Ski Hat Goggle Storage Pocket with Moisture Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headwear designs face difficulties in easily deploying and securing accessories like goggles or bandannas for face protection, achieving a snug fit, and preventing fogging of eyewear lenses due to heat and moisture transfer through porous materials.
Innovation Solution
Incorporating a storage pocket with Velcro attachments on the hat, allowing the accessory to be easily deployed and secured across the face, with a non-permeable layer to prevent moisture from reaching the eyewear lens, ensuring a clear view and secure fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the accessory is stored on the front portion of the hat, then it is readily accessible, but it causes fogging of the eyewear lens due to heat and moisture transfer
Solution Approach 1:
The accessory storage function is extracted from the front portion of the hat and relocated to the rear portion. This separation removes the source of heat and moisture (the accessory stored on front) from proximity to the eyewear lens, thereby preventing fogging while maintaining accessibility through the rear storage location and elastic strap deployment mechanism.
Solution Approach 2:
An elastic strap serves as an intermediary element between the accessory and the wearer's face. The strap allows the accessory to be deployed from rear storage to the desired position on the face without requiring the accessory to be permanently positioned on the front of the hat, thus preventing direct contact between heat/moisture sources and the eyewear lens.
2Ease of operation
If the accessory is manually pulled into position, then it can be adjusted to fit, but it is difficult and unwieldy to manipulate
Solution Approach 1:
The accessory is designed with an elastic strap that provides dynamic, flexible adjustment capabilities. The elastic material allows the accessory to be easily stretched and positioned by the wearer without requiring complex manipulation, while still achieving a secure and adjustable fit across different face sizes and shapes.
Solution Approach 2:
The elastic strap's physical properties (elasticity, flexibility) enable the accessory to adapt to different parameters of the wearer's face. By changing the strap's extension state, the accessory can be adjusted to various positions and tightness levels without complex manipulation mechanisms.
3Reliability
If the accessory is securely retained to the hat, then it prevents separation, but it makes deployment and retraction difficult
Solution Approach 1:
The retention system is segmented into two distinct functions: (1) secure attachment of the accessory to the hat body when not in use, and (2) easy deployment and retraction mechanisms. The elastic strap and pouch design separate these functions, allowing the accessory to be firmly held during storage while enabling simple one-handed deployment and retraction operations.
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
Enables easy deployment and secure retention of accessories, improves fit and prevents fogging of eyewear lenses, enhancing user safety and comfort during activities.
Implementation Method 1
heat and moisture from the wearer's forehead may pass through the porous material of the hat and reach the goggle's inner surface
Implementation Method 2
a goggle band may be securely retained to the upper or forehead portion of a ski hat

AI summary
Headwear in which a storage area or pocket is formed in one side of the hat portion where an accessory is stored in the pocket when not in use. The free end of the accessory can be removed from the pocket by the wearer and pulled across the wearer's face after which the free end of the accessory is detachably secured to an opposite side of the hat portion so that the accessory remains positioned over the wearer's face. After use, the free end of the accessory is detached from the hat portion and returned for storage in the pocket. The invention is described in an embodiment for use in a ski hat in which the accessory is a goggle. Also described is the provision of a non-permeable layer in the hat portion that prevents moisture from reaching the goggle to prevent it from fogging up during its use.
