Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If large commercial wind turbines are used, then significant power generation is achieved, but installation cost and structural complexity increase greatly
Solution Approach 1:
The patent divides the wind power generation system into multiple small modular units (wind cells) that can be independently installed and stacked. Each wind cell contains its own rotor, generator, and mounting structure, allowing distributed power generation without requiring a single large complex turbine structure.
Solution Approach 2:
The patent transitions from horizontal ground-based installation to vertical wall-mounted stacking. Multiple wind cells are stacked vertically on building walls, utilizing the vertical dimension for power generation in urban environments where horizontal space is limited.
2Power
If large commercial wind turbines are used, then significant power generation is achieved, but installation space requirements increase
Solution Approach 1:
The patent utilizes vertical wall space for mounting wind cells, transforming the installation from horizontal ground occupation to vertical wall utilization. This enables power generation in urban buildings with limited ground space.
Solution Approach 2:
Multiple wind cells are stacked vertically one on top of another, nesting them in the vertical dimension. Each wind cell is self-contained and can be nested within the overall wall mounting structure, maximizing space utilization.
3Reliability
If small-scale wind turbines are mounted away from structures, then turbulent flow from structures is avoided, but installation flexibility is reduced
Solution Approach 1:
The rotor blades are designed with specific airfoil sections and twist distributions optimized for extracting energy from turbulent boundary layer flows. This local optimization allows the small wind cells to effectively operate in the turbulent flow conditions near building walls that would be unsuitable for larger turbines.
Solution Approach 2:
The patent changes the operating parameters by designing rotors with lower tip speed ratios and higher solidities, making them suitable for low-speed turbulent flows near walls. This allows installation flexibility in urban environments while maintaining reliability through parameter optimization for the specific flow regime.
