Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport vehicles in semiconductor manufacturing plants face issues with lateral swing suppression devices causing wear and dust generation due to contact with containers, which are not adequately addressed in existing technologies.
Innovation Solution
A transport vehicle equipped with a lateral swing suppression device featuring an abutment roller with a continuous concave groove along its periphery, designed to rotate and avoid contact with convex portions of the container, minimizing wear and dust generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotation portion made of urethane is used to abut against the container side surface for swing suppression, then the lateral swing of the container is suppressed, but wear occurs in the rotation portion causing dust generation
Solution Approach 1:
The invention extracts the harmful convex portion from the contact interface by forming a concave groove in the rotation portion that corresponds to the convex portion's position. This allows the rotation portion to rotate without contacting the convex portion, eliminating wear and dust generation while maintaining swing suppression functionality through contact with the smoother container surface.
Solution Approach 2:
Instead of making the container surface smooth to prevent wear, the invention inverts the approach by modifying the rotation portion to have a concave groove that actively avoids the convex portion. This reverses the problem-solving direction from modifying the container to modifying the suppression mechanism itself.
2Ease of operation
If the rotation portion contacts the container side surface to suppress lateral swing, then swing control is achieved, but the contact causes wear and dust generation
Solution Approach 1:
The harmful convex portion is extracted from the contact interface by forming a corresponding concave groove in the rotation portion. This allows the mechanism to maintain swing control capability through contact with the container's smoother surface areas while eliminating wear and dust generation from contact with the convex portion.
Solution Approach 2:
The concave groove is strategically positioned in the region corresponding to the convex portion, creating a local quality difference in the rotation portion. This allows different regions of the rotation portion to have different functions: the grooved region avoids contact to prevent wear, while other regions maintain contact for swing suppression.
3Reliability
If a rotation portion is used to abut against the container for swing suppression, then lateral swing is controlled, but contact with convex portions causes localized wear
Solution Approach 1:
The invention extracts the wear-causing convex portion from the contact interface by forming a concave groove in the rotation portion at the corresponding location. This allows the rotation portion to maintain stable swing suppression through contact with the container's smoother surface while eliminating localized wear at the convex portion contact point.
Solution Approach 2:
The concave groove creates a local quality modification in the rotation portion, concentrating the wear-resistant property in the region that would otherwise contact the convex portion. This localized modification preserves overall swing suppression stability while protecting against localized wear.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively suppresses lateral swing and reduces wear and dust by ensuring the abutment roller does not contact convex portions of the container, thereby maintaining operational efficiency and cleanliness.

AI summary
A transport vehicle that transports a container while being suspended includes a lateral swing suppression device configured to abut against an outer side surface of the container that is suspended and held, and suppress a lateral swing of the container. The lateral swing suppression device includes an abutment roller configured to rotatably abut against the outer side surface of the container. A concave groove extending continuously over an entire periphery of an outer peripheral surface of the abutment roller is formed in a region corresponding to a convex portion of the container.
