Window Fitting Seal Integration for Structural Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windows and doors with glass panes often rely solely on the frame for support and sealing, leading to inadequate structural strength and unreliable moisture sealing due to gaps between the fitting structure and seals.
Innovation Solution
Incorporating a glass fastening device on the second hinge part outside the frame, with a holding profile matching the second hinge part's contour, and a seal receiving device that ensures continuous sealing without interruptions, enhancing structural support and aesthetics by integrating the seal into the hardware construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the glass pane is held only by the frame, then the frame structure is simple, but the overall structural strength is insufficient
Solution Approach 1:
The patent merges the glass holding function with the hardware construction (hinge parts). The second hinge part is designed with a contour that matches the holding profile, and the band parts are connected to both the frame and the glass pane, creating a combined support system that increases structural strength without requiring a completely separate holding mechanism
2Reliability
If the seal is located in the area of the window or door opening, then the sealing is provided, but there is a gap between the fitting structure and the seal allowing moisture penetration
Solution Approach 1:
The patent combines the sealing function with the hardware construction by providing a receiving device for the seal on the second hinge part. This integration eliminates gaps between the fitting structure and the seal, as the seal runs continuously through the hardware construction area without interruptions or gaps that would allow moisture penetration
3Reliability
If the seal is squeezed in the area of the hardware construction or interrupted, then the hardware construction is compact, but the sealing effect becomes unreliable
Solution Approach 1:
The patent introduces a receiving device designed as a groove on the second hinge part that acts as an intermediary structure. This groove receives and accommodates the seal, allowing the seal to run continuously and uninterruptedly through the hardware construction area without being squeezed or compressed, thereby maintaining reliable sealing while preserving hardware compactness

AI summary
A fitting, especially for windows and/or doors, comprises two strips. The first strip is connected to a frame and the second strip is connected to a casement. At least one strip has a receiving section for accommodating a seal (23), located on the first strip. The receiving section is parallel to the longitudinal axis of the fitting, and has a longitudinal groove for holding the seal. The outer glass fixing unit has a receiving groove for eg a sheet of glass. The receiving groove opening and the longitudinal groove opening are at right angles to one another.
