Cross-Platform Shopping List Aggregation via Mediator Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online and network shopping systems are limited in scope and functionality, as users can only create and share shopping lists within specific websites, with no ability to receive comments, opinions, or exposure to other users, and are restricted to purchasing items from predefined lists.
Innovation Solution
A network-based marketplace system with client-server architecture allows users to create and share shopping item lists among community groups, enabling members to provide reviews, recommendations, and purchase items from a shared electronic shopping cart across multiple vendors, with customizable rules and roles for list management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users create personal shopping carts or item lists on specific e-commerce websites, then they can shop for items within that website's catalog, but they cannot share or collaborate on shopping lists with other users outside the website's ecosystem
Solution Approach 1:
The patent introduces a centralized server as an intermediary that receives shopping list data from multiple e-commerce websites and presents it to users through a unified interface. This mediator layer enables cross-website shopping list sharing without requiring direct integration between websites, resolving the contradiction by adding sharing capability while managing complexity through centralization.
Solution Approach 2:
The system creates a universal shopping list platform that works across multiple e-commerce websites simultaneously. The server aggregates product data, pricing, and availability from different vendors into a single collaborative shopping list interface, enabling users to shop across websites while maintaining a unified list - achieving versatility without requiring each user to manage separate lists on each platform.
2Ease of operation
If users are restricted to purchasing items from predefined lists on specific websites, then transaction processing is simplified, but user engagement and collaborative shopping experience are limited
Solution Approach 1:
The system performs preliminary actions by pre-aggregating product information, pricing, and availability from multiple e-commerce websites into a unified shopping list before the user makes purchasing decisions. This advance preparation allows users to review and compare items across vendors in one place, improving shopping efficiency while maintaining simple transaction processing when users are ready to purchase.
Solution Approach 2:
The patent merges multiple shopping experiences and product catalogs into a single unified interface. By combining item lists from different e-commerce platforms into one collaborative list with consolidated pricing and availability information, the system improves productivity by reducing the time users would otherwise spend switching between websites, while keeping the actual purchase process simple through integrated checkout.
3Adaptability or versatility
If users cannot access or modify items in other users' shopping carts, then cart security and data integrity are maintained, but collaborative shopping and community engagement are prevented
Solution Approach 1:
The system applies different access levels and permissions to different users within the same shopping list environment. Each user can have customized rights - some may only view items, others may add or remove items, and administrators may have full control. This localized quality control enables collaboration while maintaining data integrity through role-based access management.
Solution Approach 2:
The server implements feedback mechanisms that notify users of changes made to the shopping list by other users. When items are added, removed, or modified, the system communicates these changes back to all participants, allowing collaborative shopping while maintaining transparency and data integrity through real-time synchronization and user awareness of list modifications.
Data Source
AI summary
A system receives item data corresponding to an item list from a user. The item list may include one or more items. The system communicates the item list to a community group associated with the user and the system then receives member data from one or more members of the community group, wherein the member data is associated with the one or more items on the item list.
