Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large blade is used to increase contact area with wind, then the contact area with wind is improved, but the electricity generation efficiency deteriorates
Solution Approach 1:
The invention divides the rotor assembly into multiple independent modules: a first magnetic module with first carriers, a second magnetic module with second carriers, and multiple induction modules. Each module can be independently arranged and configured. The spiral blade is also segmented into multiple sections along the column, allowing optimized wind capture while maintaining efficient magnetic interaction zones for electricity generation.
Solution Approach 2:
The invention transitions from conventional two-dimensional blade rotation to a three-dimensional magnetic field interaction system. Multiple magnetic modules are arranged at different radial distances from the column, creating layered magnetic interaction zones. The induction modules are positioned to interact with magnetic fields from multiple sources simultaneously, utilizing spatial dimensionality to enhance electricity generation efficiency beyond what a single large blade could achieve.
2Quantity of substance
If limited wind energy is used, then the wind resource availability is improved, but the electricity production deteriorates
Solution Approach 1:
The invention combines multiple magnetic fields from the first magnetic module and second magnetic module into a unified magnetic interaction system. The magnetic fields overlap and interact in the annular gaps, creating enhanced magnetic flux density. This merged magnetic field system interacts with multiple induction modules simultaneously, maximizing electricity generation from limited wind-driven rotor rotation.
Solution Approach 2:
The spiral blade design ensures continuous wind energy capture along the column length, maintaining constant rotor rotation. The multiple magnetic modules and induction modules are arranged to ensure continuous magnetic field interaction throughout the rotation cycle, eliminating dead zones and maintaining uninterrupted electricity generation from the available wind energy.

AI summary
A wind power generation device includes a rotor assembly and a stator. The rotor assembly includes a rotating member, a first magnetic module, and a second magnetic module the latter two of which are fixed on the rotating member. The rotating member has a column and a spiral blade connected to the column. The first and second magnetic modules are arranged outside the spiral blade and face each other. The rotor assembly defines an annular gap formed around the spiral blade and between the first and second magnetic modules. The stator assembly includes a frame, a positioning member connected to the frame, and an induction module fixed on the positioning member and arranged in the annular gap. The spiral blade can rotate the rotator assembly relative to the stator assembly by wind, so that a region between the first and second magnetic module sweeps over the induction module.
