Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with conductive hearing loss, particularly those with chronic ear inflammation, malformed ears, or single-sided deafness, often cannot benefit from traditional hearing aids and are not suitable candidates for cochlear implants, as these devices either damage residual hair cells or are unsuitable for bone conduction.
Innovation Solution
A bone conduction device with a user interface that allows users to customize settings and access data, featuring a sound input system, electronics module with a sound processor, transducer for generating vibrations, and a user interface for altering control settings, enabling effective sound perception through skull vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional hearing aids are used for conductive hearing loss, then air conduction amplification is provided, but the device cannot be worn by individuals with chronic ear inflammation, malformed ears, or single-sided deafness
Solution Approach 1:
The patent introduces bone conduction as an intermediary transmission path between sound and the cochlea, bypassing the problematic outer and middle ear structures. The bone conduction device transmits sound vibrations directly through the skull bones to the inner ear, serving as a mediator that avoids the inflamed or malformed ear canal while still delivering auditory signals effectively.
2Reliability
If cochlear implants are used for profound hearing loss, then direct electrical stimulation of the cochlea is provided, but residual hearing is destroyed due to hair cell damage
Solution Approach 1:
The patent applies partial action by providing only the necessary degree of stimulation through bone conduction without the excessive invasive intervention of cochlear implants. Bone conduction delivers sufficient auditory stimulation for many hearing loss types while avoiding the complete destruction of hair cells that occurs with electrode insertion, thus providing adequate hearing perception without the harmful side effects.
3Ease of operation
If hearing aids are designed with more control features, then user customization capability is improved, but device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the hearing device receives input from the user environment and automatically adjusts its output characteristics. The device monitors acoustic conditions, user responses, and environmental factors, then dynamically modifies amplification levels and frequency responses without requiring complex manual controls, thereby maintaining ease of operation while reducing apparent device complexity.
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
Enhances hearing by converting sound signals into mechanical vibrations for the skull, allowing users to adjust settings for improved sound perception, accommodating various hearing impairments beyond traditional hearing aid limitations.
Implementation Method 1
a transducer configured to generate, based on the drive signals, vibration signals resulting in perception by the recipient of the received sound
Implementation Method 2
Bone conduction devices rely predominantly on vibration of the bones of the recipients skull to provide acoustic signals to the cochlea. This vibration is then transferred to the bone structure of the skull, causing vibration of the recipient's skull. This skull vibration results in motion of the fluid of the cochlea.
