Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional hydro turbine configurations are used, then the structure is simple and easy to manufacture, but the energy conversion efficiency and adaptability are limited
Solution Approach 1:
The patent implements a nested configuration where inner turbine blades are positioned inside an outer envelope, creating a multi-layered flow path. The fluid flows through the inner blades first, then continues to the outer envelope, maximizing energy extraction in sequence. This nested arrangement allows complex functionality to be achieved while maintaining a compact, manufacturable structure.
Solution Approach 2:
The patent incorporates adjustable blades that can change their angle or position dynamically based on flow conditions. This dynamic adjustment capability allows the turbine to adapt to varying fluid velocities and directions, optimizing energy conversion efficiency across different operating conditions while maintaining a relatively simple overall structure.
2Device complexity
If fixed configuration turbines are used, then the device complexity is low, but the adaptability to different flow conditions and applications is limited
Solution Approach 1:
The patent designs a universal turbine system that can handle multiple flow types (axial, radial, and mixed flows) and different fluid conditions through its adjustable blade mechanism. The same basic structure can be adapted to various applications by modifying blade angles and positions, eliminating the need for completely different turbine designs for different conditions.
Solution Approach 2:
The adjustable blade mechanism allows the turbine to dynamically adapt its configuration based on incoming flow characteristics. Blades can be repositioned to optimize performance for different flow velocities, directions, and volumes, providing high versatility while maintaining a relatively simple adjustable structure rather than requiring multiple fixed configurations.
3Device complexity
If single-direction flow turbines are used, then the structure is simpler, but the ability to handle bidirectional and variable flow is limited
Solution Approach 1:
The patent employs dynamically adjustable blades that can change their orientation to accommodate bidirectional and variable flow conditions. When flow direction changes, the blades can be repositioned to maintain optimal attack angles, allowing the turbine to efficiently extract energy from flows coming from different directions without requiring completely separate flow paths.
Solution Approach 2:
The turbine is divided into separate inner and outer blade systems that can independently adjust to different flow conditions. This segmentation allows each blade system to be optimized for specific flow patterns while working together to handle complex bidirectional flows, achieving versatility without requiring an overly complex integrated flow path.
4Device complexity
If conventional energy exchange mechanisms are used, then the design is straightforward, but the energy conversion efficiency is insufficient
Solution Approach 1:
The nested arrangement of inner and outer blades creates multiple stages of energy extraction within a single turbine structure. Fluid passes through the inner blades first, transferring energy, then continues to the outer envelope where additional energy is extracted. This multi-stage nested configuration significantly improves overall energy conversion efficiency compared to single-stage designs while maintaining a compact and relatively simple integrated structure.
