Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If external gas is allowed to enter the combustion chamber through simple air inlet holes, then oxygen intake is improved, but the combustion firepower is insufficient and unburned materials are produced
Solution Approach 1:
The air inlet structure is segmented into multiple components: first air inlet holes for oxygen intake, wind guide surfaces for flow direction control, and second air inlet holes for accelerated air injection. This segmentation allows each component to perform its specific function optimally, resolving the contradiction between oxygen intake and combustion firepower.
Solution Approach 2:
The patent utilizes pneumatic principles by creating controlled air flows through the wind guide surfaces and accelerating air through the second air inlet holes. The aerodynamic design of the wind guide surfaces directs external gas to form accelerated air flows that enhance combustion firepower while ensuring sufficient oxygen supply.
2Productivity
If air inlet structures are added to improve oxygen intake, then combustion efficiency improves, but device complexity increases
Solution Approach 1:
The air inlet structure serves multiple functions simultaneously: the first air inlet holes provide oxygen intake, the wind guide surfaces direct and accelerate air flow, and the second air inlet holes inject accelerated air into the combustion chamber. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while improving combustion efficiency.
3Productivity
If air flow is accelerated through the air inlet structure, then combustion firepower improves, but energy loss increases
Solution Approach 1:
The wind guide surfaces are designed to change the parameters of air flow, specifically accelerating the air and directing it at optimal angles into the combustion chamber. By carefully controlling the flow parameters through the second air inlet holes, the system achieves enhanced combustion firepower while minimizing energy loss through efficient aerodynamic design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves complete combustion of unburned materials and improves firepower by generating spirally interlaced flames, ensuring efficient burning and faster flame exit, thereby reducing unburned emissions.
Implementation Method 1
Due to a Laval effect, the air flow is accelerated when passing through the air inlet structure and flowing into the combustion chamber
Implementation Method 2
the wind guide surface being formed by extending the connecting edge to the interior of the combustion chamber and the outlet edge in the direction of the first air inlet hole, a second air inlet hole being restricted by the outlet edge, and the direction of the second air inlet hole being upwards inclined relative to the vertical virtual axis, so that gas flowing through the first air inlet hole is inclined upwards to be guided towards the interior of the inner wall
Implementation Method 3
After a plurality of second air flows are converged with flames inside the combustion chamber, the flames can be spirally interlaced
Implementation Method 4
when combustible materials are burned in the combustion chamber on the inner wall, hot air can be generated. The hot air can enter into the combustion chamber from the air inlet in the lower end of the inner wall to form a first air flow flowing upwards
Implementation Method 5
when combustible materials are burned in the combustion chamber on the inner wall, hot air can be generated

AI summary
The present disclosure relates to a combustion device capable of generating a spirally interlaced flame effect and improving combustion firepower. The combustion device includes an outer wall and an inner wall. A ventilation chamber is formed between the inner wall and the outer wall. An upper end of the inner wall is provided with a plurality of air inlet structures distributed at intervals circumferentially. A combustion chamber restricted by the inner wall is connected to the ventilation chamber through the air inlet structure. An air inlet is formed in a lower end of the inner wall. The air inlet structure includes a first air inlet hole and a guider. The guider is provided with a wind guide surface facing towards the first air inlet hole. The wind guide surface is formed by extending a connecting edge to the interior of the combustion chamber and an outlet edge in the direction of the first air inlet hole. A second air inlet hole is restricted by the outlet edge. The direction of the second air inlet hole is upwards inclined, so that gas flowing through the first air inlet hole is inclined upwards to be guided towards the interior of the inner wall.
