Solution Overview

Problem

Rural and industrial environments often lack access to robust energy and communications infrastructure, limiting the use of modern cooking systems and posing safety hazards due to reliance on flammable fuels, which can exacerbate fire risks in isolated areas.

Innovation Solution

An intelligent cooking system that utilizes a solar-powered electrolyser to produce hydrogen as an on-demand fuel source, eliminating the need for traditional power grids and reducing fire hazards by using a non-flammable energy storage method, integrated with cloud-based value-added services for remote monitoring and control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If natural gas is used for cooking, then cooking function is provided, but carbon monoxide gas is generated causing safety hazards

Engineering Contradiction:
Improvecooking safetyVSAvoidcarbon monoxide generation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful carbon monoxide byproduct of natural gas combustion into useful hydrogen fuel through a catalytic conversion system. The CO generated during cooking is captured and converted to H2, which is then stored and used to power an fuel cell that generates electricity for kitchen appliances, transforming a safety hazard into a beneficial resource.

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

2Adaptability or versatility

If multiple kitchen appliances are operated simultaneously, then cooking functionality is enhanced, but electricity consumption increases

Engineering Contradiction:
Improveappliance functionalityVSAvoidelectricity consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent merges the waste CO from natural gas combustion with the electrical power generation function by integrating a catalytic converter and fuel cell system into the kitchen appliance infrastructure. This combines previously separate functions (cooking and power generation) into an integrated system where waste resources from one process fuel another.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system generates its own electricity through the fuel cell powered by converted CO, making the kitchen appliance system self-sufficient for power needs. The hydrogen produced from CO conversion is stored and used to power appliances, reducing dependence on external electricity grids.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If hydrogen is produced from carbon monoxide, then hydrogen fuel is generated, but additional processing equipment is required

Engineering Contradiction:
Improvehydrogen productionVSAvoidprocessing equipment
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The catalytic converter serves multiple functions: it acts as an exhaust treatment device for CO removal, a hydrogen production plant, and a fuel source for the fuel cell. This multi-functionality reduces the need for separate dedicated equipment for each function, simplifying the overall system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)
