Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If wave power generation devices are installed in distant seas and offshore waters, then energy generation capacity is improved, but installation cost increases due to costly subsea cables
Solution Approach 1:
The system divides the wave power generation facility into multiple modular floating units, each capable of independent operation. These units are connected to each other and to the shore via a single cable that transmits both power and control signals, eliminating the need for multiple expensive subsea cables while maintaining offshore energy generation capacity.
2Power
If onshore wave power generation installations are expanded, then energy generation capacity is improved, but spatial availability deteriorates due to limited coastal space
Solution Approach 1:
The invention transitions wave power generation from a two-dimensional onshore layout to a three-dimensional offshore floating configuration. Multiple modular units can be deployed in the water column and connected in various configurations, effectively utilizing spatial volume rather than limited coastal surface area, thereby expanding energy generation capacity without consuming additional land space.
3Adaptability or versatility
If a modular floating system with cable connections is used, then scalability is improved, but system complexity increases
Solution Approach 1:
The cable connecting the modular floating units serves multiple functions simultaneously: it transmits electrical power from the wave energy converters, carries control signals for system coordination, and provides structural support for the floating units. This multi-functionality reduces the number of separate components needed, simplifying the overall system while maintaining scalability.
