Concealed Corner Support Adjusting Contact Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner bearings for windows and balcony doors struggle to adjust contact pressure without weakening the bearing or changing the sash's position, as adjustability often compromises the structural integrity and stability of the pivot point.
Innovation Solution
The wing-side fitting unit features a base part connected to the control and support links with a common axis of rotation, allowing independent adjustment of the support part relative to the base part using an adjusting device, such as an eccentric, to separate adjustability from the pivot axes and maintain bearing strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pin is made eccentrically adjustable to change the pivot point position, then the adaptability of the sash position is improved, but the strength and reliability of the connection between the fitting unit and the sash is weakened
Solution Approach 1:
The fitting unit is divided into a base part connected to the links and a support part connected to the sash, allowing independent adjustment of the support part without affecting the structural integrity of the base part and its connection to the control and support links
2Adaptability or versatility
If the pin is made adjustable to change the pivot point, then the adaptability is improved, but the reliability of the bearing connection is worsened due to potential inadvertent adjustment
Solution Approach 1:
The adjustment function is separated from the bearing connection by dividing the fitting unit into base part and support part, so that the adjustable support part does not compromise the reliable bearing connection in the base part
Solution Approach 2:
The common axis of rotation acts as an intermediary element that allows the support part to be adjusted independently while maintaining a stable, non-adjustable connection between the base part and the links
3Volume of moving object
If the fitting units and links are arranged in a sandwich-like manner for compactness, then the volume is reduced, but the adjustability compromises the structural integrity
Solution Approach 1:
The fitting unit is segmented into base part and support part, allowing the compact sandwich-like arrangement to be maintained while the support part can be adjusted independently without compromising the structural integrity of the overall assembly
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the resistance to opening forces and maintains structural integrity by keeping the adjustability of the wing and pivot axes independent, allowing for adjustable contact pressure without compromising the bearing's stability, and facilitates easy adjustment with a tool-accessible eccentric mechanism.
Implementation Method 1
an adjusting device for adjusting the support part relative to the base part has an eccentric

AI summary
The bearing has support arm (6) and a hinge rod (7) that are connected with the frame side and wing-side fitting units (4,5) in the horizontal pivot axis. A base portion (11) of wing-side fitting unit is connected to the hinge rod and the support arm. A support portion (12) is connected with a wing (2). The base portion and support portion are provided with common axis (10), and the position of the support portion on the base portion is adjustable.
