Solution Overview

Problem

Transport vehicles risk rollover when luggage is taken in or out, due to applied loads, especially when the vehicle's width is short relative to its wheelbase.

Innovation Solution

A transport system and method that utilize a connected transport robot and vehicle, where the robot takes in and out luggage while connected to the vehicle, using mechanisms like first and second connecting mechanisms and a manipulator to manage loads and prevent rollover by ensuring the vehicle's width is increased during these operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the transport vehicle has a short width relative to wheelbase, then the vehicle structure is compact, but the vehicle is prone to rollover when luggage is taken in or out

Engineering Contradiction:
Improvevehicle compactnessVSAvoidvehicle stability
Core Design Contradiction:
Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The transport robot acts as an intermediary between the luggage and the transport vehicle. The robot's manipulator performs the actual luggage handling operations while the vehicle remains connected to the robot through a connecting mechanism, distributing loads and preventing direct impact forces that could cause rollover

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the transport robot takes out luggage from the transport vehicle, then the luggage transport function is achieved, but a load is applied to the vehicle that may cause rollover

Engineering Contradiction:
Improveluggage transport efficiencyVSAvoidvehicle stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The transport robot and transport vehicle are merged into a connected operational unit. The connecting mechanism between the robot and vehicle allows them to work together as an integrated system, where the robot manipulator handles luggage while the vehicle provides stable support, combining the productivity of automated handling with the stability of the vehicle platform

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connecting mechanism serves as an intermediary structure between the robot and vehicle, transmitting and distributing loads during luggage handling operations to prevent direct force application that could cause vehicle rollover

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A transport system is a transport system that transports a luggage using a transport vehicle and a transport robot. In a state in which the transport robot and the transport vehicle are connected, the transport robot takes out the luggage from the transport vehicle, or stores the luggage in the transport vehicle.
