Campfire Grill Height Adjustment for Portable Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current campfire grills have stationary grates, making it difficult to control food temperature during cooking, and are often bulky, heavy, and hard to transport.
Innovation Solution
A freestanding campfire grill with an adjustable height grate, featuring a base frame, transverse stabilizers, a support column, a height adjustment assembly, and a cooking platform, allowing for temperature control and improved portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the grate is made stationary above the fire, then the grill structure is simple and stable, but temperature control during cooking becomes difficult
Solution Approach 1:
The patent applies the dynamics principle by making the grate height adjustable rather than fixed. The support column allows the grate to be positioned at different heights above the fire, enabling temperature control through vertical adjustment. This transforms the stationary grate into a dynamic, adjustable component that adapts to different cooking temperature requirements.
2Weight of moving object
If the grill is designed to be portable, then it becomes easier to transport, but the structural stability may be compromised
Solution Approach 1:
The patent applies segmentation by dividing the grill into separate modular components: a base frame, a detachable support column, and a grate assembly. This allows the grill to be disassembled for easy transport and reassembled for stable cooking. The segmented design reduces overall weight and facilitates carrying while maintaining structural integrity when assembled.
3Ease of operation
If the support column is made adjustable in height, then temperature control is improved, but the device complexity increases
Solution Approach 1:
The support column implements dynamics through its adjustable height mechanism, allowing the grate to be raised or lowered to control the distance from the fire and thus the cooking temperature. The column transitions from a static support to a dynamic, variable-height component that responds to cooking temperature needs.
Solution Approach 2:
The patent applies parameter changes by varying the height parameter of the support column to achieve different cooking temperatures. By changing this single geometric parameter, the system controls the thermal environment without requiring complex temperature regulation mechanisms.
4Stability of the object's composition
If transverse stabilizers are added to improve stability on uneven ground, then the grill becomes more stable, but the device complexity and assembly difficulty increase
Solution Approach 1:
The transverse stabilizers are designed as detachable segments that can be independently attached to the base frame. This segmentation allows users to add or remove stabilizers as needed and simplifies the assembly process, as each stabilizer can be attached separately rather than requiring complex integrated mounting.

AI summary
A portable grill includes a base frame, a set of transverse stabilizers, a support column, a height adjustment assembly, and a cooking platform. The base frame and the transverse stabilizers are configured to rest on a supporting surface. The support column extends upwardly from the base frame. The height adjustment assembly moves up and down the support column and can be selectively fixed in multiple positions along the support column. The cooking platform is coupled to said height adjustment assembly and oriented such that a center of the cooking platform is disposed over a region of the supporting surface between an adjacent pair of the transverse stabilizers.
