Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional concrete bases are used, then load-bearing capacity and stability are ensured, but weight increases leading to higher transportation and installation costs
Solution Approach 1:
The patent employs a composite structure combining steel plates for structural framework with polymer materials for reinforcement and soil interaction. This composite approach provides high strength-to-weight ratio, ensuring load-bearing capacity while significantly reducing overall base weight compared to conventional concrete bases.
Solution Approach 2:
The base is divided into multiple steel plates arranged in a three-dimensional structure, allowing optimized material distribution. Critical load-bearing areas use thicker steel plates, while less critical areas use thinner plates or polymer reinforcement, reducing overall weight while maintaining structural integrity.
2Stability of the object's composition
If conventional concrete bases are used, then structural stability is ensured, but installation complexity and weather dependency increase
Solution Approach 1:
The base consists of multiple modular steel plates that can be manufactured separately and assembled on-site. This segmentation simplifies manufacturing and installation processes, reducing weather dependency compared to pouring large concrete bases that require continuous construction under specific weather conditions.
Solution Approach 2:
The patent changes the material state from concrete (requiring mixing, pouring, and curing) to pre-fabricated steel plates with polymer reinforcement. This parameter change eliminates the curing process, allowing installation to proceed independently of weather conditions and significantly reducing installation complexity.
3Weight of moving object
If steel plates with polymer reinforcement are used, then weight is reduced, but structural complexity increases
Solution Approach 1:
The combination of steel plates and polymer reinforcement creates a composite structure where each material complements the other. Steel provides structural framework and tensile strength, while polymer provides corrosion resistance and soil interaction properties, achieving weight reduction without sacrificing structural integrity.
Solution Approach 2:
Polymer reinforcement is strategically placed in specific locations where it provides maximum benefit, such as areas requiring corrosion resistance or soil interaction. This localized application reduces overall material complexity while maintaining structural performance in critical areas.
4Ease of operation
If tapered ends are added to plates, then soil penetration is improved, but manufacturing complexity increases
Solution Approach 1:
The tapered ends of the steel plates feature curved or angled surfaces rather than sharp edges. This curvature improves soil penetration by distributing contact pressure and reducing resistance during installation, while the simplified curved geometry is easier to manufacture using standard metalforming processes compared to complex multi-faceted shapes.
