Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wave energy generation devices are deployed independently, then wave energy can be harvested, but energy conversion efficiency is low and power generation cost is high
Solution Approach 1:
The patent combines wind energy and wave energy generation devices into a single integrated floating platform system. The wind turbine and OWC wave energy converter share common structures including the floating platform, mooring system, and electrical equipment, enabling simultaneous harvesting of both wind and wave energy to improve overall energy conversion efficiency while reducing duplicate infrastructure costs
Solution Approach 2:
The floating platform serves multiple functions: it supports the wind turbine, houses the OWC wave energy converter, provides a common mooring system, and contains shared electrical equipment. This multi-functional design allows the system to generate electricity from both wind and wave resources using a single platform structure, reducing the cost per unit of energy generated
2Reliability
If wave energy generation devices are deployed independently, then wave energy can be harvested, but reliability is low
Solution Approach 1:
The integrated system combines wind and wave energy generation on a single floating platform, where the wind turbine and OWC device can compensate for each other's generation shortfalls. When wind conditions are poor, wave energy continues to generate electricity, and vice versa, thereby improving overall power generation reliability while sharing common infrastructure to control costs
3Productivity
If separate wind and wave energy systems are deployed, then both energy sources can be utilized, but marine space resource utilization efficiency is low
Solution Approach 1:
The patent integrates wind turbine and OWC wave energy converter equipment on a single floating platform, maximizing the utilization of marine space resources. The compact integration allows both energy sources to be harvested from the same location without requiring separate offshore installations, thereby improving space utilization efficiency while the modular design manages system complexity
