Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-dimensional wind field is adopted in wind tunnel tests, then the test setup is simple, but the ability to simulate complex natural wind field environments is limited
Solution Approach 1:
The wind tunnel system is divided into multiple independent fan units (horizontal flow fans, vertical flow fans, rotating flow fans) that can operate independently or in combination. Each fan unit generates a specific wind field component, allowing the system to assemble complex three-dimensional wind field environments by coordinating the segmentation-based fan units rather than relying on a single monolithic system.
Solution Approach 2:
The patent transitions from single-dimensional wind field simulation to three-dimensional multi-physics field simulation by introducing fans that generate wind in different spatial dimensions (horizontal, vertical, and rotational). This dimensional expansion enables the simulation of complex natural wind patterns such as tornadoes, crossroad winds, and other multi-directional flow scenarios that were previously inaccessible to traditional wind tunnels.
2Adaptability or versatility
If multiple types of fans are used to simulate diverse wind environments, then the diversity of wind tunnel tests is improved, but the device complexity increases
Solution Approach 1:
The patent designs a unified wind tunnel platform where multiple fan units (horizontal, vertical, rotating) share common infrastructure including the test section, control systems, and data acquisition apparatus. This multi-functional design allows a single test facility to simulate various wind field types (uniform flow, turbulent flow, rotational flow, combined flows) by differentiating fan operations rather than requiring separate dedicated facilities for each wind regime.
Solution Approach 2:
The system incorporates adjustable and movable fan units with independent control capabilities, allowing dynamic reconfiguration of wind field characteristics during testing. The fans can be positioned, oriented, and operated at variable speeds to adapt to different test requirements, providing operational flexibility that compensates for the physical presence of multiple fan units by enabling programmable wind field generation.
