Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing object conveying systems experience vibrations and tilting issues when the vehicle member enters the mounting table due to wheel impacts on the rail bridging portion, leading to instability and potential damage.

Innovation Solution

The system employs a horizontal moving mechanism with first and second wheels moving along rails of different horizontal heights, allowing the mechanism to maintain a stable tilted posture and reduce impact by supporting the vehicle member without sudden angle or height changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the rail is dropped to a lower position to suppress wheel impacts and vibrations, then the vibration is reduced, but the vehicle member becomes tilted after completely entering the mounting table

Engineering Contradiction:

ImprovevibrationVSAvoidtilt

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The rail is divided into two segments: a first rail at a higher position and a second rail at a lower position. The wheels transition from the first rail to the second rail in a controlled manner, allowing the vehicle member to maintain stability while reducing vibrations during the transition process.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The solution introduces a vertical dimension to the rail configuration by positioning the first and second rails at different heights. This vertical arrangement allows the vehicle member to transition smoothly between height levels, reducing horizontal impacts and vibrations while maintaining proper alignment.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If the wheels enter the rail bridging portion at high speed, then the conveyance efficiency is maintained, but impacts and vibrations are generated

Engineering Contradiction:

Improveconveyance efficiencyVSAvoidimpact

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The bridging portion of the rail is designed with a curved profile instead of a sharp transition. This curvature allows the wheels to roll smoothly over the transition point, reducing impact forces while maintaining continuous motion and conveyance efficiency.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The rail structure incorporates a bridging portion that anticipates the wheel transition and provides a gradual, cushioned entry. This pre-designed transition zone reduces shock and vibration before the wheels fully engage the second rail, preventing harmful impacts.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The disclosure discloses an object conveying system which includes an object conveying apparatus and a mounting table. The object conveying apparatus includes a traveling member, the vehicle member, and a transporting member. A rail which extends along a horizontal direction is disposed between the object conveying system and the mounting table. A horizontal moving mechanism of the vehicle member moves back and forth along the rail. The rail includes a first rail and a second rail having different horizontal heights in an up-down direction and extending along the horizontal direction. While the horizontal moving mechanism is moving to the side away from the object conveying apparatus, a first wheel of the horizontal moving mechanism moves along the first rail, and a second wheel of the horizontal moving mechanism moves along the second rail.
