Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional on-site construction is used, then flexibility in material selection is maintained, but delivery times are long and labor costs are high
Solution Approach 1:
The patent applies preliminary action by prefabricating complete façade modules in the factory before delivery to site. These modules include pre-assembled cladding panels, ventilation components, and insulation layers, allowing construction to proceed rapidly once delivered. This eliminates the need for on-site fabrication and significantly reduces delivery and assembly times.
Solution Approach 2:
The patent segments the façade system into modular prefabricated units that can be independently manufactured and then assembled on-site. Each module is a self-contained unit with standardized connection elements, enabling parallel production and rapid assembly, thereby increasing productivity while reducing overall delivery time.
2Productivity
If prefabricated modules are used, then construction speed increases, but lifting and fixing large, heavy modules becomes difficult
Solution Approach 1:
The patent divides the façade into smaller modular segments rather than using single large heavy modules. Each module is designed with optimized dimensions and weight distribution, making them easier to handle, lift, and fix while maintaining high assembly speed through standardized connection systems.
Solution Approach 2:
The patent introduces intermediary lifting and fixing devices as part of the module system. These include built-in lifting points, attachment mechanisms, and connection elements that facilitate easy handling and secure fixation of modules during assembly, eliminating the need for heavy external lifting equipment.
3Productivity
If traditional ventilated façades are constructed, then ventilation function is achieved, but adequate enclosure and insulation properties are difficult to obtain
Solution Approach 1:
The patent merges multiple functions into the prefabricated modules: the cladding panels integrate ventilation channels, insulation layers, and enclosure elements in a single unified component. This combining of functions ensures that adequate insulation and enclosure properties are achieved while maintaining construction efficiency through modular assembly.
Solution Approach 2:
The patent employs composite materials in the prefabricated modules, combining different materials with complementary properties to achieve superior insulation and enclosure performance. The modules use composite construction that integrates insulating materials, weather-resistant cladding, and structural elements in a unified design that delivers reliable performance.
4Ease of manufacture
If modular construction is used, then labor costs decrease, but obtaining adequate moisture barrier and airtightness becomes challenging
Solution Approach 1:
The patent applies preliminary action by pre-installing moisture barrier layers and airtight sealing elements during factory fabrication of the modules. These protective layers are integrated into the module construction before delivery, ensuring proper installation and sealing without requiring complex on-site assembly procedures, thereby maintaining manufacturing efficiency while achieving reliable moisture and air barriers.
