Money Processing Device Progress Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing money processing devices lack the ability to inform users when examination processing is complete, leading to inefficiencies due to uncertainty in completion time, causing users to wait unnecessarily.
Innovation Solution
A money processing device equipped with a control unit that calculates and notifies the remaining time or degree of progress of examination processing, allowing users to leave the device and predict working time, with options for display on an external device or storage for log analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If examination processing is performed without notifying remaining time or progress, then the device structure remains simple, but user working efficiency deteriorates due to inability to predict completion time
Solution Approach 1:
The control unit calculates and notifies the remaining time or degree of progress of examination processing to the display unit, creating a feedback loop that informs users of processing status. This resolves the contradiction by adding minimal computational functionality to improve user working efficiency without significantly increasing device complexity.
2Ease of operation
If no progress notification is provided during examination processing, then the device operates simply, but user convenience worsens as users cannot leave the device or predict working time
Solution Approach 1:
The control unit provides feedback by calculating and notifying the remaining time or degree of progress during examination processing. This allows users to conveniently leave the device and predict completion time, improving ease of operation with minimal added control functionality.
3Loss of information
If examination processing status is not displayed, then the device maintains simple operation, but information availability to users deteriorates
Solution Approach 1:
The control unit calculates and notifies the remaining time or degree of progress of examination processing to the display unit, providing essential processing status information to users. This resolves the contradiction by implementing a simple notification system that prevents information loss without significantly increasing device complexity.

AI summary
A money processing device includes a storage unit that stores money, a quantity measurement unit that measures a quantity of the money stored in the storage unit during examination processing, and a control unit that performs control of calculating a remaining time or a degree of progress of the examination processing and notifying the calculated remaining time or degree of progress of the examination processing.
