Collar Stowage Pouch for Foldable Chinstrap Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighter's chinstraps often dangle and interfere with visibility when not in use, posing safety risks by exposing the face and neck regions to intense heat.
Innovation Solution
A foldable chinstrap system with a stowage pouch integrated into the collar, where one end is stitched within the pouch and the other end is attached via hook-and-pile to the collar, allowing easy attachment and detachment for use and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the chinstrap is attached to the collar, then the chinstrap provides protection, but it dangles and interferes with visibility when not in use
Solution Approach 1:
The chinstrap is nested within the collar structure when not in use. The collar contains a stowage pouch that receives the chinstrap, allowing the chinstrap to be stored within the collar's structure rather than dangling externally. This nesting solution eliminates visibility interference while maintaining protection capability when the chinstrap is deployed.
2Object-affected harmful factors
If the chinstrap is stored within the collar, then visibility is enhanced, but the chinstrap must be easily accessible for quick deployment
Solution Approach 1:
The chinstrap is pre-positioned within the collar's stowage pouch in a ready state. The collar structure includes a predetermined stowage location that accommodates the chinstrap, allowing for rapid deployment by simply removing the chinstrap from its pre-positioned location. This preliminary arrangement ensures both visibility enhancement during storage and ease of quick deployment when needed.
3Device complexity
If the chinstrap is made foldable with attachment points, then it can be stored compactly, but the attachment mechanism must be secure and reliable
Solution Approach 1:
The chinstrap incorporates self-retaining attachment features that allow it to be securely fastened to the collar without requiring additional fastening mechanisms. The chinstrap includes attachment points that automatically engage with the collar's stowage structure, providing secure retention while maintaining compact foldable storage configuration. This self-service attachment eliminates the need for separate fastening devices.
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
Prevents chinstrap dangling, enhances visibility, and ensures safe neck and face protection by allowing convenient storage and quick deployment of the chinstrap.
Implementation Method 1
The second end of the foldable chinstrap is removably attached to the interior surface of the first section in the folded configuration via a hook-and-pile attachment

AI summary
A protective apparel having a collar is disclosed. The collar defines a stowage pouch. The protective apparel comprises a foldable chinstrap having a first end and a second end. The first ends of the foldable chinstrap is disposed within the stowage pouch and the second end is attached to an interior surface of the collar in a folded configuration. The foldable chinstrap transitions from the folded configuration to an unfolded configuration when the second end of the foldable chinstrap is separated from the interior surface of the collar and extended to attach to an exterior surface of the collar.
