Solution Overview
Problem
Wind and wave power generation technologies face instability and high maintenance costs, with wind power being intermittent and prone to mechanical damage from strong winds, while wave power generation is costly and has variable energy output, making continuous and efficient energy production challenging.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wind power generation is used, then it is easy to install and has low maintenance cost, but it is unstable and frequently interrupted
Solution Approach 1:
The patent combines wave power generation facilities with wind power generation facilities at the same location, merging two different energy generation systems. The wave power generation module includes a wave energy harnessing unit with a float unit that moves with waves, connected through transmission mechanisms to generators, working in conjunction with wind power facilities to provide complementary power generation when wind is unavailable.
2Reliability
If wave power generation facilities are built, then they can provide continuous power generation potential, but they cost a lot of money to build
Solution Approach 1:
The wave power generation facilities are built in combination with wind power generation facilities at the same location, sharing common infrastructure such as foundations, cables, and maintenance facilities. This merged approach reduces the overall construction cost while maintaining the continuous power generation capability provided by the wave energy component.
3Reliability
If wave power generation is used, then it is more predictable than wind power, but the transitional period between movement and stable generation reduces efficiency
Solution Approach 1:
The patent employs a torque adjusting unit with a variable ratio transmission mechanism that dynamically adjusts the transmission ratio between the transmission shaft and generator based on wave conditions. During the transitional period when waves are first detected, the system adjusts the transmission ratio to optimize torque transfer, ensuring efficient power generation from the start of wave motion rather than waiting for stable wave conditions.
4Strength
If wind power generation operates during strong winds, then mechanical damages occur forcing shutdown, but power generation is interrupted
Solution Approach 1:
The patent converts the harmful effect of strong winds into a beneficial situation by utilizing the same strong winds to generate waves. When wind speeds are high and would normally force wind power generation to shut down to avoid mechanical damage, the system switches to wave power generation mode, where the wave energy harnessing unit captures energy from the waves generated by these strong winds, thereby maintaining power generation continuity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous, stable, and cost-effective power generation by synchronizing wave and wind energy output, reducing downtime and maintenance costs, and leveraging the predictability of wave energy to complement wind power, thus addressing the limitations of individual technologies.
Implementation Method 1
The wave energy harnessing unit (100) is capable of harnessing the kinetic energy generated through the motion of sea waves (30)
Implementation Method 2
as the float unit moves up and down with the sea water, the central ball screw moves in sync with the float unit and then such vertical motion passed through the bevel gear to the two one-directional bevel gear pieces
Implementation Method 3
the generator unit may receive the kinetic energy transmitted from the transmission shaft and convert it to electricity
