Portable Cooking Stove With Adjustable Legs for Uneven Ground
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable cooking stoves lack adjustable height and stability on uneven surfaces, making them less versatile and prone to spills, and often lack convenient carrying options.
Innovation Solution
A portable cooking stove with telescoping legs that can be individually adjusted for height and a compact design with carrying handles and a shoulder strap, allowing for stable operation on uneven surfaces and easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stove is designed with fixed legs, then the structure is simple, but the stove cannot be adjusted for uneven surfaces and is prone to spills
Solution Approach 1:
The patent applies the dynamics principle by making the legs adjustable in length rather than fixed. Each leg can be extended or retracted to different positions, allowing the stove to adapt to uneven ground surfaces. This dynamic adjustment capability resolves the contradiction by providing versatility without requiring a completely complex restructuring of the leg mechanism.
Solution Approach 2:
The legs are segmented into multiple sections that can be extended or retracted independently. This segmentation allows each leg to be adjusted individually to compensate for uneven surfaces, while maintaining a relatively simple overall structure. The segmented design enables adaptability without proportionally increasing device complexity.
2Ease of operation
If the stove includes carrying handles and shoulder strap, then portability is improved, but the device complexity increases
Solution Approach 1:
The base structure serves multiple functions: it supports the burners, provides mounting points for the legs, and includes integrated carrying handles. The shoulder strap attaches to the base structure, which already serves as the primary support framework. This multi-functionality approach improves portability without adding separate dedicated structures, thereby minimizing the increase in device complexity.
3Volume of moving object
If the legs are made telescoping for compact storage, then portability is improved, but the manufacturing complexity increases
Solution Approach 1:
The telescoping legs utilize a simple extension and retraction mechanism that allows the legs to be compact for storage yet extended for use. This dynamic design reduces the storage volume significantly while maintaining ease of manufacture through straightforward mechanical telescoping joints rather than complex assembly mechanisms.

AI summary
A portable cooking stove is disclosed. The cooking stove includes a base structure. At least one burner is positioned within the base structure. A burner plate is positioned above the burner and also above the base structure. When the stove is in use, a cooking surface may be placed on top of the burner plate. Multiple legs are connected to the base structure. The legs can be positioned in an extended configuration in which the base structure is positioned at a certain height above a ground surface. When the legs are positioned in the extended configuration, the height at which the base structure (and therefore the burner plate and any cooking surface that is placed on the burner plate) is positioned above the ground surface is adjustable without removing the legs from the base structure.
