Moldable Ear Insert for Custom Fit and Waterproof Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal audio equipment, such as earbuds, suffer from structural and ergonomic disadvantages like dislodging during activities, discomfort, and lack of a secure custom fit, with existing solutions being either fragile or requiring heat to mold.
Innovation Solution
The use of a moldable material, such as silicone or wax, that remains deformable at room temperature, allowing for a custom fit within the ear concha without curing, integrated with electronics to provide a secure, comfortable, and waterproof ear insert that adjusts to fit each user's ear structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If hard plastic shells are used in earbuds, then structural strength is improved, but comfort and secure fit are worsened
Solution Approach 1:
The patent applies this principle by using a flexible, moldable material (such as putty, clay, or other deformable substances) to create a custom-fit earbud shell that conforms to the user's ear canal. This flexible material provides both structural integrity and a personalized fit, resolving the contradiction between hard plastic strength and comfort.
Solution Approach 2:
The patent applies this principle by having the user mold the earbud shell to their ear canal in advance of use. The user shapes the flexible material around their ear canal to create a custom fit, which then provides both structural strength and comfort during subsequent use.
2Ease of operation
If moldable material is used to create custom fit, then comfort and secure fit are improved, but structural strength is worsened
Solution Approach 1:
The patent applies this principle by combining a flexible moldable material with a rigid structural component. The flexible material provides custom fit and comfort, while the rigid component (such as a plastic or metal frame) provides structural strength. This composite approach resolves the contradiction between moldability and strength.
3Manufacturing precision
If existing molding methods are used, then custom fit is achieved, but heat application is required which may damage components
Solution Approach 1:
The patent applies this principle by changing the temperature parameter of the molding process. Instead of using high heat that could damage electronic components, the patent uses body temperature or ambient temperature molding with materials that are sufficiently moldable at these lower temperatures, thus achieving custom fit without heat damage.
4Stability of the object's composition
If secure fit is achieved through existing methods, then dislodging is prevented, but device complexity and weight increase
Solution Approach 1:
The patent applies this principle by dividing the earbud into separate functional components: a flexible moldable shell that provides custom fit, a rigid structural component that provides strength, and electronic components. This segmentation allows each part to be optimized for its specific function without adding unnecessary complexity or weight to the overall device.
