Roof Window Installation Aid with Reduced Thickness Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation aids for mounting roof windows often require additional insulating and weather-proofing due to their thickness, which can elevate the window above the roofing plane, and pose challenges in correctly positioning the window frame within the aid.
Innovation Solution
A plate portion with reduced material thickness sections for accommodating mounting brackets, providing guidance through visual or tactile indications, and made from dimensionally stable materials like polymers and wood-based composites, allowing the installation aid to be flush with the roof surface and facilitating easier window frame positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the installation aid uses sufficient material thickness to provide dimensional stability, then the structural strength is improved, but the window frame is elevated above the roofing plane requiring additional insulating and weather-proofing
Solution Approach 1:
The patent applies local quality by creating receiving sections with reduced material thickness only where mounting brackets need to be accommodated, while maintaining full thickness in other areas for overall structural stability. This localized thinning allows the window frame to lie flush with the roofing plane without compromising the overall dimensional stability of the installation aid.
2Ease of manufacture
If the plate portion has uniform thickness throughout, then manufacturing is simplified, but positioning of mounting brackets becomes difficult without additional guidance features
Solution Approach 1:
The patent uses visual indication features (analogous to color changes) by creating receiving sections with different surface characteristics or visual markers that guide installers to the correct mounting bracket positions. These indications may include color-coded areas, textured surfaces, or visual contrasts that make positioning accurate without requiring complex manufacturing.
3Ease of operation
If the installation aid elevates the window above the roofing plane, then mounting bracket accommodation is facilitated, but additional insulating and weather-proofing materials are required
Solution Approach 1:
The patent extracts the mounting bracket accommodation function from the overall thickness of the installation aid by creating localized receiving sections. This allows mounting brackets to be properly positioned without elevating the entire window frame above the roofing plane, thereby eliminating the need for additional insulating and weather-proofing materials while maintaining ease of bracket installation.

AI summary
An installation aid is adapted for use when mounting a window frame in a roof structure of a building. The installation aid comprises a plate portion adapted for being arranged on an exterior side of the roof structure, so that it extends in parallel with the plane of the roof structure. The plate portion has top, bottom and side members defining an inner edge, said inner edge defining an opening, the shape and size of the opening substantially matching the shape and size of the window frame. The plate portion further comprises at least one receiving section adapted for accommodating a mounting bracket of the window frame. Such an installation aid may form part of a sealing collar. A method of mounting a window frame in a roof structure using an installation aid is also disclosed.
