Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional communication technologies fail to automatically detect and mitigate background noise during calls, leading to disruptions and quality issues when users are unaware that inappropriate sounds are being transmitted.

Innovation Solution

A system that analyzes audio and video signals in real-time to identify background noise, providing notifications or automatically muting the user to suppress such noise, using voice activity detection and volume level analysis to determine the presence of background noise and its appropriateness for transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If automatic background noise detection and mitigation is implemented, then call quality is improved, but device complexity increases

Engineering Contradiction:

Improvecall qualityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically detects background noise and performs mitigation without requiring manual user intervention. The noise detection module continuously monitors audio signals and automatically triggers muting or notification actions when background noise is detected, allowing the system to serve itself in maintaining call quality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual user actions (mechanically pressing mute buttons) with automated electronic detection and control systems. Voice activity detection algorithms and automated control logic substitute for human judgment and manual operation, reducing the perceived complexity for users while maintaining call quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If manual muting by users is required, then user awareness of background noise is improved, but productivity decreases due to user intervention

Engineering Contradiction:

Improveuser awarenessVSAvoidcall efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The system provides feedback to users through notifications when background noise is detected. The notification module informs users of the detected noise and prompts them to mute if necessary, creating a feedback loop that maintains user awareness while allowing automated assistance.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs partial automation by handling noise detection automatically while leaving the final muting decision to the user through notifications. This partial action approach maintains user control and awareness while reducing the burden of complete manual monitoring.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If automatic muting is performed without user action, then call quality is improved, but ease of operation decreases

Engineering Contradiction:

Improvecall qualityVSAvoiduser control

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts its level of automation based on the situation. It can operate in different modes: providing notifications for user decision-making, or performing automatic muting when configured to do so. This dynamic behavior allows the system to adapt between maintaining call quality and preserving user control.

Inventive Principle:

Principle #15Dynamics
