Transport Vehicle Column Through Holes Spatial Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In article transport facilities with multiple levels, interference between support columns and transport vehicles limits the proximity of travel routes, reducing spatial efficiency and requiring wasted space to avoid collisions.
Innovation Solution
A support frame comprising columns and beams with column through holes that allow columns to extend through and protrude above the travel surface, enabling columns to be positioned both at the edge and center of the travel floor without overlapping vehicle paths, ensuring the rigidity of the travel floors while allowing close placement of travel routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If columns are positioned to avoid interfering with transport vehicles, then safety is improved, but travel routes must be spaced farther apart reducing spatial efficiency
Solution Approach 1:
The patent applies dimensionality change by having columns extend through the travel floor in the vertical dimension rather than being confined to a single plane. Columns protrude above the travel surface, allowing travel routes to be positioned in the horizontal plane without interference, thus resolving the contradiction between safety and spatial efficiency
Solution Approach 2:
The support structure is segmented into multiple columns distributed across the travel floor, with each column independently positioned to avoid interfering with vehicle paths. This segmentation allows optimized placement that maintains both safety and spatial efficiency
2Area of stationary object
If columns are positioned close to travel routes to maximize space usage, then spatial efficiency is improved, but interference with transport vehicles occurs reducing safety
Solution Approach 1:
By extending columns vertically through the travel floor and allowing them to protrude above the surface, the patent moves the support function to a different dimension. This allows horizontal space to be fully utilized for vehicle travel without compromising safety, as columns occupy the vertical dimension rather than horizontal space
3Reliability
If columns are positioned only at outer edges of travel floors, then vehicle interference is avoided, but structural rigidity of travel floors is reduced
Solution Approach 1:
The patent enables columns to be positioned in the central region of travel floors by extending them vertically through the floor structure. This vertical positioning allows columns to provide structural support and rigidity without interfering with vehicle travel in the horizontal plane, thus resolving the contradiction between interference avoidance and structural strength
Solution Approach 2:
Columns are strategically positioned at specific locations where they provide maximum structural benefit without interfering with vehicle paths. The local quality of support is enhanced by allowing columns to protrude above the travel surface, providing targeted reinforcement where needed

AI summary
An article transport facility includes a transport vehicle configured to travel on a travel surface on each of a plurality of travel floors. The transport vehicle is configured to travel straight and to change directions by executing turning movement to turning about an axis in the up-down direction on a spot. Columns extend through the travel floors in the up-down direction and protrude upward of the travel surface. Each travel floor has column through holes that are for the columns to extend through. The column through holes do not overlap a first straight path, a second straight path, and a turning path as viewed in the up-down direction, and overlap at least either a first tangent line or a second tangent line.
