Self-Service POS Timing Monitoring for Early Failure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sales processing apparatuses lack the capability to predictively diagnose defects during active use, leading to potential downtime and inefficiencies, as they primarily focus on detecting defective operations rather than predictive signs of failure.
Innovation Solution
A self-service POS terminal equipped with a processor that acquires and compares processing times for various operations, such as code symbol reading, banknote, and coin dispensing, against reference times to detect early signs of defective operations, allowing for proactive notification and maintenance without requiring the apparatus to be removed from service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated failure diagnosis operations are performed during non-active periods, then defective operations can be detected, but the machine requires downtime and predictive signs cannot be detected during active use
Solution Approach 1:
The system performs preliminary failure diagnosis actions during active operation by continuously monitoring operation times and comparing them against reference values. This allows predictive signs to be detected before actual failures occur, eliminating the need for separate non-active diagnosis periods and reducing downtime while maintaining reliability.
2Productivity
If the machine operates continuously without interruption, then productivity is maintained, but predictive failure diagnosis cannot be performed
Solution Approach 1:
The system maintains continuous operation while performing failure diagnosis by integrating the monitoring function into the active operation itself. The processor continuously acquires operation times and compares them against reference values during normal sales transaction processing, ensuring both productivity and predictive failure detection are maintained simultaneously without interruption.

AI summary
A sales processing apparatus includes a processor and an input and output unit configured to perform an operation for a sales transaction processing. The processor is configured to acquire the time required for the input and output unit to perform the operation for the sales transaction processing of a sales transaction, then determine whether the time required for the input and output unit to perform the operation during the sales transaction exceeds a reference time for the input and output unit to perform the operation. A notification is output if the time required for the input and output unit to perform the operation during the sales transaction exceeds the reference time.
