Roof Window Sash Installation Component With Three Support Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof windows, particularly those for conservation purposes, face challenges in installation ease, thermal efficiency, and environmental impact, especially when installed on inclined roof surfaces with flat roofing materials, requiring improved fitting and operating assemblies that minimize protrusion and enhance sustainability.
Innovation Solution
A roof window design featuring a hinge assembly with a coupling unit and sash installation component that includes three distinct support surfaces and a frame engagement portion shaped to facilitate a step-wise installation process, allowing the frame to be fastened independently of the sash, and using materials like polymeric foam or cardboard for stability and reusability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the frame and sash are installed as a single unit, then the installation process is simpler, but the sash cannot be independently positioned and adjusted during installation
Solution Approach 1:
The invention divides the window assembly into separate frame and sash components that can be installed independently. The frame is first installed and secured to the roof structure, then the sash is separately positioned and attached to the frame through coupling plates and hinge assemblies, enabling staged installation and adjustment.
Solution Approach 2:
The frame is installed and secured to the roof structure before the sash is attached. This preliminary installation of the frame provides a stable base and allows for proper positioning and alignment of the sash in subsequent steps, ensuring correct installation sequence.
2Device complexity
If traditional installation methods are used without support components, then the device structure is simpler, but the sash lacks stability during the engagement process
Solution Approach 1:
A sash installation component acts as an intermediary between the sash and the installer. This component includes support surfaces that contact and stabilize the sash at specific positions (side coupling position, top coupling position, service position) during the engagement process, providing necessary stability without requiring complex temporary support structures.
3Ease of manufacture
If the sash installation component uses disposable materials, then the manufacturing cost is lower, but the environmental impact increases
Solution Approach 1:
The sash installation component is designed to be reusable rather than disposable. After the sash is properly installed and secured, the installation component can be removed and reused for subsequent installation projects, reducing waste and environmental impact while maintaining manufacturing simplicity through the use of common materials like polymeric foam or cardboard.
