Elastomeric Sport Goggle Strap with Ponytail Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sport goggle straps often interfere with ponytails, are difficult to adjust, and provide inadequate support, especially for girls with longer hair, as they are complex and not easily adaptable to different ponytail locations.
Innovation Solution
A sport goggle strap made of elastomeric material with connection members such as hook and loop fasteners that allow for adjustable length and secure attachment to the goggle frames, reducing slippage and interference with hair, featuring a unitary piece design with an elongated opening and cooperating elements for easy adjustment and secure fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional thin rubber band straps are used, then the goggles can be held securely on the user's head, but the straps interfere with ponytails and provide inadequate support
Solution Approach 1:
The strap is divided into multiple segments: a headband portion, side portions with openings, and connection members. This segmentation allows the strap to accommodate ponytails by providing space for hair passage while maintaining secure goggle attachment through distributed connection points.
Solution Approach 2:
Different portions of the strap have different properties optimized for their specific functions. The headband portion is designed to fit comfortably on the head, the side portions include openings for ponytail accommodation, and the connection members provide secure attachment to the goggle frames. Each segment's local characteristics address specific requirements.
2Adaptability or versatility
If adjustable buckles and multiple straps are used to accommodate different ponytail placements, then the strap can adapt to various hair styles, but the device becomes complex with multiple loops and buckles
Solution Approach 1:
The strap design incorporates universal features that work with various ponytail placements without requiring multiple different strap configurations. The openings in the side portions and the flexible headband allow a single strap design to accommodate different hair styles and ponytail positions, eliminating the need for multiple specialized straps.
Solution Approach 2:
The strap includes flexible and adjustable elements that can dynamically adapt to different configurations. The headband portion can flex and the connection members can be positioned at different locations, allowing the same strap to accommodate various ponytail placements without requiring multiple fixed-configuration straps.
3Ease of operation
If a flat nylon disc ponytail holder is used, then the strap can hold the ponytail, but the stiff edge can slide on the user's hair and cause discomfort
Solution Approach 1:
The ponytail holder is designed with a curved or contoured shape that follows the natural curvature of the head and hair, rather than a flat disc shape. This curvature prevents the holder from sliding on the hair while maintaining secure ponytail attachment, and the rounded edges eliminate the discomfort caused by stiff flat edges.
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 strap provides comfortable and secure support for sport goggles without requiring frequent adjustments, accommodating various ponytail placements and minimizing interference with hair, offering a simpler and more effective solution than existing designs.

AI summary
A sport goggle strap for affixing sport goggles to the face of a user with first and second end portions, each having a connection member for attaching the first and second end portions to opposite sides of sports goggles, and an intermediate portion between the first and second end portions having an elongated opening disposed substantially in line between the first and second end portions. The first end portion, second end portions and the intermediate portion are comprised of a unitary piece of an elastomeric material, and preferably neoprene.
