Upper Rail Attachment Groove for Stacker Crane Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing transport systems using stacker cranes require accurate alignment and construction of upper rails relative to lower rails, which is currently difficult to achieve efficiently.
Innovation Solution
A transport system with a lower rail for the stacker crane to travel on, an upper rail for guidance, and a beam part spanning between storage shelves, where the upper rail is supported by the beam part using an attachment part with a groove for a fastening member, allowing for easy adjustment and securement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the upper rail is mounted using conventional rigid fixation methods, then the structural stability is improved, but the alignment precision and ease of construction deteriorate
Solution Approach 1:
The attachment part is designed with a groove portion that allows the fastening member to move in the longitudinal direction of the beam part while maintaining engagement. This dynamic adjustment capability enables the upper rail to be precisely aligned with the lower rail during construction, while the groove structure maintains structural stability once positioned. The fastening member can slide along the groove to achieve optimal alignment, then be secured in place to maintain both precision and stability.
2Strength
If the upper rail is constructed with rigid fixation, then the structural strength is improved, but the ease of construction and adjustment deteriorates
Solution Approach 1:
The attachment system is divided into separate components: the attachment part with the groove portion, the fastening member, and the beam part. This segmentation allows for modular assembly where the upper rail can be independently positioned and adjusted relative to the beam part. The groove portion acts as a guiding element that simplifies the alignment process, while the fastening member provides the necessary structural strength when engaged with the groove. This segmented design makes the construction process more straightforward compared to rigid monolithic fixation methods.
3Reliability
If conventional fixation methods are used for the upper rail, then the reliability is improved, but the ease of operation during construction deteriorates
Solution Approach 1:
The groove portion in the attachment part serves as an intermediary element between the fastening member and the beam part. This groove structure facilitates easy operation during construction by providing a guiding path for the fastening member, allowing for simple alignment and adjustment of the upper rail. The groove acts as a mediator that translates the positioning action into reliable engagement, maintaining reliability while significantly improving ease of operation during the construction process.

AI summary
It is possible to easily carry out construction of an upper rail. A transport system is configured to include: a lower rail that allows a transport device to travel thereon; an upper rail that guides the transport device; a beam part that is spanned between a pair of storage shelves installed on corresponding opposite sides of the lower rail; and an attachment part, the beam part having a groove portion that allows a fastening member to be engaged therewith and that extends in a longitudinal direction, the upper rail being supported by the beam part when the attachment part is fastened and secured to the beam part with the fastening member.
