Wire Chafing Stand T-Welded Rim for Safe Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire chafing stands require additional manufacturing complexity and cost due to the need for 'offsets' to prevent wedging during nested storage, which also results in wire overhangs that can be hazardous.
Innovation Solution
The wire legs are welded to the rim at a 90-degree angle, forming a 'T' configuration, eliminating the need for offsets and preventing wire overhangs, thus allowing multiple stands to be nested without wedging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If offsets are added to wire legs to prevent wedging during nested storage, then nesting capability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent removes the unnecessary offsets from the wire leg design. By extracting this redundant feature, the manufacturing process is simplified while the T-welded intersection configuration inherently prevents wedging during nested storage without requiring additional offset formations.
Solution Approach 2:
Instead of adding offsets to prevent wedging, the patent inverts the approach by using a T-welded intersection configuration where the wire leg is welded perpendicular to the rim. This inverted design approach eliminates the need for offsets while achieving the same nesting prevention function.

3Ease of manufacture
If overlap weld is used to attach wire legs to rim, then manufacturing simplicity is maintained, but wire overhang is created causing safety hazards
Solution Approach 1:
Instead of using conventional overlap welding that causes wire overhang, the patent inverts the welding configuration to a T-welded intersection where the wire leg is welded perpendicular to the rim. This inverted approach eliminates the overhang hazard while maintaining manufacturing feasibility.
Solution Approach 2:
The patent converts the potential harm of wire overhang into a benefit by using the T-welded intersection configuration. The perpendicular welding arrangement ensures that the wire leg ends meet the rim surface without extending beyond it, transforming a safety hazard into a safe design feature.
4Object-affected harmful factors
If T welded intersection is used to attach wire legs to rim, then wire overhang is eliminated, but welding precision requirements increase
Solution Approach 1:
The patent applies preliminary action by positioning the wire leg perpendicular to the rim before welding begins. This pre-positioning ensures that the T-welded intersection is formed with proper alignment, eliminating wire overhang while maintaining achievable welding precision through proper setup and procedure.

AI summary
The wire chafing stand of the present invention comprises a rim configured in any desired geometry having longitudinal and lateral sides and a plurality of wire legs extending from the rim with at least one end of each wire leg or both being welded to the rim such that a T-welded intersection is substantially formed between the wire legs and at least the longitudinal sides of the rim in which the longitudinal axis of each such wire leg intersects the longitudinal axis of the rim to form an included angle of substantially 90°.
