Real-time Order Notification System with QR Code Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transaction and order fulfillment systems are passive, requiring consumers to manually request status updates and lack a seamless mechanism for modifying orders, with proprietary interfaces that necessitate multiple subscriptions and manual identification processes.
Innovation Solution
A real-time order notification system that dynamically delivers changes in order state to a customer's mobile device, using an event manager to broadcast updates and generate QR codes for easy order identification and modification, allowing customers to receive active updates and make changes directly through a mobile interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If consumers manually request status updates through proprietary interfaces, then order status information can be obtained, but the process is passive and requires multiple subscriptions and manual identification
Solution Approach 1:
The system enables self-service by automatically pushing order status updates to consumers without requiring manual requests. The consumer provides identification once, and the system subsequently delivers status information autonomously, eliminating the need for repeated manual identification and interface interactions.
Solution Approach 2:
The system implements feedback by establishing a push notification mechanism where the business system automatically sends order status changes to the consumer's device. This creates an active feedback loop where information flows from the system to the consumer in real-time, rather than requiring the consumer to repeatedly query for updates.
2Loss of information
If consumers repeatedly log into interfaces to check order status, then current status can be obtained, but transaction efficiency is reduced due to multiple manual steps
Solution Approach 1:
The system ensures continuity of useful action by maintaining a persistent connection between the business system and the consumer's device. Order status updates are delivered continuously as changes occur, eliminating the need for repeated login and status check actions, thereby maintaining continuous information flow without interrupting other transaction activities.
Solution Approach 2:
The automated push notification system performs the information delivery function autonomously, freeing the consumer from repeated manual interactions. This self-service mechanism continuously provides status information without consuming the consumer's time or reducing overall transaction productivity.
3Loss of information
If proprietary interfaces are used for each business, then business-specific order tracking is achieved, but consumers must subscribe to multiple different interfaces
Solution Approach 1:
The system achieves universality by implementing a standardized push notification interface that can handle order tracking across multiple businesses. Instead of requiring separate proprietary interfaces for each business, a single universal interface receives standardized notifications from various business systems, consolidating multiple functions into one interface and reducing the number of subscriptions required.
4Reliability
If manual identification is required for order modification, then security is maintained, but ease of operation is reduced and transaction efficiency is lowered
Solution Approach 1:
The system applies preliminary action by collecting and verifying consumer identification information once at the beginning of the interaction. This preliminary identification step is stored and reused for subsequent order status updates and modifications, maintaining security and identification accuracy while eliminating the need for repeated manual identification during the transaction process.
Data Source
AI summary
Real-time order information is published to a server as an order is being placed for a customer and while the order is being fulfilled. The server dynamically pushes in real time the change in state of the order as the order is being fulfilled to a mobile device being operated by the customer.
