Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gutter systems face challenges in preventing debris buildup while allowing water to flow effectively, as better debris exclusion often results in water overflow and poorer water infiltration, leading to safety hazards and clogs.
Innovation Solution
A debris shield system with a gutter cap, screen, and roof coupler featuring water adhesion and capture features, such as ridges and apertures, that slow water flow and encourage water entry into the gutter while keeping debris out, along with a modular design for easier installation and adaptation to various systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cover is designed to keep debris out effectively, then debris exclusion is improved, but water infiltration deteriorates causing water to run over the edge
Solution Approach 1:
The gutter cover is segmented into multiple functional zones: a screen portion with apertures for water infiltration, ridges for water adhesion and flow direction, and a body portion for structural support. This segmentation allows each zone to perform its specific function optimally while working together to resolve the contradiction between debris exclusion and water infiltration.
Solution Approach 2:
Different portions of the gutter cover have different properties: the screen portion provides fine debris filtration, the ridges provide water adhesion and flow control, and the body provides structural integrity. This local differentiation of qualities allows the cover to simultaneously exclude debris while maintaining effective water infiltration.
2Productivity
If a cover is designed to allow water to infiltrate easily, then water infiltration is improved, but debris entry increases causing clogs and blockages
Solution Approach 1:
The screen portion of the gutter cover incorporates a porous structure with apertures that are sized to allow water molecules to pass through while blocking larger debris particles. This porous design enables effective water infiltration while maintaining debris exclusion, resolving the contradiction between the two requirements.
3Productivity
If gutter systems are designed to carry and redirect water, then water transport is improved, but debris buildup occurs causing blockages
Solution Approach 1:
The gutter cover with its screen and ridge structure performs preliminary action by filtering debris and directing water flow before water enters the gutter. This preliminary filtration and flow direction prevents debris buildup in the gutter while maintaining effective water transport, addressing the contradiction between the two functions.

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 captures water runoff while preventing debris accumulation, reducing the risk of clogs and safety hazards by ensuring water flows into the gutter while keeping debris out, and allowing for easier installation and customization.
Implementation Method 1
one or more ridges formed integrally with the body and provided on a first side, the one or more ridges extending along the second direction and configured to impede a fluid flow occurring substantially along the first dimension
Implementation Method 2
a plurality of apertures formed through the body and extending between the first side and the second side; wherein the plurality of apertures are configured to permit the fluid flow to pass therethrough
Implementation Method 3
a coupling portion configured to cooperate with an interface of a roof coupler; wherein the roof coupler further comprises a channel formed by the interface and configured to receive the coupling portion and to removably and securely couple the roof coupler to the body
