Corner Hinge Support Element Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner bearings for windows and French doors face challenges in supporting high sash weights while maintaining low production costs, particularly for small and light sashes, as high material thickness is both costly and unstable when not needed.
Innovation Solution
A corner bearing design featuring a support element with a support plate and housing that can be used optionally, where the support plate rests against a screw-on plate and the housing encompasses the horizontal bearing, allowing for increased stability when needed and cost-effective manufacturing by omitting the support element for lighter loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If high material thickness is used in the corner bearing, then the stability and load-bearing capacity are improved, but the production cost increases and the design becomes disruptive for small sashes
Solution Approach 1:
The corner bearing is divided into two functional segments: a base element that is always present, and an optional support element that can be attached when high sash weights require additional support. This segmentation allows the bearing to provide high stability for heavy sashes while maintaining low production costs for light sashes by omitting the support element, directly resolving the contradiction between stability and manufacturing cost.
Solution Approach 2:
The corner bearing transitions from a static, fixed-design structure to a dynamic, adaptable configuration. The support element can be selectively attached or removed based on the specific application requirements (sash weight), allowing the system to optimize its structural properties for different operating conditions. This dynamic adaptability enables the bearing to achieve high stability when needed while avoiding unnecessary costs when not required.
2Strength
If high material thickness is used in the corner bearing, then the load-bearing capacity is improved, but the design becomes complex and costly for small sashes
Solution Approach 1:
The bearing structure is segmented into essential components (base element with horizontal and vertical bearings) and optional components (support element with support plate and support housing). This segmentation allows the design to maintain simplicity for small sashes while providing enhanced load-bearing capacity when the support element is attached for heavy sashes, resolving the contradiction between strength and design complexity.
Solution Approach 2:
The support element is designed with localized reinforcement features including a support plate that rests against the screw-on plate and a support housing that encompasses the horizontal bearing. These local quality enhancements provide targeted strength where needed without unnecessarily complicating the entire bearing design, allowing the system to achieve high load-bearing capacity only when required by the application.
3Stability of the object's composition
If a support element is always included in the corner bearing, then the stability for high sash weights is improved, but the production cost increases for small sashes
Solution Approach 1:
The corner bearing is designed with a separable support element that can be selectively included or excluded. This segmentation allows the system to optimize material quantity based on actual needs: the support element is attached only when high sash weights require additional stability, thereby avoiding unnecessary material consumption and production costs for small, light sashes while maintaining high stability when required.
Solution Approach 2:
The configuration of the corner bearing dynamically adapts to the specific application requirements. The support element can be selectively attached or removed based on the sash weight and stability needs, allowing the system to optimize material quantity used. This dynamic approach ensures that material resources are allocated only where necessary, resolving the contradiction between stability and material quantity.

AI summary
The corner bearing (7) comprises a base element (14) arranged on a horizontal bearing (10) for mounting a bearing bolt (12) of a vertical bearing (11). The mounting plate (16) is formed with a support flange for support on the window. A supporting element (15) is provided for supporting the fixing plate of the base element and the horizontal bearing.
