Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stock tracking systems lack efficient methods for generating and visualizing a virtual environment of a store, particularly in real-time, which hinders accurate inventory management and product monitoring.
Innovation Solution
A method involving a mobile robotic system that autonomously navigates within a facility, captures images using an optical sensor, and a computer system that processes these images to construct and update a three-dimensional map of inventory structures, annotating them with stock conditions, enabling a virtual representation of the store environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mobile robotic system autonomously navigates and captures images to construct a three-dimensional map in real-time, then the accuracy and timeliness of inventory monitoring is improved, but the system complexity and computational requirements increase
Solution Approach 1:
The system divides the inventory monitoring task into discrete segments: autonomous navigation, image capture, image processing, and three-dimensional map construction. Each segment is handled by specialized components (mobile robotic system with optical sensors, computer system with image processing algorithms), reducing overall system complexity while maintaining high measurement precision through focused functional decomposition.
Solution Approach 2:
The system creates a virtual three-dimensional copy of the physical inventory environment. Instead of directly manipulating or physically inspecting actual inventory, the robotic system captures images and constructs a digital three-dimensional map that replicates the inventory structure and stock conditions, enabling accurate monitoring through virtual representation without direct physical intervention.
2Reliability
If store associates remotely view inventory through a portal system, then information security is improved by reducing human exposure, but the complexity of the visualization system increases
Solution Approach 1:
The system introduces a portal as an intermediary layer between the inventory monitoring system and store associates. The portal receives processed inventory data and presents it through a user-friendly interface, enabling secure remote access for store associates without exposing them to sensitive backend systems or physical inventory areas, thus enhancing information security while managing visualization complexity through standardized communication protocols.

AI summary
One variation of a method includes: accessing a sequence of images of an inventory structure captured by a mobile robotic system during a scan cycle within a facility; detecting a set of features, representing a product descriptor, proximal a slot in an image in the sequence of images; retrieving a set of template features of a product type associated with the product descriptor from a database of template features; detecting absence of product units of the product type in the slot based on absence of features analogous to the set of template features in the image; constructing a three-dimensional image of the inventory structure based on the sequence of images; annotating the three-dimensional image with a marker representing absence of product units of the product type in the slot; and serving the three-dimensional image of the inventory structure to a portal accessed by an associate affiliated with the facility.
