Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural wind is used to drive fan blades, then the system can generate electricity without additional energy input, but the wind speed instability causes reduced generator output or potential damage
Solution Approach 1:
The system performs preliminary action by using the Venturi structure to pre-accelerate air flow before it reaches the fan blades. The duct body creates a concentrated wind beam in advance, ensuring that the fan blades always receive sufficient wind force regardless of natural wind conditions, thus preventing both underperformance and overheating
Solution Approach 2:
The Venturi structure changes the physical parameters of air flow by reducing cross-sectional area in the narrow-diameter portion, which increases air flow speed and concentrates the wind beam. This parameter transformation ensures stable wind force delivery to the fan blades, resolving the instability issue of natural wind
2Speed
If the duct body uses a Venturi structure to concentrate air flow, then wind speed and volume are enhanced, but the structural complexity of the duct body increases
Solution Approach 1:
The duct body is segmented into three distinct portions: first wide-diameter portion, narrow-diameter portion, and second wide-diameter portion. This segmentation allows the Venturi effect to be implemented in a controlled manner only where needed (the narrow portion), while the wide portions maintain simple structures for air intake and generator housing, thus balancing complexity enhancement with functional efficiency
3Productivity
If the first tapered portion has a greater angle than the second tapered portion, then air flow acceleration is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
Different tapered portions are assigned different quality characteristics: the first tapered portion (upstream) has a greater angle for aggressive acceleration, while the second tapered portion (downstream) has a smaller angle for gentle diffusion. This local differentiation optimizes air flow control at each stage while providing clear manufacturing guidelines for each section, balancing performance with manufacturability
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 system achieves stable and continuous electricity generation by concentrating and accelerating air flow through the Venturi channel, reducing reliance on natural wind conditions and minimizing the risk of damage.
Implementation Method 1
the duct body is a Venturi channel, and when the air flows through, the air flow speed rate increasing and the pressure decreasing due to the reduced cross-portion of the narrow-diameter portion, so as to create the wind force and speed
Implementation Method 2
the duct body creates a chimney effect that causes the air to form a flow of air from the air intakes into the duct body
Implementation Method 3
through the ground air near the bottom of the tower thermal convection wind power generator of the present invention, due to the effect of the internal chimney structure of the wind power generator, the air is naturally induced to be sucked into the internal pipeline
