Window Frame Sealing Profile Corner Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door frame sealing profiles face challenges in the corner area, including buckling, damage during closure, and limited height due to curved sections, which affect installation and thermal insulation.
Innovation Solution
A sealing profile is cut and angled in the corner area to allow for a smaller bend radius, avoiding protrusion and using a corner element for precise alignment and pre-fixing, with a hollow chamber design and elastic materials for flexibility and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the sealing profile is guided over a corner element with an arcuate section, then the sealing profile can follow the corner contour, but the sealing profile buckles severely and interferes with window or door leaf closing
Solution Approach 1:
The sealing profile is segmented by making an incision in the corner area, dividing it into sections that can be independently positioned. This allows the profile to follow the corner contour while maintaining stability, as the segmented sections can be precisely aligned using the corner element with alignment features.
Solution Approach 2:
The corner element serves as an intermediary component between the sealing profile and the frame corner. It provides a structured interface with alignment features that guide the sealing profile sections into correct positioning, enabling contour following without buckling.
2Strength
If the sealing profile is bent with a large radius in the corner area, then the profile maintains structural integrity, but the overall height is limited and protrusion occurs
Solution Approach 1:
By incising the sealing profile in the corner area, the profile is divided into segments that can be independently positioned at different heights. This segmentation allows the profile to achieve greater overall height without requiring a large bend radius, maintaining structural integrity while enabling vertical adjustment.
Solution Approach 2:
The solution transitions from a two-dimensional bend radius problem to a three-dimensional arrangement by incising the profile and using vertical positioning of segmented sections. This allows height adjustment without being constrained by the bend radius in the horizontal plane.
3Ease of manufacture
If the sealing profile is cut and bent in the corner area, then installation becomes easier, but material stresses and buckling occur
Solution Approach 1:
The corner element acts as a mediator that receives the cut and bent sealing profile sections, providing support and alignment features. This intermediary structure distributes and reduces material stresses while maintaining installation ease, as the corner element bears part of the mechanical load.
Solution Approach 2:
The corner element is pre-equipped with alignment features and positioning structures before the sealing profile is installed. This preliminary preparation guides the installation process, reducing the need for complex bending operations and minimizing material stresses during installation.
4Stability of the object's composition
If a solid material sealing profile is used, then the profile maintains shape, but flexibility and adaptability in the corner area are reduced
Solution Approach 1:
The solid material sealing profile is incised in the corner area, creating segmented sections that can be independently positioned. This segmentation provides flexibility and adaptability while the solid material between incisions maintains shape stability and structural integrity.

AI summary
A frame (1) or T-joint (1'), in particular a frame for a window or door, comprises a sealing profile (6) which is fixed to a frame profile (2, 2', 3, 3') by a base (60), wherein the sealing profile (6) is arranged in a central region of the frame profile (2, 2', 3, 3'), and wherein the sealing profile (6) is cut into a corner region of the frame (1) or T-joint (1') on the outside and aligned at an angle. The invention further relates to a method for assembling a frame (1) or a T-joint (1') in which a sealing profile is cut into and folded, and a corner element is inserted into the cut section. This facilitates assembly and enables high thermal insulation.
