Window Frame Profile Assembly with Recessed Connection Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of frame profile assemblies for windows or doors is complex and does not ensure a secure seal between the interior and exterior, particularly in the connection area of the dividing profile on the base frame profile.
Innovation Solution
A frame profile assembly design where the connection sealing body is arranged in a recess completely in the outer area, allowing for a simple geometry and eliminating the need to modify the base profile, with the sealing body fully contained within the recess, ensuring a secure seal without protruding into the parting plane between interior and exterior areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the connection sealing body is arranged in a recess completely in the outer area, then the assembly is simplified and production costs are reduced, but the sealing effect between interior and exterior must be maintained
Solution Approach 1:
The sealing system is segmented into multiple sealing bodies: a base profile center seal for the main sealing function and a connecting sealing body for the connection area. This segmentation allows each sealing body to be optimized independently and simplifies the overall assembly process while maintaining reliable sealing throughout.
Solution Approach 2:
The connecting sealing body is extracted and placed exclusively in the outer area within a recess, separate from the base profile center seal. This extraction simplifies the design by eliminating the need for the sealing body to protrude into the parting plane, thereby simplifying assembly while maintaining sealing effectiveness through the recessed positioning.
2Ease of manufacture
If the sealing body is arranged completely in the outer area within a recess, then the geometry becomes uncomplicated and production costs are reduced, but the sealing continuity at the transition area must be ensured
Solution Approach 1:
The recess is pre-formed in the dividing profile at the connection area, preparing the space for the connecting sealing body before assembly. This preliminary action simplifies manufacturing by defining the sealing body's position in advance and ensures proper sealing continuity without requiring complex geometries or additional modifications during assembly.
Solution Approach 2:
The connecting sealing body acts as an intermediary element between the base profile center seal and the outer sealing system. It bridges the transition area by being positioned in the recess, ensuring sealing continuity while maintaining a simple geometry that is easy to manufacture.
3Ease of operation
If the base profile center seal is not prepared in the connection area, then assembly is simplified, but the sealing effect at the transition area must be maintained
Solution Approach 1:
The connecting sealing body is extracted from the base profile center seal and positioned independently in the recess of the dividing profile. This extraction eliminates the need to prepare or modify the base profile center seal in the connection area, simplifying assembly while maintaining sealing effectiveness through the separate connecting sealing body.

AI summary
A frame profile assembly (1) is an integral part of a window or door frame. The assembly (1) has a base frame profile (2), a dividing profile (3) configured as a post or cross-bar, and a connecting device (11) for attaching the dividing profile (3) to the base frame profile (2) while overlapping a base profile center seal (4) in sections. The base frame profile (2) has a circumferential center seal (4) which seals an interior region (5) from an exterior region (6) that is exposed to the weather when the frame is installed. A folded base of a profile cross-section of the base frame profile (2) is disposed in the exterior region (6). The connecting device (11) comprises a connecting seal body (12), which is disposed in the folded base and, in case of an installed assembly, is disposed in a recess (19) positioned completely in the exterior region (6) in a sealing manner. The result is a frame profile assembly, the simplified installation of which is ensured while simultaneously providing a secure seal between the interior region and the exterior region even in the connecting regions of the dividing profile at the base frame profile.
