Earpiece Foam Sizer with Integrated Cleaning and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a shaping apparatus to cleanly shape foam earpieces for insertion into the ear canal and for an all-in-one apparatus to store and shape/size foam earpieces effectively.
Innovation Solution
An earpiece-foam shaping system comprising a bottom portion for storing earpieces, a cap for removably coupling to the bottom portion, and a sizer configured to compress the foam portion to fit inside a user's ear, with features like a center post for centering and barbs for holding the foam in place, and a cleaning tool for removing unwanted material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual rolling is used to shape foam earpieces, then the foam can be shaped, but the foam is exposed to dirt and contamination
Solution Approach 1:
The patent introduces a sizing tool as an intermediary device between the user and the foam earpiece. The tool provides a controlled environment with cleaning brushes that contact the foam during shaping, preventing direct exposure to dirt while maintaining ease of operation through simple insertion and twisting motions
Solution Approach 2:
The sizing tool incorporates cleaning brushes that automatically contact and clean the foam earpiece during the shaping process. The tool serves itself by integrating the cleaning function into the shaping mechanism, eliminating the need for separate cleaning steps and preventing dirt exposure throughout the entire process
2Adaptability or versatility
If a separate shaping tool is used, then the foam can be shaped cleanly, but storage and shaping require separate devices
Solution Approach 1:
The patent combines multiple functions into a single sizing tool: foam shaping, foam cleaning, and storage. The sizing tool integrates cleaning brushes within its structure and includes a storage compartment, eliminating the need for separate shaping and cleaning devices while maintaining simplicity through unified design
3Manufacturing precision
If the foam is compressed manually, then it can be sized, but the shape may be inconsistent
Solution Approach 1:
The sizing tool features a tapered bore with specific geometric dimensions that provide localized compression zones. The tapered structure creates progressive compression from the wide end to the narrow end, ensuring consistent shape and size without requiring complex manual manipulation, achieving precision through simple insertion and twisting actions
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 system efficiently shapes and sizes foam earpieces, ensuring proper fit and hygiene by eliminating the need for manual rolling, which can expose the foam to dirt, and provides a convenient storage solution.
Implementation Method 1
a sizer configured to receive the foam portion in order to compress the foam portion such that the foam portion is configured to fit inside an ear of a user
