Sheet-Metal Track Assembly for Faster Storage Grid Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage systems require complex and time-consuming assembly of grid framework structures, necessitating numerous supports and bracing, which occupy space, limit positioning options, and increase costs, while the track systems require multiple rail sections complicating assembly.
Innovation Solution
A track system using sheet metal blanks formed into U-shaped cross-sections with integrated or mounted tracks, allowing for simplified assembly and reduced material usage, featuring snap-fit connections and reduced parts, enhancing structural integrity and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional grid framework structures are used with multiple supports and bracing, then structural stability is improved, but assembly complexity and time increase
Solution Approach 1:
The patent combines the track support and the track into a single integrated U-shaped component. The track is formed as an integral part of the support structure, eliminating the need for separate bracing elements and reducing the number of parts that need to be assembled. This integration maintains structural stability while significantly simplifying assembly procedures.
Solution Approach 2:
The U-shaped track support serves multiple functions simultaneously: it provides structural support, guides the load handling device, and acts as the track itself. This multi-functionality eliminates the need for separate bracing components, reducing assembly complexity while maintaining the required structural stability.
2Area of stationary object
If multiple rail sections are used to form tracks, then track coverage is improved, but assembly time and complexity increase
Solution Approach 1:
The track system is divided into modular U-shaped support sections that can be independently manufactured and then assembled. Each section contains integrated track features, allowing for easy connection between segments while maintaining continuous track coverage. This segmentation enables rapid assembly compared to traditional multi-section rail systems.
3Strength
If numerous supports and bracing are used, then structural integrity is improved, but space utilization decreases
Solution Approach 1:
By merging the support structure and track into a single U-shaped component, the patent eliminates the need for additional bracing elements that would occupy space. The integrated design provides the necessary structural integrity while maximizing the available storage space within the grid framework.
4Strength
If traditional track assembly methods are used, then track strength is improved, but manufacturing cost increases
Solution Approach 1:
The integration of track and support into a single U-shaped component reduces the total number of parts that need to be manufactured, stored, and assembled. This simplification lowers manufacturing costs while the unified structure maintains or improves track strength through optimized load distribution.
