Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article transport systems face challenges in reducing the constraints on elastic deformability required for vibration suppression, as the elastic body must deform in the direction of vibration, which can be difficult due to space constraints.
Innovation Solution
The article transport body incorporates a damper portion with a guide portion, link mechanism, and an elastic body coupled to the link mechanism, allowing the elastic body to dampen the link mechanism's operation, thereby adjusting the deformation amount and direction, reducing the required elastic deformability and suppressing vibration transmission from the travel portion to the held article.

Engineering Contradiction Analysis
1Object-affected harmful factors
If an elastic body is sandwiched between two members to suppress vibration transmission, then vibration transmission is suppressed, but the elastic body requires high elastic deformability which is difficult to achieve due to space constraints
Solution Approach 1:
The patent changes the deformation direction of the elastic body from the vertical direction (direction of vibration) to the horizontal direction by introducing a link mechanism. The elastic body deforms horizontally while the link mechanism converts this to vertical vibration suppression, effectively using another dimension to resolve the space constraint problem.
Solution Approach 2:
The link mechanism acts as an intermediary between the elastic body and the two members. It converts the horizontal deformation of the elastic body into vertical displacement to suppress vibration transmission, allowing the elastic body to function without requiring large vertical deformation space.
2Object-affected harmful factors
If the elastic body deforms in the direction of vibration suppression, then vibration transmission is suppressed, but the deformation amount must be comparable to the relative displacement amount which increases space requirements
Solution Approach 1:
The patent redirects the deformation of the elastic body from the vertical dimension (where large deformation is needed for vibration suppression) to the horizontal dimension. The link mechanism then translates this horizontal deformation into vertical vibration suppression, reducing the required deformation amount in any single direction.
Solution Approach 2:
The patent changes the direction parameter of elastic body deformation from vertical to horizontal through the link mechanism. This parameter change allows the elastic body to achieve the necessary vibration suppression effect while requiring smaller deformation amounts, as the link mechanism provides mechanical advantage in converting the deformation.
3Adaptability or versatility
If constraints on placement space for the elastic body are reduced, then more flexible material selection is possible, but the structure becomes more complex
Solution Approach 1:
The link mechanism serves as an intermediary that decouples the elastic body from direct vertical loading. This allows the use of elastic bodies with smaller deformability since the link mechanism provides the necessary mechanical advantage, thereby expanding material selection flexibility while accepting increased structural complexity.

AI summary
A support portion includes: a first portion that is supported on a travel portion; a second portion that is coupled to a holding portion; and a damper portion that is provided between the first portion and the second portion. The damper portion includes: a guide portion that guides movement of the first portion relative to the second portion along a specific guiding direction; a link mechanism that is coupled to each of the first portion and the second portion, and that moves in conjunction with movement of the first portion relative to the second portion; and an elastic body. The elastic body is coupled to the link mechanism so as to dampen operation of the link mechanism.
