Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal nets are used for containment structures, then containment function is achieved, but weight and structural complexity increase significantly
Solution Approach 1:
The patent employs composite reinforcement strips consisting of a polymeric coating capsule containing longitudinal reinforcement fibres. This composite structure provides the necessary mechanical strength for containment while significantly reducing weight compared to traditional metal net systems. The fibres provide tensile strength while the polymeric matrix protects them and enables flexibility.
Solution Approach 2:
The invention uses flexible reinforcement strips with a polymeric coating that can deform and adapt to dynamic loads. These thin, flexible strips are interwoven to create a containment structure that is both lightweight and mechanically effective, replacing heavy rigid metal frameworks.
2Reliability
If metal nets are used for containment structures, then containment function is achieved, but corrosion resistance deteriorates due to exposure to atmospheric agents
Solution Approach 1:
The reinforcement strips use a polymeric coating capsule that encapsulates the reinforcement fibres, protecting them from atmospheric corrosion. The polymeric material is inherently resistant to rust and degradation from moisture and chemicals, eliminating the corrosion issues plaguing metal net systems.
Solution Approach 2:
The polymeric coating provides a protective layer that prevents direct exposure of the reinforcement fibres to corrosive environments, effectively creating a corrosion-resistant composite material that maintains its integrity over time without rusting like metal.
3Reliability
If concrete blocks connected by flexible cables are used for marine containment, then containment function is achieved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent employs flexible reinforcement strips that can be interwoven to create containment structures adaptable to various geometries. These flexible strips replace rigid concrete blocks and complex cable assemblies, simplifying the overall structure while maintaining containment effectiveness in marine environments.
Solution Approach 2:
The composite reinforcement strips combine the flexibility needed for complex geometries with the strength required for containment. This single composite element replaces multiple components (concrete blocks, cables, connectors), significantly reducing device complexity and implementation difficulty.
4Strength
If reinforcement strips are tightly interwoven without gaps, then structural strength is improved, but adaptability to dynamic loads and punching resistance decrease
Solution Approach 1:
The patent introduces controlled gaps between the interwoven reinforcement strips, allowing the structure to dynamically adjust to applied loads. The strips can slide relative to each other within these gaps, enabling the containment structure to adapt to punching forces and dynamic impacts while maintaining overall structural integrity.
Solution Approach 2:
The invention varies the spacing and configuration of reinforcement strips to create optimal gap patterns. This parameter optimization allows the structure to balance strength and adaptability, with gaps sized to permit controlled movement under load while maintaining sufficient structural support.
