Rain Gutter Dredger Using Water Flow for Automatic De-clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rain gutter and downspout cleaning systems are ineffective and require manual operation, often leading to clogging and water accumulation, which can cause damage to buildings.
Innovation Solution
An automatic de-clogging system that uses uni-directional or oscillating motions of a cleaning member driven by liquid flow through the downspout, powered by gravity or a cranking device, to remove debris from rain gutters and downspouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning systems are used for rain gutters and downspouts, then the cleaning operation can be performed, but the system requires frequent manual intervention and labor
Solution Approach 1:
The patent implements a self-cleaning system where rainwater flow automatically activates a motion device that propels a cleaning member through the downspout to remove debris. The system serves itself by using the natural water flow to power the cleaning mechanism, eliminating the need for manual intervention and transforming the gutter system from requiring periodic manual cleaning to automatic self-maintenance during rainfall events
Solution Approach 2:
The patent employs dynamic motion mechanisms including oscillating motion and uni-directional motion of the cleaning member within the downspout. The motion device converts the linear flow of rainwater into mechanical motion that moves the cleaning member dynamically through the downspout, enabling effective debris removal without manual operation
2Reliability
If stationary nets or covers are installed to prevent debris entry, then debris prevention is improved, but the products get clogged after a short period due to their stationary nature
Solution Approach 1:
The patent replaces stationary protective elements with a dynamic cleaning member that actively moves through the downspout. The cleaning member oscillates and moves unidirectionally to continuously clear debris, transforming the system from passive stationary protection that clogs to active dynamic cleaning that maintains flow capability over extended periods
Solution Approach 2:
The motion device ensures continuous cleaning action during rainfall by constantly propelling the cleaning member through the downspout. This continuous mechanical action prevents debris accumulation and maintains clear flow paths throughout the operational period, unlike stationary nets that accumulate debris over time
3Productivity
If current cleaning systems are used, then debris removal is achieved, but the systems are ineffective and require professional services due to high location
Solution Approach 1:
The system eliminates the need for professional services by implementing self-powered cleaning. The motion device uses rainwater flow to automatically propel the cleaning member through the downspout, making the high-location gutter system self-maintaining without requiring manual access or professional intervention
Solution Approach 2:
The patent utilizes hydraulic principles by channeling rainwater flow through the motion device to generate mechanical motion. The water flow itself becomes the power source that drives the cleaning mechanism, leveraging the existing water pressure and flow to achieve effective debris removal from hard-to-reach locations
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 system effectively maintains the flow of water through gutters and downspouts by automatically removing debris, reducing the need for frequent manual cleaning and preventing damage from clogging.
Implementation Method 1
motions of the liquid flowing through the downspout and through said motion device caused by gravity
Data Source
AI summary
This disclosure is directed to a system designed for automatic de-clogging a rain gutter and a downspout. The system (also referred to as a gutter dredger) comprises a motion device (motor) and a cleaning device. When it is raining, rain water can power the system to cause reciprocating motions of the cleaning device that can result in de-clogging of a gutter and a downspout that have the system installed. A debris removal device may be positioned in the downspout to remove big debris before it moves into the motor. The gutter dredger can be used for automatically de-clogging a gutter and downspout whenever it is raining.
