Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing top burners for cookers struggle to evenly heat food, efficiently transfer fire between outer and inner burners, and prevent imperfect combustion caused by fire transfer between burners.
Innovation Solution
A top burner design featuring an outer and inner burner system with a flame transfer slit and shielding rib, along with a gas chamber for re-ignition, ensures uniform heating and reduces imperfect combustion by effectively managing flame transfer and air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fire transfer between outer and inner burners is implemented, then heating efficiency is improved, but risk of imperfect combustion increases
Solution Approach 1:
A flame transfer slit is introduced as an intermediary structure between the outer and inner burners. This slit allows controlled flame propagation from the outer burner to the inner burner, ensuring complete combustion while enabling efficient heat transfer. The slit acts as a mediator that facilitates fire transfer without causing imperfect combustion.
Solution Approach 2:
The burner system employs different structural characteristics for the outer and inner burners. The outer burner has a larger diameter and different flame hole configuration compared to the inner burner, allowing each component to have optimized local properties for its specific function while working together for overall combustion efficiency.
2Stability of the object's composition
If outer and inner burners are used simultaneously, then heating uniformity is improved, but device complexity increases
Solution Approach 1:
The burner is divided into two distinct segments: an outer burner and an inner burner, each with specific flame holes and structural characteristics. This segmentation allows the system to achieve uniform heating across different zones (outer rim and inner area) by distributing flame output appropriately, while maintaining manageable complexity through clear functional division.
Solution Approach 2:
The inner burner is nested within the outer burner structure, with the inner burner positioned centrally and the outer burner surrounding it. This nested configuration enables compact design with efficient space utilization, achieving uniform heating coverage without excessive structural complexity.
3Ease of operation
If flame holes are formed on burner cap and burner head, then flame distribution is improved, but manufacturing precision requirements increase
Solution Approach 1:
Flame holes are formed on both the burner cap and the burner head, merging the flame generation functions of these two components. This combined approach improves flame distribution and combustion efficiency, while the integration of flame hole formation into existing manufacturing processes for these components helps manage precision requirements.
