Solution Overview

Problem

Existing methods fail to provide centralized management of shopping lists across multiple devices and users while offering real-time order progress and dynamically adjusting interactive user interfaces for efficient order completion.

Innovation Solution

A computing system that intelligently splits data payloads among shopper devices based on shopper characteristics, item features, and real-time progress, using machine-learned models to optimize data distribution and update user interfaces for efficient order completion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If shopping lists are managed independently on each device, then device autonomy is maintained, but data duplication and resource waste occur

Engineering Contradiction:
Improvedevice autonomyVSAvoiddata duplication
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The system segments the shopping list data into a centralized data structure that is logically divided but physically stored in one location. Multiple devices can access different portions of the segmented data without duplicating the entire data set, resolving the contradiction between device autonomy and data duplication.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A centralized data structure acts as an intermediary between multiple shopping list devices. This intermediary enables devices to access shopping list data without direct duplication, while maintaining each device's operational independence through controlled access mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If real-time order progress tracking is implemented across multiple devices, then order visibility is improved, but computational overhead increases

Engineering Contradiction:
Improveorder visibilityVSAvoidcomputational overhead
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

Instead of maintaining full real-time copies of order progress data on each device, the system creates selective copies or projections of relevant order information. This reduces computational overhead while maintaining adequate order visibility for each user's needs.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The centralized data structure serves multiple functions simultaneously: it stores order progress, enables real-time tracking, supports multiple device access, and reduces computational load. This multi-functionality resolves the contradiction by achieving order visibility without proportional increases in computational overhead.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If shopping lists are dynamically adjusted based on multiple user selections, then order efficiency is improved, but system complexity increases

Engineering Contradiction:
Improveorder efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system implements dynamic adjustment of shopping lists based on user selections through a centralized data structure that automatically updates. This dynamic capability improves order efficiency by adapting to user needs in real-time while the centralized nature of the data structure manages complexity rather than distributing it across multiple devices.

Inventive Principle:
Principle #15Dynamics
