Solution Overview

Problem

Firefighting accessories often face structural integrity issues due to heavy and lengthy designs, leading to stress on connection points and difficulties in accessing fire seats, especially in exterior-only fire suppression scenarios.

Innovation Solution

A support sleeve designed to enhance the structural integrity of firefighting accessories by providing a tube with threaded connectors that align and secure other firefighting accessories, distributing stress and preventing failure at connection points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If firefighting accessories are made heavy and lengthy to improve durability and accessibility, then structural strength is improved, but stress on connection points increases leading to potential failure

Engineering Contradiction:
Improvestructural strengthVSAvoidconnection point reliability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The support sleeve acts as an intermediary component between two firefighting accessories. It is inserted into the first accessory and extends to support the second accessory, distributing the stress of heavy and lengthy configurations across multiple connection points and preventing failure at any single connection point.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If firefighters conduct exterior only fire suppression to improve safety, then exposure to hazardous conditions is reduced, but extinguishment time increases

Engineering Contradiction:
Improveexposure to hazardous conditionsVSAvoidextinguishment time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The extension assembly with support sleeve enables exterior-only fire suppression by extending the reach of fire suppression equipment in the spatial dimension, allowing firefighters to access and treat the seat of the fire from outside the structure, thereby reducing exposure to hazardous conditions while maintaining effective extinguishment capability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If threaded connectors are used to connect firefighting accessories, then ease of connection is improved, but alignment precision deteriorates under stress

Engineering Contradiction:
Improveease of connectionVSAvoidalignment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The support sleeve serves as a mediator between threaded connectors, providing a stable structure that maintains alignment precision even when subjected to the stress of heavy and lengthy configurations. It ensures that threaded connectors remain properly aligned during connection and under operational load.

Inventive Principle:
Principle #24Intermediary (Mediator)

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 support sleeve effectively stabilizes connections under high-pressure conditions, allowing for more efficient and safer fire suppression operations by reducing the time needed to extinguish fires and minimizing exposure to hazardous conditions.

Implementation Method 1

The first end of the tube is configured to frictionally fit within a first firefighting accessory having threaded connectors
