A disposable grill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable grills are difficult to dispose of properly due to their flammability and potential for causing fires, and existing solutions either lack safety or environmental friendliness.
Innovation Solution
A disposable grill with a base tray and sidewalls made from biodegradable materials, incorporating a fireproof thermal insulating insert to protect against high temperatures and prevent damage to the environment, along with a biodegradable grate for quick decomposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base tray is made from biodegradable material, then the environmental friendliness and decomposition speed are improved, but the fire safety and temperature resistance deteriorate
Solution Approach 1:
The base tray is divided into multiple layers: an outer biodegradable layer for environmental friendliness and an inner fireproof layer for safety. This segmentation allows each layer to perform its specific function without compromising the other.
Solution Approach 2:
The base tray uses a composite structure combining biodegradable material (such as纸板 or plant fibers) with fireproof material (such as ceramic coating or fire-resistant treatment). This composite approach achieves both environmental sustainability and fire safety simultaneously.
2Duration of action of stationary object
If the base tray is made from biodegradable material, then the decomposition time is reduced, but the temperature resistance during grilling deteriorates
Solution Approach 1:
The base tray is segmented into an outer biodegradable layer that decomposes quickly and an inner fireproof layer that withstands high temperatures during grilling, allowing each layer to perform its specific function optimally.
Solution Approach 2:
Different parts of the base tray have different material properties: the outer layer is made of biodegradable material for quick decomposition, while the inner layer is treated with fireproof coating or made from heat-resistant material to withstand grilling temperatures.
3Object-affected harmful factors
If a thermal insulating insert is added to protect from heat, then the safety and heat protection are improved, but the device complexity increases
Solution Approach 1:
The thermal insulating function is merged into the base tray structure itself through fireproof treatment or coating, rather than adding a separate insert. This integration maintains safety while minimizing structural complexity.
Solution Approach 2:
The base tray uses composite material construction where fireproof material or coating is combined with biodegradable material, providing both thermal insulation and environmental friendliness in a single integrated component.

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 solution provides a safer and more environmentally friendly disposal option by ensuring the grill decomposes quickly and reduces the risk of fires, while protecting the user and surrounding surfaces from heat damage.
Implementation Method 1
the disposable grill further comprises at least one fireproof thermal insulating insert arranged in the base tray
Implementation Method 2
the base tray and the one or more sidewalls are formed by a biodegradable material
