Three-Wire Chafing Stand Structure for Stable Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire chafing stands are complex and costly to manufacture, with limited nesting capability, leading to high transportation and storage costs, which hampers their ability to compete in large geographical areas.
Innovation Solution
A wire chafing stand design featuring a closed loop formed from one wire with two identical wires bent symmetrically, attached at a midpoint and connected to the loop with a minimal number of weld points, providing stability and a fuel receptacle with reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire chafing stands use traditional multi-wire construction with multiple weld points, then structural stability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines multiple wire functions into three primary wires: one wire forms the upper rim, one wire forms the lower rim, and one wire serves as the leg connecting both rims. This merging reduces the number of separate wire components and weld points while maintaining structural integrity and stability of the chafing stand.
2Reliability
If wire chafing stands use traditional construction methods, then structural integrity is maintained, but material usage and production cost increase
Solution Approach 1:
The patent extracts and eliminates unnecessary wires and weld points from the traditional construction. By using only three wires with minimal weld points, the design removes excess material while preserving the essential structural integrity needed to support the chafing dish and fuel source.
3Device complexity
If wire chafing stands are designed with limited nesting capability, then structural design is simplified, but transportation and storage costs increase
Solution Approach 1:
The patent designs the chafing stand with nesting capability where the leg structure allows one stand to be placed inside another. The upper rim and lower rim are positioned and dimensioned to enable efficient vertical stacking, reducing the space required for storage and transportation of multiple stands.

AI summary
A chafer wire stand of three lengths of wire has one length of wire as an upper loop and the other two substantially identical to each other, as well as being mirror images of themselves. These two lengths of wire are laid out perpendicular to each other, and each end thereof attaches to the upper loop. These two lengths are connected to the upper loop, then have a vertical drop to the bottom followed by a section acutely angled back upwards, then an acute angled drop to the bottom again in a second vertical section. Then a right angle connection from the vertical section to a horizontal section forms the outline or exterior of a receptacle for a heat source. This half wire section is repeated three more times (two wires, two half wire sections each) forming an economical wire chafing stand which only requires four or five weld points.
