Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional patio heaters, both electric and gas-powered, are energy-intensive and produce significant CO2 emissions, posing environmental concerns and safety risks due to gas storage, making them unsuitable for outdoor use without a power connection.
Innovation Solution
A radiant heater using a combustion device for solid fuels like charcoal or coal, which operates independently of electricity and gas, featuring a combustion chamber with a fire bowl and hood design for efficient heat radiation and safety, and an air supply device for easy ignition and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If gas-powered patio heaters are used, then heating performance is achieved, but CO2 emissions and energy consumption increase significantly
Solution Approach 1:
The invention changes the fuel type parameter from gas (propane/butane) to solid fuel (charcoal/coal), fundamentally altering the combustion characteristics and emission profile while maintaining heating performance through optimized combustion chamber design and airflow control
2Adaptability or versatility
If gas bottles are used for heating, then portable heating is achieved, but safety risks from gas storage increase
Solution Approach 1:
The invention extracts and eliminates the gas storage component (gas bottle) from the system, replacing it with solid fuel that does not require pressurized storage, thereby removing the primary safety hazard while preserving portable heating capability
Solution Approach 2:
The invention converts the harmful aspect of gas storage (explosion risk, leakage) into a beneficial solid fuel form that is safer to store and handle, while the combustion process remains controlled and efficient through design features like the combustion chamber and air supply system
3Loss of energy
If electric radiant heaters are used, then heating efficiency is improved, but dependence on power connection increases
Solution Approach 1:
The invention replaces the electrical heating system (resistance heating coil) with a mechanical/chemical combustion system using solid fuel, eliminating dependence on electrical power connections while achieving efficient heat radiation through the combustion chamber design
