Non-Surgical Bone Conductor Plate Protrusion for Vibration Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-surgical bone conductive hearing solutions face challenges in achieving efficient vibration transfer and stability, often resulting in inconsistent pressure on the skin, which can lead to dampening of sound and potential device displacement.
Innovation Solution
A connector plate with a protrusion configured to maintain constant contact with the skin, integrated as a single part with the adhesive pad, ensures direct and efficient vibration transfer by providing a rigid surface for sound energy transmission, while the adhesive pad's design allows for breathability and weight distribution through strategically placed legs or fingers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a non-surgical bone conductive device uses a flat plate structure attached to the skin, then the device is simple to manufacture and apply, but the vibration transfer efficiency is reduced due to inconsistent pressure and potential displacement
Solution Approach 1:
The patent applies curvature by replacing the flat plate structure with a domed or convex surface that protrudes from the plate. This curved surface maintains consistent contact pressure with the skull bone, preventing displacement and improving vibration transfer efficiency while remaining manufacturable as an integrated feature of the plate structure
2Reliability
If a non-surgical bone conductive device uses a rigid connector plate, then the vibration transfer is improved, but the device may cause discomfort or damage to the skin due to concentrated pressure
Solution Approach 1:
The patent applies local quality by creating a localized domed protrusion on the connector plate that concentrates the rigid surface only at the specific contact point with the skull bone, while the rest of the plate maintains flexibility or uses adhesive attachment to distribute pressure elsewhere, thus improving vibration transfer at the contact point while minimizing skin discomfort
3Stability of the object's composition
If a non-surgical bone conductive device uses a connector plate with increased surface area, then the stability on skin is improved, but the weight of the device increases
Solution Approach 1:
The patent applies curvature by using a domed protrusion that increases the effective contact surface area with the skull bone through its three-dimensional curved geometry, rather than expanding the overall plate area. This provides enhanced stability and consistent pressure distribution without significantly increasing the device's overall weight

Function Achieved in This Case
This design enhances the efficiency of sound vibration transfer, minimizes dampening, and maintains the device's stability on the skin, providing improved sound perception and comfort for hearing-impaired individuals.
Implementation Method 1
The protrusion is configured to abut the skin of a skull when the plate structure is attached to the skin, thereby allowing a vibration transfer to the bone skull

AI summary
The disclosure relates to a plate structure of a non-surgical bone conductive device, configured to be attached to a part of the skin of the skull of a hearing impaired person. The non-surgical bone conductive device is designed such that an optimized vibration transfer is achieved, while at the same time allowing a sufficient leverage of the weight of the sound processor when the sound processor is connected to the plate structure.
