Solution Overview

Problem

In modern retail environments, there is a need to enhance customer experience and convenience, as customers often face unattended assistance during peak hours due to insufficient trained staff, leading to issues like abandoned shopping carts, messy aisles, incorrect inventory placement, and theft, which can result in low customer satisfaction and increased competition from online shopping.

Innovation Solution

A shopping assistance system utilizing automated, robotic motorized transport units controlled by a central computer system to assist customers and workers by moving items, maintaining store cleanliness, and optimizing inventory placement, equipped with user interfaces and location detection systems to navigate and perform tasks autonomously.

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 enables customers to serve themselves through automated features including product location guidance, inventory checking, and navigation assistance, eliminating the need for additional staff during peak hours while maintaining service quality

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mechanical system of human employees providing customer assistance is replaced with an automated electronic system embedded in shopping carts, which provides guidance, product information, and navigation services without requiring additional human labor

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

2Productivity

If automated systems are deployed to assist customers and manage inventory, then operational efficiency improves, but system complexity increases

Engineering Contradiction:
Improveoperational efficiencyVSAvoidautomation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The shopping cart system performs multiple functions including customer guidance, inventory tracking, theft prevention, and data collection within a single integrated platform, improving operational efficiency across multiple store functions without requiring separate complex systems for each task

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

Solution Approach 2:

The shopping cart acts as an intermediary device between customers, store inventory systems, and management systems, facilitating automated information exchange and coordination while simplifying the overall system architecture through a centralized communication hub

Inventive Principle:
Principle #24Intermediary (Mediator)
