Rigging Hose Housing Gutter Drain for Marine Water Intrusion

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing rigging hose assemblies for marine vessels allow water intrusion, leading to corrosion and damage of electrical components, as they fail to effectively divert and expel fluid from the hose housing, resulting in water entering the vessel's interior.

Innovation Solution

A rigging hose housing with a radial mounting plate, outer and inner cylindrical walls, and a gutter system that terminates in a drain hole, which collects and expels fluid, while providing structural support and secure mounting to the vessel, minimizing water intrusion paths and enhancing corrosion resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional rigging hose housing without a gutter system is used, then the structure is simpler, but water intrusion occurs leading to corrosion and damage of electrical components

Engineering Contradiction:

Improvecorrosion resistanceVSAvoidhousing structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The housing is segmented into functional zones using an inner cylindrical wall and outer cylindrical wall that form a gutter system. This segmentation creates distinct areas for fluid collection and drainage, separating the protective function from the structural function, thereby improving corrosion resistance without excessive complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The gutter system acts as an intermediary structure between the hose assembly and the housing environment. It mediates fluid management by collecting and directing water away from electrical components, providing protection while maintaining a manageable structural addition.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If no fluid drainage path is provided, then the housing structure is simpler, but fluid accumulation leads to water entering the vessel's interior

Engineering Contradiction:

Improvewater intrusion preventionVSAvoiddrainage system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The drainage function is extracted as a separate, dedicated feature through the drain hole provision. Instead of attempting to manage fluid accumulation within the main housing body, the design extracts the drainage need into a specific, simple outlet feature that actively removes water from the system.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of trying to prevent water from entering the housing entirely, the design inverts the approach by providing a controlled exit path for water. The drain hole allows water that enters the gutter system to be actively expelled from the housing, preventing accumulation and interior water intrusion.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If the hose housing lacks a gutter system, then manufacturing is simpler, but corrosion and damage to electrical components occur

Engineering Contradiction:

Improveelectrical component protectionVSAvoidhousing fabrication

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The gutter system merges the fluid management function with the existing housing structure. By integrating the inner and outer cylindrical walls into the housing assembly, the design combines protection and drainage functions within a unified structural framework, improving component protection while maintaining manufacturing feasibility.

Inventive Principle:

Principle #5Merging (Combining)

4Strength

If multiple mounting holes are provided in the radial mounting plate, then mounting security is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvemounting securityVSAvoidmounting plate fabrication

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The radial mounting plate serves multiple functions: it provides structural support for the housing and simultaneously offers multiple mounting holes for secure installation. This multi-functionality allows a single component to address both structural integrity and mounting security needs, improving strength without proportionally increasing manufacturing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A rigging hose housing is provided to couple a rigging hose to a marine vessel. The rigging hose housing includes a radial mounting plate; an outer cylindrical wall extending perpendicularly from the radial mounting plate a first height above a bottom surface of the radial mounting plate; an inner cylindrical wall extending perpendicularly from the radial mounting plate a second height above the bottom surface of the radial mounting plate; and a gutter formed between the inner cylindrical wall and the outer cylindrical wall. The gutter terminates in a drain hole formed in the outer cylindrical wall. The drain hole is configured to permit the expulsion of fluid collected in the gutter from the rigging hose housing.
