Goggle Strap Retention via Nested Cage and Outrigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sport goggles face challenges with bulky designs that lead to reduced peripheral vision and increased impact risks due to inadequate strap-to-frame coupling, which can result in strap failure under stress.
Innovation Solution
The use of a goggle frame with outriggers and cages that securely couple an elastic band to the frame, providing a stronger and more compact attachment system through protrusions and fasteners, allowing for improved strap retention and reduced bulkiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a robust strap-to-frame coupling system is used, then strap retention strength is improved, but goggle bulkiness increases
Solution Approach 1:
The cage is nested within the outrigger structure, with the elastic band nested within the cage. This nested arrangement allows the strap retention system to be integrated into the existing goggle frame geometry, providing robust coupling strength without adding external bulk to the goggle assembly.
Solution Approach 2:
The strap retention system is segmented into distinct functional components: the outrigger (structural support), the cage (band holder), and the elastic band (retention element). This segmentation allows each component to be optimized for its specific function while maintaining overall compactness, as each segment contributes differently to the total strength-to-bulk ratio.
2Reliability
If a robust strap-to-frame coupling system is used, then reliability under stress is improved, but device complexity increases
Solution Approach 1:
The cage structure provides beforehand cushioning by absorbing and distributing stress forces before they can concentrate on single attachment points. The geometric design of the cage with its multiple walls and the elastic band's natural elasticity create a cushioning effect that protects the coupling system from failure under sudden impacts or sustained loads.
Solution Approach 2:
The coupling system employs composite construction combining rigid materials (outrigger and cage structure) with flexible materials (elastic band). This composite approach allows the system to simultaneously achieve high reliability under stress through the rigid framework while managing force distribution through the flexible band, creating a balanced coupling system that is reliable without being overly complex.

Function Achieved in This Case
This configuration enhances the durability and comfort of sport goggles by providing a stronger strap-to-frame coupling, reducing bulkiness, and improving peripheral vision while withstanding forces without failure.
Implementation Method 1
The elastic band may include a first end and a second end. The first cage may be disposed within the first outrigger opening. The second cage may be disposed within the second outrigger opening. Each of the first and second cages may include a band opening and at least one protrusion disposed within the band opening.

AI summary
A goggle is described herein. The goggle can include a cage configured to receive an elastic band and be disposed within an opening of the goggle frame. The cage can be made from a stronger material than the goggle frame itself and, thus, allow for a stronger connection of the elastic band to the goggle frame than traditional techniques. The cage can also include features to more securely hold the elastic band within the cage and the cage within the opening of the goggle frame.
