Solution Overview

Problem

Existing gel-type fuels for cooking and food warming in high-end kitchens face challenges with ventilation safety, temperature control, combustion rate, portability, residual taste, and cost, particularly in using ethanol-based fuels which require a formulation that balances efficiency, cleanliness, and adaptability for various applications.

Innovation Solution

A formulation using ethanol from renewable sources, water, and Glyoxal as a cellulose-based gelling agent, allowing for adjustments to create three distinct forms: a classic gel for food prep, a pourable fuel for refilling, and an igniter, with optimized viscosity and pH control to ensure safe, efficient, and odorless performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If ethanol is used as base fuel, then ventilation safety is improved (cleaner combustion), but combustion rate and energy density are reduced

Engineering Contradiction:
Improveventilation safetyVSAvoidcombustion rate
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent modifies the physical state and concentration parameters of ethanol by formulating it as a gel with controlled viscosity and water content. This changes the combustion characteristics to achieve both clean burning and appropriate combustion rate for food warming applications.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite fuel system combining ethanol with water and gelating agents. This composite formulation maintains the clean combustion benefits of ethanol while the added components regulate burn rate and provide proper energy density for sustained food warming.

Inventive Principle:
Principle #40Composite materials

2Temperature

If gel formulation is used, then temperature control is improved, but portability and flowability are reduced

Engineering Contradiction:
Improvetemperature controlVSAvoidportability
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The patent creates a dynamic fuel system where the gel formulation can be adjusted between more viscous states for temperature control and less viscous states for portability. The gelating agents and water content can be modified to achieve the desired balance between thermal performance and ease of handling.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple formulations are created, then adaptability is improved, but manufacturing complexity is increased

Engineering Contradiction:
ImproveadaptabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the fuel formulation into distinct components (ethanol, water, gelating agents) that can be independently selected and combined. This allows different formulations for different applications (food warming, igniter, refill) using the same basic components, reducing overall manufacturing complexity while maintaining adaptability.

Inventive Principle:
Principle #1Segmentation

AI summary

An improved gel-type fuel comprising three essential ingredients, namely, ethanol from renewable sources e.g. sugar cane, sugar beet, etc. water and a cellulose based gelling agent also from renewable sources. By varying the viscosity of the fuel with differing percentage of said gelling agent, three distinctly functioning fuels are produced as a gel, a pourable refilling fuel and a less viscous fire lighting fuel.
