Banknote Insertion Scanner for Tamper-Proof Container Certification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for filling removable containers with banknotes lack reliable documentation and certification of contents before the containers are removed, leading to potential detection errors and tampering issues, which can result in discrepancies and fraud.
Innovation Solution
Incorporating a scanner, such as a Contact Image Sensor (CIS), downstream of the exchange element in the loading path to detect and store images of banknotes entering the container, allowing for a visual archive and certification of the exact content, including number, value, and characteristics, at the time of closure and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple ON/OFF optical sensors are used to detect banknotes, then the device complexity is reduced, but the measurement precision deteriorates due to detection errors
Solution Approach 1:
The patent applies the copying principle by creating a visual archive (copy) of banknotes through imaging technology. Instead of relying solely on simple optical sensors that may make errors, the system captures images of each banknote and stores them in a database. This visual copy serves as proof of the actual banknotes present, allowing for accurate verification and reconciliation even when sensor detection errors occur.
2Device complexity
If no documentation system is implemented for container contents, then the device complexity is reduced, but the reliability deteriorates due to undetectable tampering
Solution Approach 1:
The patent implements feedback by creating a closed-loop verification system. The imaging system captures banknote images, which are then compared against the container closure documentation. When the container is opened or verified, the system checks whether the actual banknotes match the documented images. This feedback mechanism ensures reliability by detecting any tampering or discrepancies between the documented contents and actual contents.
3Measurement precision
If visual archiving of banknotes is implemented, then the measurement precision is improved through accurate documentation, but the device complexity increases due to additional imaging and storage systems
Solution Approach 1:
The patent applies preliminary action by capturing images of banknotes and documenting container contents before the container is sealed and removed from the system. The imaging system records the banknotes in advance, creating a visual archive that is stored and protected. This preliminary documentation ensures that accurate records exist before any potential tampering can occur, allowing for verification without requiring complex real-time monitoring systems.

Function Achieved in This Case
Ensures accurate documentation and certification of the banknote contents within the container, preventing errors and tampering by creating a visual record of each banknote, thereby enhancing trust and security in the transaction process.

AI summary
A device for the insertion of banknotes into containers in machines suitable for receiving and handling banknotes, comprises a container (18, 18', 18") for the banknotes (11), adapted to be closed and removed from the machine once filled, and a loading path (17), diverting from a circulation path (14) inside the machine and ending at said container (18, 18', 18"), for the insertion of banknotes (11) into the container. The device further comprises at least one scanner (24), placed along the loading path (17), for the optical detection of images of the banknotes entering into the container (18, 18', 18") and a memory (26) connected to the scanner (24) for storing the images detected thereby.
