Foldable Barbecue Grill with Hinged Segmentation for Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barbecue grills are bulky, difficult to move, and have complex structures that make them inconvenient and time-consuming to install and fold.
Innovation Solution
A foldable barbecue grill design featuring symmetrically hinged cover and furnace plates with strategically positioned hinge pins and stop blocks, allowing for easy rotation and folding, and a self-supportive structure that simplifies installation and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional barbecue grills are made bulky and non-disassemblable, then structural stability is improved, but portability deteriorates
Solution Approach 1:
The barbecue grill is divided into multiple detachable components including a grill body, ash receiving chamber, and cover that can be separated and reassembled. This segmentation allows the grill to be disassembled for easy portability while maintaining structural stability when assembled, directly resolving the contradiction between stability and portability.
2Length of moving object
If foldable barbecue grills include complex structures with multiple hinged components, then portability is improved, but installation complexity deteriorates
Solution Approach 1:
The patent extracts and eliminates complex fastening mechanisms, multiple hinged sheets, and interlocking buckle structures from conventional foldable grills. The simplified design uses a direct assembly approach where components are positioned and secured without requiring unfolding of multiple sheets or interlocking mechanisms, thereby reducing installation complexity while maintaining portability.
3Length of moving object
If foldable barbecue grills include multiple hinged sheets and buckle structures, then portability is improved, but installation time deteriorates
Solution Approach 1:
The grill components are designed to be pre-positioned and pre-aligned during manufacturing, allowing for rapid assembly during installation. The ash receiving chamber, grill body, and cover are designed with alignment features that enable quick connection without requiring time-consuming unfolding of hinged sheets or manual interlocking of buckles, thus reducing installation time while preserving portability.

AI summary
A barbecue grill, including a first cover plate, a first furnace wall, a second furnace wall, a second cover plate, and a hinge seat. The first cover plate includes first hinge members, and each first hinge member includes a first unfixed terminal. The first furnace wall includes second hinge members, and each second hinge member includes a second unfixed terminal. The second furnace wall includes third hinge members, and each third hinge member includes a third unfixed terminal. The second cover plate includes fourth hinge members, and each fourth hinge member includes a fourth unfixed terminal. The first hinge members are disposed on two sides of one end of the first cover plate, respectively, and the first hinge members are fixed on the hinge seat via a first hinged pin. The second hinge members are disposed on two sides of one end of the first furnace wall, respectively.
