Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facade attachment methods create thermal bridges and are complex and costly for renovating insulated buildings, as they require removing and replacing insulation layers to attach consoles, and are not adaptable to varying insulation thicknesses.
Innovation Solution
A console with a fiber-reinforced plastic rod featuring a cone or wedge tip and rejuvenated diameter section for anchoring in boreholes, allowing direct attachment through insulation layers, combined with an adjustable headpiece for varying lengths and thermal decoupling, using a mortar cartridge for secure anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional metal fasteners are used to attach facade elements to insulated walls, then mechanical fastening is achieved, but thermal bridges are created
Solution Approach 1:
The patent employs composite materials by using a plastic anchor body combined with a metal reinforcement cage and chemical anchoring agent. The plastic material provides thermal insulation to eliminate thermal bridges, while the metal cage and chemical mortar ensure mechanical anchoring strength. This composite approach resolves the contradiction between mechanical strength and thermal insulation.
Solution Approach 2:
The plastic anchor body acts as an intermediary between the metal reinforcement cage and the wall substrate. It provides thermal decoupling to prevent thermal bridges while transmitting mechanical loads through the chemical anchoring system. The plastic material mediates between the need for strong mechanical fastening and the requirement to eliminate thermal conduction paths.
2Reliability
If insulation layers are removed to attach conventional brackets, then direct wall attachment is achieved, but renovation complexity and cost increase
Solution Approach 1:
The anchor system is designed to be self-installing through the insulation layer without requiring its removal. The drill-bit-integrated anchor delivers itself through the insulation to the wall substrate, and the expansion mechanism automatically secures it in place. This self-service capability eliminates the need for complex manual installation procedures and insulation removal/replacement.
Solution Approach 2:
The anchor system segments the attachment function into distinct components: a drill-bit for penetration, a plastic anchor body for thermal decoupling and expansion, a metal reinforcement cage for structural strength, and chemical mortar for bonding. This segmentation allows each component to perform its specific function efficiently, simplifying the overall installation process while maintaining attachment reliability.
3Ease of manufacture
If fixed-length brackets are used, then manufacturing is simplified, but adaptability to varying insulation thicknesses is reduced
Solution Approach 1:
The anchor system incorporates dynamic adjustment capabilities through variable-length metal reinforcement cages and adjustable expansion mechanisms. The cages can be supplied in different lengths to match various insulation thicknesses, and the expansion mechanism can adapt to different wall depths. This dynamic adaptability allows a single basic anchor design to serve multiple insulation thickness requirements.
Solution Approach 2:
The basic anchor design serves multiple functions: it provides thermal decoupling, mechanical anchoring, and adaptable length configuration. By making the core anchor body universal and only varying the cage length, the system achieves multi-functionality across different insulation thicknesses while maintaining manufacturing efficiency through standardized production of the main anchor component.

Function Achieved in This Case
The solution eliminates thermal bridges, enables efficient attachment to insulated facades without removing insulation, and allows for adjustable lengths to accommodate different insulation thicknesses, reducing renovation complexity and costs.
Implementation Method 1
A console with a fiber-reinforced plastic rod featuring a cone or wedge tip and rejuvenated diameter section for anchoring in boreholes
Implementation Method 2
The inserted rod is made of plastic in which a fiber reinforcement, preferably consisting of continuous fibers, is embedded
Implementation Method 3
The inserted rod is made of plastic in which a fiber reinforcement, preferably consisting of continuous fibers, is embedded. Furthermore, the front insert, which serves for anchoring in a wall, has at least one intermediate section with a reduced diameter. The resulting undercut allows the rod to be securely anchored in a borehole in a building wall using mortar.
Implementation Method 4
These objectives are achieved by the subject matter according to claim 1. The bracket according to the invention is characterized in that the inserted rod is made of plastic in which a fiber reinforcement, preferably consisting of continuous fibers, is embedded
