Building Corner Wind Turbine Conical Blade Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind turbine installations often fail to maximize wind energy capture due to suboptimal placement and design, particularly when integrated into building structures, where wind flow is not efficiently concentrated and velocity is not adequately harnessed.
Innovation Solution
A wind turbine system is mounted on a building corner with blades that rotate in a conical plane, utilizing the concave side for air impingement and angled to clear building edges, allowing for efficient energy conversion into rotational mechanical energy, which can be used for electricity generation or other purposes.

Engineering Contradiction Analysis
1Power
If wind turbines are installed on buildings to harness wind energy, then energy generation capability is improved, but wind flow concentration and velocity are insufficient due to suboptimal placement
Solution Approach 1:
The turbine is positioned at a building corner and rotates in a conical plane rather than in a traditional horizontal or vertical plane. This three-dimensional rotation allows the blades to sweep through multiple spatial dimensions, maximizing exposure to wind flow from different directions and enhancing energy capture capability.
Solution Approach 2:
The turbine utilizes the asymmetric corner geometry of the building, where three edges converge at a point. The shaft is mounted at an angle to these edges, creating an asymmetric configuration that strategically positions the rotating blades to intercept concentrated wind flow patterns formed by the building's corner structure.
2Productivity
If the turbine shaft is mounted at an angle through the corner point, then blade alignment with building edges is optimized for rotation, but structural complexity increases
Solution Approach 1:
The building corner itself serves multiple functions: it provides the mounting location for the shaft, acts as a wind flow concentration structure, and defines the spatial orientation for blade rotation. By utilizing the existing corner geometry, the design avoids the need for separate support structures, foundations, or complex mounting brackets that would otherwise be required.
3Power
If blades are configured to clear building edges during rotation, then wind energy capture is maximized, but risk of collision with building structures increases
Solution Approach 1:
The blades rotate in a conical plane that extends outward from the building corner, utilizing three-dimensional space. This conical rotation path naturally clears the building edges by elevating the blade tips above the building surface level, creating a safety margin that prevents collision while maximizing the swept area for energy capture.
