Collapsible Fabric Grill Structure for Portable High-Heat Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional grills are large, bulky, and cumbersome, making them difficult to transport and store, while portable alternatives often sacrifice size for portability and still lack ease of use and storage.
Innovation Solution
A collapsible, high-temperature, heat and flame-resistant fabric cooking grill with a metallic grill grate and charcoal basket, featuring a collapsible frame and ventilation holes, designed for easy assembly and disassembly, using high-temperature materials like silicate fiber or fiberglass with silicone coating, and adaptable for use with propane fuel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional grills are made from porcelain-enameled or ceramic materials or aluminum, steel or other metallic materials to meet structural and environmental demands, then the grill can support fuel source and food and resist flames and heat, but the grill becomes large, bulky, heavy and difficult to transport
Solution Approach 1:
The patent applies flexible heat-resistant fabric (silicone-coated fiberglass or silicate fiber) to replace traditional rigid metallic or ceramic grill construction. This flexible fabric allows the grill to be rolled up or folded for compact storage and easy transport while maintaining high-temperature and flame resistance during operation
Solution Approach 2:
The patent uses composite materials combining fiberglass or silicate fiber with silicone coating to create a fabric that simultaneously provides structural integrity, heat resistance, and flexibility. This composite approach enables the grill to be both heat-resistant and portable
2Weight of moving object
If portable grills are made smaller to improve portability, then the grill becomes easier to transport, but the grill sacrifices size and may become cumbersome for actual grilling use
Solution Approach 1:
The patent employs a dynamic design where the flexible fabric body can be rolled up or folded into a compact form for portability, then expanded into a full-size functional grill when needed. The fabric maintains structural rigidity during grilling operations while allowing easy collapse for storage
3Weight of moving object
If the grill is made from collapsible fabric material to improve portability and storage, then the grill becomes lightweight and easy to transport, but the grill must quickly cool down after use to allow safe disassembly and storage
Solution Approach 1:
The thin flexible fabric construction inherently provides faster heat dissipation compared to thick metallic walls, allowing the grill to cool down more quickly after use. This enables safer and faster disassembly and storage while maintaining portability benefits
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 grill is lightweight, easy to store and transport, cools quickly, and provides a compact form factor, while maintaining high-temperature cooking capabilities and ease of use with a portable propane fuel source.
Implementation Method 1
high-temperature, heat and flame resistant, collapsible, portable, fabric cooking grill
Implementation Method 2
heat and flame resistant fabric
Implementation Method 3
the fabric may incorporate a reflective inner coating, such as, for example, an aluminum coating
Implementation Method 4
The structure of the grill is provided, at least in part, by a collapsible frame structure made from heat resistant structural material
Implementation Method 5
a suspended charcoal basket... formed from a metal mesh or netting, which enables the basket to support the charcoal, allow the ash to fall through the basket

AI summary
A portable grill includes: a cooking grate; a collapsible body surrounding the sides and bottom of the cooking grate and collapsible mesh basket when the grill is configured for cooking; a collapsible frame supporting the position of the body, cooking grate, and the mesh basket when the grill is configured for cooking; and a removable collapsible lid adapted to cooperate with the body to completely surround the cooking grate and mesh basket when the grill is configured for cooking, wherein the collapsible body and collapsible lid are formed primarily from a flexible high temperature resistant material.
