IoT Shopping Route and Payment Coordination for Household Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT systems, navigation systems, and virtual payment systems lack a cohesive interface, leading to inefficiencies, inaccuracies, and security risks in managing shopping lists and transactions among household members, as they do not consider real-time locations, routes, or personalized restrictions.
Innovation Solution
A Family Pickup Interface (FPI) integrates IoT, navigation, and virtual payment systems through a Home Grouping Application (HGA) to optimize shopping requests by determining the most convenient user based on location and route, applying personalized transaction restrictions, and ensuring efficient navigation and secure payment transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If IoT systems operate independently without integration to navigation and virtual payment systems, then device complexity is reduced, but shopping request assignment accuracy and efficiency deteriorate due to lack of real-time location and route information
Solution Approach 1:
The patent merges IoT shopping list management, navigation systems, and virtual payment systems into a unified ecosystem. The smart refrigerator (IoT device) communicates with navigation applications on user devices to determine real-time location and route information, then integrates with virtual payment systems to enable contactless payments at merchants along the navigation route, creating a cohesive shopping fulfillment system that improves efficiency without requiring users to manually coordinate multiple separate systems
Solution Approach 2:
The navigation system acts as an intermediary between the IoT shopping list management and virtual payment systems. It receives shopping list data from IoT devices, determines optimal merchants based on real-time location and route, and triggers virtual payment processes, thereby coordinating the three systems without requiring direct complex integration between each pair
2Measurement precision
If the system integrates real-time location tracking and route optimization for shopping requests, then shopping assignment accuracy improves, but information processing requirements and system complexity increase
Solution Approach 1:
The navigation application serves multiple functions: it provides real-time location tracking, determines optimal routing to merchants, identifies suitable merchants based on shopping lists, and coordinates payment processes. This multi-functional approach consolidates what would otherwise require separate specialized systems, improving location accuracy without proportionally increasing overall system complexity
3Ease of operation
If virtual payment methods are shared among multiple household members without restrictions, then ease of operation for group shopping improves, but security risks increase due to potential unauthorized use
Solution Approach 1:
The system implements dynamic authorization for shared virtual payment methods. When a user accepts a shopping request, the system temporarily enables payment capability for that specific transaction and merchant, then automatically disables it afterward. This dynamic on-demand authorization allows convenient sharing among household members while maintaining security through time-limited, purpose-specific access control
4Loss of time
If the system assigns shopping requests based on real-time navigation routes, then loss of time for duplicate purchases is reduced, but computational requirements for route analysis increase
Solution Approach 1:
The system performs partial route analysis by focusing only on identifying merchants that lie along the user's current navigation route, rather than performing exhaustive optimization of the entire route. This selective approach sufficiently prevents duplicate shopping trips by catching obvious route alignments without requiring computationally intensive complete route re-optimization
Data Source
AI summary
Systems and methods of a smart transaction system with IoT integration for purchase requests by way of a cohesive interface integrating IoT systems, navigation systems, and virtual payment systems are disclosed. Initiation of a navigation route for a navigation device associated with a user of a household is detected. An IoT device-managed shopping list shared with one or more user devices associated with the household is accessed. A nearby merchant which sells items from the shopping list is identified. A route deviation score for the merchant location is determined based on the navigation route. If the route deviation score does not meet or exceed a predetermined deviation threshold associated with the navigation device, the shopping list and navigation instructions to the merchant location as an intermediary stop on the route are transmitted to the navigation device. A digital financial transaction for a user device associated with the user is enabled, with restrictions based on a provided shared virtual payment method, at the merchant location.
