Foam Rubber Attachment Device for Sealing Profile Clamp Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deformation of sealing profiles caused by clamp mounts reduces their sealing effectiveness, leading to air leakage and increased energy consumption for temperature control in buildings.
Innovation Solution
An attachment device in the form of a strip with a recess and tapering lips that accommodates the clamping flange, made from dimensionally stable foam rubber, which fills the opening formed by the clamp mount without impairing closability and provides a visual check for proper tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a clamp mount is used to mount sunshades without drilling holes, then the ease of installation is improved, but the sealing effect of the sealing profile deteriorates due to deformation caused by clamping force
Solution Approach 1:
An attachment device made of elastic material (such as foam rubber) is introduced as an intermediary between the clamping flange and the sealing profile. This attachment device absorbs the clamping force while maintaining the sealing effect, allowing the clamp mount to be installed without drilling holes while preserving the sealing performance of the sealing profile.
2Adaptability or versatility
If the attachment device is made from elastic material like foam rubber, then the adaptability to tolerances and long-term stability are improved, but the manufacturing complexity increases
Solution Approach 1:
By selecting elastic materials with specific physical parameters (hardness, density, thickness) that are readily available and inexpensive, the attachment device achieves adaptability to tolerances and long-term stability while maintaining simple manufacturing processes through extrusion.
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
Enhances the insulating effect by reducing air exchange between indoors and outdoors, lowering energy consumption in both cold and warm climates by maintaining a secure seal over time.
Implementation Method 1
The attachment device is made of a material, for example foam rubber, which is readily available, inexpensive, extrudable and dimensionally stable, and also has elastic properties. Due to the elastic properties, the attachment device has good long-term stability and is insensitive to tolerances.

AI summary
The invention relates to an attachment device for sealing an opening (20) created by a first clamping flange (11) of a clamping bracket (10) on a sealing profile (21). According to the invention, the attachment device (1) is designed in a band shape with a sash side (3) and an opposite frame side (2), wherein the sash side (3) comprises a recess (4) whose dimensions are selected such that the first clamping flange (11) of the clamping bracket (10) can be received therein, as well as first and second lips (5, 5') that delimit the recess (4) on two opposite sides and which taper towards their end opposite the recess (4) between the sash side (3) and the frame side (2). This allows the openings in the sealing profile caused by pressing in the clamping bracket to be filled and sealed by the attachment device without impairing the window's ability to be closed.
