Telescopic Gutter Profile with Reduced End Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic drainage gutter systems are inadequate for multiple roof window installations, as they require multiple gutters to be mounted separately, leading to complex installations and increased risk of errors, and existing solutions with identical profiles are costly and difficult to assemble correctly.
Innovation Solution
A gutter profile with a reduced height at one end section allows for versatile use as either an internal or external profile, enabling connection to another gutter profile with the same cross-section, providing a downwards overlap for efficient water flow and easy assembly, while maintaining compatibility with existing production lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple telescopic drainage gutters are mounted separately for multiple roof window installations, then each gutter can be installed independently, but the installation process becomes complex and the risk of installation errors increases
Solution Approach 1:
The patent combines multiple separate drainage gutters into a single integrated unit. The internal gutter profile is designed to accommodate multiple external gutter profiles simultaneously, allowing multiple roof window drainages to be merged into one continuous drainage system. This eliminates the need for separate mounting of multiple gutters and reduces installation complexity.
Solution Approach 2:
The internal gutter profile is designed with a universal structure that can accommodate multiple external gutter profiles of the same type. The reduced height at one end section allows it to function both as an internal profile for telescopic insertion and as a connection point for additional gutter profiles, providing multi-functionality and simplifying the installation process for multiple roof windows.
2Ease of operation
If identical gutter profiles are used for connection, then assembly becomes easier, but the cost increases and the risk of incorrect assembly increases
Solution Approach 1:
The patent applies local quality by providing a reduced height section only at one end of the internal gutter profile, while the rest of the profile maintains its standard dimensions. This localized modification allows for easier assembly with identical profiles without requiring complete redesign of the entire gutter system, thereby controlling manufacturing costs while improving assembly ease.
3Ease of operation
If external gutter profile is positioned upstream of internal gutter profile, then assembly is simpler, but water can flow in between the gutter profiles
Solution Approach 1:
The patent applies preliminary anti-action by designing the internal gutter profile with a reduced height section that prevents the harmful effect of water infiltration before it can occur. The reduced height creates a downward-facing surface that directs water flow away from the gap between profiles, preemptively preventing water from entering the roof structure even if the assembly orientation is incorrect.

AI summary
The present invention relates to an elongate gutter profile for a telescopic drainage gutter for guiding water away from an aperture in an underroof, which allows for water-tight connection to a further gutter profile with similar geometry of further telescopic drainage gutter. Said gutter profile comprising a first leg and a second leg extending in a longitudinal direction and spaced apart in a transverse direction providing an interior space of the gutter profile, wherein the second leg of the gutter profile comprises an inwardly projecting portion extending into interior space from a top of the second leg, wherein the second leg of the gutter profile comprises a first end section at a first longitudinal end of the gutter profile and a main section next to the first end section, and the height of the first end section is less than the height of the adjoining main section of the second leg. The inventions also relates to telescopic drainage gutters and systems comprising such a gutter profile and to methods for assemblying such systems and method for producing such gutter profiles.
