Solution Overview

Problem

Updating and maintaining accurate data for sets of physical objects in dynamic environments is challenging, particularly when elements are not processed through standard channels, leading to errors and inefficiencies.

Innovation Solution

Autonomous robot systems equipped with image capturing devices and machine vision capabilities roam facilities to detect absent objects, transmit identifiers to computing systems, and trigger corrective actions, including inventory adjustments and object replenishment across geographically distributed locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual updating processes are used for physical objects, then operational simplicity is maintained, but data accuracy deteriorates when elements are not channeled through normal processes

Engineering Contradiction:
Improvedata accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system enables self-service through autonomous robots that automatically detect, identify, and report the status of physical objects without human intervention. The robots autonomously navigate facilities, capture images, recognize objects using machine vision, and transmit data to computing systems, eliminating the need for manual updating while maintaining high data accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical processes for tracking physical objects are replaced with an automated system comprising autonomous robots equipped with image capturing devices, machine vision algorithms, and wireless communication modules. This substitution transforms the mechanical manual updating process into an automated optical and electronic system, significantly improving data accuracy.

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

2Reliability

If autonomous robot systems are deployed to detect and track physical objects, then data accuracy improves, but device complexity increases

Engineering Contradiction:
Improveinventory accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system is segmented into distinct functional modules: autonomous robots for navigation and detection, image capturing devices for data collection, machine vision systems for object recognition, wireless communication modules for data transmission, and computing systems for data processing and inventory management. This segmentation allows each component to be optimized independently while working together to achieve high inventory accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The autonomous robots are designed as multi-functional units that can perform multiple tasks including autonomous navigation, image capture, object detection, identification, and wireless communication. This universality reduces the need for separate specialized devices, thereby managing system complexity while maintaining high reliability for inventory tracking.

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

3Measurement precision

If real-time detection of absent objects is implemented, then inventory management accuracy improves, but loss of time in processing increases

Engineering Contradiction:
Improveinventory status accuracyVSAvoiddetection and processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The autonomous robots continuously navigate through facilities and detect physical objects in real-time without interruption. The system maintains continuous monitoring through persistent image capture, ongoing machine vision processing, and constant wireless data transmission, ensuring inventory status is updated continuously rather than periodically, thus improving accuracy without significant time loss.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system performs preliminary detection and identification of physical objects before inventory discrepancies occur. By continuously monitoring object presence and status in advance, the system can detect absent objects early and trigger replenishment actions before stockouts impact operations, improving inventory accuracy while minimizing processing delays.

Inventive Principle:
Principle #10Preliminary action

AI summary

Described in detail herein are systems and methods for detecting absent like physical objects at a first facility and replenishing the like physical objects from the second facility to the first facility. The system includes an autonomous robot device configured to detect absent like physical objects at a first facility and transmit an identifier associated with the like physical objects to a first computing system. The first computing system determines the need for the addition of the like physical objects in the first facility and transmits the data associated with the like physical objects to the second computing system. The second computing system corrects a perpetual inventory error associated with the like physical objects based on the received data and transmits instructions to an autonomous robot picker disposed at a second facility to replenish the like physical objects at the first facility. The autonomous robot picker locates, picks up and carries the like physical objects at the second facility to a conveyer belt. The like physical objects are transported from the second facility to the first facility.
