Downspout Adaptor with Membrane Capture for Rainwater Diversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rainwater collection systems for gardening lack versatility in accommodating different downspout sizes and do not efficiently capture and distribute rainwater to soil for irrigation, requiring frequent user intervention and maintenance.
Innovation Solution
A system comprising an adaptor with interchangeable sections to fit both standard downspout sizes, a membrane to capture rainwater from the downspout sides, and a collector conduit to direct rainwater to a rain barrel or soaker hose, with a central passageway for excess water to flow into the downstream downspout, allowing for efficient distribution to soil via a sensor-activated valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a collection system is designed to accommodate both standard downspout sizes, then versatility is improved, but device complexity increases
Solution Approach 1:
The adaptor is divided into two distinct sections: a first section with a first peripheral dimension for receiving a first standard-size downspout, and a second section with a second peripheral dimension for receiving a second standard-size downspout. This segmentation allows each section to be optimized for a specific downspout size while maintaining overall system versatility.
Solution Approach 2:
The adaptor is designed to perform multiple functions: it can receive either first or second standard-size downspouts, capture rainwater through membrane means, transfer rainwater via collector means, and provide overflow pathways. This multi-functionality eliminates the need for separate adaptors for different downspout sizes.
2Productivity
If membrane means are added to capture rainwater from downspout sides, then water capture efficiency is improved, but device complexity increases
Solution Approach 1:
The membrane means are integrated into the adaptor structure itself, merging the rainwater capture function with the existing adaptor body. The membrane means are positioned between the first and second sections, interconnecting them while simultaneously capturing rainwater that would otherwise be lost.
Solution Approach 2:
The membrane means extend outward from the downspout surface into the surrounding space, creating an additional capture surface area in a dimensional sense. This allows the system to capture rainwater from the downspout sides without increasing the linear dimensions of the adaptor significantly.
3Productivity
If collector means are integrated into the adaptor, then rainwater transfer efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The collector means are positioned within the adaptor structure, with the conduit integrated into the adaptor body. The conduit can be attached to either the first or second hole in the sidewalls, nesting the water transfer function within the existing adaptor framework.
Solution Approach 2:
The collector means include holes positioned at specific locations in the sidewalls of the first and second sections, with a conduit that can be selectively attached. This localized positioning optimizes rainwater collection from specific areas while maintaining manufacturing simplicity.
4Reliability
If a central passageway is formed for excess water flow, then system reliability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The central passageway is formed as a distinct feature within the membrane means, separating the overflow function from the rainwater capture function. This extracted passageway provides a dedicated pathway for excess water to flow into the downstream downspout section, preventing backflow and ensuring system reliability.

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 provides a versatile, low-maintenance rainwater collection and distribution solution that efficiently captures and delivers rainwater to soil, reducing user intervention and ensuring consistent irrigation, with potential for expanded use in household water supply if filtered.
Implementation Method 1
membrane means positioned between the first section and the second section interconnecting the first and second sections, the membrane means further capturing and diverting rainwater clinging to sides portions of the downspout
Implementation Method 2
membrane means further capturing and diverting rainwater clinging to sides portions of the downspout
Implementation Method 3
a central passageway formed in the membrane means permitting rainwater exceeding the capacity of the collector means to flow into a downstream section of downspout

AI summary
An adaptor accommodates both of the most predominant sizes of downspouts and, when positioned between an upper and lower section, diverts rainwater through an opening in a sidewall to a collection system such as one or more rain barrels. Preferably, the collection system is attached to a soaker hose which provides on-demand irrigation of a treated plot of soil. A central passageway accommodates rainwater which exceeds the capacity of the collection system.
