Solution Overview

Problem

Existing shopper assistance systems lack the ability to provide personalized and timely assistance based on shopper dwell time, leading to missed opportunities for promoting products and enhancing the shopping experience.

Innovation Solution

A shopper assistance system that utilizes a mobile wireless communications device and a shopper assistance server to track geographic position data and determine shopper dwell time, allowing for the provision of user interfaces and digital promotions tailored to the shopper's interests and location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional paper coupons are used for marketing, then product promotion can be achieved, but shopper assistance cannot be personalized or timely based on shopper behavior

Engineering Contradiction:
Improvepersonalization of shopper assistanceVSAvoidtimeliness of product promotion
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by tracking shopper geographic position and dwell time in real-time, enabling the server to proactively identify when a shopper is interested in a product (exceeding dwell time threshold) and immediately push personalized digital promotions to their mobile device before the shopper leaves the product area, thus achieving both personalization and timeliness

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring shopper behavior data (geographic position, dwell time) and using this information to dynamically adjust and deliver personalized promotions. The chatbot also provides feedback by engaging shoppers in conversation to understand their needs and offer relevant assistance, creating a closed-loop system that adapts to shopper preferences

Inventive Principle:
Principle #23Feedback

2Loss of information

If no tracking system is implemented, then system complexity is low, but shopper behavior data cannot be collected for personalized assistance

Engineering Contradiction:
Improveshopper behavior data collectionVSAvoidtracking system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system uses universal mobile devices (smartphones) that shoppers already carry, which serve multiple functions: geographic positioning via GPS, communication through the retailer app, and promotion delivery. This eliminates the need for specialized tracking hardware while still achieving comprehensive shopper behavior monitoring and personalized assistance

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

Solution Approach 2:

The system leverages the shopper's own mobile device and existing retailer application to collect behavior data and deliver promotions. The geographic positioning and communication functions are already built into the shopper's device, reducing system complexity while enabling detailed behavior tracking through the app's integration with the server

Inventive Principle:
Principle #25Self-service

3Productivity

If real-time shopper tracking is implemented, then personalized promotions can be delivered, but system operational complexity increases

Engineering Contradiction:
Improveeffectiveness of product promotionVSAvoidsystem operational complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The retailer server acts as an intermediary that centralizes the complex processing of shopper behavior data, geographic positioning information, and promotion delivery. Rather than distributing complexity across multiple components, the server consolidates data analysis, dwell time calculation, and promotion generation, simplifying the overall system architecture while enabling real-time personalized marketing

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A shopper assistance system may include a mobile device associated with a shopper, and a shopper assistance server. The server may, as the shopper moves along a path of travel within a physical store, cooperate with the mobile device to obtain geographic position data associated with a shopper position within the physical store, and determine a shopper dwell time at a given shopper position within the physical store based upon the geographic position data. The server may also determine a product for purchase adjacent the shopper based upon the given shopper position and cooperate with the mobile device to provide a user interface for providing shopper assistance with the product for purchase based upon the shopper dwell time. The server may also generate and communicate to the mobile device a digital promotion based upon the shopper dwell time.
