Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gas hobs are unable to provide high-power heating for multiple large-sized cookware simultaneously, as they lack the necessary power levels in their burners.
Innovation Solution
A gas burner design featuring multiple flame rings of different sizes, each with its own combustion chamber and gas injector, and an air gap between them for secondary aeration, allowing for adjustable heating power by activating one, two, or all flame rings, and improving combustion efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separated gas burners of different sizes are used to provide different heating power levels, then the heating power range is improved, but the device complexity and space requirement increase
Solution Approach 1:
The burner is segmented into multiple flame rings (first, second, and third flame rings) of different sizes within a single burner structure. Each flame ring can be independently activated to provide different heating power levels, resolving the contradiction by providing versatility without requiring multiple separate burners
Solution Approach 2:
The flame rings are arranged concentrically with smaller flame rings nested within larger ones (first flame ring inside second, second inside third). This nested arrangement allows multiple heating zones to coexist in a compact single-burner configuration, providing power range adjustment without increasing overall device complexity
2Device complexity
If a single gas burner with multiple flame rings is used to provide different heating power levels, then the device complexity is reduced, but the combustion efficiency may deteriorate due to insufficient air supply
Solution Approach 1:
Air inlets are positioned below each flame ring to pre-supply primary air before combustion. This preliminary air supply ensures that each flame ring has adequate oxygen for complete combustion, preventing energy loss and maintaining high combustion efficiency in the multi-ring configuration
Solution Approach 2:
Each flame ring has its own dedicated air inlet providing localized primary air supply. This local quality approach ensures that each combustion zone receives appropriate air-gas mixture independently, optimizing combustion efficiency for each flame ring while maintaining the simplified single-burner structure
3Area of stationary object
If adjacent flame rings are placed close together to save space, then the device compactness is improved, but the combustion process deteriorates due to insufficient secondary aeration
Solution Approach 1:
Air gaps are introduced as intermediary spaces between adjacent flame rings. These gaps act as channels for secondary air to reach the combustion zones, enabling complete combustion without requiring large spacing between flame rings, thus maintaining compactness while improving combustion efficiency
4Productivity
If high-power heating is provided for multiple large-sized cookware simultaneously, then the productivity is improved, but the heating power range capability deteriorates in conventional burners
Solution Approach 1:
The burner system dynamically adjusts heating power by selectively activating different combinations of flame rings. This dynamic control allows the single burner to adapt to different cooking requirements, providing both high-power capability for multiple large cookware and lower power settings for smaller vessels, thus resolving the contradiction between productivity and adaptability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible heating power adjustment from low to high, enhancing cooking efficiency by providing multiple power stages and improving combustion through secondary aeration, allowing for simultaneous high-power heating of multiple cookware.
Implementation Method 1
Each gas injector is associated with one of said pipes for providing gas into said pipe, said pipe being adapted to receive primary air in the area of the injection holder and to provide a combustion mixture of gas and primary air
Implementation Method 2
Based on said air gaps, secondary aeration is provided which increases the effectivity of the combustion process
Implementation Method 3
said burner crown assembly enables an air flow below an outer chamber in order to provide air to said air gaps. So, in other words, air is sucked below the bottom wall portion of the burner crown assembly
Implementation Method 4
provide a combustion mixture of gas and primary air to one of said flame rings
