Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large-size prefabricated construction segments require additional reinforcements and framework in high-load areas, leading to increased construction costs and complexity.
Innovation Solution
The use of large-size prefabricated multilayer construction segments with cement-and-fibre or gypsum-and-fibre boards, polyurethane foam filling, and PVC spacing inserts, along with reinforcement elements like carbon or glass fibre grids, allows for efficient assembly and reinforcement, enabling structural, insulation, and finishing features in a single system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional reinforcing elements and framework are added in high-load areas, then structural strength is improved, but device complexity and construction cost increase
Solution Approach 1:
The patent combines the reinforcing element directly with the cladding board by embedding it during the manufacturing process. The reinforcing element is integrated into the cladding board structure, eliminating the need for separate reinforcing components and simplifying assembly. This merging of functions resolves the contradiction by maintaining structural strength while reducing device complexity.
Solution Approach 2:
The patent uses composite materials by combining cladding boards with embedded reinforcing elements created from fiber materials. The reinforcing element is formed from fiber-based composite materials that are integrated with the cladding board during manufacturing. This composite approach provides structural strength while avoiding the complexity of separate metal framework systems.
2Strength
If additional reinforcing elements and framework are added in high-load areas, then structural strength is improved, but construction cost increases
Solution Approach 1:
The patent combines the reinforcing element directly with the cladding board by embedding it during the manufacturing process. The reinforcing element is integrated into the cladding board structure, eliminating the need for separate reinforcing components and simplifying assembly. This merging of functions resolves the contradiction by maintaining structural strength while reducing device complexity.
Solution Approach 2:
The reinforcing element is manufactured and embedded into the cladding board during the preliminary manufacturing process rather than being added during construction. This preliminary action eliminates the need for additional on-site materials and labor, reducing construction costs while maintaining structural strength.
3Productivity
If large-size prefabricated segments are used, then construction speed is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by providing spacing inserts at specific locations where cladding boards meet, rather than requiring precision throughout the entire structure. The spacing inserts are strategically placed at joint locations to accommodate assembly tolerances, allowing large-size prefabricated segments to be manufactured with standard precision while achieving accurate assembly through localized adjustments.
Solution Approach 2:
The spacing insert acts as an intermediary element between cladding boards during assembly. It mediates the connection by providing the necessary spacing and alignment at joints, allowing large-size segments to be assembled with standard manufacturing tolerances without requiring high-precision manufacturing. The spacing insert compensates for dimensional variations and ensures proper assembly.
