Terminal Management System for Mobile Purchase Error Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In self-service store systems, customers using mobile terminals may inadvertently exit the store without completing their payment, leading to errors in transaction processing, necessitating a mechanism to restrict purchase services on such terminals.
Innovation Solution
A terminal management system comprising an acquisition unit, detection unit, and restriction unit that acquires status information from mobile terminals, detects error conditions, and restricts purchase processing based on the number of detected errors, ensuring users complete transactions before exiting the store.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If self-service mobile terminal purchase processing is allowed without restrictions, then ease of operation and customer convenience are improved, but transaction reliability and completeness deteriorate due to incomplete payments
Solution Approach 1:
The system performs preliminary detection of error conditions and incomplete transactions before allowing the customer to exit the store. The management device monitors transaction status in real-time and identifies potential errors before they result in lost revenue, enabling preventive action rather than reactive correction.
Solution Approach 2:
The system implements continuous feedback by monitoring transaction status, detecting error conditions, and providing real-time information to both the mobile terminal and store management. This feedback loop enables the system to identify incomplete transactions and trigger appropriate responses such as notifications or restrictions.
2Reliability
If error detection and restriction mechanisms are implemented, then transaction reliability is improved, but device complexity and system overhead increase
Solution Approach 1:
The patent introduces a terminal management device as an intermediary between the mobile terminal and the purchase processing system. This intermediary handles the complex tasks of error detection, status monitoring, and restriction enforcement, thereby isolating the complexity from both the customer-facing mobile terminal and the core purchase processing system.
Solution Approach 2:
The mobile terminal autonomously checks its own transaction status and receives real-time feedback about error conditions. The terminal can independently determine whether it is restricted from completing purchases based on detected errors, reducing the need for complex centralized control and simplifying the overall system architecture.
3Reliability
If real-time monitoring of all terminals is performed, then transaction integrity is improved, but use of energy and computational resources increases
Solution Approach 1:
The system applies monitoring and detection resources selectively rather than uniformly to all terminals. Error detection and status monitoring are focused on terminals that exhibit suspicious patterns or error conditions, allowing the system to maintain high transaction integrity while concentrating computational resources only where needed rather than continuously monitoring all terminals equally.

AI summary
A terminal management device includes an acquisition unit, a detection unit, and a restriction unit. The acquisition unit acquires status information indicating the operating condition of the mobile terminal operated by a customer used for purchase processing of a commodity. The detection unit detects an error condition of the mobile terminal based on the status information acquired by the acquisition unit. The restriction unit restricts the purchase processing by the mobile terminal according to the number of error conditions of the mobile terminal detected by the detection unit.
