Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carrying systems for breathing apparatus are cumbersome, impede movement, and lack comfort and safety features, particularly for firefighters working in hostile environments.
Innovation Solution
A carrying system with a contoured backplate made of plastics material that provides impact protection, is adjustable, and includes high-quality padding, along with easy attachment and removal mechanisms for the air cylinder and hoses, ensuring proper load distribution and user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional harness with rigid structure is used to carry the air cylinder, then the air cylinder is securely held, but the user's movement is impeded and comfort is reduced
Solution Approach 1:
The backplate is constructed from flexible materials including foam layers and fabric covers that can bend and conform to the user's back movements, allowing the air cylinder to be securely held while accommodating natural body motion during firefighting operations
Solution Approach 2:
The harness incorporates adjustable straps and flexible connections that allow dynamic adaptation to different user sizes and movement patterns, enabling the system to maintain secure holding while moving with the user's body during various operational positions
2Object-affected harmful factors
If a rigid backplate is used to provide impact protection, then safety is improved, but the ability to flex with user movement is reduced
Solution Approach 1:
The backplate uses composite construction with foam cushioning layers sandwiched between fabric covers, combining the impact-absorbing properties of foam with the durability and flexibility of fabric, achieving both protection and adaptability
Solution Approach 2:
The padding is strategically positioned in specific areas of the backplate where impact forces are most likely to occur, providing enhanced protection at critical locations while maintaining flexibility in other areas for optimal movement
3Stability of the object's composition
If the air cylinder is securely strapped to the backplate, then load stability is improved, but the center of gravity may be misaligned causing user discomfort
Solution Approach 1:
The harness features adjustable strap lengths and positioning mechanisms that allow the air cylinder to be mounted at different heights and positions on the backplate, enabling users to optimize the center of gravity alignment with their body for improved comfort and reduced fatigue
4Adaptability or versatility
If the harness structure is made complex to accommodate various features, then functionality is improved, but ease of manufacture and maintenance are reduced
Solution Approach 1:
The harness is divided into modular components including the backplate, shoulder straps, waist belt, and air cylinder mounting system, each manufactured separately and then assembled, simplifying the manufacturing process for each component while maintaining overall functionality
Solution Approach 2:
The backplate serves multiple functions simultaneously: it provides impact protection through padding, supports the air cylinder through integrated mounting points, and distributes weight across the user's body, reducing the need for separate specialized components
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 system enhances user comfort, reduces fatigue, and improves safety by allowing flexible movement while securely holding the air cylinder, ensuring correct center of gravity and easy maintenance through washing.
Implementation Method 1
provide impact protection to a user during use by at least partially absorbing and/or dispersing impact forces
Implementation Method 2
deform resiliency in response to external forces imposed by bending and/or twisting of a user during use and return substantially to its predetermined shape

AI summary
A carrying system is provided for use with breathing apparatus. The carrying system includes a backplate and a plurality of straps adapted to hold the backplate on the back of a user when the carrying system is worn. The backplate includes at least one plate of a plastics material. The at least one plate having a predetermined shape and the at least one plate being adapted to provide impact protection to a user during use by at least partially absorbing and/or dispersing impact forces, and to deform resiliency in response to external forces imposed by bending and/or twisting of a user during use and return substantially to its predetermined shape when not subjected to an external force.
