Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating elements for wall anchor arrangements fail to effectively manage thermal bridges and absorb varying loads, limiting their versatility and efficiency in attaching components to thermally insulated building walls.
Innovation Solution
The insulating element features a dual-threaded design with different plastic materials for the threaded sections and a separating section, where the threaded parts are made from high-tensile long-fiber glass fiber composite material and the injection element from short-fiber composite material, ensuring low thermal conductivity and high tensile strength, and can be connected via a metal connecting element for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single-material insulating element is used, then the thermal insulation performance is maintained, but the load-bearing capacity is insufficient
Solution Approach 1:
The insulating element is constructed as a composite structure with a threaded part made of fiber-reinforced composite material (high tensile strength) and an injection-molded element made of different plastic material (low thermal conductivity). This composite approach allows simultaneous optimization for both load-bearing capacity and thermal insulation performance.
Solution Approach 2:
Different regions of the insulating element are made from different materials optimized for their specific functions: the threaded sections use high-strength fiber-reinforced composite for load bearing, while the separating section uses low-conductivity plastic for thermal insulation. This local differentiation resolves the contradiction between strength and versatility.
2Strength
If metal connecting elements are used, then the tensile strength is increased, but the thermal conductivity increases
Solution Approach 1:
The patent uses fiber-reinforced composite materials for the threaded parts, combining the high tensile strength needed for load-bearing applications with lower thermal conductivity compared to metal. This composite material approach allows achieving both high strength and reduced thermal energy loss.
3Strength
If high-strength materials are used throughout, then the load absorption is increased, but the thermal insulation performance deteriorates
Solution Approach 1:
The insulating element applies local quality by using high-strength fiber-reinforced composite material only in the threaded sections where mechanical loads are applied, while the separating section between threaded parts is made of low-conductivity plastic material. This spatial differentiation of material properties achieves both high load absorption and maintained thermal insulation performance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for high-load absorption, reduced thermal bridging, and cost-effective production while maintaining low thermal conductivity, enabling versatile and efficient attachment of components to building walls without thermal bridges.
Implementation Method 1
the threaded element is made from a long-fiber glass fiber composite material, whereby a particularly high tensile strength of the insulating element can be achieved, which in turn allows the absorption of particularly high loads
Implementation Method 2
the spray element can be provided with a significantly lower thermal conductivity compared to the threaded element in order to prevent the transmission of thermal energy from the anchor element to the bearing element
Implementation Method 3
the injection element can in this way have greater elasticity than the threaded element in order to allow a certain bracing of the bearing element and/or the anchor element with the insulating element
