Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ports are directly open to air for combustion, then air supply for combustion is sufficient, but excess air enters the chamber and disturbs the flame stability
Solution Approach 1:
A flow control head with adjustable flow control members is introduced as an intermediary device between the ambient air and the combustion chamber. This mediator allows precise regulation of air flow rate into the chamber, ensuring sufficient oxygen supply for combustion while preventing excess air from entering and disturbing the flame stability.
2Temperature
If ports are open for cooling the base, then base temperature is controlled, but wind disturbances affect the vortex flame
Solution Approach 1:
The flow control head serves as a protective intermediary that shields the vortex flame from direct wind exposure while still allowing controlled cooling air flow to the base. The adjustable flow control members regulate the cooling air rate, maintaining base temperature control without exposing the flame to harmful wind disturbances.
3Device complexity
If fixed configuration is used for simplicity, then device complexity is reduced, but ability to adjust flame size is lost
Solution Approach 1:
The flow control head incorporates adjustable flow control members that allow dynamic modification of air flow rate and flame characteristics. This dynamic capability enables users to adjust flame size and combustion intensity according to different operational requirements, transforming a static device into an adaptable system without excessive complexity.
4Ease of operation
If no airflow control is provided, then device operation is simple, but excess air creates unstable combustion
Solution Approach 1:
The flow control head is designed with intuitive adjustable flow control members that allow users to self-regulate air flow rate based on observed flame characteristics. This self-service mechanism enables operation simplicity while maintaining combustion stability, as users can independently adjust the system to achieve optimal performance without complex control systems.

AI summary
An adjustable vortex flame device includes a control head (10) delimiting a through hole with an opening and including a flow guiding mechanism (20) 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 (40) is disposed above the control head and delimits a space fluidly connecting to the through hole.
