Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thick concrete walls are used in container construction elements, then security and protection level are improved, but weight and wall thickness increase significantly
Solution Approach 1:
The patent applies composite materials by combining concrete with metal components (steel bars, metal profiles) and non-concrete composite bars (polyethylene, wood fibre, aluminium) to create a multi-material construction element. This composite structure provides enhanced security and protection levels through the synergistic properties of different materials while optimizing the overall weight compared to solid concrete construction.
Solution Approach 2:
The construction element is segmented into distinct functional components: concrete portions providing bulk protection, metal components providing structural strength and penetration resistance, and non-concrete composite bars providing additional security features. This segmentation allows each material to contribute its specific advantages while reducing the total weight compared to homogeneous thick concrete walls.
2Reliability
If thick concrete walls are used in container construction elements, then security and protection level are improved, but transportation and handling become more difficult
Solution Approach 1:
By using composite materials with lower density components (metal profiles, non-concrete composite bars) combined with concrete, the construction element achieves high security protection levels while reducing overall weight. This weight reduction directly improves ease of transportation and handling operations.
Solution Approach 2:
The patent optimizes the thickness parameter of the construction element to a specific range that provides sufficient security protection while minimizing weight. This parameter optimization balances protection requirements with transportation and handling ease.
3Reliability
If wide cross section construction elements are used, then security and penetration resistance are improved, but wall thickness and material consumption increase
Solution Approach 1:
The patent replaces a significant portion of concrete material with metal components and non-concrete composite bars that provide equivalent or superior penetration resistance. This substitution reduces concrete material consumption while maintaining or enhancing security and penetration resistance through the high strength-to-density ratio of metal and composite materials.
Solution Approach 2:
Different materials are strategically placed in specific locations within the construction element: metal components in positions requiring high tensile and bending strength, non-concrete composite bars in positions requiring penetration resistance. This localized material placement optimizes protection performance while minimizing total material consumption.
