A multi-axial wave energy conversion device featuring a main body with permanent magnet generating assemblies, including stator and rotor structures capable of rotating or swinging, and hydraulic power generation devices, allowing for energy conversion from wave movements along different directions with a specific ratio of rotor to stator slots for efficient electricity generation at low speeds and small angles, independent of fixed wave direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wave energy conversion device uses a single axis of rotation, then the structure is simple, but it cannot effectively convert wave energy from multiple directions
Solution Approach 1:
The patent transitions from a single-axis rotation mechanism to a multi-axial rotation mechanism by adding a second rotation axis perpendicular to the first. The first rotating component rotates around a first axis, while the second rotating component rotates around a second axis that is perpendicular to the first axis, enabling the device to capture wave energy from multiple directions simultaneously.
2Reliability
If the device requires large wave amplitudes and fixed wave directions for efficient energy conversion, then the energy conversion efficiency is high, but the reliability and stability of electricity generation decrease due to the irregular and unstable nature of wave energy
Solution Approach 1:
The patent employs dynamic adaptation mechanisms where the rotating components can adjust their positions and orientations in response to varying wave conditions. The first and second rotating components can independently rotate to align with the dominant wave direction, allowing the device to maintain efficient energy conversion across different wave scenarios rather than requiring fixed optimal conditions.
3Adaptability or versatility
If the device uses complex mechanical structures to handle irregular wave movements, then the adaptability to wave conditions improves, but the maintenance costs increase
Solution Approach 1:
The patent divides the wave energy conversion system into separate modular components: a first rotating component for capturing wave motion around a first axis, and a second rotating component for capturing wave motion around a second axis. Each component can be independently manufactured, maintained, and replaced, simplifying maintenance procedures compared to a fully integrated complex mechanism.
