Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sealing methods, such as labyrinth seals and gaskets, are limited in their ability to accommodate varying roof window inclinations, requiring different flashing arrangements for different roof structures, which complicates installation and maintenance.
Innovation Solution
A sealing gasket with a compressible section and an attachment section featuring parallel legs and recesses that allow engagement with flashing members, enabling optimal positioning for different inclination angles and ensuring uninterrupted weatherproofing, even when the angle of the roof window changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional labyrinth seals or fixed-position gaskets are used, then sealing effectiveness is improved, but adaptability to different roof window inclinations deteriorates
Solution Approach 1:
The sealing gasket is designed with a compressible sealing section that can dynamically adjust its position and compression state. The attachment section with multiple legs and recesses allows the gasket to adapt to different inclination angles by changing its mounting configuration, transforming a static sealing solution into a dynamic one that responds to varying installation conditions.
Solution Approach 2:
The invention changes the geometric parameters of the attachment section by providing multiple legs at different positions and orientations with corresponding recesses. This allows the same gasket to be mounted at various angles by selecting different leg-recess combinations, thereby changing the installation parameters to match different roof window inclinations while maintaining sealing effectiveness.
2Adaptability or versatility
If different flashing arrangements are provided for different roof inclinations, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The sealing gasket is designed as a universal component with multi-functional attachment capabilities. The attachment section includes multiple legs and recesses that can be configured in different ways to accommodate various inclination angles, allowing a single gasket design to serve multiple functions across different roof window applications, thereby eliminating the need for multiple specialized flashing arrangements.
Solution Approach 2:
The attachment section is segmented into multiple independent legs with corresponding recesses, each capable of engaging with flashing members at different orientations. This segmentation allows flexible configuration of the same gasket for different inclinations by selecting which legs and recesses to engage, reducing the need for multiple complete flashing arrangements.
3Reliability
If the gap dimensions are constrained for labyrinth seals to work, then sealing performance is improved, but ease of operation deteriorates
Solution Approach 1:
The compressible sealing section acts as an intermediary element between the flashing members. Instead of requiring precise gap dimensions for the labyrinth seal to work, the compressible material accommodates variations in gap size and flashing member positioning while still providing effective sealing, thereby mediating between the sealing requirement and installation flexibility.

Function Achieved in This Case
The sealing gasket provides versatile weatherproofing by allowing the same flashing members and gaskets to be used across a wide range of roof window inclinations, ensuring continuous sealing and adaptability without the need for multiple flashing arrangements.

AI summary
A sealing gasket (4) for use between flashing members (31,32) is disclosed. It comprises a compressible sealing section and an attachment section comprising at least two legs configured for engagement with a flashing member, both sections extending over substantially the entire length of the sealing gasket. The at least two legs of the attachment section project from a base section of the attachment section so that a first recess and a second recess extending in parallel are defined, said first and second recesses being configured for engagement with a flange, ridge, or leg on a flashing member. The invention further relates to a flashing arrangement and to a method of sealing a gap between flashing members for a roof window.
