Folding Stove Stand Structure for Heat-Safe Surface Elevation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable stoves often risk heat damage when placed on non-heatproof surfaces due to their hot components, as they lack a suitable stand to elevate and protect the surface from heat transfer.
Innovation Solution
A foldable stand designed for portable stoves that elevates the stove above non-heatproof surfaces, featuring legs with hinges and feet that include standoffs and interference arms to prevent lateral movement and minimize heat transfer, and can be stored inside the stove for transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the portable stove is placed directly on a non-heatproof surface, then the stove is stable and easy to use, but the surface suffers heat damage
Solution Approach 1:
The stand is divided into multiple functional components: central intersection, legs with inner links, outer links connected by hinges, feet with standoffs and interference arms. This segmentation allows each component to perform its specific function while maintaining overall stability and heat protection capability.
Solution Approach 2:
The stand is designed to fold into a compact configuration that nests within the portable stove body during transportation or storage. The legs and feet collapse inward, allowing the stand to be stored inside the stove without requiring additional carrying space.
2Adaptability or versatility
If the stand is designed with fixed legs, then the stove is stable on the surface, but the stand cannot be stored inside the stove for portability
Solution Approach 1:
The stand transitions from a static fixed-structure design to a dynamic folding mechanism. The outer links are connected to inner links by hinges, allowing the legs to pivot between extended (stable) and retracted (stored) positions. This dynamic design enables the stand to adapt between providing stability during use and compactness during storage.
3Object-affected harmful factors
If the stand elevates the stove high above the surface, then heat transfer is minimized, but the stand width increases making it harder to store
Solution Approach 1:
The folding leg mechanism allows the stand to achieve maximum elevation height when deployed for heat protection, then collapse to minimum volume for storage. The hinged outer links enable the legs to pivot from an extended position (providing height) to a retracted position (minimizing storage volume).

AI summary
A stand is provided for elevating a portable stove above a surface. The stand includes a central intersection and a plurality of legs. Each leg includes an inner link extending radially outward from the central intersection, and an outer link connected to the inner link by a hinge. The outer link is thus movable to a position extending radially outward from the inner link. Each leg also includes a foot coupled to, and extending transverse to, the outer link. Each foot includes a standoff extending transverse from the outer link in a first direction, and an interference arm extending transverse from the outer link in a second direction opposite the first direction.
