Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional concrete wall panels are used, then durability and concrete appearance are achieved, but weight becomes excessive and transport cost increases
Solution Approach 1:
The concrete panel is divided into multiple layers: a substrate layer, a thinset mortar layer containing concrete aggregates, and a sealant layer. This segmentation allows the panel to maintain the durability and appearance of concrete while reducing overall weight by using a lighter substrate and thinner concrete layer compared to traditional solid concrete panels.
Solution Approach 2:
The panel uses composite materials combining a substrate (such as gypsum board, plywood, or magnesium oxide board) with thinset mortar containing concrete aggregates and a sealant layer. This composite structure provides concrete-like durability and appearance while significantly reducing weight compared to traditional solid concrete panels.
2Strength
If traditional concrete wall panels are used, then structural strength is achieved, but difficulty in cutting and installation increases
Solution Approach 1:
By segmenting the panel into a substrate layer and a thinner concrete aggregate layer, the panel becomes easier to cut and install while maintaining sufficient structural strength. The substrate provides a stable base that is easier to work with than solid concrete, and the thinner concrete layer still provides the desired strength and appearance.
Solution Approach 2:
The invention changes the parameter of concrete layer thickness from traditional thick panels to a thin layer containing aggregates. This parameter change makes the panel easier to cut and install while maintaining structural strength through the use of reinforcing fibers and the composite structure.
3Adaptability or versatility
If traditional concrete panels are cut, then installation flexibility is achieved, but harmful dust generation increases
Solution Approach 1:
The panel is segmented into a substrate layer and a thin concrete aggregate layer. This segmentation reduces dust generation during cutting because the thinner concrete layer produces less dust compared to cutting through thick traditional concrete panels, while still allowing installation flexibility.
Solution Approach 2:
By changing the thickness parameter of the concrete layer to a thin layer, the amount of dust generated during cutting is significantly reduced. The thin layer can be cut more easily and produces less harmful dust while maintaining the installation flexibility needed for various design applications.
4Reliability
If traditional concrete panels are used, then durability is achieved, but transport cost and installation difficulty increase
Solution Approach 1:
The panel is segmented into multiple layers including a substrate, thinset mortar with aggregates, and sealant. This segmentation creates a product that is easier to handle and install than traditional solid concrete panels while maintaining durability through the composite structure and sealant protection.
Solution Approach 2:
The use of composite materials (substrate + thinset mortar with aggregates + sealant) creates a panel that combines the durability of concrete with the ease of installation of lighter materials. The composite structure reduces installation complexity while maintaining the durability needed for various applications.
