Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional cementitious materials are used with precast steel cables for building panels, then structural strength can be achieved, but thermal insulation and sound insulation performance deteriorate
Solution Approach 1:
The patent employs a composite panel structure consisting of two cementitious material layers (first and fifth layers) sandwiching three insulating material layers (second, fourth, and intermediate insulating layers). This composite construction combines the structural strength of cementitious materials with the thermal and sound insulation properties of insulating materials, resolving the contradiction between structural integrity and insulation performance.
2Stability of the object's composition
If cementitious panels are constructed with precast steel cables under tension, then structural stability is improved, but the panels fail to maintain solid and well-insulated walls
Solution Approach 1:
The patent divides the panel into distinct functional layers: structural cementitious layers provide stability and strength, while separate insulating material layers (second and fourth layers) provide thermal and sound insulation. The cable layer is positioned between insulating layers, allowing the structure to maintain insulation performance even under tension by segregating structural and insulating functions into different segments.
3Loss of energy
If a layered structure with multiple materials is used for insulated panels, then insulation performance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs precast steel cables that are tensioned to specified forces before the final curing of the cementitious layers. This preliminary action allows the structural framework to be established and insulated in place before the surrounding materials are fully set, simplifying the sequencing of operations and reducing on-site manufacturing complexity despite the multi-layered structure.
4Strength
If precast steel cables are used for tensioning panels, then structural integrity is maintained, but the panels cannot achieve varied shapes and sizes
Solution Approach 1:
The patent utilizes post-tensioning cables that can be tensioned to varying degrees and configurations after the panel structure is formed. This dynamic adjustment capability allows the same basic panel design to achieve different structural intensities and accommodate varied shapes and sizes, providing adaptability while maintaining structural integrity through adjustable tensioning forces.
