Flammable Disposable Grill Structure for Fast Decomposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable grills made from traditional materials are difficult to dispose of and take a long time to decompose, and alternatives that use biodegradable materials with minerals are expensive and slow to decompose.
Innovation Solution
A disposable grill made from flammable materials with an autoignition temperature between 100° C and 650° C, where both the base tray and grate are formed as monolithic pieces using organic materials, reducing the need for a separate heat source and allowing the grill to self-destruct after use, thus minimizing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If disposable grills are made from traditional materials (thin aluminum plates with metal grate), then the grill structure is strong and durable during use, but the grill is difficult to dispose of and takes a very long time to decompose
Solution Approach 1:
The patent changes the material parameters from traditional metal and plastic to flammable organic materials (wood, bamboo, corncobs, coconut shell, straw, seeds, grains, corn, sugarcane, elephant grass, nutshell, leaves, plants, paper, or cardboard). This parameter change transforms the decomposition characteristics while maintaining structural integrity during use through controlled material selection and design
Solution Approach 2:
The patent implements a truly disposable design where the entire grill structure is made from inexpensive, biodegradable flammable materials that can be safely discarded after use. The grill is designed to burn completely during or after use, leaving minimal residue, eliminating the need for long-term disposal infrastructure
2Reliability
If disposable grills are made from biodegradable materials mixed with minerals or stone dust, then the grill is fireproof and does not burn during use, but the grill is expensive and takes a relatively long time to decompose
Solution Approach 1:
The patent converts the previously harmful characteristic of flammability into a beneficial feature. By making the grill structure itself flammable, it eliminates the need for expensive mineral additives and creates a self-destructing grill that burns completely after use, providing both fireproof performance during controlled burning and rapid decomposition afterward
Solution Approach 2:
The patent extracts and removes the expensive mineral or stone dust additives from the material composition. By taking out these costly components and relying solely on natural flammable organic materials, the manufacturing cost is significantly reduced while maintaining the desired fireproof and biodegradable characteristics
3Temperature
If the base tray and grate means are made from flammable material with low autoignition temperature, then the grill catches fire quickly and contributes to heat generation, but the cooking time is too short because the grill burns out too quickly
Solution Approach 1:
The patent optimizes the autoignition temperature parameter of the flammable material to fall within the specific range of 100°C to 650°C. This parameter change balances the competing requirements: low enough to ensure quick ignition and heat generation, but high enough to maintain structural integrity and provide sufficient cooking time. The patent further specifies a preferred range of 200°C to 550°C and a most preferred range of 250°C to 500°C for optimal performance
4Strength
If the base tray and grate means are made from flammable material with high autoignition temperature, then the grill maintains structural integrity for longer, but the grill might not catch fire or will take so long to ignite that its contribution to heat generation is severely reduced
Solution Approach 1:
The patent establishes an optimal parameter range for autoignition temperature (100°C to 650°C, preferably 200°C to 550°C, most preferred 250°C to 500°C) that balances structural integrity with heat generation efficiency. This parameter optimization ensures the grill catches fire within a reasonable time frame while maintaining sufficient structural strength during the grilling process
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 efficiently generates heat for cooking, reduces waste, and decomposes quickly, minimizing environmental impact while being cost-effective and environmentally friendly.
Implementation Method 1
the autoignition temperature of said flammable material is between 100° C. and 650° C., preferably between 200° C. and 550° C. and most preferred between 250° C. and 500° C.
Implementation Method 2
the disposable grill hereby will burn during or at least in continuation of its use thereby leaving just a small amount of material behind
