Solution Overview
Problem
Existing connection elements between building walls and floors or ceilings struggle to achieve a high insulation effect while maintaining sufficient strength, often requiring a compromise between thermal separation and structural integrity.
Innovation Solution
A form module with a shape body made of mineral building material, featuring a material layer with elastic properties on its contact areas, which enhances insulation and sound decoupling while maintaining high strength through power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If known insulating connection elements are used to provide thermal separation between floor levels, then insulation performance is improved, but structural strength is reduced
Solution Approach 1:
The connection element combines concrete (mineral building material) with an elastomer layer to create a composite structure. The concrete provides structural strength and load-bearing capacity, while the elastomer layer provides thermal insulation and acoustic decoupling. This composite material approach resolves the contradiction by integrating two materials with complementary properties into a single functional element.
Solution Approach 2:
The elastomer layer is applied selectively at the contact areas where the connection element interfaces with the building wall and floor/ceiling slab. This local application of elastic material provides thermal and acoustic insulation precisely where needed at the interfaces, while the bulk of the connection element maintains its concrete structure for strength. This localized quality enhancement resolves the contradiction without compromising overall structural integrity.
2Temperature
If material layer with elastic properties is added to enhance insulation and sound decoupling, then insulation effect is improved, but device complexity is increased
Solution Approach 1:
The elastomer layer is integrated directly onto the contact surfaces of the concrete connection element, merging the insulation function with the structural element rather than adding a separate insulating component. This integration reduces device complexity by combining multiple functions (structural support, thermal insulation, acoustic decoupling) into a single unified element, while still achieving improved insulation effects.
3Strength
If fully enclosed pressure elements are used for force transmission, then structural strength is improved, but thermal insulation performance is reduced
Solution Approach 1:
The elastomer layer is applied specifically at the contact areas where pressure elements interface with the building components, rather than fully enclosing all pressure elements. This localized application maintains thermal insulation at the critical heat transfer interfaces while allowing the pressure elements to remain fully enclosed and functional for force transmission. The solution optimizes thermal performance at key locations without compromising structural integrity.
