Solution Overview

Problem

Existing systems fail to provide a single, effective solution for removing ice, snow, leaves, and debris from gutters and roofs without using heat, while also preventing ice and snow from sliding off and causing damage or injury.

Innovation Solution

A self-cleaning gutter system comprising an L-shaped gutter frame, an inflatable membrane, and a flexible gutter cover that lifts debris off the roof when inflated, using a blower to manage snow and ice accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heat-tape or heat panels are used to melt ice dams, then ice and snow can be removed from the roof, but the system requires thermal energy input and cannot handle leaves and debris

Engineering Contradiction:

Improveice and snow removal effectivenessVSAvoidthermal energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system divides the roof surface into multiple zones using separate membrane sections, each equipped with its own blower. This segmentation allows targeted snow and ice removal from specific areas without requiring heat application to the entire roof, reducing overall energy consumption while maintaining effective ice and snow removal capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces thermal energy-based ice melting with pneumatic pressure systems. Blowers generate air pressure that is directed through channels under the membrane to lift and remove snow and ice mechanically, eliminating the need for heat-tape or heat panels and their associated thermal energy consumption.

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Productivity

If the membrane is made movable to shake and discharge snow and debris, then cleaning effectiveness is improved, but the structural complexity and control mechanisms increase

Engineering Contradiction:

Improvesnow and debris discharge efficiencyVSAvoidmembrane movement and control system

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The blowers are operated in periodic cycles rather than continuously, creating repeated lifting and shaking motions of the membrane. This periodic action effectively discharges snow and debris through rhythmic movement while minimizing energy consumption and simplifying the control system compared to continuous operation or complex mechanical actuation systems.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The membrane's movement is achieved through pneumatic pressure from blowers rather than complex mechanical actuators, motors, or linkages. The system uses the pressure differential created by the blowers to automatically lift and position the membrane, eliminating the need for additional mechanical complexity while maintaining effective snow and debris discharge.

Inventive Principle:

Principle #25Self-service

3Reliability

If the gutter frame is positioned to retain snow and ice on the roof, then safety and prevention of damage are improved, but the ability to remove gutter contents efficiently is reduced

Engineering Contradiction:

Improveprevention of snow and ice damageVSAvoidgutter contents removal rate

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The membrane is designed to be dynamically movable between a lowered position (for snow/ice retention and safety) and a raised position (for gutter cleaning). This dynamic positioning allows the system to switch between safety mode and cleaning mode, resolving the contradiction between retaining snow/ice on the roof and efficiently removing gutter contents.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The L-shaped gutter frame is pre-positioned to create a containment structure that holds snow and ice on the roof during normal conditions. This preliminary structural arrangement provides inherent safety and damage prevention, while the membrane can be temporarily raised to allow controlled removal of gutter contents when needed.

Inventive Principle:

Principle #10Preliminary action

AI summary

The concept includes improvements in the method and apparatus for removing ice, snow, leaves and other debris from roofs and gutters using a flexible cover attached over the roof that moves via the operation of one or more inflatable membranes positioned under the gutter cover. The concept also uses a gutter frame secured on the surface of a roof which acts as a brake to keep snow and ice from suddenly and unexpectedly sliding off the roof which provides a high level of safety.
