Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If building blocks are made of reinforced concrete to increase mechanical strength for multi-story buildings, then the mechanical strength is improved, but the weight increases making transportation and assembly difficult
Solution Approach 1:
The patent applies composite materials by combining a metal frame structure with concrete infill panels. The metal frame provides the primary structural strength and load-bearing capacity, while the concrete panels fill the spaces within the frame to provide additional strength and stability. This composite approach allows the building blocks to achieve the necessary mechanical strength for multi-story construction without requiring the entire block to be made of heavy reinforced concrete, thereby reducing overall weight while maintaining structural integrity.
2Weight of moving object
If building blocks are made lighter using wood or metal, then transportation becomes easier, but fire resistance and mechanical stability are reduced
Solution Approach 1:
The patent combines metal and concrete materials to create building blocks that achieve an optimal balance between weight, fire resistance, and mechanical stability. The metal frame provides structural integrity and fire resistance, while the concrete panels contribute to both fire resistance and mechanical stability. This composite construction ensures that the building blocks maintain adequate fire resistance and mechanical stability while being lighter than traditional reinforced concrete blocks, facilitating easier transportation and assembly.
3Strength
If the number of floors to be supported increases, then the mechanical strength requirement increases, but the weight of building blocks increases making assembly more difficult
Solution Approach 1:
The patent employs composite materials consisting of a metal frame with concrete infill panels to create building blocks with optimized strength-to-weight ratio. The metal frame provides the necessary mechanical strength to support multiple floors, while the concrete panels enhance structural integrity. This composite construction achieves the required mechanical strength for multi-story buildings without proportionally increasing weight, thereby maintaining ease of transportation and assembly even as the number of supported floors increases.
4Reliability
If traditional concrete building blocks are used to ensure fire resistance, then fire resistance is improved, but thermal comfort is reduced
Solution Approach 1:
The patent combines metal and concrete materials in a composite building block structure that balances fire resistance with thermal comfort. The metal frame provides excellent fire resistance, while the concrete panels contribute to fire protection and thermal mass. The design allows for integration of insulation materials within the composite structure, improving thermal comfort by reducing heat transfer while maintaining the fire resistance properties of both metal and concrete materials.

AI summary
The invention relates to a building block (1) for constructing a building (2) comprising a floor (3) and walls (4). One of the walls (4) comprises a box-out. The walls (4) are attached to the floor (3) and to one another. The floor (3) comprises a support made of wood-concrete and defines grooves. A metal frame formed by a plurality of metal rods is arranged in the grooves. At least first metal rods project from the ends of first grooves. Concrete fills the grooves and completely covers the metal frame and the support. The walls (4) are made of wood-concrete and define on their outer face a vertical groove extending over the height of the walls (4) and opening onto the first metal rods projecting from the support.
