Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gutter guard systems are ineffective in managing high volumes and flowrates of rainwater, leading to rainwater overflow and debris matting, which can cause damage and increase maintenance costs.
Innovation Solution
The development of a gutter guard system with a novel screen assembly that includes a mesh screen and a grid, featuring a raised section to slow down the flow of rainwater and enhance airflow, thereby preventing debris matting and ensuring efficient water infusion into the gutter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mesh screen is used to cover the rain gutter, then debris is prevented from entering the rain gutter, but the flowrate of rainwater across the screen becomes too fast for satisfactory infiltration
Solution Approach 1:
The screen incorporates raised sections at specific locations to create localized flow resistance. These raised sections are positioned strategically to intercept and slow down water flow in critical areas, allowing water to pool and infiltrate through the screen more effectively, while the rest of the screen maintains its debris-blocking function.
Solution Approach 2:
The screen transitions from a flat two-dimensional structure to a three-dimensional structure with raised sections. This vertical dimension adds flow management capability by creating physical barriers that slow water movement across the screen surface, enabling better water-gutter interaction without compromising debris prevention.
2Reliability
If the flowrate of rainwater across the screen is high, then the screen effectively blocks debris, but rainwater passes over the gutter guard system and pours onto the ground causing damage
Solution Approach 1:
Raised sections are positioned at specific locations on the screen to create localized flow resistance. These sections intercept and slow down water flow in critical areas, allowing water to pool and infiltrate through the screen more effectively, while the rest of the screen maintains its debris-blocking function.
Solution Approach 2:
The raised sections perform preliminary action by intercepting and slowing water flow before it reaches the gutter opening. This preliminary flow management ensures water has adequate time to infiltrate through the screen and enter the gutter, preventing overflow and damage to the structure below.
3Productivity
If splashguards are installed at the roofline to divert and slow the flow of rainwater, then water flow is managed, but debris becomes trapped behind the splashguard requiring periodic cleaning
Solution Approach 1:
The patent extracts the flow management function from a separate splashguard component and integrates it directly into the screen structure through raised sections. This integration eliminates the need for separate splashguards and their associated debris-trapping problems, while maintaining effective water flow management.
Solution Approach 2:
The screen combines multiple functions into a single integrated structure: debris blocking through the mesh, flow management through raised sections, and water infiltration facilitation. This merging of functions eliminates the need for separate splashguards and reduces maintenance requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively manages high volumes of rainwater, reduces debris matting, and minimizes the need for periodic cleaning, thereby protecting the gutter system and reducing maintenance costs.
Implementation Method 1
The raised section provides a barrier to the flow or rainwater that slows the rainwater as it flows across the raised area of the screen
Implementation Method 2
Such a screen covers the rain gutter and stops debris from entering the rain gutter while allowing rainwater to pass through the screen into the rain gutter

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.
