Bank Note Handling Machine UV Source for Manual Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bank note handling machines often fail to operate efficiently due to slow processing and erroneous decisions regarding authentic bank notes, especially when dealing with dirty or worn notes, leading to repeated manual input and delays in handling large quantities.
Innovation Solution
Incorporating a UV source that emits ultraviolet radiation externally, allowing users to manually authenticate bank notes, which reduces the need for repeated inputs and speeds up the handling process by enabling direct inspection of non-accepted notes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a note validation unit is used to automatically determine authenticity, then the handling speed is improved, but erroneous decisions occur on dirty or worn notes causing repeated manual input
Solution Approach 1:
The patent introduces a UV light source as an intermediary tool that enables users to independently verify authenticity of notes rejected by the automatic validation unit. This intermediary mechanism allows users to distinguish between genuinely counterfeit notes and authentic notes that were incorrectly rejected due to dirt or wear, thereby reducing repeated manual input while maintaining handling speed.
Solution Approach 2:
The patent empowers users to perform their own authenticity verification using the integrated UV light source, eliminating the need for repeated automatic validation attempts. Users can independently inspect rejected notes and make informed decisions about whether to re-insert them, reducing the burden on the automatic validation system and improving overall handling efficiency.
2Measurement precision
If multiple detectors with different determining principles are used, then the authenticity determination accuracy is improved, but the device complexity increases
Solution Approach 1:
Instead of adding more complex detectors to the automatic validation unit, the patent introduces a UV light source as a simple intermediary tool that users can operate manually. This approach achieves enhanced authenticity verification capability without increasing the complexity of the automatic detection system, as the UV light source works independently alongside the existing detectors.
Solution Approach 2:
The UV light source enables users to perform their own authenticity verification without relying on complex automatic detection systems. This self-service approach simplifies the overall device architecture by transferring some verification functionality from the complex automatic system to the user, who uses the simple UV light source for manual inspection.
3Device complexity
If a single output position is used for all notes, then the device complexity is reduced, but the handling time increases when notes must be manually removed
Solution Approach 1:
The UV light source acts as an intermediary tool that enables rapid verification of rejected notes at the single output position. Users can quickly inspect notes using the UV light source before deciding whether to re-insert them, minimizing the time delay caused by the single output position configuration without requiring additional output positions or complex routing mechanisms.
