Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a floating body platform is used in offshore photovoltaic power generation, then the system can be installed in deep waters and is movable and reusable, but the platform is subjected to six-degree-of-freedom motion caused by ocean currents, waves, and winds, leading to fatigue load accumulation on mooring devices and connection parts
Solution Approach 1:
The floating body platform is divided into multiple modular floating bodies (11) connected by connecting frames (200). Each floating body unit group (10) can independently absorb and distribute wave impact energy, reducing the cumulative fatigue load on individual mooring devices and connection parts while maintaining overall system stability.
Solution Approach 2:
The connecting frames (200) and socket frames (100) are designed with specific geometric structures (inverted trapezoidal cross-section, hexagonal truss configuration) that combine multiple structural elements to create a composite system capable of withstanding complex marine environmental forces while maintaining durability.
2Productivity
If the floating body platform covers a large sea surface area to increase power generation capability, then more photovoltaic panel modules can be installed, but local differences in external forces from tidal phenomena reduce the durability of parts of the platform
Solution Approach 1:
The large-scale floating body platform is segmented into multiple floating body unit groups (10), each capable of independently withstanding local external forces. This modular approach allows the platform to cover large sea surface areas for enhanced power generation while distributing mechanical stresses across numerous connection points, preventing localized durability degradation.
Solution Approach 2:
Each floating body unit group (10) is designed with specific structural characteristics suited for local environmental conditions. The modular design allows different units to be optimally configured for their specific locations, accounting for variations in wave patterns, currents, and tidal forces across the extended platform area.
3Ease of manufacture
If traditional platform structures are used, then installation is simpler, but the platform cannot efficiently distribute wave impact energy, leading to excessive motion and reduced stability
Solution Approach 1:
The platform uses multiple standardized floating body unit groups (10) that can be manufactured and assembled using similar processes. Each unit group incorporates hexagonal truss structures and connecting frames (200) designed for efficient wave energy distribution, achieving enhanced stability through modular replication rather than complex custom fabrication.
Solution Approach 2:
The hexagonal truss structure and inverted trapezoidal cross-section of connecting frames provide geometric curvature and angular distribution that efficiently channel and disperse wave impact energy throughout the platform structure, improving stability while maintaining manufacturability through standardized geometric forms.
