Aquatic Goggle Strap with Support Member and Friction Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aquatic goggles often experience issues with head straps sliding downward or upward, causing them to rest around the neck or fall off the head due to inadequate securing during swimming or diving.
Innovation Solution
The design incorporates a strap system with stretchable sections, an adjustment mechanism, friction coating, and support members to prevent positional adjustment, ensuring a secure fit by conforming to the user's head and maintaining stability through flared sections and engagement points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the head strap is made adjustable to fit different head sizes, then the adaptability is improved, but the positional stability deteriorates causing the strap to slide
Solution Approach 1:
The support member is pre-positioned within the strap to prevent sliding before it occurs during use. The flared section is built into the strap structure in advance to create friction resistance and mechanical interlocking, ensuring positional stability is maintained while preserving adjustability.
2Ease of operation
If the strap is made stretchable to accommodate head movements, then the comfort is improved, but the securing force deteriorates allowing the goggle to slip
Solution Approach 1:
The strap incorporates stretchable sections that change the physical parameters of the material, allowing elastic deformation to accommodate head movements while maintaining sufficient securing force through the elastic recovery property of the stretchable material.
3Ease of manufacture
If the strap structure is simplified for ease of manufacture, then the manufacturing cost is reduced, but the anti-sliding performance deteriorates
Solution Approach 1:
The strap is divided into distinct functional sections: stretchable sections for comfort, flared sections for friction-based anti-sliding, and support members for structural stability. This segmentation allows each section to be optimized for its specific function while maintaining overall manufacturing feasibility.
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 solution effectively secures the goggles to the head, preventing them from sliding or falling, providing improved stability and comfort during aquatic activities by accommodating different head sizes and maintaining a secure fit.
Implementation Method 1
the strap has a friction coating positioned on the internal surface of the strap
Implementation Method 2
the strap has a stretchable section
