Elastic Sealing Strip for Insulating Layer Connection Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection profiles for insulating material layers with plastered components, such as window or door frames, are complex and difficult to handle, leading to potential cracks and cold bridges due to irregular gaps and inefficient sealing.
Innovation Solution
A connection profile featuring an elastic or expanding sealing strip that is inserted into a U-shaped receiving space after the base profile is attached, providing a seamless seal and accommodating relative movements, with optional elastic sealing elements to fill gaps between the profile and insulating material layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional connection profile with multiple components is used, then sealing capability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines the sealing strip, fastening leg, and cover strip into a single integrated outer profile component. This merging eliminates the need for multiple separate components while maintaining the sealing function, thereby reducing device complexity and improving ease of operation without sacrificing sealing capability.
Solution Approach 2:
The outer profile serves multiple functions simultaneously: it provides sealing through the elastic sealing strip, structural support through the U-shaped cross-section, and fastening through the integrated fastening leg. This multi-functionality reduces the number of components needed while maintaining comprehensive sealing and structural performance.
2Reliability
If an elastic sealing strip is inserted into the receiving space, then sealing capability and adaptability are improved, but manufacturing precision requirements worsen
Solution Approach 1:
The patent uses an elastic sealing strip that changes its physical state from a compressed condition during insertion to an expanded condition during service. This parameter change allows the sealing strip to adapt to variations in the receiving space dimensions, compensating for manufacturing tolerances and reducing the precision required during installation.
Solution Approach 2:
The elastic sealing strip functions as a flexible element that can deform to fit into the U-shaped receiving space formed by the base profile and component. This flexibility allows the sealing strip to accommodate dimensional variations and irregularities in the receiving space without requiring high manufacturing precision.
3Ease of operation
If the outer profile is inserted into the groove-shaped receptacle, then ease of operation is improved, but device complexity worsens
Solution Approach 1:
The outer profile is divided into distinct functional segments: the elastic sealing strip for sealing, the fastening leg for mechanical attachment, and the cover strip for aesthetic coverage. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity of the assembly process.
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
The solution achieves a permanent seal between the facade and components, compensates for relative movements, and simplifies the assembly and production process, reducing waste and avoiding butt joints, while effectively preventing leaks and thermal bridges.
Implementation Method 1
the connection profile has an elastic sealing strip or an expanding sealing strip, which can be inserted into the U-shaped receiving space after the base profile has been attached to the component and, after it has been unfolded, rests sealingly on the component and on the retaining web of the base profile
Implementation Method 2
the connection profile has an elastic sealing strip or an expanding sealing strip, which can be inserted into the U-shaped receiving space after the base profile has been attached to the component and, after it has been unfolded, rests sealingly on the component and on the retaining web of the base profile
Implementation Method 3
the fastening leg and/or the spring element are designed to be elastic due to the choice of material or shape, in order to react correspondingly elastically to relative movements between the components

AI summary
The profile (1) has a base profile (2) fastened to door- or window frames (10) including a mounting leg (19) and a base part (30). An elastic deformable sealing lip (34) is arranged between the mounting leg and front and/or side surfaces (35, 36) of an insulating layer (11), where the front and/or side surfaces faces toward the profile. The sealing lip closes gap between the profile and insulating layer, and is integrated in the front and/or side surfaces. The base profile includes a holding bar (5) with a holding edge (16) that is projected in direction of the frames.
