Money Handling System with Separate Recognition Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing money handling systems face challenges in reliably managing amount-of-money data for both stored changes in a money change machine and money transported via a pneumatic tube to another apparatus, often leading to errors and inefficiencies in tracking and processing.
Innovation Solution
A money handling system comprising a money change machine with recognition units, a pneumatic tube, and a separate recognition machine, where the control unit calculates and verifies the deposit amount by transmitting information between these components, ensuring accurate tracking and storage of banknotes or coins, and includes a notification system to prevent errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pneumatic tube is used to transport money between a cash register and a cash room, then the physical transport of money is automated and efficient, but the management and tracking of amount-of-money data becomes unreliable and error-prone
Solution Approach 1:
The system implements feedback by having the control unit receive recognition results from both the money change machine and the recognition machine, then calculate and verify the total deposit amount. This closed-loop feedback mechanism ensures data reliability by cross-checking information from multiple sources and providing notifications when discrepancies occur, directly resolving the unreliability of amount-of-money data management while maintaining pneumatic tube transport efficiency.
2Ease of operation
If money is separated into change (small denomination) and transport (large denomination) categories, then the money handling process becomes more organized, but the complexity of tracking and managing different categories increases
Solution Approach 1:
The control unit serves multiple functions: it receives data from the money change machine, receives recognition results from the recognition machine, calculates the total deposit amount, verifies data consistency, and sends notifications. This multi-functional approach consolidates what would otherwise be separate tracking systems into a single unified controller, reducing overall system complexity while maintaining organized handling of different money categories.
3Measurement precision
If a separate recognition machine is provided to recognize paper sheets for pneumatic tube transport, then the recognition accuracy is improved, but the system complexity and number of components increases
Solution Approach 1:
The system merges the functions of the money change machine and the recognition machine through a unified control unit that processes data from both sources. By integrating the control and data processing functions, the system achieves improved recognition accuracy through specialized hardware while avoiding the complexity of completely separate systems, as the control unit coordinates both machines and consolidates data management.

AI summary
A recognition machine 40, 90 connected to a pneumatic tube 14 is provided separately from a money change machine 20, 70. The recognition machine 40, 90 includes a recognition unit 46, 96 configured to recognize a paper sheet or a coin having been put thereinto, and a storing mechanism 48, 98 configured to store the paper sheet or the coin having been recognized by the recognition unit 46, 96, into a storing member for pneumatic tube 16 to be transported by a pneumatic tube 14. A control unit 60, 100 is configured to calculate a deposit amount of the paper sheet or the coin, by adding up information relating to the paper sheet or the coin stored in the money change machine 20, 70 and information relating to a paper-sheet recognition result or coin recognition result by the recognition unit 46, 96 of the recognition machine 40, 90.
