Engineering Contradiction Analysis
1Productivity
If wave power generation device, solar power generation devices and wind power generation device are integrated on a floating platform, then resource sharing and multi-energy complementation are achieved, but device complexity increases
Solution Approach 1:
The patent integrates wave power generation devices, solar power generation devices, and wind power generation devices onto a single floating platform. This merging of multiple energy conversion systems enables comprehensive utilization of different marine energy sources (wave, solar, wind) and allows shared infrastructure including the floating platform structure, mooring systems, and electrical infrastructure, thereby achieving resource sharing and multi-energy complementation while maintaining manageable complexity through unified design
Solution Approach 2:
The floating platform is designed as a multi-functional structure that simultaneously supports wave energy conversion, solar photovoltaic generation, and wind energy generation. The platform serves multiple purposes: providing structural support for all three energy systems, serving as a common base for electrical equipment and control systems, and enabling integrated energy management. This universal design allows a single structure to fulfill multiple functions that would otherwise require separate installations
2Productivity
If wave power generation device uses oscillating water column type with front wallboard pitching motion, then wave energy conversion efficiency is improved, but device complexity increases
Solution Approach 1:
The wave power generation device employs a dynamic oscillating water column mechanism where the front wallboard performs pitching motion around a rotating shaft in response to wave forces. This dynamic design allows the structure to actively adapt to varying wave conditions, optimizing energy capture across different wave heights and frequencies. The rotating shaft and hinge supports enable continuous angular movement, transforming irregular wave motion into rotational mechanical energy that drives the air turbine and generator system
Solution Approach 2:
The oscillating water column device utilizes the natural oscillation and vibration of water columns driven by wave action. The pitching motion of the front wallboard creates periodic changes in water column volume and pressure, generating oscillating airflow that drives the air turbine. This mechanical vibration approach converts kinetic energy from wave motion into rotational energy through the coupled rotation of the wallboard, shaft, and turbine, achieving efficient energy conversion without complex mechanical transmissions
3Area of stationary object
If cage culture is arranged in underwater space of floating platform, then space utilization is improved, but structural requirements and complexity increase
Solution Approach 1:
The culture cages are nested within the underwater space of the floating platform structure. The platform's hull or submerged compartments are designed to accommodate one or more culture cages, effectively utilizing the three-dimensional space below the waterline. This nesting arrangement allows the culture system to be integrated into the platform's structural framework rather than requiring separate independent installations, optimizing space utilization while leveraging the platform's existing structural support capabilities
