Drying Pallet Corner Welding Gap Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for drying objects like bricks and concrete suffer from instability due to unreliable spot welding connections, which result in gaps and reduced quality, and are costly to produce.
Innovation Solution
The support surfaces in the corner regions of the device are connected using solder welding after forming a depression, ensuring a secure connection without protrusion beyond the pallet surface, and reinforced with embossed indentations to prevent stress during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spot welding is used to connect folded sheet metal surfaces, then connection is achieved, but process reliability is reduced due to gaps and tolerance issues
Solution Approach 1:
The patent applies preliminary action by forming recesses in the sheet metal surfaces before welding. These recesses are created in advance to accommodate the weld material and ensure proper alignment, preventing gaps and tolerance issues that would otherwise compromise weld quality and connection reliability.
Solution Approach 2:
The recesses act as intermediaries between the two sheet metal surfaces to be welded. By providing a prepared receptacle for the weld material, the recesses mediate the connection process, ensuring that tolerances and minor misalignments do not result in defective welds, thereby improving both manufacturing precision and connection reliability.
2Strength
If sheet metal surfaces are folded and connected with spot welds, then structure is formed, but connection strength is reduced due to gaps
Solution Approach 1:
The recesses are formed in advance before the welding process, creating a prepared structure that ensures proper weld material placement. This preliminary preparation eliminates gaps and ensures consistent contact between surfaces, leading to stronger and more reliable connections while improving process reliability.
3Ease of manufacture
If conventional welding methods are used, then connection is achieved, but production costs increase
Solution Approach 1:
By forming recesses as a preliminary step, the patent enables the use of simpler, more cost-effective welding processes that can achieve reliable connections without requiring complex positioning or rework. The recesses ensure proper weld material flow and distribution, reducing manufacturing costs while maintaining high connection quality and reliability.

AI summary
The device has a storage surface (1) including upper and lower longitudinal and transverse edges (2, 4), where side walls (3) of the edges (2) point downwards. Bearing surfaces (5) of the edges (4) point under the storage surface, where the bearing surfaces are aligned parallel to the storage surfaces. Two adjacent side walls and two adjacent bearing surfaces form an edge area (6). The bearing surfaces are joined to each other at an obtuse angle in the edge area, where the bearing surfaces are connected with a soldering weld that is formed in an area of a recess (7).
