Solution Overview

Problem

In modern retail environments, customers often face difficulties due to insufficient employee assistance, high employee turnover rates, and challenges with maintaining store organization and security, leading to low customer satisfaction and increased competition from online shopping.

Innovation Solution

A shopping facility assistance system utilizing motorized transport units controlled by a central computer system, which can lead or follow users, manage inventory, and perform tasks such as retrieving shopping carts, to enhance customer experience and operational efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If more employees are hired to assist customers during peak hours, then customer service quality improves, but labor cost increases

Engineering Contradiction:
Improvecustomer service availabilityVSAvoidlabor cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The shopping cart system provides self-service capabilities through autonomous navigation, product location guidance, and automated cart return functionality. The cart independently performs tasks that would otherwise require employee intervention, such as navigating to customers, guiding them to products, and returning to designated areas after use.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical system of human employees with an automated motorized cart system equipped with sensors, processors, and communication modules. The cart system uses electronic control to perform assistance functions, substituting human labor with an automated mechanical-intelligent system.

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

2Reliability

If employees are extensively trained to provide adequate customer support, then service quality improves, but training time and cost increase

Engineering Contradiction:
Improveemployee knowledgeVSAvoidtraining duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The shopping cart acts as an intermediary between the central system and the customer, providing product information, navigation guidance, and assistance functions. The cart contains a database of product information and uses sensors to locate items, eliminating the need for employees to memorize and convey this information.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system pre-loads product information, store layout data, and customer preferences into the cart's memory before the shopping trip begins. The cart is prepared in advance with all necessary information and capabilities, so no training is needed during the actual shopping interaction.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the store increases its size to offer more products, then product variety improves, but customer navigation difficulty increases

Engineering Contradiction:
Improveproduct assortmentVSAvoidstore navigation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system adds an informational dimension to the physical shopping environment by incorporating GPS-like tracking, digital mapping, and real-time location data. The cart provides three-dimensional spatial awareness and navigation guidance, transforming the large physical space into an easily navigable environment through digital overlays and directional instructions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The shopping cart continuously receives feedback from sensors, customer inputs, and the central system to update its navigation instructions and product location information in real-time. The system monitors customer movement, adjusts routing dynamically, and provides ongoing guidance based on current store conditions and customer preferences.

Inventive Principle:
Principle #23Feedback

4Reliability

If monitoring systems are installed to prevent theft and maintain organization, then store security improves, but system complexity increases

Engineering Contradiction:
Improvestore securityVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The shopping cart system performs multiple functions simultaneously: it provides customer assistance, tracks products, monitors store conditions, prevents theft through item scanning, and manages its own navigation and charging. This multi-functional approach consolidates what would otherwise require separate monitoring systems into a single integrated platform.

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

Solution Approach 2:

The cart system autonomously monitors its own location, tracks items in the customer's cart, detects unauthorized removal of products, and communicates with the central system without requiring separate monitoring infrastructure. The security functions are self-contained within the cart's sensor and processing capabilities.

Inventive Principle:
Principle #25Self-service

AI summary

A shopping facility assistance system includes a plurality of motorized transport units, a plurality of user interface units, and a central computer system having a network interface such that the central computer system wirelessly communicates with one or both of the motorized transport units and the user interface units. The central computer system is configured to control movement of the motorized transport units through a shopping facility space based at least on inputs from the user interface units. More particularly, the central computer system controls movement of the motorized transport units such that a given one of the plurality of motorized transport units selectively leads a user to a destination within the shopping facility or follows the user within the shopping facility as determined by the central computer system. By one approach, the motorized transport units move through the shopping facility via a plurality of preferred pre-determined path segments.
