Ticket Burster Cleaning Pad Drawer for Barcode Scan Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dust and other contaminants accumulate in lottery ticket vending machines, obstructing barcode readers and impeding the scanning ability of lottery tickets.
Innovation Solution
Incorporation of cleaning pad drawers that hold cleaning pads to remove dust and contaminants from ticket bursters by moving the cleaning pads through the ticket movement paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cleaning operations are performed regularly, then scan region cleanliness is improved, but machine downtime increases
Solution Approach 1:
The system performs cleaning operations before contamination accumulates to problematic levels. The controller monitors scan region conditions and schedules cleaning proactively rather than reactively, preventing barcode reading failures while minimizing interruptions to normal operation.
Solution Approach 2:
The ticket burster cleans itself using an integrated cleaning pad mechanism. The system automatically feeds cleaning pads through the scan region without requiring external intervention or manual cleaning operations, reducing downtime and maintaining continuous functionality.
2Reliability
If cleaning pads are manually replaced, then cleaning effectiveness is maintained, but operational complexity increases
Solution Approach 1:
The cleaning pad system operates automatically without manual replacement. The controller manages the cleaning pad supply, feeding new pads through the scan region as needed and eliminating the requirement for user intervention in maintenance operations.
Solution Approach 2:
The system uses disposable cleaning pads that are automatically replaced through the mechanism rather than manually handled. This approach simplifies maintenance by treating cleaning pads as consumable components that self-replace, reducing operational complexity while maintaining cleaning effectiveness.
