Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gutter systems often clog due to debris accumulation, which hampers efficient rainwater drainage, as they lack effective mechanisms to manage velocity and rotation of rain and debris.
Innovation Solution
A gutter debris chute with a curved design and vanes that increases the velocity and imparts rotation to rain and debris, preventing clogging in the chute and downspout by directing them into a circular flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional gutter systems are used, then installation is simple, but debris accumulates and causes clogging
Solution Approach 1:
The chute is designed with a curved configuration that directs rain and debris downward in an arc, increasing velocity and preventing debris from settling. The curved geometry transforms linear flow into rotational motion, effectively throwing debris against the chute walls to maintain flow momentum and prevent clogging.
Solution Approach 2:
The system incorporates movable vanes within the chute that rotate with the flowing rain and debris. These vanes dynamically adjust to the flow conditions and impart rotational force to the debris stream, creating a spinning motion that prevents accumulation and maintains continuous flow through the downspout.
2Reliability
If velocity of rain and debris is increased, then clogging in chute is inhibited, but energy loss increases
Solution Approach 1:
The curved chute design naturally accelerates flow through gravitational conversion while the curve length is optimized to provide sufficient velocity increase without excessive energy expenditure. The curvature transforms potential energy to kinetic energy efficiently, achieving the needed velocity boost with minimal additional energy input.
Solution Approach 2:
The rotating vanes capture kinetic energy from the flowing rain and debris, converting some linear motion into rotational motion. This dynamic interaction maintains flow velocity while the rotation prevents clogging, effectively redistributing energy rather than simply increasing it, thereby reducing overall energy loss.
3Reliability
If vanes are added to impart rotation, then downspout clogging is prevented, but device complexity increases
Solution Approach 1:
The vanes are designed to be free-moving components that rotate passively with the flow rather than requiring active control mechanisms. This dynamic design allows the vanes to automatically adjust to varying flow conditions and debris loads, providing effective rotation and clogging prevention without complex control systems or additional actuators.
Solution Approach 2:
The vanes utilize the kinetic energy of the flowing rain and debris themselves to generate the rotational motion needed for clogging prevention. The system is self-powered by the flow it manages, requiring no external energy source or complex control mechanisms, thereby adding functionality without proportionally increasing system complexity.
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 solution effectively inhibits debris clogging in both the chute and downspout, ensuring efficient drainage of rainwater by enhancing the velocity and rotation of debris, thus preventing common clogging issues in gutter systems.
Implementation Method 1
The chute curves downwardly between each of the entries and the exit thereby facilitating the chute to increase the velocity of the rain and debris when the rain and debris moves toward the exit
Implementation Method 2
The chute has a plurality of vanes each is disposed in the chute and each of the vanes is oriented to surround the exit. Each of the vanes is curved thereby urging the rain and debris to flow in a circular direction

AI summary
A gutter debris chute assembly includes a chute that has a pair of entries that is each attachable to a respective pair of gutters on a building to receive rain and debris from the gutters. The chute has an exit that is positioned between the entries. The exit is attachable to a downspout on the building to direct the rain and debris into the downspout. The chute curves downwardly between each of the entries and the exit thereby facilitating the chute to increase the velocity of the rain and debris when the rain and debris moves toward the exit. In this way the chute inhibits the debris from clogging in the chute. The chute has a plurality of vanes each is disposed in the chute and each of the vanes is oriented to surround the exit. Each of the vanes is curved thereby urging the rain and debris to flow in a circular direction to inhibit the debris from clogging in the downspout.
