Article Transport Vehicle Shake Prevention With Vertical Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article transport vehicles struggle to prevent articles from shaking in directions orthogonal to the vertical direction while maintaining effective vibration mitigation in the vertical direction, as supporting mechanisms in orthogonal directions hinder the elastic body's vibration-mitigating function.
Innovation Solution
An article transport vehicle equipped with a shake prevention mechanism that includes an abutting portion and an abutting support portion, where the abutting portion abuts against the article's side surface to prevent shaking and is elastically supported in the vertical direction, allowing the first elastic support portion to effectively mitigate vertical vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a mechanism is provided to support the article in the orthogonal direction to suppress shaking, then the article stability is improved, but the vertical movement of the article is restricted which hinders the function of the elastic body in mitigating vertical vibration transmission
Solution Approach 1:
The support mechanism is divided into two independent parts: the first elastic support portion that supports the article holding portion in the vertical direction, and the second elastic support portion that supports the abutting portion also in the vertical direction. This segmentation allows each part to independently perform its function without interfering with the other, enabling orthogonal shake prevention while maintaining vertical vibration mitigation.
Solution Approach 2:
The abutting portion acts as an intermediary element that prevents orthogonal shaking by contacting the article's side surface, while the second elastic support portion serves as a mediator that allows this abutting portion to move vertically independently. This intermediary structure enables the abutting portion to perform its shake prevention function without restricting the article's vertical movement, thus preserving the first elastic support portion's vibration mitigation capability.
2Stability of the object's composition
If the abutting portion is rigidly fixed to prevent orthogonal shaking, then the article stability is improved, but the article cannot move vertically which reduces the effectiveness of vibration mitigation
Solution Approach 1:
The support structure transitions from a static rigid connection to a dynamic system where the abutting portion can move vertically independently through the second elastic support portion. This dynamic design allows the abutting portion to maintain contact with the article for shake prevention while accommodating vertical movements, thus resolving the contradiction between stability and movement capability.
Solution Approach 2:
The support characteristics are changed by introducing elasticity to both support portions. The first elastic support portion provides vertical compliance for vibration mitigation, while the second elastic support portion provides vertical compliance for the abutting portion. This parameter change from rigid to elastic supports enables both orthogonal stability and vertical movement freedom.
