Gutter Protection Device with Porous Foam and Hook Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gutter protection devices allow debris to accumulate on their surface, preventing rainwater from flowing into the gutter and leading to accumulation near the foundation of buildings.
Innovation Solution
A gutter protection device with a front portion, central portion, and rear portion, featuring perforated sections and a water draining chamber design that directs rainwater into the gutter while preventing debris accumulation, and includes a foam insert to enhance drainage and support the gutter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional leaf guard is installed over the gutter, then debris is blocked from entering the gutter, but rainwater cannot flow through the leaf guard into the gutter
Solution Approach 1:
The patent employs a porous foam material that allows rainwater to pass through while blocking debris. The foam's cellular structure provides sufficient porosity for water permeability while maintaining surface integrity to prevent leaf and debris accumulation, resolving the contradiction between debris blocking and rainwater flow
Solution Approach 2:
The invention combines foam material with a mesh or screen layer to create a composite structure. The foam provides bulk filtering and water absorption capabilities, while the mesh layer enhances debris blocking. This composite approach maintains water flow pathways while effectively preventing debris entry
2Object-affected harmful factors
If a solid leaf guard surface is used to prevent debris entry, then debris is blocked, but the surface area available for rainwater flow is reduced
Solution Approach 1:
The foam material's inherent porosity provides numerous microscopic flow pathways for rainwater while presenting a continuous surface to debris. This eliminates the need for large macroscopic openings that would allow debris entry, maintaining effective water flow area without compromising debris blocking
3Productivity
If a foam insert is added to the gutter protection device, then drainage is enhanced and gutter support is provided, but device complexity increases
Solution Approach 1:
The foam insert serves multiple functions simultaneously: it acts as a drainage enhancement element by wicking water toward the gutter, provides structural support to hold the gutter in position, and contributes to debris blocking. This multi-functionality justifies the added complexity by delivering multiple benefits from a single component

AI summary
A gutter protection assembly includes a gutter and a gutter protection. The gutter includes a front wall, a bottom wall and a rear wall, the rear wall having a crimp protruding outwardly from an outer face of the rear wall of the gutter. The gutter protection device includes a front portion engageable with the front wall of the gutter, and a rear portion. The rear portion includes a gutter wall-engaging section having an outer downward segment provided with a hook. The hook is configured to engage with the crimp to provide a support for the gutter to hang from. The gutter assembly is securable to a supporting structure through an outwardly extending section projecting upwardly from the gutter wall-engaging section and extending above the rear wall of the gutter when in the gutter protection assembly, with the gutter hanging from the gutter protection device.
