Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing transport systems using autonomous mobile robots face challenges in accurately delivering multiple transported objects to their correct destinations, particularly when different transport destinations are involved, leading to potential misdelivery.

Innovation Solution

The system employs a mobile robot equipped with detection mechanisms, such as IC tags and electronic medical record systems, to identify and manage transport destinations, and includes a host management device for route planning and control, ensuring accurate delivery by outputting destination mismatches and adjusting routes as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the mobile robot transports multiple transported objects simultaneously, then transport efficiency is improved, but the risk of misdelivery increases

Engineering Contradiction:

Improvetransport efficiencyVSAvoiddelivery accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system segments the transport process by associating each transported object with its own transport destination information. The mobile robot divides the delivery task into multiple independent delivery units, each tracked separately, allowing simultaneous transport of multiple objects to different destinations without confusion

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements feedback mechanisms where the mobile robot continuously monitors the location and status of each transported object during transit. The notification device provides real-time feedback to recipients about incoming deliveries, enabling the system to detect and correct potential misdelivery situations before they occur

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the mobile robot autonomously determines transport destinations, then operational complexity is reduced, but the risk of destination errors increases

Engineering Contradiction:

Improveautonomous operationVSAvoiddestination accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by pre-registering transport destination information for each transported object before the mobile robot begins its autonomous transport task. This includes pre-configuring recipient information and delivery locations, allowing the robot to follow predetermined accurate routes without real-time decision-making errors

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The notification device serves as an intermediary between the mobile robot and recipients. It verifies delivery information, communicates arrival status, and confirms proper delivery, acting as a mediator that ensures destination accuracy even when the robot operates autonomously

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A transport system is a transport system for transporting a transported object using a mobile robot that is autonomously moveable. The mobile robot transports a plurality of the transported objects. The transport system detects that a transport destination of the transported object is different from a receiving location. The transport system outputs that there is the transported object of a different transport destination to a recipient who is present at the receiving location.
