Solution Overview

Problem

Disposable grills are difficult to dispose of properly due to their persistence in the environment and the risk of uncontrolled burning, which can damage surroundings or start fires.

Innovation Solution

A disposable grill made from biodegradable materials with a fireproof thermal insulating insert, designed to decompose quickly and protect against high temperatures, reducing the risk of damage and fire hazards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If the base tray is made from biodegradable material, then the grill decomposes quickly in nature, but the material is flammable and damaged by high temperatures

Engineering Contradiction:

Improvedecomposition timeVSAvoidfire resistance

Core Design Contradiction:

Duration of action of stationary objectVSReliability

Solution Approach 1:

The base tray is divided into two functional layers: an outer biodegradable material layer for environmental friendliness and rapid decomposition, and an inner fireproof thermal insulating insert for heat protection. This segmentation allows each layer to perform its specific function without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base tray combines biodegradable material with fireproof thermal insulating material to create a composite structure. This composite design integrates the advantages of both materials: the biodegradable outer layer ensures rapid decomposition, while the fireproof inner layer provides thermal protection during grilling.

Inventive Principle:

Principle #40Composite materials

2Reliability

If the base tray is made from thin aluminium plate, then the grill is durable and heat-resistant, but the grill persists in the environment and is difficult to dispose of

Engineering Contradiction:

Improveheat resistanceVSAvoiddecomposition time

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The material composition of the base tray is changed from metallic (aluminium) to a composite of organic/biodegradable materials and fireproof insulating materials. This parameter change transforms the grill from non-biodegradable to rapidly decomposing while maintaining thermal resistance through the insulating insert.

Inventive Principle:

Principle #35Parameter changes

3Duration of action of stationary object

If flammable material is used to ensure the grill burns out, then the grill decomposes quickly, but the burning is difficult to control and may start fires

Engineering Contradiction:

Improvedecomposition timeVSAvoidfire hazard

Core Design Contradiction:

Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The fireproof thermal insulating insert acts as an intermediary between the heat source and the biodegradable material. It controls the thermal energy transfer, allowing the biodegradable material to decompose safely without uncontrolled burning or fire hazards.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The potential harm of flammable biodegradable material is converted into a benefit by using the fireproof thermal insulating insert to control the decomposition process. The insert allows safe, controlled decomposition without the harmful uncontrolled burning that would otherwise occur.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
