Dual-Sealing Window Profile for Sound and Heat Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and window sealing profiles are inadequate for both soundproofing and thermal insulation, requiring multiple seals and significant installation effort, which is costly and inefficient, especially in retrofitting existing systems.
Innovation Solution
A sealing profile with two independent sealing heads, one for each joint section, arranged at an angle to create a quasi-three-chamber system, reducing sound and heat transmission effectively while being inexpensive to produce and install.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate sealing profiles are used to achieve both soundproofing and thermal insulation, then insulation performance is improved, but device complexity and installation effort increase
Solution Approach 1:
The patent combines two separate sealing profiles into a single integrated profile with dual sealing heads. The first sealing head seals the first joint section between frame and wing, while the second sealing head seals the second joint section. This merging reduces the number of components from two separate profiles to one, simplifying the overall device structure while maintaining both soundproofing and thermal insulation functions.
Solution Approach 2:
The single sealing profile is designed to perform multiple sealing functions simultaneously. The first sealing head addresses soundproofing requirements, while the second sealing head addresses thermal insulation requirements. This multi-functional design allows one component to replace what previously required two separate components, reducing installation complexity.
2Reliability
If multiple separate sealing profiles are installed to meet insulation standards, then insulation effectiveness is improved, but installation time and cost increase
Solution Approach 1:
By integrating two sealing functions into one profile, the installation process is simplified from installing two separate profiles to installing one profile. The foot area of the single profile can be fastened to the frame or wing in a single operation, and both sealing heads become operational simultaneously, reducing installation time and labor costs.
3Reliability
If separate sealing profiles are used for soundproofing and thermal insulation, then functional performance is improved, but material cost and assembly cost increase
Solution Approach 1:
The patent merges two sealing profiles into one integrated component with a single foot area for fastening. This reduces assembly complexity from attaching two separate profiles to attaching one profile, thereby reducing assembly costs while maintaining both soundproofing and thermal insulation functional performance.
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 dual-sealing profile significantly enhances sound and heat insulation with reduced material and assembly costs, making it suitable for new and existing systems with minimal installation effort, meeting current insulation standards.
Implementation Method 1
a first sealing head (121, 141.L) arranged on the foot area (11, 111) for sealing a first joint section (41) of the joint; characterized in that a second sealing head (122, 142.L) is arranged in the foot area (11, 111) for sealing a second joint section (42)

AI summary
The profile (1) has joints between a frame and a door or window leaf, and sealing heads (121, 122) e.g. lip seal (141.L) and hollow chamber seal (142.H), arranged at a base area (11) for sealing of joint portions of the joints. The sealing of the joint portions by one sealing head is independent of the sealing by the other sealing head. The sealing heads are arranged in an angle of 90 degree to each other. The sealing heads are connected with the base area over a connection section. The base area comprises an installation base (111) inserted into a recess of the frame or the leaf.
