Removable Goggle Retention Device with Buoyant Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Swimmers frequently lose their goggles due to accidental leaving or sinking, leading to costly replacements, especially for high-end or custom models, and existing retention devices are not suitable for goggles or do not allow for removable attachment to both goggles and other objects.
Innovation Solution
A lightweight, removable device that attaches to goggles and another object, such as a pool bag or keychain, using fastening regions and elongated flexible members to secure the goggles and keep them afloat, featuring buoyant materials and adjustable configurations to prevent loss and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a retention device is made removable and versatile to attach to both goggles and other objects, then adaptability is improved, but device complexity increases
Solution Approach 1:
The retention device is divided into separate modular components: a first portion that attaches to goggles and a second portion that attaches to objects like pool bags or keychains. These segments can be connected or used independently, providing versatility while maintaining simple individual components.
Solution Approach 2:
The device is designed with universal attachment capabilities that allow it to function with multiple types of objects - goggles, pool bags, keychains, and other swim-related items - through standardized fastening mechanisms that can interface with different objects.
2Reliability
If the device uses buoyant materials to keep goggles afloat, then reliability is improved, but weight increases
Solution Approach 1:
The device incorporates buoyant materials that provide upward floating force to counteract the weight of the goggles and device components, ensuring the goggles remain afloat and visible in water without requiring additional heavy counterweights.
Solution Approach 2:
The buoyancy-to-weight ratio of the device is optimized by selecting materials and configurations that provide sufficient buoyant force relative to the total weight, ensuring reliability while minimizing overall weight through efficient material selection.
3Ease of operation
If the device is made lightweight for easy attachment and removal, then ease of operation is improved, but strength may be compromised
Solution Approach 1:
The device utilizes flexible, lightweight materials that can be easily manipulated for attachment and removal operations, while the flexible nature of these materials allows them to withstand the forces encountered during swimming without compromising strength.
Solution Approach 2:
The attachment mechanisms are designed to be dynamically adjustable, allowing easy attachment and removal operations while maintaining secure connection during use. The flexibility and adaptability of the components enable simple operation without sacrificing connection strength.
