Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single burner is used for cooking, then the structure is simple, but the heating efficiency is insufficient
Solution Approach 1:
The burner is divided into multiple independent burners (first burner, second burner, third burner) that can operate simultaneously. Each burner has its own flame holes and gas supply channels, allowing parallel heating zones that increase overall heating efficiency without requiring a complete system redesign.
Solution Approach 2:
The patent introduces a vertical stacking arrangement where burners are positioned at different heights and depths within the burner body. This three-dimensional configuration allows multiple burners to occupy different spatial zones, enabling efficient use of space while maintaining independent combustion zones for enhanced heating performance.
2Reliability
If gas mixture is supplied directly to flame holes, then the combustion process is simple, but incomplete combustion occurs
Solution Approach 1:
A gas- mixing chamber is introduced as an intermediary component between the gas supply and flame holes. This chamber allows air to mix with the gas before combustion, ensuring proper air-fuel ratio for complete combustion. The mixing chamber acts as a mediator that improves combustion efficiency without requiring complex external control systems.
Solution Approach 2:
Different regions of the burner are designed with different gas supply characteristics. The patent provides separate gas supply channels for different burners, allowing each burner to receive gas at optimal pressure and composition for complete combustion. This localized optimization ensures reliable combustion across all burners simultaneously.
3Productivity
If the burner is designed for high heating power, then cooking speed increases, but contamination from liquids becomes more severe
Solution Approach 1:
The burner system is segmented into multiple independent burners positioned at different locations. This segmentation allows heat to be distributed across multiple zones, reducing the concentration of heat in any single area. Consequently, liquid contamination is minimized because no single burner creates excessive localized heat that would cause severe splattering or contamination.
Solution Approach 2:
The burner design incorporates self-cleaning features where the combustion byproducts and contaminants are naturally managed through the combustion process itself. The multiple burners create a distributed combustion pattern that prevents any single zone from becoming excessively contaminated, and the system maintains its performance without requiring external intervention.
