassettes. This nested arrangement allows multiple functions to be housed within a compact volume, reducing the overall device size while preserving independent cassette control capabilities.
3Ease of operation
If the upper cassette and lower cassette are separated, then each cassette can be independently handled and mounted, but the structure becomes more complex with separate control components
Solution Approach 1:
The patent segments the physical cassettes (upper and lower) as separate, independently handleable units while using a unified external control board to manage both. This segmentation allows workers to easily remove, transport, and mount individual cassettes without dealing with complex integrated structures, while the control board maintains simplified connectivity through standardized interfaces for each cassette.
Solution Approach 2:
The external control board serves as a universal control unit that can interface with multiple separate cassettes through standardized connections. This multi-functional design allows the same control board to manage both upper and lower cassettes independently, simplifying the overall structure compared to having separate control components for each cassette while maintaining ease of handling and mounting.
4Reliability
If connectors are provided for power supply and communication signal transmission between cassettes, then electrical connection is achieved, but the connectors are vulnerable to damage during handling and mounting
Solution Approach 1:
The patent incorporates a position alignment mechanism that performs preliminary alignment of connectors before actual connection occurs. The alignment guides ensure that connectors are properly positioned and engaged in a controlled manner, preventing misalignment or forced connection that could damage the connectors during cassette handling and mounting operations, thereby protecting the electrical connection reliability.
Solution Approach 2:
The connector design includes protective features such as recessed mounting positions and alignment guides that cushion and protect the connectors from external forces during handling. The position alignment mechanism acts as a protective barrier, ensuring connectors engage smoothly without exposure to damaging impacts or misalignment stresses, thus reducing connector damage risk while maintaining reliable electrical connections.
