Rain Gutter System With Internal Hangers And High-Back Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rain gutter systems often damage the sealing integrity of roofs during installation, fail to address backflow affecting the underlying fascia, and have debris covers oriented at undesirable slopes, leading to inadequate water collection and debris accumulation.
Innovation Solution
A rain gutter system with a continuous cross-sectional profile, integrated drip edge for water direction, high-back for backflow protection, and internal hangers for secure attachment to rafter tails, which supports a debris cover at a predetermined slope, ensuring effective water collection and debris prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional gutter systems are installed using traditional methods, then installation is straightforward, but the sealing integrity of the roof is damaged
Solution Approach 1:
The patent introduces an intermediary component (the specialized hanger system with integrated sealing elements) that mediates between the gutter and the roof structure. This intermediary ensures proper sealing without requiring damage to the roof, resolving the contradiction between easy installation and maintaining roof integrity.
2Productivity
If conventional gutter systems are used, then basic water collection is achieved, but backflow affects the underlying fascia
Solution Approach 1:
The patent applies preliminary anti-action by designing the gutter with a backwall and specialized overflow configuration that prevents backflow before it can damage the fascia. The system proactively counteracts the harmful backflow effect rather than merely responding to it after occurrence.
3Ease of manufacture
If debris covers are installed at conventional slopes, then installation is simple, but debris accumulates and water collection is inadequate
Solution Approach 1:
The patent changes the slope parameter of the debris cover to an optimized angle that simultaneously improves water collection efficiency and prevents debris accumulation. This parameter optimization resolves the contradiction between simple installation and effective water collection.
4Ease of manufacture
If conventional gutter profiles are used, then manufacturing is simple, but water direction and backflow protection are inadequate
Solution Approach 1:
The patent merges multiple functions (water collection, water direction via integrated drip edge, and backflow protection via backwall) into a single continuous cross-sectional profile. This integration maintains manufacturing simplicity while significantly improving water direction control and backflow protection.

AI summary
A rain gutter system including a gutter and at least one internal hanger, wherein the gutter includes a front wall and a back wall interconnected through a bottom and spaced-apart to cooperatively define a water-collecting channel therebetween, the front wall including a lip extending in the direction toward the back wall and a drip edge extending in a direction away from the back wall, the back wall extending upward vertically beyond the height of the front wall, and wherein the at least one hanger is positioned in the channel spaced-apart from the bottom and includes a forward flange extending upwardly from a base for being captured beneath the lip and a rear flange extending upwardly from the base and defining a support surface sloped in a direction toward the drip edge.
