Solution Overview

Problem

Existing rain chain installation methods fail to securely attach and properly position rain chains relative to rain gutters, leading to water misdirection and potential erosion or damage, due to issues like oversized openings, water swirling out, and movement caused by wind or objects.

Innovation Solution

A rain chain installation kit featuring a gutter attachment unit with a tapered outlet tube and flange, combined with a sloped member that self-centers and supports the rain chain, ensuring accurate alignment and secure attachment to the gutter, preventing water from missing the chain even under external disturbances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rain chain is attached to a rain gutter using existing attachment methods, then the rain chain can be installed, but the rain chain may move off-center due to wind, people, or animals, causing water to miss the chain

Engineering Contradiction:
Improverain chain positioning stabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The installation kit includes a self-centering mechanism where the rain chain automatically centers itself on the outlet tube through gravity and geometry, eliminating the need for precise manual positioning during installation. The chain's weight and the tube's shape work together to maintain automatic centering

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The outlet tube is pre-installed in the gutter before the rain chain is attached. This preliminary positioning of the tube creates a stable, fixed reference point that guides the rain chain into proper alignment, preventing future displacement by external forces

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the gutter opening is larger than the rain chain's link or cup, then the rain chain can be easily installed, but much of the water will miss the rain chain at the top

Engineering Contradiction:
Improveinstallation easeVSAvoidwater direction accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The outlet tube serves as an intermediary component between the gutter opening and the rain chain. It funnels and concentrates the dispersed water flow from the large gutter opening into a focused stream that reliably engages with the rain chain, solving the mismatch between opening size and chain size

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If water is discharged directly from the gutter drain aperture, then the setup is simple, but water tends to swirl out and miss the rain chain, causing erosion and water damage

Engineering Contradiction:
Improveinstallation simplicityVSAvoidwater erosion and damage
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The outlet tube acts as a mediating structure between the gutter and rain chain, transforming the harmful swirling water discharge into a controlled, directed flow. The tube's geometry stabilizes the water stream and directs it precisely onto the rain chain, eliminating erosion and water damage while adding minimal complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A kit for installing a rain chain to a rain gutter includes a gutter attachment unit having an outlet tube extendable through a drain aperture of the rain gutter. A rain chain support is attachable to the outlet tube and includes a sloped member which aligns and self-centers a rain chain coupled thereto with the outlet tube such that rainwater exiting the outlet tube is directed onto the rain chain.
