UV Coin Counter Attachment for Point-of-Sale Pathogen Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The spread of bacterial and viral pathogens on coins poses a challenge during contactless payment transactions, especially in the context of COVID-19, as existing systems lack effective sterilization at the point of sale.
Innovation Solution
An ultraviolet light attachment integrated into a coin counter to sanitize coins as they are sorted, ensuring pathogen elimination through UV exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mass sterilization of paper currency occurs at distribution and redistribution stages, then pathogen reduction is achieved, but sterilization is not available at the point of sale
Solution Approach 1:
The UV light attachment performs sterilization action in advance at the point of sale before the transaction completes, eliminating pathogens during the coin sorting process itself rather than relying on prior sterilization at distribution stages
Solution Approach 2:
The UV light attachment acts as an intermediary sterilization mechanism between the coin insertion and the transaction completion, providing the necessary pathogen reduction at the critical point of sale without requiring contactless card payments
2Reliability
If ultraviolet light attachment is integrated into coin counter, then pathogen elimination at point of sale is achieved, but device complexity increases
Solution Approach 1:
The UV light attachment is merged with the existing coin counter housing and integrated into the coin sorting mechanism, combining the sterilization function with the existing counting and sorting operations rather than adding a separate standalone system
Solution Approach 2:
The UV light attachment serves multiple functions: it sterilizes coins during the sorting process, acts as a protective barrier, and integrates with the existing coin counter mechanics, making the system multi-functional without requiring entirely separate components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively reduces bacterial and viral pathogens on coins, enabling safe contactless payment transactions by eliminating pathogens at the point of sale.
Implementation Method 1
The ultraviolet light spectrum has been scientifically proven to significantly reduce bacteria and viral pathogens. Coins are inserted through a coin-sorting slot on the top of the device and pass through an ultraviolet light during the sorting process.
