Welding Alignment via Interlocking Recesses and Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal shelves with holding plates or baskets made of metal meshes suffer from offset misalignment and poor welding quality due to straight connection ends and raised welding tracks, resulting in aesthetic and safety issues.
Innovation Solution
A positioning structure featuring multiple recesses and protrusions on adjacent bodies, where the height of protrusions exceeds the depth of recesses, allowing for secure retention and high-frequency welding to prevent misalignment and improve appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If two adjacent holding plates or holding baskets are welded together with straight connection ends, then the welding process is simple, but offset misalignment occurs and welding raised tracks form causing poor quality and appearance
Solution Approach 1:
The connection end structure is segmented into multiple recesses and multiple protrusions that are distributed along the connection end. This segmentation allows for precise positioning and alignment during welding, preventing offset misalignment while maintaining a relatively simple overall structure.
Solution Approach 2:
The recesses and protrusions are pre-formed on the connection ends before welding takes place. This preliminary action ensures that when the holding plates or baskets are assembled, the protrusions fit into the recesses in predetermined positions, establishing accurate alignment before the welding process begins and preventing welding raised tracks.
2Manufacturing precision
If multiple recesses and protrusions are formed on adjacent bodies for positioning, then offset misalignment is prevented and welding quality improves, but the manufacturing process becomes more complex
Solution Approach 1:
The positioning function is merged into the connection end structure itself by integrating recesses and protrusions directly onto the holding plates or baskets. This eliminates the need for separate positioning devices or complex fixtures, as the positioning features are built-in and perform both positioning and structural connection functions simultaneously.
Solution Approach 2:
The recesses and protrusions are designed to automatically align and position the adjacent bodies during assembly without requiring external positioning devices or complex manufacturing processes. The protrusions naturally fit into the recesses, providing self-aligning positioning that simplifies the overall manufacturing process despite the added geometric complexity.

AI summary
A positioning structure of a frame welding assembly for a metal product, the metal product is a holding plate or a holding basket made of metal mesh and contains: multiple bodies, each of the multiple bodies is folded in a square shape and includes multiple raised faces and multiple slots which are stamped on a peripheral side of each body respectively. Two adjacent of the multiple bodies are connected together, and the two adjacent bodies have multiple recesses and multiple protrusions respectively formed on two connection sides thereof so that the multiple recesses retain with the multiple protrusions individually before welding the two adjacent bodies together.
