Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If ports are directly open to air to supply air for combustion, then combustion can occur, but excess air enters the chamber causing unstable flame and high base temperature
Solution Approach 1:
The patent applies local quality by providing different air supply characteristics to different regions: the base region receives controlled air flow through the base opening while the upper region receives air through ports. This creates localized air supply zones that prevent excess air from destabilizing the flame while maintaining adequate oxygen for combustion.
Solution Approach 2:
The base opening acts as an intermediary structure that mediates between the fuel source and the surrounding air. It provides a controlled interface for air entry at the base, preventing direct uncontrolled air flow into the combustion chamber while still supplying necessary oxygen for combustion.
2Use of energy by moving object
If ports are directly open to air to supply air for combustion, then combustion can occur, but wind easily disturbs the flame
Solution Approach 1:
The patent creates localized air supply zones with the base opening providing controlled air flow at the base while ports provide air at higher levels. This local differentiation protects the flame core from wind disturbances by maintaining a stable, controlled air-fuel mixture at the base where combustion is most sensitive to external disturbances.
3Reliability
If no air is supplied for combustion through ports, then flame stability improves, but the base becomes too hot to touch
Solution Approach 1:
The patent applies local quality by differentiating air supply to different regions: the base opening provides controlled air flow specifically to cool the base region while ports provide air for combustion at higher levels. This creates a localized cooling zone at the base without compromising overall flame stability.
Solution Approach 2:
The base opening serves as an intermediary cooling mechanism that introduces controlled air flow at the base to reduce temperature, acting as a thermal management interface between the hot combustion zone and the outer environment.
4Adaptability or versatility
If the device is made adjustable to change flame size, then versatility improves, but device complexity increases
Solution Approach 1:
The patent applies dynamics by making the base opening adjustable in size, allowing the device to adapt to different combustion requirements. This dynamic adjustment capability enables flame size control without requiring complex multi-component systems, as the single adjustable opening provides both flow control and sizing functionality.

AI summary
An adjustable vortex flame device includes a control head delimiting a through hole with an opening and including a flow guiding mechanism including a plurality of vanes and a flow control head inserting in the through hole. The flow control head includes a first member and a second member detachably engaging with each other and delimiting a first chamber and a second chamber connecting to each other. The two channels extend in the first member and to an outer periphery of the flow control head and connect to the first chamber. The flow control head has two flow outlets defined at distal ends of the two channels and a flow inlet defined at a distal end of the second chamber. A hollow and transparent shield is disposed above the control head and delimits a space fluidly connecting to the through hole.
