Money Handling Fallback Control for Maintenance-Covered Faults
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional money handling machines lack the ability to determine if they are covered by maintenance service, leading to inefficient and potentially harmful operator interventions during abnormal states, which can complicate restoration processes.
Innovation Solution
A valuable medium handling apparatus equipped with a maintenance information acquisition unit to determine maintenance service status and a notification unit to inform operators and external terminals about the need for professional intervention, along with a fallback processing unit to restrict operations and prevent worsening of abnormal states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operator performs restoration operation without knowing maintenance service status, then the operator can immediately act on abnormal states, but the operator may make incorrect operations that complicate the abnormal state and hinder restoration work
Solution Approach 1:
The system provides feedback to the operator about the maintenance service status through the notification unit. When maintenance service is active, the operator receives information that guides appropriate actions, preventing incorrect restoration operations while maintaining efficient response to abnormal states.
Solution Approach 2:
The notification unit acts as an intermediary between the maintenance service system and the operator. It conveys maintenance status information to the operator, enabling informed decision-making about whether to perform restoration operations or wait for professional maintenance personnel.
2Loss of time
If the operator performs restoration operation without maintenance service coverage information, then the operator can respond quickly to abnormal states, but the operator lacks guidance on appropriate restoration procedures
Solution Approach 1:
The system performs preliminary action by notifying the operator of the maintenance service status before the operator attempts restoration operations. This advance information allows the operator to prepare appropriate responses or wait for professional guidance, avoiding time-wasting incorrect operations.
Solution Approach 2:
The notification unit provides feedback about maintenance service coverage to the operator, enabling the operator to understand the appropriate level of intervention required and follow correct restoration procedures without wasting time on incorrect operations.
3Device complexity
If the system does not notify operator about maintenance service status, then the system remains simple to operate, but the operator cannot determine whether professional maintenance intervention is needed
Solution Approach 1:
The notification unit serves as a simple intermediary component that conveys maintenance service status information from the maintenance management system to the operator. This adds minimal system complexity while providing crucial information about whether professional intervention is needed.
Solution Approach 2:
The system performs self-service by automatically acquiring and notifying the operator of maintenance service status without requiring complex manual configuration. The maintenance information acquisition unit automatically retrieves status information, and the notification unit delivers it to the operator through simple notification mechanisms.

AI summary
An abnormal state of a valuable medium handling apparatus is efficiently eliminated. A money handling apparatus 1 holds data indicating whether or not it is covered by a maintenance service. The money handling apparatus 1 is communicably connected to a maintenance center server 80 disposed outside a branch. When an abnormal state such as jamming or miscalculation of money is detected (S1), the money handling apparatus 1 confirms whether or not it is covered by the maintenance service (S2). If the money handling apparatus 1 is covered by the maintenance service, it is notified to an operator (S3). The money handling apparatus 1 performs a fallback operation to restrict a function related to the abnormality (S4), and notifies the maintenance center server 80 of the abnormality (S5). The maintenance center server 80 dispatches a maintenance person to the branch of a financial institution to restore the apparatus 1.
