Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flow guide cover is used to form spiral air flow, then flame rotation is achieved, but the manufacturing process becomes cumbersome and production cost increases
Solution Approach 1:
The flow guide cover is divided into multiple air duct pieces (at least three) that are distributed around the periphery. Each air duct piece is a separate component that can be manufactured independently and then assembled, simplifying the manufacturing process while maintaining the spiral air flow function.
Solution Approach 2:
The design changes from a complete flow guide cover to discrete air duct pieces with specific geometric parameters (arc-shaped cross-section, specific dimensions). This parameterization allows for standardized manufacturing and assembly, reducing production complexity and cost.
2Power
If flame combustion is concentrated, then combustion intensity is high, but heat dissipation becomes uneven and energy efficiency decreases
Solution Approach 1:
The air duct pieces are distributed around the periphery to create localized air intake zones. This distributes the combustion process around the flame outlet rather than concentrating it at a single point, enabling more uniform heat dissipation while maintaining combustion intensity through adequate air supply at each zone.
