Firefighting Support Sleeve Stress Distribution
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
3Ease of operation
If threaded connectors are used to connect firefighting accessories, then ease of connection is improved, but alignment precision deteriorates under stress
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.
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
Data Source
AI summary
A support sleeve for a firefighting accessory is provided. A tube having a first end and a second end is configured to frictionally fit at the first end within a first firefighting accessory. The second end of the tube allows for easy alignment and a secure attachment of the first firefighting accessory to a second firefighting accessory.
