Modular SCBA Backpack Chassis with Interchangeable Tank Cradles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-contained breathing apparatus (SCBA) systems require separate backpacks for different air cylinder configurations, leading to inefficiency when multiple configurations are needed.
Innovation Solution
A standardized chassis with a cradle receiving arrangement that allows for the secure attachment of various tank cradles, enabling a single backpack to accommodate different numbers and configurations of air cylinders using a common coupling mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate chassis and cradles are used for different air cylinder configurations, then each configuration can be securely accommodated, but the number of backpack units required increases
Solution Approach 1:
The patent implements a universal cradle receiving arrangement with standardized attachment features that can accommodate multiple types of cradles (single cylinder, twin pack, plurality of cylinders) using the same coupling mechanism. This multi-functional design allows a single backpack to serve multiple configurations, resolving the contradiction between secure accommodation and number of units required
Solution Approach 2:
The patent divides the backpack system into modular components: a fixed chassis with receiving arrangement, interchangeable cradles, and standardized coupling mechanisms. This segmentation allows different cradle configurations to be attached to the same backpack chassis, reducing the total number of backpack units needed while maintaining secure accommodation for each configuration
2Ease of manufacture
If multiple separate backpacks are provided for different configurations, then each configuration is optimized, but manufacturing and inventory complexity increases
Solution Approach 1:
The patent creates a universal chassis design with standardized cradle receiving arrangements that can accept multiple cradle types. This reduces device complexity by eliminating the need for entirely different backpack designs for each configuration, while still allowing optimization of each cradle type for its specific purpose
Solution Approach 2:
The patent merges multiple configuration capabilities into a single backpack chassis through the universal receiving arrangement. Instead of manufacturing separate optimized backpacks for each configuration, the system combines all configurations into one platform, reducing manufacturing and inventory complexity

AI summary
An SCBA backpack for air cylinders includes a chassis with a cradle receiving arrangement and a tank cradle for holding at least one air cylinder, wherein the tank cradle is removably secured to the chassis. Such an arrangement permits a variety of different tank cradles that may secure one or more cylinders but that are still compatible with a common backpack chassis.
