Two-Part Post Connector with Adhesive Recesses for Window Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door construction methods require additional mechanical seals and fastening screws to prevent dirt and moisture penetration, increasing costs and assembly complexity, especially when using adhesive connections between post connectors and frame profiles.
Innovation Solution
A two-part post connector design with latching elements and recesses that allow for an adhesive bond without the need for screws, using groove-shaped and areal recesses that are filled with a hardening adhesive, eliminating the need for separate mechanical seals and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical seals and fastening screws are used to prevent dirt and moisture penetration, then sealing reliability is improved, but device complexity and assembly cost increase
Solution Approach 1:
The patent combines the sealing function and mechanical connection function into a single integrated post connector structure. The post connector simultaneously provides mechanical fastening through its body structure and sealing through integrated sealing elements, eliminating the need for separate mechanical seals and reducing assembly complexity while maintaining sealing reliability
Solution Approach 2:
The post connector is designed as a multi-functional component that performs multiple functions: mechanical fastening of the post to the frame profile, sealing against dirt and moisture penetration, and providing structural support. This universal component replaces what would traditionally require multiple separate components including mechanical seals and fastening screws
2Reliability
If additional mechanical seals and fastening screws are used, then sealing reliability is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the sealing function and mechanical connection function into a single integrated post connector structure. The post connector simultaneously provides mechanical fastening through its body structure and sealing through integrated sealing elements, eliminating the need for separate mechanical seals and reducing assembly complexity while maintaining sealing reliability
Solution Approach 2:
The post connector is designed as a multi-functional component that performs multiple functions: mechanical fastening of the post to the frame profile, sealing against dirt and moisture penetration, and providing structural support. This universal component replaces what would traditionally require multiple separate components including mechanical seals and fastening screws
3Ease of operation
If a two-part post connector with adhesive connection is used, then assembly simplicity is improved, but sealing reliability may worsen without additional mechanical seals
Solution Approach 1:
The patent combines the sealing function and mechanical connection function into a single integrated post connector structure. The post connector simultaneously provides mechanical fastening through its body structure and sealing through integrated sealing elements, eliminating the need for separate mechanical seals and reducing assembly complexity while maintaining sealing reliability
Solution Approach 2:
The patent introduces an adhesive as an intermediary substance to create a reliable seal and mechanical bond between the post connector parts and the frame profile. The adhesive fills gaps and creates a weather-tight seal, compensating for the simplified mechanical connection and ensuring sealing reliability without requiring additional mechanical seals

AI summary
In a method for connecting a mullion (9) to a hollow profile and a frame profile (8) of a window or door using a mullion connector (1) comprising a base part (2) attachable to the frame profile (8) and a mounting part (3) attachable to the base part (2), the base part (2) is connected to the frame profile (8), the mounting part (3) to the mullion (9), and both parts are connected to each other by snapping. Recesses (15, 37) are provided on the upper and lower surfaces of the base part (2) and on the upper surface of the mounting part (3), which, in the assembled state of the connection arrangement, are interconnected via at least one connecting channel (19, 20; 23, 24) formed in the base part (2) and in the mounting part (3).The open sides of the recesses (15, 37) are covered on the underside of the base part (2) by the mounting surface of the frame profile (8), on the top side of the base part (2) by surfaces on the attached mounting part (3), and on the top side of the latter by surfaces on the facing end region of the post (9). All recesses (15, 37) are filled with a curing liquid adhesive. The invention also relates to a connection arrangement between a frame profile (8) and a post (9).
