Solution Overview

Problem

Existing automatic moving vehicles face challenges in safely transporting objects with varying masses at high speeds, as they may encounter dangers or prolong movement times due to inappropriate speed and acceleration settings.

Innovation Solution

A moving body with a control device that adjusts speed and acceleration based on parameters like mass, size, and center of gravity of the loading object, using a driving device and a loading platform lifting mechanism to optimize transport conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the moving body travels at high speed when carrying a heavy object, then productivity is improved, but safety and reliability deteriorate

Engineering Contradiction:
Improvetravel speedVSAvoidsafety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies dynamics by making the speed and acceleration/deceleration of the moving body variable rather than fixed. The control device dynamically adjusts these parameters based on the mass of the loading object, allowing high speed for light objects and low speed for heavy objects, thus resolving the contradiction between productivity and safety

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters (speed and acceleration/deceleration) based on the mass parameter of the loading object. The control device sets different speed and acceleration profiles according to the load mass, enabling the system to optimize both productivity and safety by adapting parameters to the specific loading condition

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the moving body travels at low speed when carrying a light object, then safety is improved, but productivity deteriorates

Engineering Contradiction:
ImprovesafetyVSAvoidmovement time
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts speed based on load conditions, allowing the moving body to travel at high speed when carrying light objects, thus improving productivity while maintaining safety through conditional speed adjustment rather than uniformly low speed

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If the positioning member protrudes from the loading platform surface, then positioning accuracy is improved, but the risk of collision and damage increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidcollision risk
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The positioning member is designed to dynamically change its protrusion state based on the lifting condition of the loading platform. It protrudes when the platform is lifted to provide positioning accuracy, and retracts when the platform is lowered to avoid collision, resolving the contradiction between positioning accuracy and collision risk

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The positioning member protrudes in advance when the loading platform is lifted to ensure proper positioning of the loading object before transport begins, and retracts in advance before potential collision situations occur, applying preliminary action to prevent harmful effects

Inventive Principle:
Principle #10Preliminary action
