Coin Module Cassette Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coin supply systems for cash stations are inefficient and insecure, as they require manual handling and complex mechanical locking systems, leading to high operational costs and risks of coin loss or theft during replenishment.
Innovation Solution
A device with a supply cassette that uses guide means to securely attach to the coin module, featuring a locking mechanism that can be electronically controlled, ensuring the cassette remains locked during replenishment and preventing unauthorized access, while allowing for automated and secure coin transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locked supply cassette is used to transport coins to the coin module, then security against theft is improved, but the complexity of the locking system increases
Solution Approach 1:
The patent replaces complex mechanical locking systems with an electronic control unit that manages the locking mechanism. The control unit receives signals from the coin module and automatically controls the locking and unlocking of the supply cassette, eliminating the need for manual mechanical operations while maintaining security.
Solution Approach 2:
The system enables automatic replenishment where the control unit autonomously manages the entire process: detecting coin levels, unlocking the supply cassette, transferring coins to the coin module, and relocking the cassette. This self-service mechanism eliminates manual intervention, reducing both complexity and security risks.
2Productivity
If employees manually insert coins from the supply cassette into the coin input, then the replenishment process can be completed, but time expenditure and risk of coin loss increase
Solution Approach 1:
The supply cassette is pre-filled with coins at a central location before being locked and transported to the coin module. This preliminary preparation eliminates the need for manual coin handling at the checkout station, as the pre-filled cassette can be directly integrated and automatically emptied into the coin module.
Solution Approach 2:
The manual mechanical process of employees inserting coins is replaced by an automated system where the control unit manages the transfer of coins from the supply cassette to the coin module through an integrated mechanism, dramatically reducing operational time and eliminating human error.
3Ease of operation
If the supply cassette is opened for refilling, then coins can be inserted, but security risks and potential theft increase
Solution Approach 1:
The control unit acts as an intermediary between the refilling process and the locking mechanism. It manages the brief period when the cassette must be opened for refilling by coordinating with security systems and automatically relocking immediately after refilling, minimizing exposure time and maintaining security protocols throughout the process.
4Reliability
If not all coins are transferred from the supply cassette, then coins may be lost or stolen, but the replenishment process becomes incomplete
Solution Approach 1:
The control unit incorporates feedback mechanisms that monitor the coin transfer process from the supply cassette to the coin module. It detects when the transfer is complete and when coins remain in the cassette, automatically managing the process to ensure all coins are transferred and preventing loss or theft by maintaining secure containment throughout.

AI summary
The device has a storage for different coins, and a coin input chamber (4) for inputting the coins. An electronic control unit (2) detects coin money balances, and an interface is provided for connection with an accounting calculating unit. A locking device is arranged in an area of the coin input chamber such that a provision cash box (10) with coins is set on the coin input chamber. A rotatable flap (15) floats the coins of the cash box at a coin module (1). The rotatable flap is activated when the cash box is provided to the coin module in a locking condition. An independent claim is also included for a method for providing a cash station with coins.
