Soft Gel Ear Guard with Stretchable Cap for Water Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water ear guards with foam materials lack a secure fit and fail to effectively protect the inner and outer ear from water and harsh chemicals, which can cause irritation or burns.
Innovation Solution
A device featuring an ear canal-shaped soft gel plug with a clear, stretchable cap that covers the entire ear, providing resistant protection against water and harsh chemicals by forming a secure seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foam material is used for ear canal protection, then the device is inexpensive and easy to manufacture, but it does not provide a secure fit and fails to protect the inner ear effectively
Solution Approach 1:
The patent changes the material parameter from foam to soft gel, which fundamentally alters the protective properties. The soft gel material provides a secure fit and effective protection against water and chemicals, directly resolving the reliability issue while maintaining ease of manufacture through simple molding processes
Solution Approach 2:
The device combines soft gel material with a clear cap structure, creating a composite protection system. The soft gel provides the secure fit and chemical resistance, while the clear cap adds structural integrity and visual clarity, together achieving superior protection without significantly increasing manufacturing complexity
2Reliability
If a secure fit is achieved with soft gel material, then protection effectiveness is improved, but the device complexity increases
Solution Approach 1:
The device is segmented into two distinct components: the soft gel ear canal plug and the clear cap. This segmentation allows each component to be optimized independently - the soft gel provides secure fit and protection, while the clear cap provides structural support and visual clarity - without overall increasing device complexity
Solution Approach 2:
The soft gel material functions as a flexible shell that conforms to the ear canal shape, providing a secure fit. This flexible shell approach simplifies the overall structure compared to rigid fittings, as the soft gel naturally adapts to the anatomy while maintaining protection effectiveness
3Object-affected harmful factors
If foam material is used, then manufacturing is simple, but protection against water and chemicals is insufficient
Solution Approach 1:
Changing the material parameter from foam to soft gel fundamentally improves protection against water and chemicals. The soft gel material provides superior resistance properties while maintaining manufacturing simplicity through standard molding techniques, directly addressing the protection deficiency without sacrificing ease of manufacture
