Money Handling Machine Outlet Detection and Process Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated trading machines face challenges in accurately determining whether money has been removed from the receiving part, leading to difficulties in managing and processing the remaining funds due to issues like differences in transport direction and failure in money transport.
Innovation Solution
A money handling machine equipped with a detector to identify removal actions and a controller that switches processes based on detection results, allowing for appropriate processing of funds remaining in the withdrawal unit by transporting them to either storage or a holder depending on detection and recognition outcomes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If money is transported through the receiving part without detection of removal actions, then the processing speed is maintained, but the accuracy of determining whether money has been removed deteriorates
Solution Approach 1:
A detector is introduced as an intermediary component between the receiving part and the controller. The detector monitors removal actions by detecting changes in the receiving part (such as weight changes or positional changes), providing information to the controller without requiring direct complex interaction between the controller and the money itself. This intermediary detection mechanism improves measurement precision while keeping the overall system complexity manageable.
Solution Approach 2:
The system implements a feedback mechanism where the detector continuously monitors the receiving part and provides real-time information to the controller. When a removal action is detected, the controller receives this feedback and adjusts its processing accordingly, such as pausing operations or alerting operators. This feedback loop ensures accurate determination of money removal while maintaining efficient automated processing.
2Reliability
If the controller switches processes based on detector results, then the appropriateness of money processing is improved, but the response time deteriorates
Solution Approach 1:
The system prepares multiple processing paths in advance based on potential detector outcomes. The controller is pre-programmed with different processing routines for various detection scenarios (e.g., money removed, money not removed, partial removal). When the detector triggers a condition, the controller can immediately switch to the pre-prepared corresponding process, minimizing decision-making time and ensuring reliable appropriate processing without significant response time delays.
3Measurement precision
If money transport direction is changed to improve recognition, then the completeness of money recognition is improved, but the transport reliability deteriorates
Solution Approach 1:
The money transport system is designed to be dynamic, allowing the transport direction to be adjusted based on recognition needs. The transport mechanism can reverse direction or change orientation to present money from different angles to detectors or recognition systems. This dynamic adaptability ensures complete money recognition by examining money from multiple directions while maintaining transport reliability through controlled, reversible motion sequences that prevent money loss or damage.

AI summary
A storage stores money. An outlet can receive money delivered from the storage therein. The outlet is configured to allow the money to be removed from the inside of the outlet. A detector detects a removal action associated with removal of money from the outlet. The controller switches a process on money remaining in the outlet based on a detection result of the detector.
