Corner Gutter Screen With Cantilever Plate For Debris And Water Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rain gutter assemblies fail to effectively prevent debris entry and manage water cascading at inside corner scenarios, leading to inefficiencies in debris collection and water redirection.
Innovation Solution
A screen assembly for inside rain gutter corners featuring a screen with cantilevered central portions and a frame structure that includes a dam and plate for redirecting cascading water, preventing debris entry while allowing water to flow into the gutters and redirecting excess water back into the gutter sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a screen assembly is installed at the inside corner of rain gutters, then debris entry into gutters is prevented, but water cascading off the roof valley cannot be effectively collected and redirected
Solution Approach 1:
The screen assembly is divided into multiple functional segments: a screen portion for debris blocking, a cantilevered central portion for water redirection, and a frame structure with dam and plate components. This segmentation allows each part to perform its specific function independently, solving the contradiction between debris prevention and water collection.
Solution Approach 2:
The screen extends in a cantilevered fashion beyond the outboard edges of the gutter sections, creating a dimensional extension that projects outwardly to intercept cascading water. This dimensional change allows the screen to perform both debris blocking and water redirection functions simultaneously.
2Ease of manufacture
If the screen assembly uses a simple structure, then manufacturing and installation are easier, but it cannot effectively control water cascading at inside corners
Solution Approach 1:
The frame structure merges multiple functions into a single integrated component: it mounts the screen, defines the cantilevered plate, and creates the dam structure. This merging reduces the number of separate parts while maintaining effective water cascading control, balancing simplicity with reliability.
Solution Approach 2:
The dam structure acts as an intermediary element between the screen and the plate, facilitating water redirection. This intermediary component enables the system to control water cascading effectively without requiring complex mechanisms, maintaining ease of manufacture while improving reliability.
3Productivity
If the screen assembly extends beyond the gutter sections to catch cascading water, then water redirection is improved, but the structure becomes more complex
Solution Approach 1:
The frame structure serves multiple functions: mounting the screen, defining the cantilevered plate geometry, creating the dam, and providing structural support. This multi-functionality reduces the need for additional separate components, thereby improving water redirection capability without proportionally increasing structural complexity.

AI summary
A rain gutter screen assembly for use at the inside corner of a rain gutter. The assembly includes a screen having portions sized to overlie intersecting ends of the rain gutter sections, to allow water cascading down the roof corner to flow into the intersecting ends while blocking the entry of debris into the intersecting ends, and a central portion sized to extend outwardly beyond outboard edges of the intersecting ends in cantilever fashion; and a frame structure mounting outboard edges of the screen and defining a plate extending outwardly beyond the outboard edges of the intersecting ends in cantilever fashion in underlying relation to the central screen portion, whereby cascading water trajecting beyond the intersecting ends may pass through the central screen portion and onto the cantilever plate for redirection into the rain gutter sections.
