Roof Window Frame Grooves for Low-Profile Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof windows, particularly those for conservation purposes, face challenges in meeting modern energy efficiency standards while maintaining a low profile and flexible manufacturing and installation processes, often requiring multiple levels of installation to accommodate various roofing profiles and conditions.
Innovation Solution
The roof window design features a frame with multiple receiving structures at the interior, exterior, inner, and outer sides, allowing for precise placement of auxiliary equipment such as sealing profiles, insulation, and mounting brackets, and includes interchangeable components for enhanced flexibility in manufacturing and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple receiving structures are added to the frame members, then the ease of manufacture and assembly is improved, but the device complexity increases
Solution Approach 1:
The frame members are segmented into multiple components (outer piece and inner piece) with separate receiving structures, allowing independent manufacturing and flexible assembly. The bottom frame member is divided into an outer piece and inner piece that can be manufactured separately and joined together, enabling complex receiving structures to be created from simpler components.
Solution Approach 2:
The receiving structures are designed to be multi-functional, accommodating various auxiliary equipment including sealing profiles, mounting brackets, insulation pieces, and interior lining. A single receiving structure can serve multiple purposes depending on what auxiliary equipment is installed, reducing the need for specialized structures for each function.
2Ease of manufacture
If the frame members are designed with identical cross-sections, then the ease of manufacture is improved, but the adaptability to different installation conditions decreases
Solution Approach 1:
The frame members are segmented into outer pieces and inner pieces with different cross-sectional designs. The outer piece has a first cross-section optimized for external conditions and mounting bracket engagement, while the inner piece has a second cross-section optimized for internal lining integration. This segmentation allows each part to be manufactured for its specific function while maintaining overall frame consistency.
Solution Approach 2:
Different parts of the frame members have different cross-sectional properties tailored to their specific functions. The outer portion of the frame has cross-sectional features suited for external mounting and insulation, while the inner portion has features suited for interior lining integration. This local differentiation optimizes both manufacture and adaptability.
3Shape
If the roof window is designed to maintain a low profile, then the external appearance is improved, but the ease of installation decreases
Solution Approach 1:
The frame is segmented into multiple levels with receiving structures at different heights. The first receiving structure is positioned at a first level and the second receiving structure at a second level, allowing auxiliary equipment to be installed at different vertical positions. This segmentation enables the window to maintain a low external profile while providing installation access at multiple levels.
Solution Approach 2:
The receiving structures are nested within the frame members themselves, utilizing the internal volume of the frame cross-sections. The receiving structures are formed as grooves or cavities within the outer and inner pieces, allowing auxiliary equipment to be housed within the frame's own structure rather than requiring additional external space, thus maintaining a low profile.

AI summary
In the roof window, each frame member (22) comprises a plurality of receiving structures at an interior, exterior, inner and/or outer side. The receiving structures comprise a number of grooves (25, 26, 27, 28) to interact with auxiliary equipment in an assembled condition of the frame.
