Cash Dispensing Safe with Sensor-Based Currency Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cash dispensing systems are costly, inefficient, and lack accurate accounting of money within, leading to security issues and high service requirements, as they often require manual counting and have limited flexibility to adapt to varying coin and bill needs.
Innovation Solution
A cash dispensing safe with integrated sensors and RFID systems that track and dispense rolled coins and stacked bills, providing a closed-loop accounting system, flexible configuration, and secure, automated tracking of currency value and quantity, minimizing human error and optimizing inventory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual counting and tracking of money is used, then the system is simpler and cheaper, but accuracy and security are compromised due to human error
Solution Approach 1:
The patent replaces manual mechanical counting with automated sensor-based detection systems. Optical sensors, RFID readers, and weight sensors automatically detect and track currency items, eliminating human error while maintaining reasonable system complexity through modular sensor integration.
Solution Approach 2:
The system performs self-counting and self-tracking of money through integrated sensors that automatically detect currency presence, denomination, and quantity without requiring external manual verification, enabling the system to monitor its own state continuously.
2Quantity of substance
If a large secure box is used to hold all tube columns, then all coins and bills can be stored, but the product becomes very large and heavy
Solution Approach 1:
The patent divides the storage system into multiple separate tube columns that can be individually positioned and secured. Each column acts as an independent storage unit, allowing the overall system to maintain high capacity while distributing weight and enabling a more compact footprint compared to a single large box.
3Adaptability or versatility
If the front face of the secure box is made large enough to hold all tube columns, then all money can be dispensed, but the product size increases significantly
Solution Approach 1:
The patent arranges tube columns in a multi-dimensional configuration within the safe, utilizing vertical and depth dimensions rather than only horizontal front-face space. This allows all columns to be accessible through a smaller front opening by implementing multi-level dispensing mechanisms and rear-access configurations.
4Reliability
If no tracking system is used, then the system is simpler, but there is no verification of tubes being dispensed leading to security issues
Solution Approach 1:
The patent implements sensor feedback systems that continuously monitor tube column status, detect when tubes are dispensed, and verify dispensing accuracy. The sensors provide real-time feedback to the control system, enabling automatic verification and alerting mechanisms that enhance security without requiring complex manual tracking procedures.

AI summary
A readily reconfigureable cash dispensing system for providing change, such as coins of different values and bills or currency of different denominations needed by a retail store, grocery store, busy convenience store, or the like. A tray or trays for storing and delivering multiple rolls of coins or bills of a first value, as well as, a tray or trays for storing and delivering stacks of bills are described herein. A bill acceptor may be employed to accept bills used to purchase rolls of coins and stacks of bills, and a system controller can sense restocking and dispensing events to maintain an accurate inventory of cash in the bill acceptor, as well as, the total cash stored in the form of coin rolls or rolls bills, as well as, bill stacks.
