Spring Steel Clip for Gutter Guard Attachment

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing gutter guards often require time-consuming attachment methods like screws or rivets, which penetrate the guard and gutter, and fail to maintain integrity against heavy debris and settled debris over time, allowing smaller particles to pass through.

Innovation Solution

A flexible and resilient clip made of spring stainless steel with upwardly curved tabs and elongated second tabs that removably secures the front lip of the gutter guard to the gutter without connectors, using a rotation and bending mechanism to engage the gutter's curved end and holes in the guard panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws or rivets are used to attach the gutter guard to the gutter, then the attachment is secure, but the installation is time-consuming and requires penetration of the guard and gutter

Engineering Contradiction:

Improveattachment securityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the traditional mechanical fastening system (screws or rivets requiring penetration and tools) with a simple clip mechanism that uses elastic deformation and friction. The clip is inserted through openings in the gutter guard and engaged with the gutter lip, providing secure attachment without penetration or complex tools, thus dramatically reducing installation time while maintaining reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Area of stationary object

If a flat guard structure is used, then the guard covers the gutter opening, but the integrity cannot be maintained against heavy debris or settled debris

Engineering Contradiction:

Improvecoverage areaVSAvoidstructural integrity

Core Design Contradiction:

Area of stationary objectVSStrength

Solution Approach 1:

The patent introduces curvature to the previously flat guard structure by providing a curved lip portion on the gutter that receives the clip. The clip itself has a curved configuration that matches this lip, creating a rounded engagement point. This curvature distributes forces more effectively and prevents the guard from flexing or deforming under the weight of heavy or settled debris, maintaining structural integrity while preserving full coverage area.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Strength

If the guard structure is made rigid to maintain integrity, then debris resistance is improved, but water flow may be obstructed and installation becomes difficult

Engineering Contradiction:

Improvedebris resistanceVSAvoidinstallation ease

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the clip itself flexible rather than rigid. The clip is formed from a flexible material that can be easily inserted through the openings in the gutter guard and then engaged with the gutter lip. Once installed, the clip's flexibility allows it to conform to slight variations in the gutter and guard alignment, facilitating easy installation and removal while maintaining sufficient rigidity to resist debris forces.

Inventive Principle:

Principle #15Dynamics

4Reliability

If connectors like screws or rivets are used, then the guard is securely attached, but penetration of the guard and gutter occurs causing potential damage

Engineering Contradiction:

Improveattachment securityVSAvoidpenetration damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces the clip as an intermediary component between the gutter guard and the gutter. Instead of directly penetrating both the guard and gutter with screws or rivets, the clip serves as a mediating element that attaches to the gutter guard through friction and engagement with the curved lip, distributing attachment forces without causing penetration damage to either the guard or gutter. This intermediary approach eliminates the harmful penetration effect while maintaining secure attachment.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A clip for removably securing the front lip of a gutter guard having holes therethrough to the underlying front lip of a gutter having a downwardly and forwardly extending end portion. The clip comprises an elongated body with a forwardly and upwardly extending first tab at a front end thereof and a rearwardly extending second tab at a rear end thereof. The first tab can be inserted through a first hole at the front of the gutter guard with the body in an upwardly extending first position so that the first tab is located adjacent to and beneath the end portion of the gutter. The body can then be rotated downwardly toward the gutter guard to a second position wherein the first tab is moved upwardly to engage the end portion of the gutter and the second tab is received within a second hole in the gutter guard.
