Flexible Gutter Shield with Convex Foraminous Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gutter guard systems require attachment members for securing and often fail to ensure complete water flow into the eavestrough due to insufficient surface tension when water volume increases.
Innovation Solution
A flexible gutter guard with a foraminous central portion and side structures that can bend for secure placement without attachment members, featuring a convex configuration and flange arrangement to prevent foreign matter and facilitate water drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid gutter guard with attachment members is used, then the guard provides stable protection against foreign matter, but the installation complexity and requirement for attachment members increases
Solution Approach 1:
The gutter guard employs a flexible membrane structure that can be bent and shaped to fit over the gutter opening. This flexible shell provides stable protection through its ability to conform to the gutter geometry and maintain position without rigid attachment members, resolving the contradiction between protection stability and installation complexity
Solution Approach 2:
The flexible membrane allows the gutter guard to dynamically adapt to the gutter shape during installation and to flex with environmental conditions. This dynamic property enables the guard to maintain reliable protection without requiring fixed attachment members, reducing device complexity while preserving stability
2Ease of operation
If the gutter guard is made flexible to eliminate attachment members, then the installation simplicity improves, but the structural stability may be compromised
Solution Approach 1:
The flexible membrane is formed with a predetermined convex curvature that matches the concave shape of the gutter opening. This curvature relationship allows the membrane to nestle into the gutter, providing structural stability through geometric interlocking while maintaining installation simplicity through the flexible material
3Productivity
If the central portion is made convex to facilitate water flow, then the water drainage efficiency improves, but the manufacturing complexity increases
Solution Approach 1:
The convex curvature of the central portion is achieved by controlling the forming parameters during manufacturing, such as the degree of bending and the radius of curvature. By optimizing these parameters, the patent achieves effective water flow facilitation while keeping the manufacturing process feasible for flexible materials, balancing drainage efficiency with manufacturing ease
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 flexible gutter guard effectively prevents foreign matter from entering the eavestrough while ensuring complete water flow into the gutter, eliminating the need for attachment members and enhancing maintenance accessibility.
Implementation Method 1
the foraminous central portion being formed of a flexible material to permit the central portion to bend to thereby permit placement of the gutter cover in position
Implementation Method 2
the cover have an outer edge which flows downwardly and the water flow follows the curved portion due to surface tension and thereafter cascades into the eavestrough
