Fastening Anchor Structure for Load-Bearing Insulation Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fastening solutions for insulating materials like foamed plastic in building facades lack sufficient load-bearing capacity and require complex installations, especially for components like roller shutter boxes, which face challenges in attaching to brick or concrete facades due to the weak anchoring capabilities of existing fastening dowels and anchors.
Innovation Solution
A fastening anchor with a self-tapping thread and a bolt receptacle that allows for secure anchoring in insulating materials, enabling the attachment of insulating elements like winding shaft housings to building walls without pre-drilling, using a multi-stepped head and a bolt receptacle that accommodates fastening bolts at various angles for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fastening dowels are used to attach components to insulating materials, then installation is simplified, but load-bearing capacity is insufficient
Solution Approach 1:
The fastening anchor is divided into two functional parts: an anchor element for insertion and anchoring in the insulating material, and a separate bolt receptacle for receiving the fastening bolt. This segmentation allows each part to be optimized independently - the anchor element for easy insertion and the bolt receptacle for strong mechanical connection.
Solution Approach 2:
The bolt receptacle is positioned offset from the anchor element's central axis, creating a lever arm that transforms the linear anchoring force into enhanced mechanical strength. The fastening bolt extends through the bolt receptacle at an angle, utilizing spatial dimensionality to improve load-bearing capacity beyond what a simple straight-through anchor could achieve.
2Adaptability or versatility
If L-shaped support brackets are used to attach roller shutter boxes, then attachment to building structures is enabled, but device complexity increases
Solution Approach 1:
The fastening anchor serves multiple functions in a single integrated component: it anchors the insulating material, provides a mounting point for the fastening bolt, and enables attachment to various building structures. This eliminates the need for separate L-shaped support brackets and simplifies the overall assembly.
Solution Approach 2:
The anchor element and bolt receptacle are combined into a single fastening anchor component that is directly integrated with or attached to the roller shutter box. This merging eliminates the need for separate support brackets and reduces the number of parts and installation steps.
3Strength
If self-tapping threads with deep pitch are used in insulating materials, then anchoring is achieved, but installation time increases
Solution Approach 1:
The anchor element is pre-formed with the self-tapping thread geometry during manufacturing. The deep-pitch threading is already configured on the anchor element before installation, eliminating the need for progressive thread formation during installation and reducing installation time while maintaining anchoring strength.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The proposed fastening anchor provides secure anchoring in low-strength insulating materials, allowing for easy installation and increased load-bearing capacity, facilitating the attachment of insulating components to building structures without pre-drilling, thus simplifying the installation process and enhancing the structural integrity of insulating elements.
Implementation Method 1
a self-tapping thread with a particularly deep thread pitch and a dowel head, which comes to a stop on the insulating material element after the dowel has been screwed into the pre-drilled insulating material element
