Irregular-Groove Gutter Guard for Strength Without Blocking Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gutter guards often require additional support structures like frames or corrugations, which reduce the permeable surface area and can collapse under debris load, leading to inefficiencies and maintenance issues.
Innovation Solution
A self-supporting gutter guard design utilizing irregular grooves in a micromesh material that allows for greater permeability and flexibility without the need for additional support structures, enhancing load-bearing capacity and debris prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional gutter guards use additional support structures like frames or corrugations, then structural strength is improved, but permeable surface area is reduced
Solution Approach 1:
The gutter guard is divided into multiple discrete micromesh panels rather than using a continuous solid structure with frames. Each panel is independently supported by the gutter itself, eliminating the need for interconnecting frames while maintaining overall structural integrity through the segmented arrangement
Solution Approach 2:
The patent uses thin micromesh material that is flexible yet strong enough to span across the gutter opening without requiring rigid frame support. The micromesh acts as a flexible barrier that maintains its shape and filtering function while allowing water passage, replacing the need for stiff corrugated structures
2Strength
If conventional gutter guards use frames or corrugations for support, then load-bearing capacity is improved, but device complexity is increased
Solution Approach 1:
The patent extracts and removes the frame and corrugation support structures from the gutter guard design. Instead of adding these complex elements, the invention relies solely on the micromesh material properties and the gutter's inherent structure to provide support, significantly simplifying the overall device
Solution Approach 2:
The gutter itself serves a dual function: it both collects water and provides structural support for the micromesh panels. This eliminates the need for separate support structures, as the gutter's primary structure is utilized to bear the load of debris and support the filtering mesh
3Object-affected harmful factors
If conventional gutter guards use solid structures, then debris prevention is improved, but water flow is reduced
Solution Approach 1:
The patent employs micromesh material with controlled porosity that allows water molecules to pass through while blocking larger debris particles. The mesh structure provides adequate openings for water flow maintenance while maintaining effective debris filtration through the interconnected wire structure

AI summary
A self-supporting gutter guard device is described having a bridge member composed of a decking material having a plurality of orifices, and having a roof side and an opposing gutter lip side, at least one groove disposed in the decking material altering a profile of the deck material to outline a 3-dimensional geometry that spans the bridge member from a proximal end of the bridge member's roof side to a proximal end of the bridge member's gutter lip side, a roof attachment member configured to attach to the roof side of the bridge member, and a gutter attachment member configured to attach to the gutter lip side of the bridge member, wherein the 3-dimensional geometry of the at least one groove enables the device to be self-supporting.
