Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If polystyrene foam concrete is used for building construction, then heat and sound insulation properties are improved, but the structure does not breathe due to polystyrene being not air permeable
Solution Approach 1:
The patent uses a composite material system combining polystyrene foam concrete with natural fibers (hemp, flax, or other plant fibers) embedded within the foam matrix. This composite structure maintains the thermal insulation properties of polystyrene foam while introducing breathability through the natural fiber network, allowing vapor transmission while preserving energy efficiency.
2Reliability
If steel wire net-cage is used for fire protection, then fire resistance is improved, but the steel loses its temper at 400-500° C. and can resist fire for up to 30 minutes only
Solution Approach 1:
The patent changes the material parameter from steel to natural fibers (hemp, flax, or other plant fibers) that have superior heat resistance properties. These natural fibers maintain their structural integrity at temperatures up to 200-300°C and do not lose their temper like steel, providing enhanced fire resistance without the temperature limitations of metal reinforcements.
3Strength
If permanent formwork is used to support weight and mold pieces, then structural support is improved, but the building structure does not allow joining of wall section higher than 3-4 rows due to concrete forces apart permanent formwork elements
Solution Approach 1:
The patent segments the wall construction into modular units with interlocking mechanisms. Each wall section can be independently manufactured and then assembled vertically without requiring permanent formwork support for the entire height. The segmentation allows wall sections to be joined beyond 3-4 rows by using interlocking features that distribute loads effectively, eliminating the need for continuous permanent formwork.
4Strength
If concrete is used for wall construction, then structural strength is improved, but construction time is extended due to technological drying requirements
Solution Approach 1:
The patent changes the material composition by replacing traditional concrete with polystyrene foam concrete containing natural fibers. This parameter change accelerates the drying process while maintaining structural strength, reducing construction time without compromising the mechanical properties of the wall structure.
5Reliability
If steel wire net-cage is used for wall framework, then fire protection is improved, but heavier objects cannot be fastened into the wall
Solution Approach 1:
The patent uses a composite material system where natural fibers are embedded in polystyrene foam concrete, creating a material that combines fire resistance with enhanced mechanical bonding properties. This composite structure allows for effective fastening of heavier objects through the fiber-concrete matrix while maintaining fire protection, overcoming the limitation of steel wire net-cages.
