Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall anchoring systems in insulated outer building walls, particularly in cavity walls, face challenges such as inaccurate insulation mounting, risk of insulation damage, thermal bridging, and increased installation time and costs due to the need for numerous wall ties.
Innovation Solution
The introduction of an anchoring rail profile with a unique design that secures the insulation layer and anchors the outer wall, minimizing thermal bridges and reducing the number of wall ties required, while allowing for easy and fast installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If protruding wall ties are used to connect inner and outer walls, then structural integrity is improved, but thermal bridging increases and insulation mounting precision deteriorates
Solution Approach 1:
The wall anchoring system is divided into separate functional components: insulation support elements that hold insulation boards in place, and wall anchoring elements that connect inner and outer walls. This segmentation allows each component to perform its specific function without compromising thermal insulation, as the anchoring elements can be positioned to minimize thermal bridges while the support elements ensure precise insulation mounting.
Solution Approach 2:
The patent introduces intermediary components such as insulation support elements and mounting brackets that act as mediators between the insulation layer and the wall structure. These intermediaries allow the insulation to be securely mounted without requiring protruding wall ties that would create thermal bridges, thus resolving the contradiction between structural integrity and thermal performance.
2Strength
If numerous wall ties are used to withstand wind load, then structural strength is improved, but installation time and costs increase
Solution Approach 1:
The insulation support elements are designed to be pre-installed on the inner wall structure before the insulation boards are positioned. This preliminary action allows the insulation to be quickly snapped into place without requiring subsequent adjustments or additional fastening operations, significantly reducing installation time while maintaining the structural strength needed to withstand wind loads.
Solution Approach 2:
The patent combines multiple functions into integrated components: the insulation support elements simultaneously provide structural support, insulation mounting, and positioning functions. This merging of functions eliminates the need for separate wall ties and mounting brackets, reducing the total number of components and simplifying the installation process while maintaining adequate wind load resistance.
3Adaptability or versatility
If wall ties are bent to fit between brick layers, then adaptability to construction variations is improved, but wall tie strength is reduced
Solution Approach 1:
Instead of bending the wall ties to fit the brick layers, the patent inverts the approach by designing rigid wall ties with standardized dimensions and providing adjustable mounting elements that adapt to construction variations. The mounting brackets and support elements are designed to accommodate different brick layer configurations without requiring deformation of the load-bearing wall tie components, thus maintaining their full strength while achieving adaptability.
