Solution Overview

Problem

Existing online concierge systems fail to provide effective assistance to users seeking information about items or solutions for specific problems, often requiring users to conduct research or contact retailers directly.

Innovation Solution

An online concierge system utilizing machine learning to analyze user inquiries through natural language processing and image recognition, routing them to appropriate retailers or shoppers with domain expertise, and suggesting relevant products or services based on user profiles and historical data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If users contact retailers directly or conduct research themselves to get assistance with item-related questions, then users can obtain information, but user time and effort are significantly consumed

Engineering Contradiction:
Improveaccess to item informationVSAvoiduser research time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system enables self-service by allowing users to submit inquiries through the concierge interface, which are then automatically routed and answered by appropriate shoppers or retailers without requiring users to manually contact multiple parties or conduct their own research

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The online concierge system acts as an intermediary between users and retailers, receiving user inquiries, analyzing them using natural language processing and image recognition, and automatically routing them to the most appropriate shoppers or retailers who can provide accurate information

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the online concierge system manually routes inquiries to retailers or shoppers, then assistance can be provided, but system complexity and routing accuracy decrease

Engineering Contradiction:
Improveinquiry routingVSAvoidrouting accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system replaces manual mechanical routing processes with automated machine learning models including natural language processing to analyze inquiry text and image recognition models to process uploaded images, enabling accurate automatic routing without human intervention

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates digital copies of user inquiries including text content and images, processes these copies through multiple machine learning models simultaneously, and uses the analysis results to determine the most appropriate routing destination without requiring physical or manual handling of the actual inquiry

Inventive Principle:
Principle #26Copying

3Measurement precision

If the system analyzes both text and images using machine learning models, then routing accuracy improves, but computational resources and processing time increase

Engineering Contradiction:
Improveinquiry classification accuracyVSAvoidcomputational resource consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system applies partial action by using different levels of analysis for different inquiries - applying both natural language processing and image recognition models when needed, while potentially using simpler routing logic for straightforward queries, thus optimizing resource consumption based on inquiry complexity

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A system or a method for intelligently routing user inquiries to knowledgeable retail shoppers using machine learning. Upon receiving an inquiry from a client device that includes both text and image content, the system applies machine learning models to identify item categories referenced in the text and shown in the image. The system uses an item availability model—trained on historical retailer inventory data—to identify a retailer likely to carry items in the identified categories and transmits suggestion information to the user's device, prompting a user interface that recommends the retailer. The system selects a shopper associated with the retailer who has subject matter expertise in the relevant item categories. Expertise is determined using a machine-learned model trained on labeled data from historical shopper orders. The system then forwards the user inquiry to the expert shopper's device, enabling direct communication and facilitating more accurate, personalized retail assistance.
