Concealed Window Corner Bearing Plug Connection Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner bearings for windows and doors suffer from instability due to the large amount of play required for tilting movements, which limits their ability to support heavy loads, especially in large-area, multi-glazed applications.
Innovation Solution
A corner bearing design featuring a plug connection between the frame-side and sash-side fitting parts, with a bearing plate and base plate connected via bolts and recesses, allowing for easy assembly and high stability, and incorporating conical sections and adjustment devices for precise alignment and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bolts with large play are used to enable tilting movement, then the tilting function is achieved, but the stability of the corner bearing deteriorates
Solution Approach 1:
The corner bearing is divided into functionally independent segments: the tilting bearing (enabling tilting movement between flange element and support element) is separated from the plug connection (providing stability between bearing plate and base plate). This segmentation allows each component to fulfill its specific function without compromising the other - the tilting bearing provides operational freedom while the plug connection ensures structural stability.
Solution Approach 2:
The tilting bearing acts as an intermediary element between the flange element and support element, enabling controlled tilting movement while the plug connection serves as an intermediary between the bearing plate and base plate, providing firm connection. These intermediary components mediate between the conflicting requirements of movement and stability.
2Stability of the object's composition
If a firm connection between bearing plate and base plate is made, then stability is improved, but assembly complexity increases
Solution Approach 1:
The plug connection between the bearing plate and base plate is designed to be pre-assembled on the wing side, with the bearing plate already fixed to the wing and the plug connection components positioned in advance. This preliminary action simplifies the final assembly process, as the firm connection is already prepared and only requires insertion into the frame, reducing overall assembly complexity while maintaining high stability.
3Force
If the corner bearing is designed for heavy load support, then load capacity is improved, but the structure becomes more complex
Solution Approach 1:
The plug connection merges the bearing plate and base plate into a firmly connected unit that can support heavy loads. By combining these components through a robust plug connection design (with bolt and recess engagement), the structure achieves high load capacity without requiring additional complex support mechanisms, as the plug connection itself provides both structural integrity and load-bearing capability.

AI summary
The bearing (1) has support and control guides (6, 7) including vertical bearing shafts for attachment at frame-sided and wing-sided fitting parts (4, 5). The wing-sided fitting part includes a flange element (8) for connection with a wing, and a carrier element (9) for connection with the guides. A tilted bearing (15) is arranged between the flange element and the carrier element. The frame-sided fitting part includes a bearing plate (11) for connection with the guides, and a base plate (10) for connection with a frame (2). The base and bearing plates are connected by a plug connection (12).
