Solution Overview
Problem
Conventional wind energy power generation systems face challenges in space requirements and instability due to varying wind directions, necessitating remote locations and inconsistent energy production.
Innovation Solution
The apparatus incorporates a rotatable blade unit with upright blades and a wind-collecting unit featuring non-flat plates and adjustable auxiliary plates, which guide wind from different directions onto the blades, ensuring stable energy generation through a control unit and driving units that adjust the wind-collecting channels based on wind direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional windmill with tall prop and long blades is used, then wind energy conversion capability is improved, but space requirement increases and installation location is restricted to remote areas
Solution Approach 1:
The patent employs a rotatable wind-collecting unit that can dynamically adjust its orientation to face wind from different directions. This dynamic adaptation allows the same compact structure to capture wind energy effectively without requiring the large fixed space of conventional windmills, resolving the contradiction between power conversion capability and space requirement.
Solution Approach 2:
The patent introduces a vertical rotation dimension to the wind-collecting unit, allowing it to tilt and rotate to capture wind from various directions. This dimensional addition enables effective wind capture in a compact horizontal footprint, eliminating the need for remote locations with large unobstructed spaces.
2Device complexity
If a fixed blade arrangement is used, then structure simplicity is maintained, but stable electric generation from various wind directions cannot be ensured
Solution Approach 1:
The wind-collecting unit is designed to rotate and tilt dynamically in response to wind direction changes, maintaining optimal alignment with the wind flow. This dynamic adjustment ensures consistent and stable electric generation from various wind directions while adding only minimal structural complexity through the rotation mechanism.
Solution Approach 2:
The system incorporates wind direction detection and uses this feedback to automatically adjust the orientation of the wind-collecting unit. This feedback mechanism ensures the blades remain optimally positioned relative to the wind direction, maintaining stable power generation without requiring complex manual intervention.

AI summary
An apparatus for generating electric power from wind energy includes a blade device (6) rotatable relative to a base (3) to convert wind energy into a mechanical rotary power output, and having an upright rod (61) connected with upright blades (62) and coupled to a generator (4) in the base (3) to convert the mechanical rotary power output into electric power. Each blade (62) has spaced wind-collecting ribs (623) extending vertically from a first side surface (621) thereof, thereby defining a wind-collecting space (620) between any two adjacent wind-collecting ribs (623). A wind-collecting unit (5) includes upright plates (51) mounted on the base (3), angularly equidistant and disposed around the blade device (6). Any two adjacent plates (51) define an inwardly converging wind-guiding channel (50) therebetween. Theplates (51) are non-flat so that wind is guided by the plates (51) to blow onto the first side surfaces (621) of the blades (62) via the wind-guiding channels (50).
