Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current construction solutions using precast concrete elements lack a comprehensive approach to integrate all necessary features for a habitable building, requiring multiple specific elements and traditional on-site construction methods, which are time-consuming and costly.
Innovation Solution
A multilaminar precast concrete construction system comprising vertical and horizontal elements, manufactured in a factory, with layers including a resistant facade, insulation, structural concrete, and internal finishing, connected by stainless steel or glass fibre elements, and incorporating technical installations, to facilitate efficient on-site assembly and reduce construction time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional construction methods are used with multiple separate precast elements, then each element can be optimized for its specific function, but the construction time increases and the number of on-site operations increases
Solution Approach 1:
The patent merges multiple separate precast elements (facade panels, insulation layers, structural components, and technical installations) into a single integrated multilaminar precast concrete element. This consolidation eliminates the need for multiple separate on-site assembly operations, directly reducing construction time while maintaining functional optimization through the layered structure.
Solution Approach 2:
The integrated precast element performs multiple functions simultaneously: structural support, thermal insulation, facade finishing, and housing technical installations. This multi-functionality approach allows a single element to replace what would traditionally require multiple separate components, reducing both construction time and the number of on-site operations.
2Ease of manufacture
If multiple separate precast elements are used, then each element can be manufactured independently, but the number of on-site assembly operations increases and costs increase
Solution Approach 1:
The patent combines multiple independently manufacturable layers (facade layer, insulation layer, structural concrete layer, and technical installation layer) into a single integrated element. Each layer can be manufactured using standard precast concrete techniques, but their integration into one element reduces the total number of assembly operations required on-site.
3Ease of operation
If traditional construction methods are used, then on-site work can be performed with basic equipment, but construction costs increase and quality control decreases
Solution Approach 1:
The patent moves complex manufacturing operations to the factory setting, where multilaminar elements with integrated technical installations and insulation layers can be produced with controlled quality. This preliminary action in the factory reduces on-site complexity while improving quality control, and the economies of scale in factory production help offset the increased manufacturing complexity.
