Article Support Mechanism for Vibration Damping and Tilt Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article transport vehicles face challenges in minimizing vibrations transmitted to articles and ensuring proper orientation during transfer, as unbalanced loads can cause tilting, leading to inadequate placement due to the offset centroid of the article.
Innovation Solution
An article transport vehicle is designed with an elastic support mechanism between the article support portion and the connection portion, along with a guide mechanism that allows vertical movement while restricting swinging, ensuring the article support portion moves parallel to the connection portion, thus minimizing vibrations and preventing tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the elastic modulus of the damper element is increased to restrict the article from tilting, then the tilting is suppressed, but it becomes difficult to appropriately suppress vibrations transmitted to the article
Solution Approach 1:
The support mechanism is divided into two distinct functional components: a damper element for vibration suppression and a guide mechanism for orientation control. The damper element (36) with optimized elastic modulus handles vertical vibration damping, while the guide mechanism (37) separately manages tilting prevention through geometric constraints, allowing both functions to operate independently without conflicting requirements
Solution Approach 2:
The guide mechanism acts as an intermediary between the damper element and the article, translating the vertical movement capability provided by the damper into constrained parallel movement that prevents tilting. The guide mechanism mediates the conflict by allowing vertical displacement while maintaining orientation through its geometric structure
2Object-affected harmful factors
If the damper element is made more flexible to suppress vibrations, then vibrations are reduced, but the article may tilt due to unbalanced loads
Solution Approach 1:
The support mechanism is divided into two distinct functional components: a damper element for vibration suppression and a guide mechanism for orientation control. The damper element (36) with optimized elastic modulus handles vertical vibration damping, while the guide mechanism (37) separately manages tilting prevention through geometric constraints, allowing both functions to operate independently without conflicting requirements
Solution Approach 2:
The guide mechanism acts as an intermediary between the damper element and the article, translating the vertical movement capability provided by the damper into constrained parallel movement that prevents tilting. The guide mechanism mediates the conflict by allowing vertical displacement while maintaining orientation through its geometric structure

Function Achieved in This Case
This configuration effectively suppresses vibrations and ensures accurate placement of articles by maintaining the appropriate orientation, even when the centroid is offset, preventing transfer failures.

AI summary
An article transport vehicle includes a travel body; a holding device that holds an article; and a lift device that is on the travel body, and that raises and lowers the holding device with respect to the travel body. The holding device includes: a connection portion connected to the lift device and an article support portion that supports the article; an elastic support mechanism that is between the article support portion and the connection portion, and that supports the article support portion against the connection portion while being elastic in a vertical direction, and a guide mechanism that guides the article support portion in the vertical direction with respect to the connection portion. The guide mechanism allows the article support portion to move parallel with the vertical direction with respect to the connection portion and restricts swinging of the article support portion with respect to the connection portion.
