Order Cancellation Timing via Display Terminal Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network-based purchase ordering systems face challenges in allowing timely cancellation of orders and efficient confirmation processes, particularly when the person placing the order is different from the one managing orders, leading to potential wrong orders and increased time required for confirmation.
Innovation Solution
An information processing method that receives order information, determines the existence of a corresponding display terminal, transmits acceptance message, and starts a cancellation period upon status information receipt, enabling cancellation without requiring manual confirmation from the checking person.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the cancellation period starts immediately after order placement, then the consumer can cancel wrong orders timely, but the consumer may not be aware of the order yet leading to premature cancellation
Solution Approach 1:
The system uses feedback from the display terminal to determine when the consumer has actually seen the order information. The cancellation period is triggered only after the display terminal sends status information indicating the message was displayed, ensuring the consumer is aware of the order before the cancellation period begins.
Solution Approach 2:
The system performs preliminary action by sending the acceptance message to the display terminal before starting the cancellation period. The message is displayed in advance, and only after confirmation that the display terminal has received and displayed the message does the cancellation period commence.
2Reliability
If manual confirmation from checking person is required, then order accuracy can be verified, but the ordering process time increases significantly
Solution Approach 1:
The system implements self-service by automatically verifying order delivery to the consumer. The display terminal automatically sends status information when the message is displayed, and the server automatically starts the cancellation period based on this status, eliminating the need for manual confirmation by a checking person.
Solution Approach 2:
The manual mechanical confirmation process is replaced with an automated electronic system. The status information transmission from the display terminal substitutes for manual verification, and the automated server processing replaces manual order management, significantly reducing process time while maintaining accuracy.
3Reliability
If the system waits for status information from display terminal, then cancellation period starts at appropriate time, but there is delay in starting the cancellation period
Solution Approach 1:
The system maintains continuous action by immediately sending the acceptance message to the display terminal upon receiving the order. The display terminal continuously monitors and sends status information as soon as the message is displayed, ensuring the cancellation period starts with minimal delay while maintaining timing accuracy.

AI summary
Order information indicating a purchase order is received from an ordering device. Whether a display terminal corresponding to the ordering device from which the order information has been sent exists or not is determined using information which indicates correspondences between ordering devices and display terminals. Message information indicating acceptance of the purchase order indicated in the order information is transmitted to the corresponding display terminal. It is determined whether status information indicating that the message information was displayed on the display of the corresponding display terminal has been received from the corresponding display terminal or not. A cancellation period during which a process for canceling the purchase order indicated in the order information is accepted is started upon reception of the status information.
