Solution Overview

Problem

Traditional bone conduction hearing aids cause discomfort and skin irritation due to constant pressure and potential infections, while conventional earphones can lead to hearing loss from prolonged use.

Innovation Solution

A non-surgical bone conduction hearing system that attaches behind the ear using an adhesive member with mating components, converting audio signals into sound vibrations transmitted through the skull bone, allowing dual use as a hearing aid and audio device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional bone conduction hearing aids use spring arrangement to press vibrator against skull, then sound transmission is achieved, but headaches and skin irritation occur

Engineering Contradiction:

Improvesound transmissionVSAvoidheadaches and skin irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an adhesive member as an intermediary between the vibrator and the skull, eliminating the need for direct pressure contact. The adhesive member bonds the vibrator to the skull surface without requiring constant mechanical pressure, thus preventing headaches and skin irritation while maintaining effective sound transmission through bone conduction.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical spring pressure system with a chemical bonding system (adhesive). Instead of using mechanical force to maintain contact between the vibrator and skull, the adhesive creates a permanent or semi-permanent bond that eliminates the need for continuous pressure application, thereby resolving the discomfort issues.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If direct bone conductor uses permanent skin penetration for anchoring, then vibrations are directly transmitted, but skin infections may occur

Engineering Contradiction:

Improvevibration transmissionVSAvoidskin infections

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The adhesive member serves as a non-invasive intermediary that bonds the vibrator to the skull surface without penetrating the skin. This eliminates the risk of skin infections associated with permanent skin penetration while maintaining effective vibration transmission for bone conduction hearing.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts and eliminates the skin penetration anchoring mechanism from the system. By removing the need for surgical or semi-surgical anchoring, the invention avoids the associated infection risks while achieving reliable vibration transmission through alternative adhesive bonding methods.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If earphones are inserted directly into ear for audio listening, then music and audio can be heard, but inner ear damage and hearing loss may result from prolonged use

Engineering Contradiction:

Improveaudio listeningVSAvoidinner ear damage and hearing loss

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent uses the skull bone as an intermediary medium to transmit sound vibrations directly to the cochlea, bypassing the eardrum and inner ear structures that are vulnerable to damage from conventional earphones. This bone conduction pathway provides an alternative route for audio transmission that does not expose the inner ear to harmful acoustic pressures.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the acoustic pressure transmission system (used in conventional earphones) with a mechanical vibration transmission system through bone conduction. By transmitting vibrations directly through the skull bone to the cochlea, the system avoids the harmful acoustic pressures that can damage the eardrum and inner ear structures during prolonged use.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present invention discloses a non-surgical bone conduction hearing system (100) and method which can be used either as a hearing aid for hearing loss users as well as an audio device for normal people. The hearing system (100) comprises a hearing device (102) and an adhesive member (106). Further, the hearing device (102) comprises a female mating member (104) and the adhesive member (106) comprises a male mating member (108). The adhesive member (106) may comprise an adhesive surface on other side which is attached behind the ear of the user. The female mating member (104) of the hearing device (102) is connected to the male mating member (108) of the adhesive member (106). Thus, using the hearing system (100), the audio signals are processed and transmitted through vibrations into the hearing organ via bone conduction.
