Hinge Locator Ramp Guides Sash Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of hinge mechanisms in fenestration units is labor-intensive due to the need for correct alignment and support of heavy sash windows, often requiring additional labor to prevent misalignment and ensure proper sealing, especially in large units or those with additional weight from glazing units.
Innovation Solution
A hinge locator assembly with a ramped body and integral retaining formation that guides and secures the hinge mechanism within the outer frame, minimizing user intervention by ensuring correct alignment and reducing the number of parts needed, while allowing for easy fastening and reduced labor requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the sash is supported manually during hinge mechanism installation, then correct positioning and alignment can be achieved, but additional labor is required and the process becomes cumbersome
Solution Approach 1:
The patent introduces a positioning device as an intermediary tool between the installer and the hinge mechanism. This device includes a support member that temporarily holds the hinge mechanism in the correct position and a positioning member that aligns it with the outer frame. The positioning device acts as a mediator that eliminates the need for manual support while ensuring precise alignment, thereby resolving the contradiction between alignment precision and installation efficiency.
Solution Approach 2:
The positioning device is designed to be installed in advance on the outer frame before the hinge mechanism is attached. The support member and positioning member are pre-positioned to define the correct location and orientation. This preliminary action allows the hinge mechanism to be quickly attached without requiring manual support during alignment, improving installation efficiency while maintaining precision.
2Ease of operation
If the sash weight is fully supported by the outer frame during closure, then the fastening process can be simplified, but correct alignment of the hinge mechanism cannot be ensured
Solution Approach 1:
The positioning device serves as an intermediary that maintains correct alignment independently of the sash weight. The support member holds the hinge mechanism in position while the positioning member ensures alignment with the outer frame. This allows the sash to be supported by the outer frame during closure without compromising alignment precision, as the positioning device maintains the correct position throughout the process.
Solution Approach 2:
The positioning device provides prior cushioning by pre-positioning the hinge mechanism in the correct location and orientation before the closure process begins. The support member and positioning member are installed in advance to prevent misalignment, allowing the sash weight to be fully supported by the outer frame during closure without risking alignment errors.
3Manufacturing precision
If multiple installers are used to support heavy sash windows, then correct positioning can be maintained, but labor costs and installation time increase
Solution Approach 1:
The positioning device acts as an intermediary tool that replaces the need for multiple installers to manually support and align the hinge mechanism. The support member and positioning member automatically maintain correct positioning and alignment, allowing a single installer to perform the task efficiently. This eliminates the need for additional labor while preserving positioning accuracy.
Solution Approach 2:
The positioning device enables self-service by providing automatic positioning and alignment capabilities. The support member holds the hinge mechanism in the correct position while the positioning member aligns it with the outer frame without requiring manual intervention from multiple installers. This self-positioning capability reduces labor quantity while maintaining positioning accuracy.
