Corner Hinge Axial Adjustment via Screw Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner bearings for windows and doors are complex and expensive, lacking a simple and cost-effective solution for adjusting the position of the sash relative to the frame to facilitate easy opening and closing.
Innovation Solution
A corner bearing system featuring a hinge pin with an inner pin, screw stop, and pin sleeve, where the screw stop is axially adjustable, allowing the pin sleeve to be displaced, enabling the adjustment of the corner bearing bush's position relative to the bearing block, thus allowing for easy pivoting and tilting of the sash by modifying the length of the inner pin through screwing or unscrewing the screw stop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complex corner bearing design is used, then the structural strength and stability are improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The hinge pin is segmented into three distinct components: an inner pin, a screw stop, and an outer pin sleeve. This segmentation allows each component to be optimized independently for strength while simplifying manufacturing processes and enabling easy adjustment of the corner bearing position.
2Reliability
If the corner bearing structure is made complex, then the reliability and functionality are improved, but the manufacturing cost increases
Solution Approach 1:
The components are nested within each other: the inner pin is inserted into the outer pin sleeve, and the screw stop threads into the pin sleeve. This nested arrangement ensures reliable mechanical connection and stable operation while keeping the overall structure compact and cost-effective to manufacture.
3Ease of operation
If the sash position adjustment mechanism is added, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The screw stop can be rotated within the pin sleeve to dynamically adjust the axial position of the hinge pin, thereby adjusting the sash position. This dynamic adjustment mechanism is simple in design but provides significant operational flexibility for installing and maintaining windows and doors.
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 solution provides a simple, inexpensive method to adjust the sash position relative to the frame, ensuring smooth operation and proper closure of windows and doors by allowing axial displacement of the pin sleeve, thereby enhancing the functionality of the corner bearing.
Implementation Method 1
the screw stop can be axially adjusted in the direction of the longitudinal extent of the hinge pin by screwing, with the result that the pin sleeve supported on the screw stop is correspondingly displaced axially
