Floating Harness for Firefighter Turnout Gear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighters face challenges with bulky personal fall protection equipment (PFE) that is difficult to don in emergency situations, and existing safety harnesses integrated into turnout gear are cumbersome and hard to adjust.
Innovation Solution
A floating harness system that includes a waist strap, leg straps, and support straps slideably attached to the waist strap, integrated into firefighter trousers with a guide and retainer system for easy adjustment and secure attachment, allowing the support straps to move vertically without altering the waist strap position, providing comfort and ease of use while maintaining safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional personal fall protection equipment (PFE) is worn by firefighters, then safety is improved, but the equipment becomes bulky and difficult to don in emergency situations
Solution Approach 1:
The patent combines the safety harness with the firefighter's turnout suit by integrating the waist strap into the trousers and the support strap into the coat. This merging eliminates the need for separate PFE equipment, making the safety system part of the standard uniform that firefighters already wear, thus improving ease of donning while maintaining safety.
Solution Approach 2:
The integrated harness system serves multiple functions: it provides fall protection, is built into the standard turnout suit structure, and can be used in various emergency situations. The waist strap integrated into trousers and support strap integrated into coat create a universal safety system that works with the existing firefighting ensemble.
2Ease of operation
If safety harness is integrated into turnout gear, then ease of operation is improved, but the harness becomes cumbersome and hard to adjust
Solution Approach 1:
The support strap is designed to be dynamically adjustable within the coat structure. The strap can move vertically through the coat and be adjusted by the firefighter as needed. This dynamic design allows the harness to adapt to different body positions and emergency situations while remaining integrated into the turnout gear.
Solution Approach 2:
The harness is segmented into distinct components: the waist strap integrated into the trousers, the support strap integrated into the coat, and the leg straps. This segmentation allows each component to be independently adjusted and positioned, simplifying the overall adjustment process while maintaining integration with the turnout suit.
3Stability of the object's composition
If support straps are fixed to waist strap, then structural stability is improved, but the harness becomes constricting and uncomfortable
Solution Approach 1:
The support strap is designed to slide vertically through the coat structure rather than being fixed at a single point. This dynamic configuration allows the strap to move with the firefighter's body movements, providing structural stability when needed while preventing constriction and discomfort during normal activity.
Solution Approach 2:
The position of the support strap relative to the waist strap can change dynamically. The strap can be positioned at different vertical locations depending on the situation, allowing the harness to maintain structural stability during rescue operations while being comfortable during normal wear and movement.
