Shuttle Warehouse Guide Rail Weld Stud Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shuttle warehouses experience noise and vibration issues due to the impact of distribution vehicle wheels on fastening points, which can damage sensitive goods and disrupt operations.
Innovation Solution
The use of welding studs to fix running rail segments to the frame, welded at the rear of the running surface, eliminates unevenness and reduces noise generation by ensuring a smooth running surface, and allows for easy segment replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fastening elements (e.g., press-in threaded bolts) are used to fix guide rail segments to the frame, then the segments can be securely attached, but the fastening elements create unevenness on the running surface that generates noise and vibration when wheels drive over them
Solution Approach 1:
The harmful fastening elements are extracted from the running surface area. Instead of having fastening elements protrude into or on the running surface, the patent uses welding studs that are welded to the rear side of the guide rail segments, completely removing the source of noise and vibration from the wheel path while maintaining secure attachment
Solution Approach 2:
The attachment method transitions from a two-dimensional surface mounting (fastening elements on or in the running surface) to a three-dimensional solution where welding studs are attached to the rear face of the segments, moving the attachment point to a different spatial dimension that does not interfere with wheel movement
2Ease of manufacture
If mounting holes are created in guide rail segments to attach fastening elements, then segments can be fixed to the frame, but the mounting process becomes more complex and requires additional holes in the structure
Solution Approach 1:
The mechanical fastening system requiring holes and fastening elements is replaced with a welding process. Welding studs are welded directly to the rear side of the guide rail segments, eliminating the need for mounting holes and simplifying the attachment process while maintaining structural integrity
Solution Approach 2:
The attachment method changes from mechanical (holes and fasteners) to thermal (welding). This parameter change in the joining process eliminates the need for holes through the segments and simplifies the overall mounting procedure
