Solution Overview

Problem

Firehoses often suffer wear and damage due to snagging on obstructions, friction with the ground, and impact from hard surfaces, leading to broken couplings and torn hoses.

Innovation Solution

A hose coupling protection apparatus with a cover assembly that provides a smooth outer covering around the couplings, reducing snagging opportunities and lifting hoses off the ground, while also acting as a buffer against impacts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If firehoses are dragged across ground surfaces for extended range, then the hoses can reach distant fires, but the couplings and hose material suffer extensive wear and damage

Engineering Contradiction:
Improveextended rangeVSAvoidcoupling integrity
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The patent introduces a protective coupling cover as an intermediary element between the coupling and the harsh environment. This cover shields the coupling from direct contact with ground surfaces, obstructions, and debris, thereby preventing wear and damage while allowing the hose to maintain extended range capability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the hose couplings are exposed without protection, then the structure remains simple, but the couplings snag on obstructions and become immobilized

Engineering Contradiction:
Improvecoupling structureVSAvoidhose mobility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The protective coupling cover acts as a mediator that smooths the interface between the coupling and surrounding environment. By providing a smooth outer surface, it prevents snagging on obstructions while maintaining hose mobility and ease of operation

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the couplings are dropped onto hard surfaces during deployment, then quick connection is achieved, but the couplings suffer impact damage

Engineering Contradiction:
Improveconnection speedVSAvoidcoupling strength
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The protective coupling cover provides beforehand cushioning by absorbing and distributing impact forces before they reach the coupling. This pre-protection mechanism prevents damage during rapid deployment operations where couplings may be dropped onto hard surfaces

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A hose coupling protection apparatus includes a cover assembly constructed and arranged to install around a set of hose couplings which connects a first hose and a second hose. The cover assembly provides a smooth outer covering around the set of hose couplings when the cover assembly is installed around the set of hose couplings. In some arrangements, the cover assembly includes a first casing section and a second casing section, the first casing section and the second casing section being constructed and arranged to install around the set of hose couplings when fitted around the set of hose couplings and brought together into engagement (e.g., via snap-fit features).
