Pivoting Downspout Extension Using Water-Triggered Bucket Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current downspout extensions require manual movement and reattachment, can be hazardous, and are often aesthetically unpleasing or costly to install, failing to automatically adjust to water flow without obstructing the ground.
Innovation Solution
A pivotable downspout extension system comprising an adapter coupled to a fixed-position downspout, a bucket hingedly attached to the adapter, and an extension arm that pivots based on water weight, automatically adjusting between vertical and lowered positions to release water without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a downspout extension is extended into the yard to release water farther out, then water diversion effectiveness is improved, but it becomes a hazard when children are playing and obstructs the ground
Solution Approach 1:
The downspout extension is designed to be movable rather than fixed, allowing it to dynamically change position between extended and retracted states. The extension can be moved into a lowered position for effective water diversion or raised/removed to eliminate safety hazards and ground obstruction, resolving the contradiction between effectiveness and safety.
2Ease of operation
If a downspout extension is manually moved and detached during yardwork, then ground obstruction is reduced, but it requires continuous manual intervention and time
Solution Approach 1:
The system incorporates an automatic sensor-based mechanism that detects when yardwork equipment (such as a lawnmower) approaches and automatically retracts the downspout extension without manual intervention. This eliminates the time loss associated with manual movement while maintaining ground accessibility during yardwork.
3Device complexity
If a hinge-style downspout extension is manually actuated to fold against the downspout, then device complexity is reduced, but it still requires manual intervention every time it needs to be moved
Solution Approach 1:
While maintaining the simple hinge-style structure for low complexity, the system adds an automatic sensor and actuation mechanism that detects approaching yardwork equipment and automatically triggers the extension to fold against the downspout. This provides the automation needed to eliminate manual intervention while preserving the structural simplicity of the hinge design.
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 positions itself based on water flow, eliminating the need for manual movement and reattachment, enhancing safety and aesthetics while maintaining effective water diversion without obstructing the ground.
Implementation Method 1
The bucket and the extension arm remain in a substantially vertical position until 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
Implementation Method 2
one or more springs on an adapter, coupling a bucket to a fixed-position downspout. Once the water is released, the spring retracts, pulling the bucket and the extension arm back into the substantially vertical position

AI summary
A pivotable downspout extension system includes an adapter coupleable to a fixed-position downspout via a downspout aperture, a bucket hingedly coupleable to the adapter, and an extension arm. The extension arm is received by an extension arm receiving portion located on the bucket. The bucket and the extension arm remain in a substantially vertical position until 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. The bucket with the extension arm then pivots on a fulcrum point, allowing the water to exit the extension arm. Once emptied, the weight chamber of the bucket pivots the bucket and extension arm to the substantially vertical position.
