Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating construction elements face challenges in achieving horizontal stabilization and efficient load absorption, often requiring excessive concrete that compromises insulation quality and increases weight, making handling and installation difficult.
Innovation Solution
An insulating construction element design featuring a first and second skin made of insulating material, with a core of flat plates, and cavities for concrete pouring, which reduces the amount of concrete needed and improves insulation while ensuring structural stability through strategically placed cavities that form a trellis-like structure upon hardening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a large quantity of concrete is poured inside the internal volume of the insulating construction element, then the mechanical qualities of the wall are improved, but the insulation qualities are reduced and the weight increases
Solution Approach 1:
The internal volume is segmented into multiple cavities distributed throughout the element, allowing concrete to be poured only in specific locations rather than filling the entire volume. This segmentation enables the concrete to provide mechanical reinforcement where needed while leaving insulating material in place to maintain thermal performance.
Solution Approach 2:
Concrete is strategically positioned only in specific cavities rather than uniformly distributed throughout the entire element. This local placement provides mechanical strength and stabilization in critical areas while preserving the insulating properties of the material in other regions, thus achieving both mechanical and insulating requirements without excessive concrete.
2Strength
If a large quantity of concrete is poured inside the internal volume of the insulating construction element, then the mechanical qualities of the wall are improved, but the weight of the element increases making handling difficult
Solution Approach 1:
The internal volume is divided into discrete cavities, allowing concrete to be placed only where structurally necessary. This segmented approach significantly reduces the total volume of concrete required compared to filling the entire internal space, thereby reducing weight while maintaining essential mechanical properties.
Solution Approach 2:
Concrete is concentrated only in specific cavities rather than uniformly distributed throughout the entire element. This localized placement provides the necessary mechanical strength and stabilization in critical areas while minimizing the overall weight, making the element easier to handle and install.
3Stability of the object's composition
If two concrete skins are used in the insulating construction element, then structural stability is improved, but the weight increases and handling becomes complicated
Solution Approach 1:
The invention extracts the concrete from forming complete outer skins and instead places it only within internal cavities. This extraction approach maintains the structural stability provided by concrete while eliminating the excessive weight and handling complications associated with concrete skins.
Solution Approach 2:
The construction element uses a composite structure combining insulating material for the outer skins with strategic concrete placements within cavities. This composite approach provides structural stability through the combination of materials while avoiding the weight penalty of concrete skins, achieving both stability and reduced weight.
