Roof Window Blind Frame Moisture Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof windows face issues with water penetration, especially in the lower areas, due to external weather conditions, which requires additional sealing efforts during manufacturing and assembly.
Innovation Solution
Incorporating a moisture-conducting means that bridges the upper edge of the lower transverse leg of the roof window frame, allowing water to drain outwards, either as part of the holding device or separately, ensuring water does not penetrate into the interior space, even during extreme weather.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional seal or sealing compound is used to prevent water penetration, then water protection is improved, but manufacturing complexity and assembly effort increase
Solution Approach 1:
The patent extracts the water protection function from the sealing compound and transfers it to the cover plate structure itself. The cover plate is designed with an overlapping configuration where the front cover plate extends beyond the rear cover plate, creating a built-in water diversion mechanism that eliminates the need for additional sealing materials.
Solution Approach 2:
The cover plate structure serves dual functions: it provides structural coverage and simultaneously acts as a water diversion system. The overlapping design of the cover plates creates self-draining channels that guide water away from critical areas without requiring external sealing components.
2Reliability
If additional seal or sealing compound is used to prevent water penetration, then water protection is improved, but assembly effort increases
Solution Approach 1:
The patent removes the sealing compound step from the assembly process by integrating water protection into the cover plate design. The overlapping cover plates create automatic water diversion channels that function without additional sealing materials, simplifying assembly.
Solution Approach 2:
The cover plate assembly automatically provides water protection through its geometric configuration. The front cover plate overlaps the rear cover plate to form built-in drainage channels that self-regulate water flow, eliminating the need for separate sealing operations during assembly.
3Stability of the object's composition
If cover plate is securely fastened to prevent unintentional detachment, then cover plate stability is improved, but water drainage capability may be reduced
Solution Approach 1:
The patent divides the cover plate system into multiple segments (front cover plate and rear cover plate) that are fastened at specific locations. This segmentation allows the cover plates to be securely attached at mounting points while maintaining open drainage channels between the segments, enabling both stability and water drainage.
Solution Approach 2:
The fastening is applied locally at specific mounting points rather than covering the entire surface. This localized fastening approach secures the cover plates where structural support is needed while preserving the water drainage pathways in the overlapping regions between the front and rear cover plates.

AI summary
The residential roof window (1) has a blind frame (3) with a lower transverse leg at an upper edge (15). A window sash (4) is formed with side legs (7), and has a moisture conductive medium. The moisture conductive medium bridges the upper edge of the lower transverse leg. The moisture conductive medium dissipates the moisture due to gravitational influences.
