Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing burners used in household appliances, such as water heaters, face issues with insecure installation, inadequate gas ejection, and insufficient combustion heat intensity, leading to high nitrogen oxide emissions.
Innovation Solution
A burner design featuring multiple parallel flame distributors connected by a fastener with a compacting piece, a gas distribution device with specific gas passages, and a U-shaped cooling water pipe to enhance stability, combustion intensity, and reduce nitrogen oxide emissions, includes an igniter with bent ignition ends and a top plate with snap-fitted fire holes for improved gas utilization and cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple flame distributors are connected using traditional fastening methods, then the installation security is improved, but the device complexity increases
Solution Approach 1:
The fastener and compacting piece are merged into a single integrated component. The fastener body passes through the flame distributors while the compacting piece at its end provides the securing function, eliminating the need for separate fastening and compacting components, thus reducing device complexity while maintaining installation security
Solution Approach 2:
The fastener serves multiple functions simultaneously: it connects the flame distributors together, secures them in position, and the compacting piece at its end provides additional securing and compacting action. This multi-functional design reduces the number of separate components needed while achieving reliable installation
2Power
If the burner uses simple ejection tubes, then the device complexity is reduced, but the combustion heat intensity is insufficient
Solution Approach 1:
The ejection tubes are designed with different local characteristics - some portions have larger diameters for better gas flow, while other portions have smaller diameters for controlled ejection. The tubes are positioned at different heights and angles to create optimized local combustion zones, achieving high combustion heat intensity through localized structural variations rather than uniform complexity throughout the entire system
3Power
If the burner operates at high temperature for intense combustion, then the combustion heat intensity is improved, but nitrogen oxide emissions increase
Solution Approach 1:
The combustion process is segmented into multiple zones through the parallel arrangement of multiple flame distributors with multiple ejection tubes each. This segmentation allows different portions of the combustion process to occur at slightly different conditions, preventing sustained high-temperature zones that generate excessive nitrogen oxides while maintaining overall high combustion heat intensity through the cumulative effect of multiple combustion points
