Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional turbine blade designs are used, then the turbine structure is simple, but energy conversion efficiency is insufficient
Solution Approach 1:
The patent applies dynamics by making the blade angle adjustable rather than fixed. The blade can change its angle of attack dynamically to optimize energy capture from fluid flow at different operating conditions, directly improving energy conversion efficiency while adding controlled complexity to the blade structure
Solution Approach 2:
The patent changes the parameter of blade angle from a fixed value to an adjustable range. By enabling the blade angle to vary within a specific range, the turbine can adapt to different flow conditions and maximize energy extraction, resolving the contradiction between efficiency and structural simplicity
2Productivity
If fixed blade angles are used, then manufacturing is simple, but energy utilization is not optimal
Solution Approach 1:
The blade design transitions from a static, fixed-angle configuration to a dynamic, adjustable-angle configuration. This allows the blade to optimize its angle of attack for maximum energy utilization while maintaining a relatively simple manufacturing approach through modular or adjustable mechanism design
3Productivity
If uniform flow channel cross-section is used, then structural design is simple, but flow energy expansion is limited
Solution Approach 1:
The patent transitions the flow channel from a uniform two-dimensional cross-section to a varying three-dimensional geometry. The channel cross-section changes along the flow direction to expand and utilize flow energy more effectively, improving energy utilization while adding geometric complexity
