Money Processing Error Handling via Mobile Consent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing money processing systems face challenges in quickly and effectively handling errors, especially when operated by unfamiliar customers, as they lack efficient communication and guidance mechanisms for error correction.
Innovation Solution
A money processing system comprising a banknote processing apparatus, a server, and mobile terminals that transmit state information and consent information to facilitate error handling, allowing authorized bank clerks to quickly address errors through a communication network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If error information is transmitted to mobile terminals, then error handling speed is improved, but system complexity increases
Solution Approach 1:
The server performs multiple functions: it receives state information from the money processing machine, determines error occurrences, selects appropriate mobile terminals, and transmits consent information. This multi-functional approach consolidates complexity into a centralized server rather than distributing it across multiple components, resolving the contradiction by improving error handling speed through centralized coordination while managing system complexity through functional integration.
Solution Approach 2:
The server acts as an intermediary between the money processing machine and mobile terminals. It receives state information from the machine, processes error determination, and communicates with selected mobile terminals to obtain consent information. This intermediary role streamlines the error handling process by centralizing coordination logic, thereby reducing error handling time while containing system complexity within the server's modular architecture.
2Reliability
If consent information is obtained from multiple terminals, then error handling reliability is improved, but communication overhead increases
Solution Approach 1:
The server selects a predetermined number of mobile terminals to receive consent information, rather than notifying all possible terminals. This partial action approach ensures sufficient redundancy for reliable error handling while minimizing unnecessary communication overhead. The server transmits consent information to multiple terminals but stops at a predetermined number, balancing reliability requirements with communication efficiency.
Solution Approach 2:
The server pre-selects mobile terminals based on predetermined criteria before transmitting consent information. This preliminary selection process ensures that the right terminals are notified without requiring exhaustive communication with all possible terminals. By pre-determining which terminals should receive consent information, the system achieves reliable error handling while reducing communication overhead through targeted notifications.

AI summary
A money processing system includes: a money processing machine including a processing machine communication section and a processing machine controller; a first terminal including a first reception section, a first communication section, and a first controller; and a second terminal including a second reception section, a second communication section, and a second controller. The first terminal is a mobile communication terminal. The processing machine communication section transmits state information indicating a state of the money processing machine. In a case where the first reception section receives a consent operation to handle an error in the money processing machine, the first communication section transmits consent information. The error in the money processing machine is indicated by the state information. The second controller causes the second communication section to receive the consent information.
