Solution Overview

Problem

Conventional gutter systems face challenges in preventing debris from entering the gutter trough while securely attaching to a supporting surface, as existing solutions often fail to effectively block leaves and other materials while ensuring proper fastening.

Innovation Solution

A gutter cover design featuring a perforated central portion with deflectable fastener-receiving flaps and a fastener abutment that engages with the gutter's rear wall at an oblique angle, allowing for secure attachment to a supporting surface while allowing water to pass through and preventing debris accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a gutter cover is designed to prevent debris from entering the gutter trough, then debris blocking is improved, but the attachment security to supporting surface deteriorates

Engineering Contradiction:
Improvedebris blockingVSAvoidattachment security
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The gutter cover is divided into distinct functional segments: a debris-blocking central portion with deflectable flaps, and attachment portions at the front and rear. The deflectable flaps are segmented to pivot independently, allowing debris to be blocked while fasteners can be inserted through the flaps to secure the gutter to the supporting surface, simultaneously achieving both debris prevention and secure attachment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The gutter cover design integrates multiple functions into a single component: the central portion blocks debris while the perforated sections and deflectable flaps simultaneously provide pathways for fasteners to attach the gutter to the supporting surface. This multi-functional design resolves the contradiction by making the cover both a debris barrier and an attachment mechanism.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If a perforated central portion with deflectable flaps is used, then debris prevention is improved, but the structural complexity increases

Engineering Contradiction:
Improvedebris preventionVSAvoidstructural complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The deflectable flaps are designed to pivot from a first position (blocking debris) to a second position (allowing fastener insertion). This dynamic element allows the same structure to serve multiple functions at different times during installation and operation, reducing the need for additional components and simplifying the overall structure while maintaining effective debris prevention.

Inventive Principle:
Principle #15Dynamics

3Reliability

If fastener abutment is positioned at an oblique angle, then attachment reliability is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveattachment reliabilityVSAvoidangular precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The fastener abutment is pre-positioned at an oblique angle relative to the rear wall during manufacturing, establishing the correct attachment geometry before installation. This preliminary positioning ensures that when fasteners are inserted, they naturally follow the oblique path for optimal attachment reliability, while the angle is built into the mold or forming process rather than requiring complex post-manufacturing adjustments.

Inventive Principle:
Principle #10Preliminary action

AI summary

A gutter cover, the central portion of which comprises a plurality of spaced-apart deflectable fastener-receiving flaps hingedly connected at a junction with the rear portion, the deflectable fastener receiving flaps being pivoted into the trough, below the adjacent section of the central portion, upon insertion of a mechanical fastener therein and into the rear wall of the gutter to secure the gutter to the supporting surface. The rear portion of the cover may also comprise a fastener-abutment extending in the trough, below the central portion, and defining an oblique angle with the rear wall of the gutter, when the gutter cover is engaged with the gutter. The fastener abutment and the rear wall of the gutter are configured to receive a mechanical fastener therein to secure the gutter to a wall, the fastener abutment maintains the mechanical fastener in an oblique angle with the rear wall of the gutter.
