Gutter Guard Screen Grid for Rainwater Infiltration and Debris Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gutter guard systems are inefficient in managing high volumes and flowrates of rainwater, leading to rainwater overflow and debris matting, which can cause damage and maintenance issues.
Innovation Solution
A novel gutter guard system with a screen assembly featuring a raised section and grid structure that slows the flowrate of rainwater, enhancing water infusion into the gutter while preventing debris matting, and potentially eliminating the need for splashguards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mesh screen is used to cover the rain gutter, then debris is stopped from entering the rain gutter, but the flowrate of rainwater across the screen is too fast for satisfactory infiltration into the rain gutter
Solution Approach 1:
The screen is divided into multiple rows of apertures arranged in a grid pattern, with each row offset from the previous row. This segmentation allows water to be distributed across multiple smaller opening paths rather than flowing across a single large opening, reducing the flowrate speed while maintaining effective debris blocking.
Solution Approach 2:
The screen features varying aperture sizes and densities in different regions. The grid pattern creates localized zones with different water flow characteristics, allowing optimized water infiltration in specific areas while maintaining overall debris protection across the entire screen surface.
2Area of stationary object
If the flowrate of rainwater across the screen is high, then the screen covers more area, but rainwater passes over the gutter guard system without flowing downward into the rain gutter
Solution Approach 1:
The screen's grid pattern segments the water flow into multiple smaller streams as it passes across the aperture rows. This segmentation reduces the velocity and volume of water moving across any single point, enabling better gravitational flow downward into the gutter while maintaining extensive area coverage.
Solution Approach 2:
The offset grid pattern creates a three-dimensional water flow path where water must navigate between rows of apertures at different positions. This dimensional arrangement extends the water's path length and reduces its horizontal flowrate, improving vertical channeling into the gutter while preserving broad area coverage.
3Productivity
If splashguards are installed at the roofline to divert and slow the flow of rainwater, then rainwater flow is managed, but debris becomes trapped behind the splashguard requiring periodic cleaning
Solution Approach 1:
The water flow management function is extracted from a separate splashguard component and integrated directly into the gutter guard screen structure. The grid pattern of the screen itself performs the flow slowing and diversion function, eliminating the need for separate splashguards and the associated debris trapping and cleaning maintenance.
Solution Approach 2:
The water flow management function is merged with the debris blocking function in a single integrated screen structure. The grid pattern simultaneously achieves both purposes, eliminating the need for separate components and reducing maintenance requirements by preventing debris accumulation.
4Reliability
If prior art gutter guard systems are used, then debris protection is provided, but rainwater flow is not effectively managed resulting in overflow and debris matting
Solution Approach 1:
The screen's grid pattern segments water flow into multiple smaller streams that move more slowly and infiltrate better into the gutter. This segmentation prevents overflow by distributing water across many small paths rather than allowing concentrated flow, while maintaining effective debris blocking.
Solution Approach 2:
The screen design changes the flowrate parameter by creating a grid pattern that reduces water velocity and increases infiltration time. This parameter modification allows high-volume rainwater to be handled effectively, preventing overflow and debris matting while maintaining protective function.

AI summary
Disclosed herein are gutter guard systems arranged to efficiently manage the flow of rainwater across the system and prevent the matting of debris onto the system. In one exemplary embodiment, a gutter guard system includes a main body and a screen covering the main body. The gutter guard assembly further includes a front receiver and a rear receiver that secure the screen to the main body. The screen includes at least one feature arranged to manage the flowrate of rainwater across the gutter guard system. In one example, the feature is a raised rounded area that slows the flowrate of rainwater across the gutter guard system. In another embodiment, the screen includes an upwardly angled section and a transition section. Once assembled and installed, the transition section and optionally the angled section forms hurdles that slows the flowrate of rainwater across the gutter guard system.
