Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If spherical structure is adopted for pressure-resistant shell, then pressure resistance is improved, but internal space utilization deteriorates
Solution Approach 1:
The pressure-resistant shell is divided into multiple sections (spherical upper section, cylindrical middle section, conical lower section) that can be independently designed and assembled. This segmentation allows each section to optimize its shape for specific functions while maintaining overall structural integrity and pressure resistance.
Solution Approach 2:
The invention transitions from traditional two-dimensional cross-sectional shapes (sphere, cylinder, annulus) to a three-dimensional composite structure combining multiple geometric forms. This dimensional integration enables simultaneous optimization of pressure resistance and internal space utilization across different spatial zones.
2Volume of moving object
If cylindrical structure is adopted for pressure-resistant shell, then internal space utilization is improved, but mechanical properties deteriorate
Solution Approach 1:
The cylindrical section is merged with spherical and conical sections to form a composite structure. The cylindrical middle section provides high space utilization, while the spherical upper section and conical lower section enhance overall mechanical properties and pressure resistance through their geometric advantages.
Solution Approach 2:
Different sections of the pressure-resistant shell are assigned different geometric qualities optimized for their specific functions. The spherical section provides superior pressure resistance, the cylindrical section maximizes internal space, and the conical section facilitates buoyancy and structural transition, creating local optimization throughout the structure.
3Strength
If annular structure is adopted for pressure-resistant shell, then pressure resistance is improved, but space expandability deteriorates
Solution Approach 1:
The annular structure is segmented into multiple thickness zones and structural layers, allowing different regions to serve different functions. The outer annular section maintains pressure resistance, while inner sections and void spaces provide expandable volume for equipment and crew, enabling space adaptability without compromising structural strength.
