Solution Overview

Problem

Conventional smart glasses offer limited functionality and user engagement, being costly and heavy, with minimal additional features beyond music playback and phone calls.

Innovation Solution

Smart glasses equipped with temples, sound pickup devices, speakers, and a wireless communication module, allowing real-time hearing assistance by obtaining voice data from a specific direction, amplifying it, and playing it through speakers on different temples, reducing echo and improving sound quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional smart glasses are designed with basic functions (music playback and phone calls), then the device structure remains simple, but the functionality is limited and user engagement is minimal

Engineering Contradiction:

ImprovefunctionalityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The smart glasses are designed to perform multiple functions including music playback, phone calls, and real-time hearing assistance through voice amplification. The wireless communication module and sound processing capabilities enable the device to serve both entertainment and accessibility purposes, making it universally applicable to diverse user needs without requiring separate dedicated devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If smart glasses add real-time hearing assistance function with microphones and speakers, then user engagement is enhanced, but the weight and power consumption increase

Engineering Contradiction:

Improvehearing assistance functionVSAvoidglasses weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

Instead of distributing audio components uniformly across both temples, the patent places the microphone and speaker components strategically on only one temple. This localized arrangement provides the necessary hearing assistance functionality while minimizing the additional weight compared to a symmetric dual-sided configuration

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If smart glasses include voice amplification components, then hearing assistance is provided, but power consumption increases

Engineering Contradiction:

Improvevoice amplification capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The voice amplification function operates periodically rather than continuously - activating only when voice input is detected and requiring amplification output. The wireless communication module processes and amplifies voice data on-demand, allowing the device to conserve power during non-voice-assistance periods while providing hearing assistance when needed

Inventive Principle:

Principle #19Periodic action

4Device complexity

If microphone and speaker are disposed on the same temple, then device structure is simplified, but echo is generated and sound quality deteriorates

Engineering Contradiction:

Improvecomponent arrangementVSAvoidecho

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent employs asymmetric placement of audio components by positioning the microphone and speaker on opposite temples rather than symmetrically on the same temple. This asymmetric arrangement creates physical separation between the sound pickup and output locations, effectively reducing echo feedback while maintaining a relatively simple overall device structure

Inventive Principle:

Principle #4Asymmetry

AI summary

Smart glasses for hearing assistance, a hearing assistance method, and an auxiliary system are provided. The smart glasses include two temples, a sound pickup device, a plurality of speakers and a wireless communication module. The sound pickup device includes at least one microphone, which is configured to obtain first voice data from a first preset direction. The wireless communication module is configured to amplify the first voice data to obtain amplified voice data, and send the amplified voice data to a target speaker for playing. The target speaker and the at least one microphone are respectively disposed on different temples. The present disclosure realizes a real-time hearing assistance function based on the smart glasses, thereby enhancing user engagement.
