Collapsible Leg Assembly for Cooking Grill Loading and Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking grills face challenges in being easily loaded and unloaded from raised platforms, such as vehicle storage compartments, due to their size and weight, limiting their mobility and ease of use.
Innovation Solution
A cooking grill design featuring a collapsible leg assembly and a lift bar mechanism that allows the grill to transition between deployed and collapsed positions, enabling efficient loading and unloading by pivoting and lifting the grill for safe maneuvering on elevated surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cooking grill is designed with a larger size for enhanced cooking capacity, then the cooking performance is improved, but the ease of loading and unloading from raised platforms deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the leg assembly collapsible and the lift bar movable. The legs can transition between deployed and collapsed positions, allowing the grill to be compact for loading and stable for cooking. The lift bar can be positioned at different locations on the cooking chamber, enabling flexible loading configurations. This dynamic adaptability resolves the contradiction between large cooking capacity and ease of loading from raised platforms.
2Volume of moving object
If the cooking grill is designed with a larger size for enhanced cooking capacity, then the cooking performance is improved, but the mobility deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the support structure into collapsible leg assemblies that can be independently folded. The leg assembly includes multiple segments that can be collapsed into a compact configuration for transport and deployed for use. This segmentation allows the grill to maintain large cooking capacity while improving mobility and adaptability for different storage and transport scenarios.
3Ease of operation
If the leg assembly is made collapsible for easier loading, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent applies the nested doll principle by collapsing the leg assembly into a compact configuration where the leg segments are nested within or adjacent to the cooking chamber. The collapsed leg assembly occupies minimal space and integrates smoothly with the overall grill structure. This nesting approach enables easy loading without significantly increasing structural complexity, as the collapsible mechanism uses straightforward hinged connections and compact folding geometry.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design facilitates easy and safe transportation and maneuvering of a larger cooking grill with enhanced cooking capacity, allowing for efficient loading and unloading from raised platforms without compromising size or cooking performance.
Implementation Method 1
a lift bar coupled to the cooking chamber at a first connection and a second connection... the lift bar is configured to pivot relative to the cooking chamber about the first connection... lifting the cooking chamber upward

AI summary
An example cooking grill comprises a cooking chamber, and a leg coupled to the cooking chamber. The leg is to transition between: a deployed position in which the leg extends outward from the cooking chamber; and a collapsed position in which the leg is received within a channel on a bottom side of the cooking chamber.
