Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional high-speed propeller-type turbines are used, then power generation efficiency is improved, but the size and complexity of the turbine increases, making it difficult to transport to remote locations
Solution Approach 1:
The turbine is divided into multiple independent blade modules arranged in rows along the rotor shaft. Each blade can be independently manufactured and assembled, allowing the turbine to be built in compact sections that are easier to transport and assemble at remote locations while maintaining efficient power generation through multiple blades working in parallel
Solution Approach 2:
The invention transitions from a single-blade or few-blade design to a multi-blade configuration arranged in multiple rows along the rotor shaft. This dimensional arrangement increases the total blade area and fluid engagement without significantly increasing the rotor diameter, thereby improving power generation efficiency while keeping the overall turbine compact and transportable
2Productivity
If multi-blade configurations are used, then fluid engagement is improved, but the device complexity and manufacturing difficulty increases
Solution Approach 1:
The multi-blade system is segmented into identical or similar modular blade units that can be manufactured using the same processes and then assembled in rows along the rotor. This standardization simplifies manufacturing by allowing batch production of identical components, reducing complexity despite the increased number of blades
Solution Approach 2:
The blade design incorporates specific geometric parameters such as arc-shaped cross-sections and optimized pitch angles that can be consistently replicated through standardized manufacturing processes. These parameter optimizations improve fluid engagement while the standardization of these parameters across all blades simplifies the overall manufacturing process

AI summary
A blade system, has rows of blades extending radially outward along the length and around the circumference of a rotor of a low-profile ground-mounted wind turbine which is particularly suited for use in remote locations. The wind-engaging end of each blade is arc-shaped and is turned about 120 degrees to maximize efficiency. Preferably, two rotors having the unique blade system are connected to a single, centrally located generator, and the entire unit is mounted on a frame which is rotatable on wheels about a central shaft. Further, a circular track is provided in for engaging the wheels for ease of rotation of the unit either under the direction of a PLC or in yaw.
