Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional vortex generator devices are used, then the basic aerodynamic function is achieved, but the mounting strength is insufficient and design flexibility is limited
Solution Approach 1:
The base is divided into multiple edge parts (first edge part, second edge part, third edge part, fourth edge part) with different functions. The first and second edge parts provide mounting surfaces with adhesive material, while the third and fourth edge parts define the aerodynamic profile. This segmentation allows independent optimization of mounting strength and aerodynamic performance.
Solution Approach 2:
The base has an asymmetric configuration with different edge parts having different lengths and orientations. The first edge part has a first length and the second edge part has a second length, creating an asymmetric mounting surface that provides both strong attachment and proper aerodynamic alignment on the curved blade surface.
2Reliability
If vortex generator devices are mounted on wind turbine blades, then aerodynamic properties are improved, but mounting errors and noise issues occur due to insufficient mounting strength
Solution Approach 1:
Adhesive material is applied to the first and second edge parts of the base before mounting. This preliminary action ensures strong bonding to the wind turbine blade surface, preventing mounting errors and reducing noise caused by loose or improperly mounted vortex generators during operation.
3Ease of operation
If the base edge parts are made straight with specific angles, then alignment with wind turbine blades is simplified, but manufacturing precision requirements increase
Solution Approach 1:
Different edge parts of the base have different geometric properties tailored to their specific functions. The first and second edge parts have straight edges with specific angles for mounting and alignment, while the third and fourth edge parts are configured for aerodynamic performance. This local differentiation allows each edge part to be optimized for its specific purpose.
