Solution Overview

Problem

Modern retail stores face challenges in providing adequate customer assistance and maintaining a conducive shopping environment due to insufficient staff, high employee turnover, and peak-hour demands, leading to issues like unanswered customer questions, messy aisles, inventory misplacement, and theft, which negatively impact customer satisfaction.

Innovation Solution

A shopping assistance system comprising motorized transport units controlled by a central computer system, equipped with user interfaces and 3D scanners, that can autonomously move through the store to assist customers and workers by managing inventory, cleaning, and maintaining store appearance, and providing information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If more employees are hired to assist customers and maintain the store, then customer service quality improves, but labor costs and operational complexity increase

Engineering Contradiction:
Improvecustomer service qualityVSAvoidoperational complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables self-service monitoring where the automated depth detection system continuously tracks product inventory and placement without human intervention. Sensors and image processing algorithms automatically detect product depth, generate alerts when products need restocking, and notify relevant personnel, eliminating the need for manual inventory checks by employees.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual inventory monitoring and product placement verification by employees is replaced with an automated electronic system using depth sensors, image capture devices, and computer processing. The mechanical action of employees physically checking shelves is substituted with optical and electronic detection mechanisms that continuously monitor product status.

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

2Loss of energy

If employees are reduced to lower costs, then operational expenses decrease, but customer assistance and store maintenance quality deteriorate

Engineering Contradiction:
Improveoperational expensesVSAvoidcustomer assistance quality
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The system performs self-monitoring of inventory levels and product placement, automatically generating notifications when intervention is needed. This maintains store maintenance quality without requiring constant employee presence, as the system independently tracks and reports issues.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system provides continuous feedback through automated alerts and notifications to employees and management when products need restocking or repositioning. This feedback loop ensures timely responses to inventory issues, maintaining service reliability even with reduced staff by directing their attention only when needed.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If manual inventory monitoring is performed frequently, then product placement accuracy improves, but time consumption and labor requirements increase

Engineering Contradiction:
Improveproduct placement accuracyVSAvoidtime consumption
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The monitoring system operates continuously without interruption, constantly tracking product depth and placement on shelves. Unlike periodic manual checks, the automated system provides uninterrupted surveillance, ensuring placement accuracy is maintained at all times without consuming employee time.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Manual visual inspection and physical measurement of product placement by employees is replaced with automated depth sensors and image capture devices that precisely measure product positions and depths electronically, achieving high accuracy without human time investment.

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

4Productivity

If automated monitoring systems are deployed, then labor requirements decrease, but system complexity and initial investment increase

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

Solution Approach 1:

The monitoring system is divided into modular functional components: depth detection sensors, image capture devices, processing units, communication modules, and alert generation systems. Each module performs a specific function and can be independently configured or replaced, reducing overall system complexity through functional segmentation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system is designed to monitor multiple product types, shelf configurations, and store layouts using the same core technology platform. The depth detection and image processing algorithms are universally applicable across different retail environments, reducing complexity by avoiding the need for specialized systems for each application.

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

AI summary

Methods and apparatuses are provided for use in monitoring product placement within a shopping facility. Some embodiments provide an apparatus configured to determine product placement conditions within a shopping facility, comprising: a transceiver configured to wirelessly receive communications; a product monitoring control circuit coupled with the transceiver; a memory coupled with the control circuit and storing computer instructions that when executed by the control circuit cause the control circuit to: obtain a composite three-dimensional (3D) scan mapping corresponding to at least a select area of the shopping facility and based on a series of 3D scan data; evaluate the 3D scan mapping to identify multiple product depth distances; and identify, from the evaluation of the 3D scan mapping, when one or more of the multiple product depth distances is greater than a predefined depth distance threshold from the reference offset distance of the product support structure.
