Quick Release Slide Clip for SCBA Waist Belt Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighter SCBA systems often become entangled or cumbersome, hindering mobility and safety when quickly disconnected from waist belts, and existing quick release systems do not efficiently allow for simultaneous removal of the SCBA while retaining the waist belt for continued use.
Innovation Solution
A quick release apparatus comprising a belt connection apparatus, an SCBA frame connection apparatus, and a coupling apparatus with rapid release members that enable rapid disconnection of the SCBA from the waist belt, allowing the SCBA to be removed while leaving the waist belt and its accoutrements in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a quick release system is implemented to rapidly disconnect SCBA from waist belt, then mobility and safety are improved, but the system complexity increases
Solution Approach 1:
The quick release system is divided into separate functional components: a belt connection apparatus attached to the waist belt, an SCBA frame connection apparatus attached to the SCBA frame, and a coupling apparatus with rapid release members. This segmentation allows each component to perform its specific function independently, enabling rapid disconnection while maintaining overall system manageability
Solution Approach 2:
The coupling apparatus with rapid release members is extracted as a distinct mechanism that can be independently operated to disconnect the SCBA from the waist belt. This extraction allows the quick release function to be activated without affecting the integrity of the belt or SCBA frame themselves
2Loss of time
If the SCBA is quickly disconnected from the waist belt, then egress speed is improved, but the reliability of connection may be compromised
Solution Approach 1:
The coupling apparatus is pre-configured with rapid release members that are positioned and prepared for immediate activation. The belt connection apparatus and SCBA frame connection apparatus are pre-attached to their respective components, so that when the rapid release members are activated, the disconnection occurs immediately without requiring additional manipulation or steps
Solution Approach 2:
The coupling apparatus serves as an intermediary mechanism between the belt connection apparatus and the SCBA frame connection apparatus. It provides a controlled interface that maintains secure connection during normal use while enabling rapid disconnection when activated, thus mediating between the conflicting requirements of connection reliability and quick release capability
3Adaptability or versatility
If the waist belt is designed to remain on the wearer during SCBA removal, then tool access is maintained, but the device complexity increases
Solution Approach 1:
The system is segmented into two independently retainable components: the waist belt with its attached tools and accoutrements, and the SCBA unit. The quick release mechanism allows these segments to be separated while each remains intact and functional on its own, enabling the wearer to retain tool access via the belt while removing the SCBA
Solution Approach 2:
The waist belt is designed to serve multiple functions: it provides structural support for the SCBA when connected, serves as a safety harness component, and functions as a tool carrier when the SCBA is removed. The quick release system enables the belt to transition between these functions without requiring modification or additional equipment

AI summary
A quick release apparatus for rapid disconnection of a waist belt from a self-contained breathing apparatus support frame, including frame connectors disposed on a lumbar support pad. The frame connectors and inserted through horizontal slots on the SBCA support frame and present an aperture for insertion of slide clips that tether the SCBA support frame to the lumbar support pad. The support pad, in turn, may be removably attached to a trucker's belt or integrated therein. In an emergency, the slide clips may be rapidly removed with a simple pull to effect a full and compete release of the SCBA support frame from the waist belt while leaving the waist belt and its accoutrements on the user.
