Solution Overview

Problem

Existing downspout extensions require manual movement and reattachment, can be hazardous, and are often aesthetically unpleasing, while also being costly and time-consuming to install, especially when concealed underground.

Innovation Solution

A pivotable downspout extension system that includes an adapter coupled to a fixed-position downspout, a bucket hingedly coupled to the adapter, and an extension arm that pivots to release water when the bucket fills with sufficient water, automatically returning to a vertical position when empty.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If a downspout extension is extended into the yard, then water can be released farther from the building, but it becomes a hazard when children are playing and obstructs the ground

Engineering Contradiction:
Improvewater release distanceVSAvoidsafety hazard
Core Design Contradiction:
Length of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The downspout extension is designed to be dynamically movable between an extended position for water release and a retracted position for safety. The system uses a pivot mechanism with a fulcrum point, allowing the extension to automatically transition between positions based on water flow conditions, thus resolving the contradiction between extending water release distance and eliminating safety hazards

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a downspout extension is manually moved and reattached during yardwork, then it can be positioned as needed, but it requires constant manual intervention and time

Engineering Contradiction:
Improveposition adjustabilityVSAvoidmanual movement time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The downspout extension system performs self-service by automatically positioning itself based on water flow. When water flows into the bucket, the weight causes the extension to pivot into the extended position automatically. When the bucket empties, the spring mechanism automatically returns the extension to its stored position, eliminating the need for manual intervention and time consumption

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a hinge-style downspout extension is used, then it can be manually folded against the downspout, but it still requires manual actuation every time it needs to be moved

Engineering Contradiction:
Improvemanual folding capabilityVSAvoidautomatic movement
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

The system uses a counterweight mechanism where the weight of water in the bucket acts as the activating force. When sufficient water accumulates, its weight overcomes the spring force and pivots the extension into position. When water is released, the spring counterweight automatically returns the extension to its stored position, providing automatic movement without manual actuation

Inventive Principle:
Principle #8Anti-weight (Counterweight)

4Shape

If concealed downspout extensions are installed underground, then aesthetics are improved, but installation becomes costly and time-consuming

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidinstallation cost and time
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The patent describes both above-ground and underground installation configurations. The dynamic pivot mechanism allows the extension to function effectively in either configuration. For underground installation, the system can be concealed while maintaining automatic operation, providing aesthetic improvement without requiring complex trenching and gravel installation, thus reducing installation cost and time

Inventive Principle:
Principle #15Dynamics

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 automatically adjusts its position based on water flow, eliminating the need for manual movement and reattachment, enhancing safety and aesthetics, while reducing installation costs and time.

Implementation Method 1

a sufficient amount of water enters the bucket so as to overcome the weight of a weight chamber of the bucket and move the bucket's center of gravity

Methodology Applied
Scientific EffectCenter of gravity:

Implementation Method 2

the weight of the water in the bucket overcomes the force applied by the springs

Methodology Applied
Scientific EffectGravitation: Gravitation

Implementation Method 3

Once the water is released, the spring retracts, pulling the bucket and the extension arm back into the substantially vertical position

Methodology Applied
Scientific EffectElasticity: Elasticity

AI summary

A pivotable downspout extension system includes an adapter coupleable to a fixed-position downspout, an extension arm pivotally coupled to the adapter, the extension arm having a housing having counterweight apertures, counterweights configured to be received within the counterweight apertures, and a water channel extending from the housing, the water channel forming a pocket where the water channel joins the housing. The water channel remains substantially vertical until water weight exceeds the weight of the counterweights and causes the water channel to pivot and release water.
